Struct Redirect

pub struct Redirect { /* private fields */ }

A middleware which attempts to follow HTTP redirects.

Implementations

impl Redirect

pub fn new(attempts: u8) -> Self

Create a new instance of the Redirect middleware, which attempts to follow redirects up to as many times as specified.

Consider using Redirect::default() for the default number of redirect attempts.

This middleware will follow redirects from the Location header if the server returns any of the following http response codes:

• 301 Moved Permanently
• 302 Found
• 303 See other
• 307 Temporary Redirect
• 308 Permanent Redirect

Errors

An error will be passed through the middleware stack if the value of the Location header is not a validly parsing url.

Caveats

This will presently make at least one additional HTTP request before the actual request to determine if there is a redirect that should be followed, so as to preserve any request body.

Examples

caps.http
    .get("https://httpbin.org/redirect/2")
    .middleware(crux_http::middleware::Redirect::default())
    .send(Event::ReceiveResponse)

Trait Implementations

impl Middleware for Redirect

fn handle<'life0, 'life1, 'async_trait>( &'life0 self, req: Request, client: Client, next: Next<'life1>, ) -> Pin<Box<dyn Future<Output = Result<ResponseAsync>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,
