環境
- Rust 1.56.1
- VSCode 1.61.2
概念
參考：https://doc.rust-lang.org/stable/book/ch20-01-single-threaded.html
示例
main.rs
use std::fs; use std::io::Read; use std::io::Write; use std::net::TcpListener; use std::net::TcpStream; fn main() { let listener = TcpListener::bind("127.0.0.1:7878").unwrap(); println!("bind"); for stream in listener.incoming() { let stream = stream.unwrap(); handle_connection(stream); } } fn handle_connection(mut stream: TcpStream) { let mut buffer = [0; 1024]; let length = stream.read(&mut buffer).unwrap(); if length == 0 { println!("EOF"); } let contents = fs::read_to_string("hello.html").unwrap(); let response = format!( "HTTP/1.1 200 OK\r\nContent-Length: {}\r\n\r\n{}", contents.len(), contents ); stream.write_all(response.as_bytes()).unwrap(); stream.flush().unwrap(); }
hello.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Hello!</title>
</head>
<body>
<h1>Hello!</h1>
<p>Hi from Rust</p>
</body>
</html>
總結
使用 rust 實現了一個單執行緒的 web 伺服器。
