从一页读取的问题 [英] Problem For Read From One Page

问题描述

我的C ++代码有一个非常奇怪的问题.
我的代码的一部分连接到一个网站的特定页面，并读取一个数字(例如，数字45814).我的代码可以在所有服务器上正常工作，但是最近我在特定服务器上遇到了问题.从该页读取的数字显示为"458140"而不是"45814".我的意思是它在数字上加一个零.我的代码如下:

Hi,
I got very strange problem with my C++ code.
One section my code connect to specific page of one website and read one number(for example number 45814). My code working good with all servers but recently I got problem with specific server. When read number from this page shows number "458140" instead "45814". I mean it adds one zero to number. my code is as below:

char* __stdcall Get_Account_Number_FromWEB()
{
	
		
	std::string strTopic = "get account from web";
	//!!!! this is to be replaced with our request	
	const char * szPlimusRef = gpVar->m_strPlimusRef.c_str();
	std::string strHttpReq = "http://www.example.com/1.htm"; // sample page
	
	HINTERNET webHANDLE =  InternetOpen(strTopic.c_str(), 0, "0", "0", 0);
	HINTERNET webResult = InternetOpenUrlA(webHANDLE, strHttpReq.c_str(), "0", 0, -2080374528, 0);
	if ( webResult )
	{
		char szwebBuffer[1024];
		memset(szwebBuffer,0,sizeof(szwebBuffer));
		DWORD dwBytes = sizeof(szwebBuffer);
		DWORD dwBytesActual = 0;
		BOOL bRead = InternetReadFile(webResult, szwebBuffer, dwBytes, &dwBytesActual);
		InternetCloseHandle(webResult);			
		
		gpVar->m_strWEBDigest = (char*)szwebBuffer;
	}
	else
	{
		gpVar->m_strWEBDigest = "No internet connection";
	}
	InternetCloseHandle(webHANDLE);	
	
	return (char*)gpVar->m_strWEBDigest.c_str();
	
	
} 

手动打开此页面时，我看到"45814"，但读取此功能时显示"458140".

我用另一台服务器检查了这一切是否正常，但是只有一台服务器遇到了这个奇怪的问题. 谁能解决这个问题?
问候

When open this page manually I see "45814" but when this function read that shows "458140".

I checked this with different server all works correctly but only one server got this strange problem.
Can anybody solve this problem?
Regards,

推荐答案

检查已读取的字节(dwBytesActual)并终止字符串:

Check the bytes readen (dwBytesActual) and terminate the string:

szwebBuffer[dwBytesActual]=0;

问候.
