用C语言爬网页代码

今天下午把爬代码看了一下，也敲了，只不过我爬下来的总是乱码，现在大多数爬虫都是Python和Java，很少有人用C语言爬了；

#include <stdio.h>#include <winsock2.h>#include<string.h>#pragma comment(lib, "ws2_32.lib")int main(){WSADATA  wd; // web APISOCKET c;char sendBuf[1000]="",recvBuf[1000]="";  // 创建字符数组 SOCKADDR_IN saddr;if(WSAStartup(MAKEWORD(2,2),&wd)!=0){printf("初始化失败\n");return 0;}if(HIBYTE(wd.wVersion)!=2||LOBYTE(wd.wVersion)!=2){        printf("初始化失败\n");WSACleanup();return 1;}c=socket(AF_INET,SOCK_STREAM,0);  //创建客户端    saddr.sin_addr.S_un.S_addr = inet_addr("119.75.217.56");//百度ip    saddr.sin_family=AF_INET;saddr.sin_port=htons(80);       /* 连接服务器*/if(connect(c, (SOCKADDR*)&saddr, sizeof(SOCKADDR))!=0){printf("connect failed\n");return 1;}     strnset(sendBuf,0,1024);     //请求百度网页 strcat(sendBuf,"GET /index.php HTTP/1.0\r\n"); strcat(sendBuf,"host:www.baidu.com\r\n\r\n"); send(c,sendBuf,strlen(sendBuf)+1,0);  strnset(recvBuf,0,1024); while(recv(c,recvBuf,1024,0)) { puts(recvBuf); strnset(recvBuf,0,1024); }      closesocket(c); return 0;}
