Struct url::Url

source · [−]
pub struct Url { /* private fields */ }
Expand description

A parsed URL record.

Implementations

Parse an absolute URL from a string.

Examples
use url::Url;

let url = Url::parse("https://example.net")?;
Errors

If the function can not parse an absolute URL from the given string, a ParseError variant will be returned.

Parse an absolute URL from a string and add params to its query string.

Existing params are not removed.

Examples
use url::Url;

let url = Url::parse_with_params("https://example.net?dont=clobberme",
                                 &[("lang", "rust"), ("browser", "servo")])?;
assert_eq!("https://example.net/?dont=clobberme&lang=rust&browser=servo", url.as_str());
Errors

If the function can not parse an absolute URL from the given string, a ParseError variant will be returned.

Parse a string as an URL, with this URL as the base URL.

The inverse of this is make_relative.

Note: a trailing slash is significant. Without it, the last path component is considered to be a “file” name to be removed to get at the “directory” that is used as the base:

Examples
use url::Url;

let base = Url::parse("https://example.net/a/b.html")?;
let url = base.join("c.png")?;
assert_eq!(url.as_str(), "https://example.net/a/c.png");  // Not /a/b.html/c.png

let base = Url::parse("https://example.net/a/b/")?;
let url = base.join("c.png")?;
assert_eq!(url.as_str(), "https://example.net/a/b/c.png");
Errors

If the function can not parse an URL from the given string with this URL as the base URL, a ParseError variant will be returned.

Creates a relative URL if possible, with this URL as the base URL.

This is the inverse of join.

Examples
use url::Url;

let base = Url::parse("https://example.net/a/b.html")?;
let url = Url::parse("https://example.net/a/c.png")?;
let relative = base.make_relative(&url);
assert_eq!(relative.as_ref().map(|s| s.as_str()), Some("c.png"));

let base = Url::parse("https://example.net/a/b/")?;
let url = Url::parse("https://example.net/a/b/c.png")?;
let relative = base.make_relative(&url);
assert_eq!(relative.as_ref().map(|s| s.as_str()), Some("c.png"));

let base = Url::parse("https://example.net/a/b/")?;
let url = Url::parse("https://example.net/a/d/c.png")?;
let relative = base.make_relative(&url);
assert_eq!(relative.as_ref().map(|s| s.as_str()), Some("../d/c.png"));

let base = Url::parse("https://example.net/a/b.html?c=d")?;
let url = Url::parse("https://example.net/a/b.html?e=f")?;
let relative = base.make_relative(&url);
assert_eq!(relative.as_ref().map(|s| s.as_str()), Some("?e=f"));
Errors

If this URL can’t be a base for the given URL, None is returned. This is for example the case if the scheme, host or port are not the same.

Return a default ParseOptions that can fully configure the URL parser.

Examples

Get default ParseOptions, then change base url

use url::Url;
let options = Url::options();
let api = Url::parse("https://api.example.com")?;
let base_url = options.base_url(Some(&api));
let version_url = base_url.parse("version.json")?;
assert_eq!(version_url.as_str(), "https://api.example.com/version.json");

Return the serialization of this URL.

This is fast since that serialization is already stored in the Url struct.

Examples
use url::Url;

let url_str = "https://example.net/";
let url = Url::parse(url_str)?;
assert_eq!(url.as_str(), url_str);
👎 Deprecated since 2.3.0:

use Into<String>

Return the serialization of this URL.

This consumes the Url and takes ownership of the String stored in it.

Examples
use url::Url;

let url_str = "https://example.net/";
let url = Url::parse(url_str)?;
assert_eq!(String::from(url), url_str);

Return the origin of this URL (https://url.spec.whatwg.org/#origin)

Note: this returns an opaque origin for file: URLs, which causes url.origin() != url.origin().

