[][src]Struct reqwest::Response

pub struct Response { /* fields omitted */ }

A Response to a submitted Request.

Methods

impl Response
[src]

Get the final Url of this Response.

Example

let resp = reqwest::get("http://httpbin.org/redirect/1")?;
assert_eq!(resp.url().as_str(), "http://httpbin.org/get");

Get the remote address used to get this Response.

Example

let resp = reqwest::get("http://httpbin.org/redirect/1")?;
println!("httpbin.org address: {:?}", resp.remote_addr());

Get the StatusCode of this Response.

Examples

let resp = reqwest::get("http://httpbin.org/get")?;
if resp.status().is_success() {
    println!("success!");
} else if resp.status().is_server_error() {
    println!("server error!");
} else {
    println!("Something else happened. Status: {:?}", resp.status());
}
use reqwest::Client;
use reqwest::StatusCode;
let client = Client::new();
let resp = client.post("http://httpbin.org/post")
            .body("possibly too large")
            .send()?;
match resp.status() {
    StatusCode::OK => println!("success!"),
    StatusCode::PAYLOAD_TOO_LARGE => {
        println!("Request payload is too large!");
    }
    s => println!("Received response status: {:?}", s),
};

Get the Headers of this Response.

Example

Checking the Content-Length header before reading the response body.

let client = Client::new();
let mut resp = client.head("http://httpbin.org/bytes/3000").send()?;
if resp.status().is_success() {
    let len = resp.headers().get(CONTENT_LENGTH)
                .and_then(|ct_len| ct_len.to_str().ok())
                .and_then(|ct_len| ct_len.parse().ok())
                .unwrap_or(0);
    // limit 1mb response
    if len <= 1_000_000 {
        let mut buf = Vec::with_capacity(len as usize);
        let mut resp = reqwest::get("http://httpbin.org/bytes/3000")?;
        if resp.status().is_success() {
            ::std::io::copy(&mut resp, &mut buf)?;
        }
    }
}

Get the HTTP Version of this Response.

Try and deserialize the response body as JSON using serde.

Examples

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

let json: Ip = reqwest::get("http://httpbin.org/ip")?.json()?;

Errors

This method fails whenever the response body is not in JSON format or it cannot be properly deserialized to target type T. For more details please see [serde_json::from_reader]. [serde_json::from_reader]: https://docs.serde.rs/serde_json/fn.from_reader.html

Get the response text.

This method decodes the response body with BOM sniffing and with malformed sequences replaced with the REPLACEMENT CHARACTER. Encoding is determinated from the charset parameter of Content-Type header, and defaults to utf-8 if not presented.

Example

let content = reqwest::get("http://httpbin.org/range/26")?.text()?;

Note

This consumes the body. Trying to read more, or use of response.json() will return empty values.

Copy the response body into a writer.

This function internally uses [std::io::copy] and hence will continuously read data from the body and then write it into writer in a streaming fashion until EOF is met.

On success, the total number of bytes that were copied to writer is returned. [std::io::copy]: https://doc.rust-lang.org/std/io/fn.copy.html

Example

let mut resp = reqwest::get("http://httpbin.org/range/5")?;
let mut buf: Vec<u8> = vec![];
resp.copy_to(&mut buf)?;
assert_eq!(b"abcde", buf.as_slice());

Turn a response into an error if the server returned an error.

Example

let res = reqwest::get("http://httpbin.org/status/400")?
    .error_for_status();
if let Err(err) = res {
    assert_eq!(err.status(), Some(reqwest::StatusCode::BAD_REQUEST));
}
