Rust http crate create a request with post parameters

Question

I have this;

Request::builder()
 .method(http::Method::POST)
 .uri("/create_mapping")
 .body()

And I want to add POST parameters into the body(). Say something like a=1&b=2.

Answer 1

The easiest way seems to be to use from_urlencoded and do something like:

let encoded = form_urlencoded::Serializer::new(String::new())
            .append_pair("a", "1")
            .append_pair("b", "2")
            .finish();

and then create the body like this: Body::from(encoded)
