Function query_params 

pub fn query_params<B>(req: &Request<B>) -> &QueryParams

Read the request’s query parameters, treating a request with no query string as one with no parameters.

Always returns a map: a request whose query string was absent, empty, or unparseable is indistinguishable here from one that carried ? and nothing else.

Example

use mini_serve::query_params;

let page = query_params(&req).0.get("page").cloned();