Examples

URL with ftp scheme:

use url::{Host, Origin, Url};

let url = Url::parse("ftp://example.com/foo")?;
assert_eq!(url.origin(),
           Origin::Tuple("ftp".into(),
                         Host::Domain("example.com".into()),
                         21));

URL with blob scheme:

use url::{Host, Origin, Url};

let url = Url::parse("blob:https://example.com/foo")?;
assert_eq!(url.origin(),
           Origin::Tuple("https".into(),
                         Host::Domain("example.com".into()),
                         443));

URL with file scheme:

use url::{Host, Origin, Url};

let url = Url::parse("file:///tmp/foo")?;
assert!(!url.origin().is_tuple());

let other_url = Url::parse("file:///tmp/foo")?;
assert!(url.origin() != other_url.origin());

URL with other scheme:

use url::{Host, Origin, Url};

let url = Url::parse("foo:bar")?;
assert!(!url.origin().is_tuple());

Return the scheme of this URL, lower-cased, as an ASCII string without the ‘:’ delimiter.

Examples
use url::Url;

let url = Url::parse("file:///tmp/foo")?;
assert_eq!(url.scheme(), "file");

Return whether the URL has an ‘authority’, which can contain a username, password, host, and port number.

URLs that do not are either path-only like unix:/run/foo.socket or cannot-be-a-base like data:text/plain,Stuff.

Examples
use url::Url;

let url = Url::parse("ftp://rms@example.com")?;
assert!(url.has_authority());

let url = Url::parse("unix:/run/foo.socket")?;
assert!(!url.has_authority());

let url = Url::parse("data:text/plain,Stuff")?;
assert!(!url.has_authority());

Return whether this URL is a cannot-be-a-base URL, meaning that parsing a relative URL string with this URL as the base will return an error.

This is the case if the scheme and : delimiter are not followed by a / slash, as is typically the case of data: and mailto: URLs.

Examples
use url::Url;

let url = Url::parse("ftp://rms@example.com")?;
assert!(!url.cannot_be_a_base());

let url = Url::parse("unix:/run/foo.socket")?;
assert!(!url.cannot_be_a_base());

let url = Url::parse("data:text/plain,Stuff")?;
assert!(url.cannot_be_a_base());

Return the username for this URL (typically the empty string) as a percent-encoded ASCII string.

Examples
use url::Url;

let url = Url::parse("ftp://rms@example.com")?;
assert_eq!(url.username(), "rms");

let url = Url::parse("ftp://:secret123@example.com")?;
assert_eq!(url.username(), "");

let url = Url::parse("https://example.com")?;
assert_eq!(url.username(), "");

Return the password for this URL, if any, as a percent-encoded ASCII string.

Examples
use url::Url;

let url = Url::parse("ftp://rms:secret123@example.com")?;
assert_eq!(url.password(), Some("secret123"));

let url = Url::parse("ftp://:secret123@example.com")?;
assert_eq!(url.password(), Some("secret123"));

let url = Url::parse("ftp://rms@example.com")?;
assert_eq!(url.password(), None);

let url = Url::parse("https://example.com")?;
assert_eq!(url.password(), None);

Equivalent to url.host().is_some().

Examples
use url::Url;

let url = Url::parse("ftp://rms@example.com")?;
assert!(url.has_host());

let url = Url::parse("unix:/run/foo.socket")?;
assert!(!url.has_host());

let url = Url::parse("data:text/plain,Stuff")?;
assert!(!url.has_host());

Return the string representation of the host (domain or IP address) for this URL, if any.

Non-ASCII domains are punycode-encoded per IDNA if this is the host of a special URL, or percent encoded for non-special URLs. IPv6 addresses are given between [ and ] brackets.

Cannot-be-a-base URLs (typical of data: and mailto:) and some file: URLs don’t have a host.

See also the host method.

Examples
use url::Url;

let url = Url::parse("https://127.0.0.1/index.html")?;
assert_eq!(url.host_str(), Some("127.0.0.1"));

let url = Url::parse("ftp://rms@example.com")?;
assert_eq!(url.host_str(), Some("example.com"));

let url = Url::parse("unix:/run/foo.socket")?;
assert_eq!(url.host_str(), None);

let url = Url::parse("data:text/plain,Stuff")?;
assert_eq!(url.host_str(), None);

Return the parsed representation of the host for this URL. Non-ASCII domain labels are punycode-encoded per IDNA if this is the host of a special URL, or percent encoded for non-special URLs.

Cannot-be-a-base URLs (typical of data: and mailto:) and some file: URLs don’t have a host.

See also the host_str method.

