read得到的结果 前面是一大片空白 我用getlength发现sdata是有数据的 长度227

MyDbgPrintf 的 OutputDebugString 之前设置个断点， 查看 缓冲区变量是否正常， 再看上一级调用传递进来的参数是否对？

噢我知道问题了，我的调试函数打印不出来读取的内容，这是为啥呢..
void MyDbgPrintf(const char* pszFormat, ...)
{
//#ifdef _DEBUG
char szBufFormat[0x1000];
char szBufFormat_Game[0x1008] = "GameData:";
va_list argList;
va_start(argList, pszFormat);//参数列表初始化
vsprintf_s(szBufFormat, pszFormat, argList);
strcat_s(szBufFormat_Game, szBufFormat);
OutputDebugString(szBufFormat_Game);
va_end(argList);
//#endif

setlocale(LC_ALL, "chs"); 这个是设置区域为简体中文，可以解决调试框中文输出乱码的问题，需要在OutputDebugString之前调用， 一般在App类构造时调用一次就可以
我测试的没有问题，试试下面代码，
#include <afxinet.h>
BOOL Test(LPCTSTR strURL, CString &szRecv)
{
BOOL bRet = FALSE;
szRecv.Empty();
CInternetSession intsess;
CHttpConnection *pHttpCon = NULL;
CHttpFile *pHttpFile = NULL;
DWORD dwSvrType = AFX_INET_SERVICE_UNK;
CString strServer, strObject;
INTERNET_PORT nPort = INTERNET_DEFAULT_HTTP_PORT;
CString strUsername, strPassword;
if (AfxParseURLEx(strURL, dwSvrType, strServer, strObject, nPort, strUsername, strPassword, 0)
&& dwSvrType == AFX_INET_SERVICE_HTTP)
{
try
{
//连接服务器
pHttpCon = intsess.GetHttpConnection(strServer, nPort, strUsername, strPassword);
//发送请求
pHttpFile = pHttpCon->OpenRequest(NULL, strObject);
pHttpFile->SendRequest();
//状态200
DWORD dwStatCode = 0;
if (pHttpFile->QueryInfoStatusCode(dwStatCode)
&& dwStatCode == HTTP_STATUS_OK)
{
CStringA sDataA;
//读入数据
while (1)
{
CHAR cData[1024 + 1];
UINT uRd = pHttpFile->Read(cData, 1024);
if (uRd == 0)
break;
cData[uRd] = 0;
sDataA += cData;
}
//输出接收内容
OutputDebugStringA(sDataA);
OutputDebugStringA("\r\n");
#if (defined _UNICODE || defined UNICODE)
//多字节转换到UNICODE
int iWLen = MultiByteToWideChar(936, 0, sDataA, -1, NULL, 0);
MultiByteToWideChar(936, 0, sDataA, -1, szRecv.GetBuffer(iWLen+1), iWLen);
#else //!UNICODE
szRecv = sDataA;
#endif //UNICODE
bRet = TRUE;
}
}
catch (CInternetException* e)
{
e->ReportError();
e->Delete();
}
}
if (pHttpFile)
{
pHttpFile->Close();
delete pHttpFile;
pHttpFile = NULL;
}
if (pHttpCon)
{
delete pHttpCon;
pHttpCon = NULL;
}
intsess.Close();
return bRet;
}
{
setlocale(LC_ALL, "chs");
CString szRecv;
if(Test(_T("http://whois.pconline.com.cn/ipJson.jsp?ip=182.84.29.37"), szRecv))
{
TRACE(_T("%s\n"), (LPCTSTR)szRecv);
}

执行到read 但读到空字符串

什么叫read 读不到数据？ 是没有执行到read 还是读取到的是空字符串？
read 处设置断点，查看读到cData缓冲区的数据是？

前辈我调试之后发现前面都没问题，但read就是读不到数据，我新建一个控制台的空项目用前辈的代码可以读取,,论坛上搜read都是关于乱码的帖子..求助大佬

传递的参数对么？ 设置断点调试下， 调试是程序员必备的基本功
