Android客户端与本地服务器Socket通信需要注意的是，Android应用Socket通信时，有几点要求必须得遵守： 1. andriod客户端添加网络访问权限 2.socket操作不能放在UI线程中进行 3.指定正确的IP地址和端口号阅读详情

#include <winsock.h>

#include <stdio.h>



#define MY_PORT 6000



int main() {

	SOCKET conn_sock;

	struct sockaddr_in remote_addr;

	int bytes_recvd;

	char buffer[100];

	WSADATA wsaData;

	

	WSAStartup(MAKEWORD(1,1),&wsaData);



	conn_sock = socket(AF_INET, SOCK_STREAM, 0); //socket构造函数

    bind(conn_sock, (struct sockaddr *)&remote_addr, sizeof(struct sockaddr));//绑定



	remote_addr.sin_family = AF_INET;

	remote_addr.sin_addr.s_addr = inet_addr("localhost");

    

	connect(conn_sock, (struct sockaddr *)&remote_addr, sizeof(struct sockaddr));//建立连接

	bytes_recvd = recv(conn_sock, buffer, sizeof(buffer), 0);	//接收数据