Examples
use url::Url;

let url = Url::parse("https://127.0.0.1/index.html")?;
assert!(url.host().is_some());

let url = Url::parse("ftp://rms@example.com")?;
assert!(url.host().is_some());

let url = Url::parse("unix:/run/foo.socket")?;
assert!(url.host().is_none());

let url = Url::parse("data:text/plain,Stuff")?;
assert!(url.host().is_none());

If this URL has a host and it is a domain name (not an IP address), return it. Non-ASCII domains are punycode-encoded per IDNA if this is the host of a special URL, or percent encoded for non-special URLs.

Examples
use url::Url;

let url = Url::parse("https://127.0.0.1/")?;
assert_eq!(url.domain(), None);

let url = Url::parse("mailto:rms@example.net")?;
assert_eq!(url.domain(), None);

let url = Url::parse("https://example.com/")?;
assert_eq!(url.domain(), Some("example.com"));

Return the port number for this URL, if any.

Note that default port numbers are never reflected by the serialization, use the port_or_known_default() method if you want a default port number returned.

Examples
use url::Url;

let url = Url::parse("https://example.com")?;
assert_eq!(url.port(), None);

let url = Url::parse("https://example.com:443/")?;
assert_eq!(url.port(), None);

let url = Url::parse("ssh://example.com:22")?;
assert_eq!(url.port(), Some(22));

Return the port number for this URL, or the default port number if it is known.

This method only knows the default port number of the http, https, ws, wss and ftp schemes.

For URLs in these schemes, this method always returns Some(_). For other schemes, it is the same as Url::port().

Examples
use url::Url;

let url = Url::parse("foo://example.com")?;
assert_eq!(url.port_or_known_default(), None);

let url = Url::parse("foo://example.com:1456")?;
assert_eq!(url.port_or_known_default(), Some(1456));

let url = Url::parse("https://example.com")?;
assert_eq!(url.port_or_known_default(), Some(443));

Resolve a URL’s host and port number to SocketAddr.

If the URL has the default port number of a scheme that is unknown to this library, default_port_number provides an opportunity to provide the actual port number. In non-example code this should be implemented either simply as || None, or by matching on the URL’s .scheme().

If the host is a domain, it is resolved using the standard library’s DNS support.

Examples
let url = url::Url::parse("https://example.net/").unwrap();
let addrs = url.socket_addrs(|| None).unwrap();
std::net::TcpStream::connect(&*addrs)
/// With application-specific known default port numbers
fn socket_addrs(url: url::Url) -> std::io::Result<Vec<std::net::SocketAddr>> {
    url.socket_addrs(|| match url.scheme() {
        "socks5" | "socks5h" => Some(1080),
        _ => None,
    })
}

Return the path for this URL, as a percent-encoded ASCII string. For cannot-be-a-base URLs, this is an arbitrary string that doesn’t start with ‘/’. For other URLs, this starts with a ‘/’ slash and continues with slash-separated path segments.

Examples
use url::{Url, ParseError};

let url = Url::parse("https://example.com/api/versions?page=2")?;
assert_eq!(url.path(), "/api/versions");

let url = Url::parse("https://example.com")?;
assert_eq!(url.path(), "/");

let url = Url::parse("https://example.com/countries/việt nam")?;
assert_eq!(url.path(), "/countries/vi%E1%BB%87t%20nam");

Unless this URL is cannot-be-a-base, return an iterator of ‘/’ slash-separated path segments, each as a percent-encoded ASCII string.

Return None for cannot-be-a-base URLs.

When Some is returned, the iterator always contains at least one string (which may be empty).

Examples
use url::Url;

let url = Url::parse("https://example.com/foo/bar")?;
let mut path_segments = url.path_segments().ok_or_else(|| "cannot be base")?;
assert_eq!(path_segments.next(), Some("foo"));
assert_eq!(path_segments.next(), Some("bar"));
assert_eq!(path_segments.next(), None);

let url = Url::parse("https://example.com")?;
let mut path_segments = url.path_segments().ok_or_else(|| "cannot be base")?;
assert_eq!(path_segments.next(), Some(""));
assert_eq!(path_segments.next(), None);

let url = Url::parse("data:text/plain,HelloWorld")?;
assert!(url.path_segments().is_none());

let url = Url::parse("https://example.com/countries/việt nam")?;
let mut path_segments = url.path_segments().ok_or_else(|| "cannot be base")?;
assert_eq!(path_segments.next(), Some("countries"));
assert_eq!(path_segments.next(), Some("vi%E1%BB%87t%20nam"));

Return this URL’s query string, if any, as a percent-encoded ASCII string.

