Implementations§

Source§

impl Request

Source

pub fn new<U>(method: Method, url: U) -> Self
where U: TryInto<Url>, U::Error: Debug,

Create a new request.

Source

pub fn set_peer_addr(&mut self, peer_addr: Option<impl ToString>)

Sets a string representation of the peer address of this request. This might take the form of an ip/fqdn and port or a local socket address.

Source

pub fn set_local_addr(&mut self, local_addr: Option<impl ToString>)

Sets a string representation of the local address that this request was received on. This might take the form of an ip/fqdn and port, or a local socket address.

Source

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

Get the peer socket address for the underlying transport, if that information is available for this request.

Source

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

Get the local socket address for the underlying transport, if that information is available for this request.

Source

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

  2. The first X-Forwarded-For header
  3. Peer address of the transport
Source

Get the destination host for this request.

This is determined in the following priority:

  1. Forwarded header host key
  2. The first X-Forwarded-Host header
  3. Host header
  4. URL domain, if any
Source

pub fn method(&self) -> Method

Get the HTTP method

Source

pub fn set_method(&mut self, method: Method)

Set the HTTP method.

Source

pub fn url(&self) -> &Url

Get a reference to the url.

§Examples
use http_types::{Request, Response, StatusCode};
let mut req = Request::get("https://example.com");
assert_eq!(req.url().scheme(), "https");
Source

pub fn url_mut(&mut self) -> &mut Url

Get a mutable reference to the url.

§Examples
use http_types::{Method, Request, Response, StatusCode, Url};
let mut req = Request::get("https://example.com");
req.url_mut().set_scheme("http");
assert_eq!(req.url().scheme(), "http");
Source

pub fn set_body(&mut self, body: impl Into<Body>)

Set the request body.

§Examples
use http_types::{Method, Request};

let mut req = Request::get("https://example.com");
req.set_body("Hello, Nori!");
Source

pub fn replace_body(&mut self, body: impl Into<Body>) -> Body

Swaps the value of the body with another body, without deinitializing either one.

§Examples
use http_types::{Body, Method, Request};

let mut req = Request::get("https://example.com");
req.set_body("Hello, Nori!");
let mut body: Body = req.replace_body("Hello, Chashu!");

let mut string = String::new();
body.read_to_string(&mut string).await?;
assert_eq!(&string, "Hello, Nori!");
Source

pub fn swap_body(&mut self, body: &mut Body)

Replace the request body with a new body, and return the old body.

§Examples
use http_types::{Body, Request};

let mut req = Request::get("https://example.com");
req.set_body("Hello, Nori!");
let mut body = "Hello, Chashu!".into();
req.swap_body(&mut body);

let mut string = String::new();
body.read_to_string(&mut string).await?;
assert_eq!(&string, "Hello, Nori!");
Source

pub fn take_body(&mut self) -> Body

Take the request body, replacing it with an empty body.

§Examples
use http_types::{Body, Request};

let mut req = Request::get("https://example.com");
req.set_body("Hello, Nori!");
let mut body: Body = req.take_body();

let mut string = String::new();
body.read_to_string(&mut string).await?;
assert_eq!(&string, "Hello, Nori!");
Source

pub async fn body_string(&mut self) -> Result<String>

Read the body as a string.

This consumes the request. If you want to read the body without consuming the request, consider using the take_body method and then calling Body::into_string or using the Request’s AsyncRead implementation to read the body.

§Examples
use async_std::io::Cursor;
use http_types::{Body, Request};

let mut req = Request::get("https://example.com");

let cursor = Cursor::new("Hello Nori");
let body = Body::from_reader(cursor, None);
req.set_body(body);
assert_eq!(&req.body_string().await.unwrap(), "Hello Nori");
Source

pub async fn body_bytes(&mut self) -> Result<Vec<u8>>

Read the body as bytes.

This consumes the Request. If you want to read the body without consuming the request, consider using the take_body method and then calling Body::into_bytes or using the Request’s AsyncRead implementation to read the body.

