async fn protected_route(AuthUser(user): AuthUser) -> impl IntoResponse { format!("Hello, {}! Your scopes are: {:?}", user.username, user.scope) } 这个路由只有在用户通过认证后才能访问。 要点: - 使用 FromRequestParts trait 可以方便
use axum::{ async_trait, extract::FromRequestParts, routing::get, Router, }; use regex::Regex; struct RegexParam(String); #[async_trait] impl<S> FromRequestParts<S> for RegexParam where S: Send + Sync, { type Rejection = (); async fn from_request_parts(parts: &mut Parts, _state...

现在,我们要实现自己的 Json extractor——当然,为了避免混乱,建议取别的名字,比如MyJson等。 // src/extract.rs// 定义自己的Json extractpubstructJson<T>(pubT);// 实现FromRequest#[async_trait]impl<B, T> FromRequest<B>forJson<T>whereB: axum::body::HttpBody +Send, T: DeserializeOwned, B::...

async fn handler3() -> Html<&'static str> { Html(include_str!("templates/index.html")) } 如果只是返回静态的内容,那就太无趣了,所以一般会结合模板引擎使用。 use axum::{ routing::get, Router, extract::Path, response::{Html, IntoResponse, Response}, ...
