Question

当前，我正在使用 Wininet 来实现HTTP GET请求

下面，我尝试从服务器返回一个时间戳字符串

来触发GET请求

Goal ：获取该字符串的值

发送请求

HINTERNET hSession = InternetOpenA("MyAgent",
INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);

HINTERNET hConnect2 = InternetConnectA(hSession, "10.15.229.111",
   8732, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 1);
HINTERNET hRequest2 = HttpOpenRequestA(hConnect2, "GET",
  "ovs/healthcheck", NULL, NULL, NULL, 0, 1);

HttpSendRequestA(hRequest2, NULL, 0, NULL , 0);

尝试获取响应字符串

DWORD dwContentLen;
DWORD dwBufLen = sizeof(dwContentLen);
if (HttpQueryInfo(hRequest2,
                  HTTP_QUERY_CONTENT_LENGTH | HTTP_QUERY_FLAG_NUMBER,
                  (LPVOID)&dwContentLen,
                  &dwBufLen,
                  0))
{
     DWORD dwReadSize = dwContentLen ;   

     DWORD dwBytesRead;
     char *pCopyPtr = pData;
     InternetReadFile(hRequest2, pCopyPtr, dwReadSize, &dwBytesRead);
     pCopyPtr =  dwBytesRead;

     unsigned char datareturn[20];
 memcpy(datareturn, &pData, 20);
 std::cout << datareturn;           }

快速问题：pData是否从GET请求返回响应字符串。

作为c ++的新手，任何见识都会很棒。谢谢您的时间
