[转]windows和linux进行socket通信

     在公司里面,我们平时使用的机器一般都是windows系统,但是开发、编译的机器往往是linux服务器。通过ping、ftp、samba、 telnet、ssh,人们可以很方便与服务器连接。windows系统使用的是windows socket,而linux使用的posix socket,那么这两个socket之间是怎么通信的呢?网上关于windows与windows通信的代码很多,linux与linux通信的代码也 很多,但是windows和linux通信的代码很少。这里,我就想写一个简单的socket代码,实现linux和windows的通信。

 

    其实,广义一点看,网页访问、邮箱、游戏、聊天工具都是利用socket实现的,当然后面实现的逻辑要比我们写的代码复杂的多。但是,我们完全可以利用简 单的代码来说明socket通信问题,能做到这一点就足够了。这也是我一直推崇的方法,用最简单的代码表达最实际的功能。

 

    windows侧的client代码,

 

#include <stdio.h>
#include <Windows.h>
 
#pragma comment(lib,"ws2_32.lib")
#define  PORT 4000
#define  IP_ADDRESS "192.168.1.102"
 
int main(int argc, char* argv[])
{
    WSADATA  Ws;
    SOCKET ClientSocket;
    struct sockaddr_in ClientAddr;
    int Ret = 0;
    char SendBuffer[MAX_PATH];

    /* Init Windows Socket */
    if ( WSAStartup(MAKEWORD(2,2), &Ws) != 0 )
    {
        printf("Init Windows Socket Failed::%d\n", GetLastError());
        return -1;
    }
 
    /* Create Socket */
    ClientSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if ( ClientSocket == INVALID_SOCKET )
    {
        printf("Create Socket Failed::%d\n", GetLastError());
        return -1;
    }

    ClientAddr.sin_family = AF_INET;
    ClientAddr.sin_addr.s_addr = inet_addr(IP_ADDRESS);
    ClientAddr.sin_port = htons(PORT);
    memset(ClientAddr.sin_zero, 0x00, 8);

	/* connect socket */
    Ret = connect(ClientSocket,(struct sockaddr*)&ClientAddr, sizeof(ClientAddr));
    if ( Ret == SOCKET_ERROR )
    {
        printf("Connect Error::%d\n", GetLastError());
        return -1;
    }
    else
    {
        printf("Connect succedded!\n");
    }

    while (1)
    {
        scanf("%s", SendBuffer);

		/* send data to server */
        Ret = send(ClientSocket, SendBuffer, (int)strlen(SendBuffer), 0);
        if ( Ret == SOCKET_ERROR )
        {
            printf("Send Info Error::%d\n", GetLastError());
            break;
        }
		
		if('q' == SendBuffer[0])
		{
			break;
		}
    }
    
	/* close socket */
    closesocket(ClientSocket);
    WSACleanup();
 
    return 0;
 }
 


    linux侧的server代码,

 

 

#include <netinet/in.h>    
#include <sys/types.h>    
#include <sys/socket.h>    
#include <stdio.h>        
#include <stdlib.h>       
#include <string.h>       

#define HELLO_WORLD_SERVER_PORT    4000
#define LENGTH_OF_LISTEN_QUEUE 20
#define BUFFER_SIZE 1024

int main(int argc, char **argv)
{
    struct sockaddr_in server_addr;
	int server_socket;
	int opt = 1;
   
    bzero(&server_addr,sizeof(server_addr)); 
	
    server_addr.sin_family = AF_INET;
    server_addr.sin_addr.s_addr = htons(INADDR_ANY);
    server_addr.sin_port = htons(HELLO_WORLD_SERVER_PORT);

	/* create a socket */
    server_socket = socket(PF_INET,SOCK_STREAM,0);
    if( server_socket < 0)
    {
        printf("Create Socket Failed!");
        exit(1);
    }
 
    /* bind socket to a specified address*/
    setsockopt(server_socket, SOL_SOCKET, SO_REUSEADDR, &opt, sizeof(opt));
    if( bind(server_socket,(struct sockaddr*)&server_addr,sizeof(server_addr)))
    {
        printf("Server Bind Port : %d Failed!", HELLO_WORLD_SERVER_PORT); 
        exit(1);
    }

    /* listen a socket */
    if(listen(server_socket, LENGTH_OF_LISTEN_QUEUE))
    {
        printf("Server Listen Failed!"); 
        exit(1);
    }
	
	/* run server */
    while (1) 
    {
        struct sockaddr_in client_addr;
		int client_socket;		
        socklen_t length;
		char buffer[BUFFER_SIZE];

		/* accept socket from client */
		length = sizeof(client_addr);
        client_socket = accept(server_socket, (struct sockaddr*)&client_addr, &length);
        if( client_socket < 0)
        {
            printf("Server Accept Failed!\n");
            break;
        }
        
		/* receive data from client */
		while(1)
		{
			bzero(buffer, BUFFER_SIZE);
			length = recv(client_socket, buffer, BUFFER_SIZE, 0);
			if (length < 0)
			{
				printf("Server Recieve Data Failed!\n");
				break;
			}
			
			if('q' == buffer[0])
			{
				printf("Quit from client!\n");
				break;
			}
			
			printf("%s\n", buffer);
		}	
		
        close(client_socket);
    }
	
    close(server_socket);
    return 0;
}


    windows侧的代码使用vc6.0编译就可以,而linux侧的代码用gcc就ok了,即gcc server.c -o server。首先,在linux侧输入./server,然后打开widnows侧的client程序,然后在windows侧的每一个字符输入都会在 linux打印出来。如果想退出,输入q即可。但是此时server不会退出,它在等待下一个client的通信,继续服务于大家,就是这么简单。

 

    这里的server和client代码是根据网友的代码修改而来,一并表示感谢。如有侵权,请邮件告知。
