【Rust】单线程服务器
环境
- Rust 1.56.1
- VSCode 1.61.2
概念
参考：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>
总结
使用 rust 实现了一个单线程的 web 服务器。
