winsock程序之--字符串的发送与接收

1、服务器端程序

功能：接收客户端发来的字符串，并把字符串原封不动地发送给客户端

#include <stdio.h>#include <WinSock2.h>#include "mystr.h"#include "mysock.h"#pragma comment(lib, "ws2_32")int main() {    int iResult;    WORD wVersionRequested;    WSADATA wsaData;    SOCKET listenSocket;    SOCKET acceptSocket;    struct sockaddr_in service;    char received[256];    /*    initialize winsock...    create sock...    bind...    listen...    accept...    */    /* read data and send it */    memset(received, 0, sizeof(received));    readString(acceptSocket, received, sizeof(received));    while (strLen(received) > 0 && strCmp(received, "quit") != 0) {        printf("received: %s\n", received);        writeString(acceptSocket, received);        memset(received, 0, sizeof(received));        readString(acceptSocket, received, sizeof(received));    }    printf("bye-bye!\n");    closesocket(listenSocket);    WSACleanup();    return 0;}

2、客户端程序

功能：将输入的字符串发送给服务器端，并接收和打印服务器端发来字符串

#include <stdio.h>#include <WinSock2.h>#include "mystr.h"#include "mysock.h"#pragma comment(lib, "ws2_32")int main() {    int iResult;    WORD wVersionRequested;    WSADATA wsaData;    SOCKET clientSocket;    struct sockaddr_in clientService;    char sent[256];    char received[256];    /*    initialize winsock...    create sock...    connect...    */    /* write data and receive it */    memset(sent, 0, sizeof(sent));    printf("> ");    gets_s(sent, sizeof(sent) - 1);    while (strCmp(sent, "quit") != 0) {        writeString(clientSocket, sent);        memset(received, 0, sizeof(received));        readString(clientSocket, received, sizeof(received));        printf("received: %s\n", received);        printf("> ");        gets_s(sent, sizeof(sent) - 1);    }    printf("bye-bye");    closesocket(clientSocket);    WSACleanup();    return 0;}

运行结果如下：
