用c语言实现https通信,C/C++实现HTTPS通信

#include "afxinet.h"

CInternetSession mysession;

CHttpConnection *myconn;

CString VoidText;

CString strSentence, strGetSentence;

int _my;

CString Call_Url = "www.zc91.cn";

INTERNET_PORT nPort;

DWORD dwServiceType;

CString strServerName;

CString str ;

DWORD _dwStatus, _dwStatusLen;

CString _Url, _UrlHttp = "https://";

_Url.Format("%s%s", _UrlHttp, Call_Url);//这里拼成的字符串是"https://www.zc91.cn/"

BOOL _GetParse = AfxParseURL(_Url, dwServiceType, strServerName, str , nPort);//调用解析URL方法，自动得到端口号

BOOL _session = mysession.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, 1000 * 20); //设置连接超时20秒

_session = mysession.EnableStatusCallback(TRUE);

myconn = mysession.GetHttpConnection(Call_Url, INTERNET_FLAG_SECURE, nPort, NULL, NULL);//连接https服务器
