Lib.rs

一个简单的 Http 服务器库。

基本的 GET 请求

use chuchi::{get, Res};

struct GlobalName(String);

// handle a simple get request
#[get("/")]
fn root(global_name: Res<GlobalName>) -> String {
	format!("Hi, this is {}", global_name.0)
}

#[tokio::main]
async fn main() {
	let mut server = chuchi::build("0.0.0.0:3000").await
		.expect("Failed to parse address");

	server.add_resource(GlobalName("fire".into()));
	server.add_route(root);

	server.run().await.unwrap();
}

更多示例请查看 examples 目录和测试目录。

功能

• json
• fs
• http2 (启用 http 2 支持)
• ws (添加 WebSocket 支持)
• trace