Examples
use url::Url;

fn run() -> Result<(), ParseError> {
let url = Url::parse("https://example.com/products?page=2")?;
let query = url.query();
assert_eq!(query, Some("page=2"));

let url = Url::parse("https://example.com/products")?;
let query = url.query();
assert!(query.is_none());

let url = Url::parse("https://example.com/?country=español")?;
let query = url.query();
assert_eq!(query, Some("country=espa%C3%B1ol"));

Parse the URL’s query string, if any, as application/x-www-form-urlencoded and return an iterator of (key, value) pairs.

Examples
use std::borrow::Cow;

use url::Url;

let url = Url::parse("https://example.com/products?page=2&sort=desc")?;
let mut pairs = url.query_pairs();

assert_eq!(pairs.count(), 2);

assert_eq!(pairs.next(), Some((Cow::Borrowed("page"), Cow::Borrowed("2"))));
assert_eq!(pairs.next(), Some((Cow::Borrowed("sort"), Cow::Borrowed("desc"))));

Return this URL’s fragment identifier, if any.

A fragment is the part of the URL after the # symbol. The fragment is optional and, if present, contains a fragment identifier that identifies a secondary resource, such as a section heading of a document.

In HTML, the fragment identifier is usually the id attribute of a an element that is scrolled to on load. Browsers typically will not send the fragment portion of a URL to the server.

Note: the parser did not percent-encode this component, but the input may have been percent-encoded already.

Examples
use url::Url;

let url = Url::parse("https://example.com/data.csv#row=4")?;

assert_eq!(url.fragment(), Some("row=4"));

let url = Url::parse("https://example.com/data.csv#cell=4,1-6,2")?;

assert_eq!(url.fragment(), Some("cell=4,1-6,2"));

Change this URL’s fragment identifier.

Examples
use url::Url;

let mut url = Url::parse("https://example.com/data.csv")?;
assert_eq!(url.as_str(), "https://example.com/data.csv");
url.set_fragment(Some("cell=4,1-6,2"));
assert_eq!(url.as_str(), "https://example.com/data.csv#cell=4,1-6,2");
assert_eq!(url.fragment(), Some("cell=4,1-6,2"));

url.set_fragment(None);
assert_eq!(url.as_str(), "https://example.com/data.csv");
assert!(url.fragment().is_none());

Change this URL’s query string.

Examples
use url::Url;

let mut url = Url::parse("https://example.com/products")?;
assert_eq!(url.as_str(), "https://example.com/products");

url.set_query(Some("page=2"));
assert_eq!(url.as_str(), "https://example.com/products?page=2");
assert_eq!(url.query(), Some("page=2"));

Manipulate this URL’s query string, viewed as a sequence of name/value pairs in application/x-www-form-urlencoded syntax.

The return value has a method-chaining API:


let mut url = Url::parse("https://example.net?lang=fr#nav")?;
assert_eq!(url.query(), Some("lang=fr"));

url.query_pairs_mut().append_pair("foo", "bar");
assert_eq!(url.query(), Some("lang=fr&foo=bar"));
assert_eq!(url.as_str(), "https://example.net/?lang=fr&foo=bar#nav");

url.query_pairs_mut()
    .clear()
    .append_pair("foo", "bar & baz")
    .append_pair("saisons", "\u{00C9}t\u{00E9}+hiver");
assert_eq!(url.query(), Some("foo=bar+%26+baz&saisons=%C3%89t%C3%A9%2Bhiver"));
assert_eq!(url.as_str(),
           "https://example.net/?foo=bar+%26+baz&saisons=%C3%89t%C3%A9%2Bhiver#nav");

Note: url.query_pairs_mut().clear(); is equivalent to url.set_query(Some("")), not url.set_query(None).

The state of Url is unspecified if this return value is leaked without being dropped.

Change this URL’s path.

Examples
use url::Url;

let mut url = Url::parse("https://example.com")?;
url.set_path("api/comments");
assert_eq!(url.as_str(), "https://example.com/api/comments");
assert_eq!(url.path(), "/api/comments");

let mut url = Url::parse("https://example.com/api")?;
url.set_path("data/report.csv");
assert_eq!(url.as_str(), "https://example.com/data/report.csv");
assert_eq!(url.path(), "/data/report.csv");

Return an object with methods to manipulate this URL’s path segments.

