C++实现申请帐号---发送post提交表单信息包

测试网址为:http://www.exam8.com/

测试网址ip:222.73.24.32

测试帐号:lzh_5

密码:123456789


首先要确定提交表单的信息,我用抓包工具抓了post的包,然后写程序模拟发送过程,实现了登录过程。


注意事项:

1.一定要按照抓包的信息发送,甚至空格、换行数都要一样;

2.模拟登录的网页没有验证码;


代码:

//post提交表单申请帐号
#include<stdio.h>
#include<string>
#include<winsock2.h>
#include<windows.h>
#include<iostream>
#include<fstream>
#pragma comment(lib, "ws2_32.lib")

#define max 20480

using namespace std;

int main()
{
	int num,sum;

	SOCKET s;
	WSADATA wsa;
	struct sockaddr_in serv;

	char sndBuf[max], rcvBuf[max];

	WSAStartup(MAKEWORD(2, 1), &wsa);

	if ((s = socket(AF_INET, SOCK_STREAM, 0))<0)
	{
		perror("socket error!");
		exit(1);
	}

	memset(&serv,0,sizeof(serv));
	serv.sin_family = AF_INET;
	serv.sin_port = htons(80);
	//serv.sin_addr.s_addr = *((int*)*host_addr->h_addr_list);
	serv.sin_addr.S_un.S_addr = inet_addr("222.73.24.32");

	if ((connect(s, (struct sockaddr *)&serv, sizeof(serv)))<0)
	{
		perror("connet error!");
		exit(1);
	}

	memset(sndBuf, 0, max);
	memset(rcvBuf, 0, max);

	//头信息
    strcat(sndBuf, "POST ");
    strcat(sndBuf, "/inc/Check.asp HTTP/1.1\r\n");
    strcat(sndBuf, "x-requested-with: XMLHttpRequest\r\n");
	strcat(sndBuf, "Accept-Language: zh-cn\r\n");
    strcat(sndBuf, "Referer: http://reg.exam8.com/");
    strcat(sndBuf, "\r\n");
	strcat(sndBuf, "Accept: */*\r\n");
	strcat(sndBuf, "Content-Type: application/x-www-form-urlencoded\r\n");

	puts(sndBuf);
  
	if ((num = send(s,sndBuf,max, 0))<0)
    {
		perror("send error!");
		exit(1);
	}
	
	puts("send success!\n");

	sum = recv(s, rcvBuf, max-1, 0);//如果rcvBuf的存储空间减小,则分几次copy
	
	if(sum>0)
	{
		puts("OK!"); 
		printf("%s",rcvBuf);
	}
	
	puts("\nread success!\n");
	
	closesocket(s);

	system("pause");
	WSACleanup();
	
	return 0;

}

运行结果:

1.提交给网站的表单信息



2.网页的返回信息



3.申请成功后返回信息



4.在此运行此程序返回信息
