std::net::TcpStream的增强版

tcp-stream是一个库，旨在为std::net::TcpStream提供TLS支持

关于rustls加密后端的警告

必须使用功能标志在rustls中启用加密实现。我们模仿rustls的行为，为每个实现提供一个功能标志，默认情况下与rustls相同。可用的选项有

• rustls--aws_lc_rs (默认)
• rustls--ring

示例

连接到远程服务器

use tcp_stream::{HandshakeError, TcpStream, TLSConfig};

use std::io::{self, Read, Write};

fn main() {
    let stream = TcpStream::connect("google.com:443").unwrap();
    let mut stream = stream.into_tls("google.com", TLSConfig::default());

    while let Err(HandshakeError::WouldBlock(mid_handshake)) = stream {
        stream = mid_handshake.handshake();
    }

    let mut stream = stream.unwrap();

    while let Err(err) = stream.write_all(b"GET / HTTP/1.0\r\n\r\n") {
        if err.kind() != io::ErrorKind::WouldBlock {
            panic!("error: {:?}", err);
        }
    }
    stream.flush().unwrap();
    let mut res = vec![];
    while let Err(err) = stream.read_to_end(&mut res) {
        if err.kind() != io::ErrorKind::WouldBlock {
            panic!("stream error: {:?}", err);
        }
    }
    println!("{}", String::from_utf8_lossy(&res));
}