Return Err(()) if this URL is cannot-be-a-base.

Change this URL’s port number.

Note that default port numbers are not reflected in the serialization.

If this URL is cannot-be-a-base, does not have a host, or has the file scheme; do nothing and return Err.

Examples
use url::Url;

let mut url = Url::parse("ssh://example.net:2048/")?;

url.set_port(Some(4096)).map_err(|_| "cannot be base")?;
assert_eq!(url.as_str(), "ssh://example.net:4096/");

url.set_port(None).map_err(|_| "cannot be base")?;
assert_eq!(url.as_str(), "ssh://example.net/");

Known default port numbers are not reflected:

use url::Url;

let mut url = Url::parse("https://example.org/")?;

url.set_port(Some(443)).map_err(|_| "cannot be base")?;
assert!(url.port().is_none());

Cannot set port for cannot-be-a-base URLs:

use url::Url;

let mut url = Url::parse("mailto:rms@example.net")?;

let result = url.set_port(Some(80));
assert!(result.is_err());

let result = url.set_port(None);
assert!(result.is_err());

Change this URL’s host.

Removing the host (calling this with None) will also remove any username, password, and port number.

Examples

Change host:

use url::Url;

let mut url = Url::parse("https://example.net")?;
let result = url.set_host(Some("rust-lang.org"));
assert!(result.is_ok());
assert_eq!(url.as_str(), "https://rust-lang.org/");

Remove host:

use url::Url;

let mut url = Url::parse("foo://example.net")?;
let result = url.set_host(None);
assert!(result.is_ok());
assert_eq!(url.as_str(), "foo:/");

Cannot remove host for ‘special’ schemes (e.g. http):

use url::Url;

let mut url = Url::parse("https://example.net")?;
let result = url.set_host(None);
assert!(result.is_err());
assert_eq!(url.as_str(), "https://example.net/");

Cannot change or remove host for cannot-be-a-base URLs:

use url::Url;

let mut url = Url::parse("mailto:rms@example.net")?;

let result = url.set_host(Some("rust-lang.org"));
assert!(result.is_err());
assert_eq!(url.as_str(), "mailto:rms@example.net");

let result = url.set_host(None);
assert!(result.is_err());
assert_eq!(url.as_str(), "mailto:rms@example.net");
Errors

If this URL is cannot-be-a-base or there is an error parsing the given host, a ParseError variant will be returned.

Change this URL’s host to the given IP address.

If this URL is cannot-be-a-base, do nothing and return Err.

Compared to Url::set_host, this skips the host parser.

Examples
use url::{Url, ParseError};

let mut url = Url::parse("http://example.com")?;
url.set_ip_host("127.0.0.1".parse().unwrap());
assert_eq!(url.host_str(), Some("127.0.0.1"));
assert_eq!(url.as_str(), "http://127.0.0.1/");

Cannot change URL’s from mailto(cannot-be-base) to ip:

use url::{Url, ParseError};

let mut url = Url::parse("mailto:rms@example.com")?;
let result = url.set_ip_host("127.0.0.1".parse().unwrap());

assert_eq!(url.as_str(), "mailto:rms@example.com");
assert!(result.is_err());

Change this URL’s password.

If this URL is cannot-be-a-base or does not have a host, do nothing and return Err.

Examples
use url::{Url, ParseError};

let mut url = Url::parse("mailto:rmz@example.com")?;
let result = url.set_password(Some("secret_password"));
assert!(result.is_err());

let mut url = Url::parse("ftp://user1:secret1@example.com")?;
let result = url.set_password(Some("secret_password"));
assert_eq!(url.password(), Some("secret_password"));

let mut url = Url::parse("ftp://user2:@example.com")?;
let result = url.set_password(Some("secret2"));
assert!(result.is_ok());
assert_eq!(url.password(), Some("secret2"));

Change this URL’s username.

If this URL is cannot-be-a-base or does not have a host, do nothing and return Err.

