Minreq

Simple, minimal-dependency HTTP client. The library has a very minimal API, so you'll probably know everything you need to after reading a few examples.

HTTPS

Since the crate is supposed to be minimal in terms of dependencies, HTTPS is a feature on its own, as it requires the (very good) rustls crate. To be able to send HTTPS requests, you need to change your Cargo.toml's [dependencies] part to something like the following:

minreq = { version = "*", features = ["https"] }

Examples

Get

// This is a simple example of sending a GET request and
// printing out the response.
if let Ok(response) = minreq::get("http://httpbin.org/ip").send() {
    println!("{}", response.body);
}

Body

// To include a body, add .with_body("") before .send().
if let Ok(response) = minreq::post("http://httpbin.org/post")
    .with_body("Pong!")
    .send()
{
    println!("{}", response.body);
}

Headers

// To add a header, add .with_header("Key", "Value") before .send().
if let Ok(response) = minreq::get("http://httpbin.org/headers")
    .with_header("Accept", "text/plain")
    .with_header("Something", "Interesting")
    .send()
{
    println!("{}", response.body);
}

Timeouts

// To avoid timing out, or limit the request's response time even more,
// use .with_timeout(n) before .send(). The given value is in seconds.
// NOTE: There is no timeout by default.
if let Ok(response) = minreq::post("http://httpbin.org/delay/6")
    .with_timeout(10)
    .send()
{
    println!("{}", response.body);
}

Timeouts

By default, a request has no timeout. You can change this in two ways:

• Use this function (create_request) and call with_timeout on it to set the timeout per-request like so:

  minreq::get("/").with_timeout(8).send();
  

• Set the environment variable MINREQ_TIMEOUT to the desired amount of seconds until timeout. Ie. if you have a program called foo that uses minreq, and you want all the requests made by that program to timeout in 8 seconds, you launch the program like so:

  $ MINREQ_TIMEOUT=8 ./foo
  

  Or add the following somewhere before the requests in the code.

  use std::env;
  
  env::set_var("MINREQ_TIMEOUT", "8");
