Function proxy_to_and_forward_response 

pub async fn proxy_to_and_forward_response(
    proxy_address: String,
    base_path: String,
    uri: FullPath,
    params: QueryParameters,
    method: Method,
    headers: HeaderMap,
    body: Bytes,
) -> Result<Response, Rejection>

Build a request and send to the requested address.

Wraps the response into a warp::reply compatible type (http::Response)

Arguments

• proxy_address - A string containing the base proxy address where the request will be forwarded to.

• base_path - A string with the prepended sub-path to be stripped from the request uri path.

• uri -> The uri of the extracted request.

• params -> The URL query parameters

• method -> The request method.

• headers -> The request headers.

• body -> The request body.

Examples

Notice that this method usually need to be used in aggregation with the extract_request_data_filter filter which already provides the (Uri, QueryParameters, Method, Headers, Body) needed for calling this method. But the proxy_address and the base_path arguments need to be provided too.

use warp::{Filter, Reply, Rejection, reply::Response};
use warp_reverse_proxy::{extract_request_data_filter, proxy_to_and_forward_response};

async fn log_response(response: Response) -> Result<impl Reply, Rejection> {
    println!("{:?}", response);
    Ok(response)
}

let request_filter = extract_request_data_filter();
let app = warp::path!("hello" / String)
    .map(|port| (format!("http://127.0.0.1:{}/", port), "".to_string()))
    .untuple_one()
    .and(request_filter)
    .and_then(proxy_to_and_forward_response)
    .and_then(log_response);
