Module hyper::client[−][src]

HTTP Client

There are two levels of APIs provided for construct HTTP clients:

The higher-level Client type.
The lower-level conn module.

Client

The Client is the main way to send HTTP requests to a server. The default Client provides these things on top of the lower-level API:

A default connector, able to resolve hostnames and connect to destinations over plain-text TCP.
A pool of existing connections, allowing better performance when making multiple requests to the same hostname.
Automatic setting of the Host header, based on the request Uri.
Automatic request retries when a pooled connection is closed by the server before any bytes have been written.

Many of these features can configured, by making use of Client::builder.

Example

For a small example program simply fetching a URL, take a look at the full client example.

use hyper::{body::HttpBody as _, Client, Uri};

let client = Client::new();

// Make a GET /ip to 'http://httpbin.org'
let res = client.get(Uri::from_static("http://httpbin.org/ip")).await?;

// And then, if the request gets a response...
println!("status: {}", res.status());

// Concatenate the body stream into a single buffer...
let buf = hyper::body::to_bytes(res).await?;

println!("body: {:?}", buf);