Examples

Cannot setup username from mailto(cannot-be-base)

use url::{Url, ParseError};

let mut url = Url::parse("mailto:rmz@example.com")?;
let result = url.set_username("user1");
assert_eq!(url.as_str(), "mailto:rmz@example.com");
assert!(result.is_err());

Setup username to user1

use url::{Url, ParseError};

let mut url = Url::parse("ftp://:secre1@example.com/")?;
let result = url.set_username("user1");
assert!(result.is_ok());
assert_eq!(url.username(), "user1");
assert_eq!(url.as_str(), "ftp://user1:secre1@example.com/");

Change this URL’s scheme.

Do nothing and return Err under the following circumstances:

  • If the new scheme is not in [a-zA-Z][a-zA-Z0-9+.-]+
  • If this URL is cannot-be-a-base and the new scheme is one of http, https, ws, wss or ftp
  • If either the old or new scheme is http, https, ws, wss or ftp and the other is not one of these
  • If the new scheme is file and this URL includes credentials or has a non-null port
  • If this URL’s scheme is file and its host is empty or null

See also the URL specification’s section on legal scheme state overrides.

Examples

Change the URL’s scheme from https to foo:

use url::Url;

let mut url = Url::parse("https://example.net")?;
let result = url.set_scheme("http");
assert_eq!(url.as_str(), "http://example.net/");
assert!(result.is_ok());

Change the URL’s scheme from foo to bar:

use url::Url;

let mut url = Url::parse("foo://example.net")?;
let result = url.set_scheme("bar");
assert_eq!(url.as_str(), "bar://example.net");
assert!(result.is_ok());

Cannot change URL’s scheme from https to foõ:

use url::Url;

let mut url = Url::parse("https://example.net")?;
let result = url.set_scheme("foõ");
assert_eq!(url.as_str(), "https://example.net/");
assert!(result.is_err());

Cannot change URL’s scheme from mailto (cannot-be-a-base) to https:

use url::Url;

let mut url = Url::parse("mailto:rms@example.net")?;
let result = url.set_scheme("https");
assert_eq!(url.as_str(), "mailto:rms@example.net");
assert!(result.is_err());

Cannot change the URL’s scheme from foo to https:

use url::Url;

let mut url = Url::parse("foo://example.net")?;
let result = url.set_scheme("https");
assert_eq!(url.as_str(), "foo://example.net");
assert!(result.is_err());

Cannot change the URL’s scheme from http to foo:

use url::Url;

let mut url = Url::parse("http://example.net")?;
let result = url.set_scheme("foo");
assert_eq!(url.as_str(), "http://example.net/");
assert!(result.is_err());

Convert a file name as std::path::Path into an URL in the file scheme.

This returns Err if the given path is not absolute or, on Windows, if the prefix is not a disk prefix (e.g. C:) or a UNC prefix (\\).

Examples

On Unix-like platforms:

use url::Url;

let url = Url::from_file_path("/tmp/foo.txt")?;
assert_eq!(url.as_str(), "file:///tmp/foo.txt");

let url = Url::from_file_path("../foo.txt");
assert!(url.is_err());

let url = Url::from_file_path("https://google.com/");
assert!(url.is_err());

Convert a directory name as std::path::Path into an URL in the file scheme.

This returns Err if the given path is not absolute or, on Windows, if the prefix is not a disk prefix (e.g. C:) or a UNC prefix (\\).

Compared to from_file_path, this ensure that URL’s the path has a trailing slash so that the entire path is considered when using this URL as a base URL.

For example:

  • "index.html" parsed with Url::from_directory_path(Path::new("/var/www")) as the base URL is file:///var/www/index.html
  • "index.html" parsed with Url::from_file_path(Path::new("/var/www")) as the base URL is file:///var/index.html, which might not be what was intended.

Note that std::path does not consider trailing slashes significant and usually does not include them (e.g. in Path::parent()).

Assuming the URL is in the file scheme or similar, convert its path to an absolute std::path::Path.

Note: This does not actually check the URL’s scheme, and may give nonsensical results for other schemes. It is the user’s responsibility to check the URL’s scheme before calling this.

let path = url.to_file_path();

Returns Err if the host is neither empty nor "localhost" (except on Windows, where file: URLs may have a non-local host), or if Path::new_opt() returns None. (That is, if the percent-decoded path contains a NUL byte or, for a Windows path, is not UTF-8.)
