Connecting through Http or Https for CE/Windows Mobile c++/vc++方法一

一：头文件

#include <altcecrt.h>
#include <Wininet.h>
#include "Afxinet.h"
#include <wincrypt.h>

二：.h文件

public:
CString sReturnXmlString;
CString sExceptionError;
DWORD dwRetValue;
CString szHeaders;
DWORD dwHttpRequestFlags;
CInternetSession session;
CHttpConnection* pServer;
CHttpFile* pHttpFile;
CString strServerName;
CString strObject;
INTERNET_PORT nPort;
DWORD dwServiceType;
bool GetHttpsConnection(CString url);
bool SendRequest(CString *sSendXML,CString strWorkPath);

三：.cpp文件

初始化：

szHeaders = _T("Content-Type: application/x-www-form-urlencoded;Accept: text/xml, text/plain, text/html, text/htm/r/n");
strServerName = "10.130.124.193";
strObject = "";
sReturnXmlString ="";
sExceptionError = "";

函数：

bool CHTTPSDlg::GetHttpsConnection(CString url)//URL地址
{
try
{
if (!AfxParseURL(url, dwServiceType, strServerName, strObject, nPort)) //地址解析
{
AfxMessageBox(_T("Error: can only use URLs beginning with http or https"));
}
session.EnableStatusCallback(TRUE); //session值设置 比如超时
//session.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT,5);
//session.SetOption(INTERNET_OPTION_DATA_RECEIVE_TIMEOUT, 5);
//session.SetOption(INTERNET_OPTION_DATA_SEND_TIMEOUT, 5);

//// The delay value in milliseconds to wait between connection retries.
//session.SetOption(INTERNET_OPTION_CONNECT_BACKOFF,1);
//// The retry count to use for Internet connection requests. If a connection
//// attempt still fails after the specified number of tries, the request is canceled.
//// The default is five.
//session.SetOption(INTERNET_OPTION_CONNECT_RETRIES,1);
// session.SetOption(INTERNET_OPTION_RECEIVE_TIMEOUT, 7000); // 7秒的接收超时
dwHttpRequestFlags = INTERNET_FLAG_NO_AUTO_REDIRECT|INTERNET_FLAG_SECURE;//|INTERNET_FLAG_IGNORE_CERT_CN_INVALID;//|INTERNET_FLAG_IGNORE_CERT_DATE_INVALID;
//if it is not working add below flags
// INTERNET_FLAG_IGNORE_CERT_CN_INVALID | // INTERNET_FLAG_IGNORE_CERT_DATE_INVALID;
pServer = session.GetHttpConnection(strServerName, nPort);
pHttpFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_GET,strObject,NULL,(DWORD)this,NULL,NULL,dwHttpRequestFlags ); // 上传HTTP_VERB_POST 下载HTTP_VERB_GET
if (pHttpFile != NULL)
{
//AfxMessageBox(_T("OpenRequest成功!/r/n"));
}
else
{
AfxMessageBox(_T("OpenRequest失败!/r/n"));
}

}

}
