Struct actix_web::client::ClientRequest

pub struct ClientRequest { /* fields omitted */ }

An HTTP Client request builder

This type can be used to construct an instance of ClientRequest through a builder-like pattern.

use futures::future::{Future, lazy};
use actix_rt::System;

fn main() {
    System::new("test").block_on(lazy(|| {
       awc::Client::new()
          .get("http://www.rust-lang.org") // <- Create request builder
          .header("User-Agent", "Actix-web")
          .send()                          // <- Send http request
          .map_err(|_| ())
          .and_then(|response| {           // <- server http response
               println!("Response: {:?}", response);
               Ok(())
          })
    }));
}

Methods

impl ClientRequest

pub fn uri<U>(self, uri: U) -> ClientRequest where
    Uri: HttpTryFrom<U>, 

Set HTTP URI of request.

pub fn method(self, method: Method) -> ClientRequest

Set HTTP method of this request.

pub fn headers(&self) -> &HeaderMap

Returns request's headers.

pub fn headers_mut(&mut self) -> &mut HeaderMap

Returns request's mutable headers.

pub fn set<H>(self, hdr: H) -> ClientRequest where
    H: Header, 

Set a header.

fn main() {
    let req = awc::Client::new()
        .get("http://www.rust-lang.org")
        .set(awc::http::header::Date::now())
        .set(awc::http::header::ContentType(mime::TEXT_HTML));
}

pub fn header<K, V>(self, key: K, value: V) -> ClientRequest where
    V: IntoHeaderValue,
    HeaderName: HttpTryFrom<K>, 

Append a header.

Header gets appended to existing header. To override header use set_header() method.

use awc::{http, Client};

fn main() {
    let req = Client::new()
        .get("http://www.rust-lang.org")
        .header("X-TEST", "value")
        .header(http::header::CONTENT_TYPE, "application/json");
}

pub fn set_header<K, V>(self, key: K, value: V) -> ClientRequest where
    V: IntoHeaderValue,
    HeaderName: HttpTryFrom<K>, 

Insert a header, replaces existing header.

pub fn set_header_if_none<K, V>(self, key: K, value: V) -> ClientRequest where
    V: IntoHeaderValue,
    HeaderName: HttpTryFrom<K>, 

Insert a header only if it is not yet set.

pub fn force_close(self) -> ClientRequest

Force close connection instead of returning it back to connections pool. This setting affect only http/1 connections.

pub fn content_type<V>(self, value: V) -> ClientRequest where
    HeaderValue: HttpTryFrom<V>, 

Set request's content type

pub fn content_length(self, len: u64) -> ClientRequest

Set content length

pub fn basic_auth<U>(self, username: U, password: Option<&str>) -> ClientRequest where
    U: Display, 

Set HTTP basic authorization header

pub fn bearer_auth<T>(self, token: T) -> ClientRequest where
    T: Display, 

Set HTTP bearer authentication header

pub fn cookie(self, cookie: Cookie<'c>) -> ClientRequest

Set a cookie

fn main() {
    System::new("test").block_on(lazy(|| {
        awc::Client::new().get("https://www.rust-lang.org")
            .cookie(
                awc::http::Cookie::build("name", "value")
                    .domain("www.rust-lang.org")
                    .path("/")
                    .secure(true)
                    .http_only(true)
                    .finish(),
            )
            .send()
            .map_err(|_| ())
            .and_then(|response| {
               println!("Response: {:?}", response);
               Ok(())
            })
    }));
}

pub fn no_default_headers(self) -> ClientRequest

Do not add default request headers. By default Date and User-Agent headers are set.

pub fn no_decompress(self) -> ClientRequest

Disable automatic decompress of response's body

pub fn timeout(self, timeout: Duration) -> ClientRequest

Set request timeout. Overrides client wide timeout setting.

Request timeout is the total time before a response must be received. Default value is 5 seconds.

pub fn if_true<F>(self, value: bool, f: F) -> ClientRequest where
    F: FnOnce(&mut ClientRequest), 

This method calls provided closure with builder reference if value is true.

pub fn if_some<T, F>(self, value: Option<T>, f: F) -> ClientRequest where
    F: FnOnce(T, &mut ClientRequest), 

This method calls provided closure with builder reference if value is Some.

pub fn send_body<B>(
    self,
    body: B
) -> impl Future<Item = ClientResponse<impl Stream<Item = Bytes, Error = PayloadError>>, Error = SendRequestError> where
    B: Into<Body>, 

Complete request construction and send body.

pub fn send_json<T>(
    self,
    value: &T
) -> impl Future<Item = ClientResponse<impl Stream<Item = Bytes, Error = PayloadError>>, Error = SendRequestError> where
    T: Serialize, 

Set a JSON body and generate ClientRequest

pub fn send_form<T>(
    self,
    value: &T
) -> impl Future<Item = ClientResponse<impl Stream<Item = Bytes, Error = PayloadError>>, Error = SendRequestError> where
    T: Serialize, 

Set a urlencoded body and generate ClientRequest

ClientRequestBuilder can not be used after this call.

pub fn send_stream<S, E>(
    self,
    stream: S
) -> impl Future<Item = ClientResponse<impl Stream<Item = Bytes, Error = PayloadError>>, Error = SendRequestError> where
    E: Into<Error> + 'static,
    S: Stream<Item = Bytes, Error = E> + 'static, 

Set an streaming body and generate ClientRequest.

pub fn send(
    self
) -> impl Future<Item = ClientResponse<impl Stream<Item = Bytes, Error = PayloadError>>, Error = SendRequestError>

Set an empty body and generate ClientRequest.
