pub struct Response { /* private fields */ }
Expand description
A Response to a submitted Request
.
Implementations§
source§impl Response
impl Response
sourcepub fn url(&self) -> &Url
pub fn url(&self) -> &Url
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");
sourcepub fn status(&self) -> StatusCode
pub fn status(&self) -> StatusCode
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),
};
sourcepub fn headers(&self) -> &HeaderMap
pub fn headers(&self) -> &HeaderMap
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)?;
}
}
}
sourcepub fn json<T: DeserializeOwned>(&mut self) -> Result<T>
pub fn json<T: DeserializeOwned>(&mut self) -> Result<T>
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
sourcepub fn text(&mut self) -> Result<String>
pub fn text(&mut self) -> Result<String>
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.
sourcepub fn copy_to<W: ?Sized>(&mut self, w: &mut W) -> Result<u64>where
W: Write,
pub fn copy_to<W: ?Sized>(&mut self, w: &mut W) -> Result<u64>where
W: Write,
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());
sourcepub fn error_for_status(self) -> Result<Self>
pub fn error_for_status(self) -> Result<Self>
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));
}
