HTTP自定义Header-(SOCKET-TCP)

  HTTP自定义Header-TCP

    前几天弄一些东西，需要在发送http请求的时候自定义http头，找了几个库用着很不爽。有的把Cookie直接干掉了，还自己在头里加了版权，最后终于忍不了了。在网上一把梭了一个TCP的，这个比较灵活，没有那么多事，THHP下面终归还是TCP:

一把梭的代码如下：

#include "HttpConnect.h"#ifdef WIN32 #pragma comment(lib,"ws2_32.lib") #endifHttpConnect::HttpConnect() { #ifdef WIN32//此处一定要初始化一下，否则gethostbyname返回一直为空WSADATA wsa = { 0 };WSAStartup(MAKEWORD(2, 2), &wsa); #endif }HttpConnect::~HttpConnect() {} void HttpConnect::socketHttp(std::string host, std::string request) {int sockfd;struct sockaddr_in address;struct hostent *server;sockfd = socket(AF_INET,SOCK_STREAM,0);address.sin_family = AF_INET;address.sin_port = htons(80);server = gethostbyname(host.c_str());memcpy((char *)&address.sin_addr.s_addr,(char*)server->h_addr, server->h_length);if(-1 == connect(sockfd,(struct sockaddr *)&address,sizeof(address))){DBG <<"connection error!"<<std::endl;return;}DBG << request << std::endl; #ifdef WIN32send(sockfd, request.c_str(),request.size(),0); #elsewrite(sockfd,request.c_str(),request.size()); #endifchar buf[1024*1024] = {0};int offset = 0;int rc;#ifdef WIN32while(rc = recv(sockfd, buf+offset, 1024,0)) #elsewhile(rc = read(sockfd, buf+offset, 1024)) #endif{offset += rc;}#ifdef WIN32closesocket(sockfd); #elseclose(sockfd); #endifbuf[offset] = 0;DBG << buf << std::endl;}void HttpConnect::postData(std::string host, std::string path, std::string post_content) {//POST请求方式std::stringstream stream;stream << "POST " << path;stream << " HTTP/1.0\r\n";stream << "Host: "<< host << "\r\n";stream << "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3\r\n";stream << "Content-Type:application/x-www-form-urlencoded\r\n";stream << "Content-Length:" << post_content.length()<<"\r\n";stream << "Connection:close\r\n\r\n";stream << post_content.c_str();socketHttp(host, stream.str()); }void HttpConnect::getData(std::string host, std::string path, std::string get_content) {//GET请求方式std::stringstream stream;stream << "GET " << path << "?" << get_content;stream << " HTTP/1.0\r\n";stream << "Host: " << host << "\r\n";stream <<"User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3\r\n";stream <<"Connection:close\r\n\r\n";socketHttp(host, stream.str()); }调用方法：HttpConnect *http = new HttpConnect();http->getData("127.0.0.1", "/login", "id=liukang&pw=123");http->postData("127.0.0.1", "/login","id=liukang&pw=123");     当时用的是GET 自动以Header，就顺便改了下，代码如下。用的时候可以根据实际情况，改改上面代码就行了。TCP的话在C++里控制Header就比较方便了。
