如何从Android Studio中的Python插座服务器接收输入？

Question

我有一个 python 套接字服务器，它从 Android 应用程序接收一个字符串，并且应该返回相同的大写字符串。应用程序可以发送字符串，我在服务器中接收它，但是我如何在 Android studio 中接收返回的字符串？

这是我的Python代码：

import socket

HOST = "127.0.0.1"  # Standard loopback interface address (localhost)
PORT = 65432  # Port to listen on (non-privileged ports are > 1023)

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.bind((HOST, PORT))
s.listen()
conn, addr = s.accept()
with conn:
    print(f"Connected by {addr}")
    while True:
        data = conn.recv(1024)
        print(data)
        if not data:
            break
        conn.sendall(data.upper())

这是我的发送消息函数

Socket s;
PrintWriter pw;

@Override
protected Void doInBackground(String... voids) {
    String message = voids[0];

    byte[] messageByte = new byte[1000];
    boolean end = false;
    String dataString = "";

    try {
        s = new Socket("10.0.2.2", Integer.parseInt("65432"));
        //sending data
        pw = new PrintWriter(s.getOutputStream());
        pw.write(message);
        pw.flush();
        pw.close();
        //////////
        //receiving data


        s.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
