使用套接字在Android设备上创建点击从python转换为C

编程问答 2022-11-14

问题描述

我正在尝试创建一个与客户端android设备通信以模拟其点击的套接字程序，到目前为止，我设法使用以下代码在Python上成功设置并运行了TCP服务器代码。

import socket
import time
 
HOST = '192.168.1.243'
PORT = 4000
 
with socket.socket(socket.AF_INET,socket.SOCK_STREAM) as s:
   s.bind((HOST,PORT))
   s.listen()
   conn,addr = s.accept()
   while True:
       time.sleep(1)
       conn.sendall(b'a 925 1725\n')  //Click 1
       time.sleep(1)
       conn.sendall(b'a 220 2100\n')  //Click 2

经过研究，我能够为TCP服务器生成C代码以绑定主机和端口，侦听客户端并接受客户端。

            struct sockaddr_in server;//Declare structure to connect to a remote server
                int opt = 1;
                int addrlen = sizeof(server);
                char buffer[1024] = {0};

                if (createsocket == -1){                                                                                                      
                printf("Error creating socket");                                                                                  
                }
                                                                                                                                         
                 //Assign structure                                                                                                      
                 server.sin_family = AF_INET;
                 server.sin_addr.s_addr = inet_addr("10.10.10.10"); //Assign host
                 server.sin_port = htons( PORT ); //Assign port

                 //Bind host and phone
                 if (bind(createsocket,(struct sockaddr *)&server,sizeof(server))<0){
                        printf("Bind error\n");
                        return 1;
                        }
                else
                        printf("Bind Connected\n");

                //Ready to receive connections                                                                                          
                 if (listen(createsocket,5) < 0){
                        printf("Listening error\n");
                        return 1;
                        }
                else
                        printf("Listening\n");

                //Connection received,pending accept
            if((phone_socket = accept(createsocket,(socklen_t*)&addrlen)< 0){
                     printf("Failed to accept\n");
                     return 1;
                     }
                 else
                     printf("Accepted device\n");

                  while(1){
                     sleep(1);  //One second delay
                     printf("click\n");  //Supposed click command
                     }
}

有人知道如何将用于单击的python行conn.sendall(b'a 925 1725\n')转换为C吗？

谢谢您的帮助！
