Struct http_types::Request[−][src]

pub struct Request { /* fields omitted */ }
Expand description

An HTTP request.

Examples

use http_types::Request;

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

Implementations

Create a new request.

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.

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.

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

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

Get the remote address for this request.

This is determined in the following priority:

  1. Forwarded header for key
  2. The first X-Forwarded-For header
  3. Peer address of the transport

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

Get the HTTP method

Set the HTTP method.

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");

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");
[src]

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!");
[src]

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!");
[src]

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!");
[src]

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!");

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");

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]);

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");

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?;
assert_eq!(&cat.name, "chashu");

Get an HTTP header.

Get a mutable reference to a header.

Remove a header.

Set an HTTP header.

Examples

use http_types::Request;

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

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.

Examples

use http_types::Request;

let mut req = Request::get("https://example.com");
req.append_header("Content-Type", "text/plain");
[src]

pub fn set_content_type(&mut self, mime: Mime) -> Option<HeaderValues>

Set the response MIME.

Get the current content type

Get the length of the body stream, if it has been set.

This value is set when passing a fixed-size object into as the body. E.g. a string, or a buffer. Consumers of this API should check this value to decide whether to use Chunked encoding, or set the response length.

Returns true if the request has a set body stream length of zero, false otherwise.

Get the HTTP version, if one has been set.

Examples

use http_types::{Request, Version};

let mut req = Request::get("https://example.com");
assert_eq!(req.version(), None);

req.set_version(Some(Version::Http2_0));
assert_eq!(req.version(), Some(Version::Http2_0));

Set the HTTP version.

Examples

use http_types::{Request, Version};

let mut req = Request::get("https://example.com");
req.set_version(Some(Version::Http2_0));

Sends trailers to the a receiver.

Receive trailers from a sender.

Returns true if sending trailers is in progress.

An iterator visiting all header pairs in arbitrary order.

An iterator visiting all header pairs in arbitrary order, with mutable references to the values.

An iterator visiting all header names in arbitrary order.

An iterator visiting all header values in arbitrary order.

Returns a reference to the existing local state.

Returns a mutuable reference to the existing local state.

Examples

use http_types::{Request, Version};

let mut req = Request::get("https://example.com");
req.ext_mut().insert("hello from the extension");
assert_eq!(req.ext().get(), Some(&"hello from the extension"));

Get the URL querystring.

Examples

use http_types::convert::Deserialize;
use http_types::Request;
use std::collections::HashMap;

// An owned structure:

#[derive(Deserialize)]
struct Index {
    page: u32,
    selections: HashMap<String, String>,
}

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:

#[derive(Deserialize)]
struct Query<'q> {
    format: &'q str,
}

let mut req = Request::get("https://httpbin.org/get?format=bananna");
let Query { format } = req.query().unwrap();
assert_eq!(format, "bananna");

Set the URL querystring.

Examples

use http_types::convert::Serialize;
use http_types::{Method, Request};
use std::collections::HashMap;

#[derive(Serialize)]
struct Index {
    page: u32,
    topics: Vec<&'static str>,
}

let query = Index { page: 2, topics: vec!["rust", "crabs", "crustaceans"] };
let mut req = Request::get("https://httpbin.org/get");
req.set_query(&query).unwrap();
assert_eq!(req.url().query(), Some("page=2&topics[0]=rust&topics[1]=crabs&topics[2]=crustaceans"));

Create a GET request.

The GET method requests a representation of the specified resource. Requests using GET should only retrieve data.

Examples

use http_types::{Method, Request};

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

Create a HEAD request.

The HEAD method asks for a response identical to that of a GET request, but without the response body.

Examples

use http_types::{Method, Request};

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

Create a POST request.

The POST method is used to submit an entity to the specified resource, often causing a change in state or side effects on the server.

Examples

use http_types::{Method, Request};

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

Create a PUT request.

The PUT method replaces all current representations of the target resource with the request payload.

Examples

use http_types::{Method, Request};

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

Create a DELETE request.

The DELETE method deletes the specified resource.

Examples

use http_types::{Method, Request};

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

Create a CONNECT request.

The CONNECT method establishes a tunnel to the server identified by the target resource.

Examples

use http_types::{Method, Request};

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

Create a OPTIONS request.

The OPTIONS method is used to describe the communication options for the target resource.

Examples

use http_types::{Method, Request};

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

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);

Create a PATCH request.

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

Examples

use http_types::{Method, Request};

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