[−][src]Struct surf::RequestBuilder

pub struct RequestBuilder { /* fields omitted */ }

Response Builder

Provides an ergonomic way to chain the creation of a response. This is generally accessed through surf::{method}(), however Request::builder is also provided.

Examples

let mut request = surf::post("https://httpbin.org/post")
    .body("<html>hi</html>")
    .header("custom-header", "value")
    .content_type(http::mime::HTML)
    .build();

assert_eq!(request.take_body().into_string().await.unwrap(), "<html>hi</html>");
assert_eq!(request.method(), http::Method::Post);
assert_eq!(request.url(), &Url::parse("https://httpbin.org/post")?);
assert_eq!(request["custom-header"], "value");
assert_eq!(request["content-type"], "text/html;charset=utf-8");
let url = Url::parse("https://httpbin.org/post")?;
let request = Request::builder(http::Method::Post, url).build();

Implementations

impl RequestBuilder[src]

pub fn new(method: Method, url: Url) -> Self[src]

Create a new instance.

This method is particularly useful when input URLs might be passed by third parties, and you don't want to panic if they're malformed. If URLs are statically encoded, it might be easier to use one of the shorthand methods instead.

Examples

use surf::http::Method;
use surf::url::Url;

let method = Method::Get;
let url = Url::parse("https://httpbin.org/get")?;
let req = surf::RequestBuilder::new(Method::Get, url).build();

pub fn header(
    self,
    key: impl Into<HeaderName>,
    value: impl ToHeaderValues
) -> Self[src]

Sets a header on the request.

let req = surf::get("https://httpbin.org/get").header("header-name", "header-value").build();
assert_eq!(req["header-name"], "header-value");

pub fn content_type(self, content_type: impl Into<Mime>) -> Self[src]

Sets the Content-Type header on the request.

let req = surf::post("https://httpbin.org/post").content_type(mime::HTML).build();
assert_eq!(req["content-type"], "text/html;charset=utf-8");

pub fn body(self, body: impl Into<Body>) -> Self[src]

Sets the body of the request.

use serde_json::json;
let mut req = surf::post("https://httpbin.org/post").body(json!({ "any": "Into<Body>"})).build();
assert_eq!(req.take_body().into_string().await.unwrap(), "{\"any\":\"Into<Body>\"}");

pub async fn recv_bytes(self) -> Result<Vec<u8>>[src]

Submit the request and get the response body as bytes.

Examples

let bytes = surf::get("https://httpbin.org/get").recv_bytes().await?;
assert!(bytes.len() > 0);

pub async fn recv_string(self) -> Result<String>[src]

Submit the request and get the response body as a string.

Examples

let string = surf::get("https://httpbin.org/get").recv_string().await?;
assert!(string.len() > 0);

pub async fn recv_json<T: DeserializeOwned>(self) -> Result<T>[src]

Submit the request and decode the response body from json into a struct.

Examples

#[derive(Deserialize, Serialize)]
struct Ip {
    ip: String
}

let uri = "https://api.ipify.org?format=json";
let Ip { ip } = surf::get(uri).recv_json().await?;
assert!(ip.len() > 10);

pub async fn recv_form<T: DeserializeOwned>(self) -> Result<T>[src]

Submit the request and decode the response body from form encoding into a struct.

Errors

Any I/O error encountered while reading the body is immediately returned as an Err.

If the body cannot be interpreted as valid json for the target type T, an Err is returned.

Examples

#[derive(Deserialize, Serialize)]
struct Body {
    apples: u32
}

let url = "https://api.example.com/v1/response";
let Body { apples } = surf::get(url).recv_form().await?;

pub fn build(self) -> Request[src]

Return the constructed Request.

pub fn send(self) -> BoxFuture<'static, Result<Response>>[src]

Create a Client and send the constructed Request from it.
