Struct openidconnect::RedirectUrl

pub struct RedirectUrl(_);

URL of the client's redirection endpoint.

Methods

impl RedirectUrl

pub fn new(s: Url) -> RedirectUrl

Create a new RedirectUrl to wrap the given Url.

Methods from Deref<Target = Url>

pub fn join(&self, input: &str) -> Result<Url, ParseError>

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

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.

pub fn as_str(&self) -> &str

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);

pub fn origin(&self) -> Origin

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());

pub fn scheme(&self) -> &str

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");

pub fn has_authority(&self) -> bool

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());

pub fn cannot_be_a_base(&self) -> bool

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());

pub fn username(&self) -> &str

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(), "");

pub fn password(&self) -> Option<&str>

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);

pub fn has_host(&self) -> bool

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());

pub fn host_str(&self) -> Option<&str>

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

Non-ASCII domains are punycode-encoded per IDNA. 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);

pub fn host(&self) -> Option<Host<&str>>

Return the parsed representation of the host for this URL. Non-ASCII domain labels are punycode-encoded per IDNA.

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());

pub fn domain(&self) -> Option<&str>

If this URL has a host and it is a domain name (not an IP address), return it.

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"));

pub fn port(&self) -> Option<u16>

Return the port number for this URL, if any.

Examples

use url::Url;

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

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

pub fn port_or_known_default(&self) -> Option<u16>

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, ftp, and gopher 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));

pub fn with_default_port<F>(&self, f: F) -> Result<HostAndPort<&str>, Error> where
    F: FnOnce(&Url) -> Result<u16, ()>, 

If the URL has a host, return something that implements ToSocketAddrs.

If the URL has no port number and the scheme’s default port number is not known (see Url::port_or_known_default), the closure is called to obtain a port number. Typically, this closure can match on the result Url::scheme to have per-scheme default port numbers, and panic for schemes it’s not prepared to handle. For example:

fn connect(url: &Url) -> io::Result<TcpStream> {
    TcpStream::connect(url.with_default_port(default_port)?)
}

fn default_port(url: &Url) -> Result<u16, ()> {
    match url.scheme() {
        "git" => Ok(9418),
        "git+ssh" => Ok(22),
        "git+https" => Ok(443),
        "git+http" => Ok(80),
        _ => Err(()),
    }
}

pub fn path(&self) -> &str

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");

pub fn path_segments(&self) -> Option<Split<char>>

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"));

pub fn query(&self) -> Option<&str>

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"));

pub fn query_pairs(&self) -> Parse

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"))));

pub fn fragment(&self) -> Option<&str>

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"));

pub fn to_file_path(&self) -> Result<PathBuf, ()>

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.)
