我嘗試在我的 Android 應(yīng)用程序中使用 Sockets，但遇到了一個(gè)小問題。我使用 python 創(chuàng)建服務(wù)器，一切正常。服務(wù)器收到來自Android客戶端的消息，但似乎無法在客戶端上獲得響應(yīng)。這是我的服務(wù)器端：import socketHOST = '10.10.0.153'PORT = 7800s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)print('socket created')try:    s.bind((HOST, PORT))except socket.error as err:    print('binding faild')s.listen(10)while 1:    conn, addr = s.accept()    print('Connect with ' + addr[0] + ':' + str(addr[1]))    buf = conn.recv(1024)    print(buf)    data = "hello"    conn.send(data.encode('utf-8'))s.close()這是客戶端：public class Sender extends AsyncTask<String, Void, Void> {    private final String TAG = "Sender";    Socket s;    PrintWriter pw;    @Override    protected Void doInBackground(String... strings) {    String message = strings[0];    try {        s = new Socket(GlobalVars.SERVER, GlobalVars.PORT);        pw = new PrintWriter(s.getOutputStream());        pw.write(message);        pw.flush();        BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));        String msg = in.readLine();        System.out.println(msg);        pw.close();        s.close();    } catch(IOException e) {        e.printStackTrace();    }}
