# VC实现http发送get和post请求 #

## get请求 ##

首先通过前面介绍的抓包工具获取请求的详细内容，然后再通过VC拼接Header，函数如下：

bool CXXX::http_get_eng_mode()
    {
    	//<?xml version=\"1.0\" encoding=\"US-ASCII\"?> 
    
    
    <RGW><param><method>call</method><session>000</session><obj_path>cm</obj_path><obj_method>get_wan_configs</obj_me
    
    
    thod></param></RGW>
    	CString strURL=_T("http://")+loginfo.strIPAddress+_T("/xml_action.cgi?
    
    
    method=get&module=duster&file=wan");
    	bool bResult = false;
    	DWORD dwType = 0;
    	CString strServer;
    	CString strObject;
    	INTERNET_PORT wPort = 0;
    	DWORD dwFileLength = 0;
    
    
    	bResult =  AfxParseURL(strURL, dwType, strServer, strObject, wPort);
    	if(!bResult)
    	{
    		return false;
    	}
    	int iCount=0;
    	bool bRet=true;
    	while (bRet)
    	{
    		if (iCount>2)
    		{
    			bRet=false;
    		}
    		try
    		{
    			CInternetSession Session ; 
    			CHttpConnection *pHttpConnect = Session.GetHttpConnection(strServer, wPort) ;
    			if(pHttpConnect)
    			{
    				CHttpFile* pFile = pHttpConnect->OpenRequest( CHttpConnection::HTTP_VERB_GET, 
    					_T("/xml_action.cgi?method=get&module=duster&file=wan")); //
    				if ( pFile )
    				{
    					CString strAuthHeader=getAuthHeader
    
    
    (loginfo.strAdmin,loginfo.strPassword,"GET");
    					pFile->AddRequestHeaders(strAuthHeader);

    					CString strTemp=_T("");strTemp=_T("Referer:

    					pFile->AddRequestHeaders(strTemp);
    					pFile->AddRequestHeaders("Accept-Language: zh-CN");
    					pFile->AddRequestHeaders("Accept-Encoding: gzip, deflate");
    					pFile->AddRequestHeaders("User-Agent: Mozilla/5.0 (Windows NT 6.1;

    					CString strHost=_T("Host: ")+loginfo.strIPAddress;
    					pFile->AddRequestHeaders(strHost) ;
    					pFile->AddRequestHeaders("Connection: Keep-Alive");
    					pFile->AddRequestHeaders("Cookie: locale=en; platform=mifi") ;
    
    
    					if (!pFile->SendRequest())
    					{
    						pFile->Close();
    						pHttpConnect->Close();						
    						return false;
    					}
    					
    					DWORD dwStateCode = 0;
    					pFile->QueryInfoStatusCode(dwStateCode);
    					if(dwStateCode == HTTP_STATUS_OK) 
    					{
    						CString strInfo1;
    						DWORD dw1=0;

    						CString strInfo2;
    						DWORD dw2=0;
    						pFile->QueryInfo(HTTP_QUERY_CONTENT_BASE ,strInfo2 ,&dw2);
    						char content_return[1024*10];memset(content_return,0,1024*10);
    						pFile->Read(content_return, SERVER_CONTENT_LEN);
    						
    						//解析xml，查询工程模式
    						CString str=getEngMode_1802(_bstr_t(content_return));
    						if (!str.IsEmpty())
    						{
    							if (!IsEngModeOpen(0,str))
    							{
    								//如果没有开启的话，需要先打开
    								http_set_eng_mode_1802(true);
    							}
    						}
    						else
    						{
    							bResult=false;
    						}						
    					}
    					else
    					{
    						bResult=false;
    					}
    					pFile->Close();
    					delete pFile ;
    					bRet=false;
    				}
    				pHttpConnect->Close() ;
    				delete pHttpConnect ;
    			}
    		}
    		catch( CInternetException *e )
    		{
    			e->Delete();    
    		}
    	}
    	return bResult;
    }

## post请求 ##

    					pFile->AddRequestHeaders(strCookie1);
    
    
    					if(!pFile->SendRequest(NULL,0,(void*)requestData.GetBuffer

    				pHttpConnect->Close() ;
    				delete pHttpConnect ;
    			}
    		}
    		catch( CInternetException *e )
    		{
    			e->Delete();    
    		}
    	}
    	return bResult;
    }

较get请求而言，主要是除了Header外还需要post数据。
