Question

我正在制作一个android应用程序，通过它可以控制我的PC操作（如关机，重新启动和播放音乐）。

但这显示了异常。

2019-07-02 01：24：30.570 31431-9027 / com.sundram.myapplication W / System.err：java.net.ConnectException：无法从/：连接到/192.168.56.1（端口1024）（端口49405）：连接失败：ETIMEDOUT（连接超时）

我尝试了很多关于StackOverflow的答案，但是都没有帮助。

This My Client.java

public class Client extends AsyncTask<Void, Void, Void> {

    String ip_address = "192.168.56.1";
    String type = "";

    Client(String t) {
        type = t;
    }

    @Override
    protected Void doInBackground(Void... voids) {
        if (type == "shutDown") {
            try {
                Socket myScket = new Socket(ip_address, 1024); //getting error in this line 
                OutputStream output = myScket.getOutputStream();
                DataOutputStream opData = new DataOutputStream(output);
                opData.writeBytes("shutDown");
            } catch (IOException e) {
                e.printStackTrace();
            }

        } else if (type == "restart") {
            try {
                Socket myScket = new Socket(ip_address, 1024);
                OutputStream output = myScket.getOutputStream();
                DataOutputStream opData = new DataOutputStream(output);
                opData.writeBytes("restart");
            } catch (IOException e) {
                e.printStackTrace();
            }

        }
        return null;
    }

}

这是我的服务器。py

from socket import *
import os
import platform

host ="192.168.56.1"
port=1024

s=socket(AF_INET,SOCK_STREAM)

s.bind((host,port))

s.listen(5)
while True:
    c,addr = s.accept()

    #print(c.recv(1024).decode('utf-8'))    

    type = c.recv(1024).decode('utf-8')

    if(type == "shutDown"):
        if(platform.system() == "Windows"):
            os.system("shutDown")
        elif(platform.system() == "Linux"):
            os.system("shutDown")
    elif(type == "restart"):
        if(platform.system() == "Windows"):
            os.system("shutDown /r")
        elif(platform.system() == "Linux"):
            os.system("shutDown -r")
    elif(type == "music"):
        if(platform.system() == "Windows"):
            os.system("K:\\1.mp3")
        elif(platform.system() == "Linux"):
            os.system("~/1.mp3")
    #s.close()

此例外