§Examples
use http_types::{Body, Request};

let bytes = vec![1, 2, 3];
let mut req = Request::get("https://example.com");
req.set_body(Body::from_bytes(bytes));

let bytes = req.body_bytes().await?;
assert_eq!(bytes, vec![1, 2, 3]);
Source

pub async fn body_json<T: DeserializeOwned>(&mut self) -> Result<T>

Read the body as JSON.

This consumes the request. If you want to read the body without consuming the request, consider using the take_body method and then calling Body::into_json or using the Request’s AsyncRead implementation to read the body.

§Examples
use http_types::convert::{Deserialize, Serialize};
use http_types::{Body, Request};

#[derive(Debug, Serialize, Deserialize)]
struct Cat {
    name: String,
}

let cat = Cat {
    name: String::from("chashu"),
};
let mut req = Request::get("https://example.com");
req.set_body(Body::from_json(&cat)?);

let cat: Cat = req.body_json().await?;
assert_eq!(&cat.name, "chashu");
Source

pub async fn body_form<T: DeserializeOwned>(&mut self) -> Result<T>

Read the body as x-www-form-urlencoded.

This consumes the request. If you want to read the body without consuming the request, consider using the take_body method and then calling Body::into_json or using the Request’s AsyncRead implementation to read the body.

§Examples
use http_types::convert::{Deserialize, Serialize};
use http_types::{Body, Request};

#[derive(Debug, Serialize, Deserialize)]
struct Cat {
    name: String,
}

let cat = Cat {
    name: String::from("chashu"),
};
let mut req = Request::get("https://example.com");
req.set_body(Body::from_form(&cat)?);

let cat: Cat = req.body_form().await?;

Remove a header.

Source

pub fn insert_header( &mut self, name: impl Into<HeaderName>, values: impl ToHeaderValues, ) -> Option<HeaderValues>

Set an HTTP header.

§Examples
use http_types::Request;

let mut req = Request::get("https://example.com");
req.insert_header("Content-Type", "text/plain");
Source

pub fn append_header( &mut self, name: impl Into<HeaderName>, values: impl ToHeaderValues, )

Append a header to the headers.

Unlike insert this function will not override the contents of a header, but insert a header if there aren’t any. Or else append to the existing list of headers.

}

let mut req = Request::get("https://httpbin.org/get?page=2&selections[width]=narrow&selections[height]=tall");
let Index { page, selections } = req.query().unwrap();
assert_eq!(page, 2);
assert_eq!(selections["width"], "narrow");
assert_eq!(selections["height"], "tall");

// Using borrows:

Source

pub fn get<U>(url: U) -> Self
where U: TryInto<Url>, U::Error: Debug,

Source

pub fn post<U>(url: U) -> Self

assert_eq!(req.method(), Method::Put);
Source

pub fn delete<U>(url: U) -> Self
where U: TryInto<Url>, U::Error: Debug,

assert_eq!(req.method(), Method::Delete);
Source

pub fn connect<U>(url: U) -> Self
where U: TryInto<Url>, U::Error: Debug,

assert_eq!(req.method(), Method::Connect);
Source

pub fn options<U>(url: U) -> Self
where U: TryInto<Url>, U::Error: Debug,

use http_types::{Method, Request};

let mut req = Request::options("https://example.com");
assert_eq!(req.method(), Method::Options);
Source

pub fn trace<U>(url: U) -> Self
where U: TryInto<Url>, U::Error: Debug,

Create a TRACE request.

The TRACE method performs a message loop-back test along the path to the target resource.

§Examples
use http_types::{Method, Request};

let mut req = Request::trace("https://example.com");
assert_eq!(req.method(), Method::Trace);
Source

pub fn patch<U>(url: U) -> Self
where U: TryInto<Url>, U::Error: Debug,

Create a PATCH request.

The PATCH method is used to apply partial modifications to a resource.

§Examples
use http_types::{Method, Request};
