Struct hyper::client::Client

source · [−]

pub struct Client<C, B = Body> { /* private fields */ }

Available on (crate features http1 or http2) and crate feature client only.

Expand description

A Client to make outgoing HTTP requests.

Client is cheap to clone and cloning is the recommended way to share a Client. The underlying connection pool will be reused.

Implementations

impl Client<HttpConnector, Body>

pub fn new() -> Client<HttpConnector, Body>

Available on crate feature tcp only.

Create a new Client with the default config.

Note

The default connector does not handle TLS. Speaking to https destinations will require configuring a connector that implements TLS.

impl Client<(), Body>

pub fn builder() -> Builder

Create a builder to configure a new Client.

Example

use std::time::Duration;
use hyper::Client;

let client = Client::builder()
    .pool_idle_timeout(Duration::from_secs(30))
    .http2_only(true)
    .build_http();

impl<C, B> Client<C, B>where
    C: Connect + Clone + Send + Sync + 'static,
    B: HttpBody + Send + 'static,
    B::Data: Send,
    B::Error: Into<Box<dyn StdError + Send + Sync>>,

pub fn get(&self, uri: Uri) -> ResponseFutureⓘNotable traits for ResponseFuture`impl Future for ResponseFuture type Output = Result<Response<Body>>;`where
B: Default,

Send a GET request to the supplied Uri.

Note

This requires that the HttpBody type have a Default implementation. It should return an “empty” version of itself, such that HttpBody::is_end_stream is true.

Example

use hyper::{Client, Uri};

let client = Client::new();

let future = client.get(Uri::from_static("http://httpbin.org/ip"));

pub fn request(&self, req: Request<B>) -> ResponseFutureⓘNotable traits for ResponseFuture`impl Future for ResponseFuture type Output = Result<Response<Body>>;`

Send a constructed Request using this Client.

Example

use hyper::{Body, Method, Client, Request};

let client = Client::new();

let req = Request::builder()
    .method(Method::POST)
    .uri("http://httpbin.org/post")
    .body(Body::from("Hallo!"))
    .expect("request builder");

let future = client.request(req);
