Struct reqwest::RequestBuilder [−] [src]

pub struct RequestBuilder { /* fields omitted */ }

A builder to construct the properties of a Request.

Methods

impl RequestBuilder
[src]

Add a Header to this Request.

use reqwest::header::UserAgent;

let client = reqwest::Client::new()?;
let res = client.get("https://www.rust-lang.org")?
    .header(UserAgent::new("foo"))
    .send()?;

Add a set of Headers to the existing ones on this Request.

The headers will be merged in to any already set.

use reqwest::header::{Headers, UserAgent, ContentType};

fn construct_headers() -> Headers {
    let mut headers = Headers::new();
    headers.set(UserAgent::new("reqwest"));
    headers.set(ContentType::png());
    headers
}

let file = fs::File::open("much_beauty.png")?;
let client = reqwest::Client::new()?;
let res = client.post("http://httpbin.org/post")?
    .headers(construct_headers())
    .body(file)
    .send()?;

Enable HTTP basic authentication.

let client = reqwest::Client::new()?;
let resp = client.delete("http://httpbin.org/delete")?
    .basic_auth("admin", Some("good password"))
    .send()?;

Set the request body.

let client = reqwest::Client::new()?;
let res = client.post("http://httpbin.org/post")?
    .body("from a &str!")
    .send()?;
let file = fs::File::open("from_a_file.txt")?;
let client = reqwest::Client::new()?;
let res = client.post("http://httpbin.org/post")?
    .body(file)
    .send()?;
// from bytes!
let bytes: Vec<u8> = vec![1, 10, 100];
let client = reqwest::Client::new()?;
let res = client.post("http://httpbin.org/post")?
    .body(bytes)
    .send()?;

Send a form body.

Sets the body to the url encoded serialization of the passed value, and also sets the Content-Type: application/www-form-url-encoded header.

let mut params = HashMap::new();
params.insert("lang", "rust");

let client = reqwest::Client::new()?;
let res = client.post("http://httpbin.org")?
    .form(&params)?
    .send()?;

Errors

This method fails if the passed value cannot be serialized into url encoded format

Send a JSON body.

Sets the body to the JSON serialization of the passed value, and also sets the Content-Type: application/json header.

let mut map = HashMap::new();
map.insert("lang", "rust");

let client = reqwest::Client::new()?;
let res = client.post("http://httpbin.org")?
    .json(&map)?
    .send()?;

Errors

Serialization can fail if T's implementation of Serialize decides to fail, or if T contains a map with non-string keys.

Build a Request, which can be inspected, modified and executed with Client::execute().

Panics

This method consumes builder internal state. It panics on an attempt to reuse already consumed builder.

Constructs the Request and sends it the target URL, returning a Response.

Errors

This method fails if there was an error while sending request, redirect loop was detected or redirect limit was exhausted.
