本文介绍了我如何在C中解析Html代码，这是一个例外的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
#include<conio.h>
#include <stdio.h>
#include <stdlib.h>
#include<winsock2.h>
#pragma comment(lib,"ws2_32.lib") //Winsock Library
int main(int argc , char *argv[])
{
char *ptr;
char *token = NULL;
char *aa = "<head>";
//ptr=(char*)malloc(30000*sizeof(aa));
WSADATA wsa;

struct sockaddr_in server;
char *message , server_reply[30000];
int recv_size;

return 1;
}
printf("Initialised.\n");
//Create a socket
if((s = socket(AF_INET , SOCK_STREAM , 0 )) == INVALID_SOCKET)

}
printf("Socket created.\n");
server.sin_addr.s_addr = inet_addr("ip address" );
server.sin_family = AF_INET;
server.sin_port = htons( 80 );
//Connect to remote server
if (connect(s , (struct sockaddr *)&server , sizeof(server)) < 0)
{
puts("connect error");
getch();
return 1;
}
puts("Connected");
//Send some data
message ="GET / HTTP/1.1\r\nHost: www.....com\r\nConnection: close\r\n\r\n' | ncwww.......com 80 ";
if( send(s , message , strlen(message) , 0) < 0)
{
puts("Send failed");
return 1;
}
puts("Data Send\n");
//Receive a reply from the server
if((recv_size = recv(s , server_reply , 20835, 0)) == SOCKET_ERROR)
{
puts("recv failed");
}
puts("Reply received\n");
//Add a NULL terminating character to make it a proper string before printing
server_reply[recv_size] = '\0';
//puts(server_reply);
token = strtok(server_reply, "\n");
while (token) {
token = strtok(NULL, "\n");
if(strstr(token,aa) !=NULL)
{
printf("%s",token);
}
}
getch();
return 0;
}推荐答案
while (token) {
token = strtok(NULL, "\n");
// Break when no more new line characters
if (NULL == token)
break;
if(strstr(token,aa) !=NULL)
{
printf("%s",token);
}
}
