Struct Client

Source

pub struct Client { /* private fields */ }

Available on crate feature std only.

Expand description

A blocking HTTP/1.1 client: one connection per request.

Setting	Default
limits	`Limits::new` with a 16 MiB body
connect, read, and write timeout	30 s each
total deadline for one exchange (connect, write, read)	none

§Examples

use std::time::Duration;
use http_net::{blocking::Client, Limits};

let client = Client::new()
    .with_limits(Limits::new().with_max_body(64 << 20))
    .with_timeout(Duration::from_secs(5));
let resp = client.get("http://127.0.0.1:8080/big")?;

Implementations§

Source §

impl Client

Source

pub const fn new() -> Self

The defaults (see the table on Client).

§Examples

let _ = http_net::blocking::Client::new();

Source

pub const fn with_limits(self, limits: Limits) -> Self

Sets the response limits.

§Examples

let _ = http_net::blocking::Client::new().with_limits(http_net::Limits::new());

Source

pub const fn with_timeout(self, timeout: Duration) -> Self

Sets the connect, read, and write timeout (zero is raised to 1 ms).

§Examples

let _ = http_net::blocking::Client::new().with_timeout(std::time::Duration::from_secs(2));

Source

pub const fn with_deadline(self, deadline: Option<Duration>) -> Self

Sets a total deadline for one exchange: connecting, writing the request, and reading the whole response. The per-operation timeout of with_timeout cannot stop a server that sends one byte just inside it; this deadline can. None (the default) disables it.

§Examples

use std::time::Duration;
let _ = http_net::blocking::Client::new().with_deadline(Some(Duration::from_secs(10)));

Source

pub fn get(&self, url: &str) -> Result<ClientResponse, Error>

Fetches url with GET.

§Errors

As get.

§Examples

See Client.

Source

pub fn request( &self, url: &str, request: Request, ) -> Result<ClientResponse, Error>

Sends request to the http:// URL url and reads the response. The URL gives the authority (written as host) and the target, which replaces the target request was built with; the method, fields, and body come from request. The request is sent with connection: close on a connection of its own.

§Errors

As get; Error::Http with the builder’s first error; HttpError::InvalidHost when request already has a host (the URL supplies it); HttpError::InvalidState for a streamed body (chunked or content_length: this client sends full bodies) or an upgrade request (it cannot hand the connection over; use ClientConn).

§Examples

use http_net::{blocking::{self, Client}, Request, Response};

let server = blocking::Server::bind("127.0.0.1:0")?;
let addr = server.local_addr();
let stop = server.shutdown_handle();
let t = std::thread::spawn(move || {
    server.serve(|req, body| Response::text(200, &format!("{} {} {}", req.method_str(), req.path(), body.len())))
});

let put = Request::put("/").header("content-type", "application/json").body(&b"{}"[..]);
let resp = Client::new().request(&format!("http://{addr}/items/7"), put)?;
assert_eq!(resp.text(), Some("PUT /items/7 2"));

stop.shutdown();
t.join().unwrap()?;
