c++ - WinInet 输出中的随机字符

Question

我有以下代码:

#include <wininet.h>
#include <cstdlib>
#include <iostream>
#include <windows.h>
#include <string.h>

using namespace std;


int main(int argc, char *argv[])
{
    HINTERNET connect = InternetOpen("MyBrowser",INTERNET_OPEN_TYPE_PRECONFIG,NULL, NULL, 0);

   if(!connect){
      cout<<"Connection Failed or Syntax error";
      return 0;
   }

HINTERNET OpenAddress = InternetOpenUrl(connect,"http://shahriar.byethost9.com/com2.html", NULL, 0, INTERNET_FLAG_PRAGMA_NOCACHE|INTERNET_FLAG_KEEP_CONNECTION, 0);

   if ( !OpenAddress )
   {
      DWORD ErrorNum = GetLastError();
      cout<<"Failed to open URL \nError No: "<<ErrorNum;
      InternetCloseHandle(connect);
      return 0;
   }

   char DataReceived[4096];
   DWORD NumberOfBytesRead = 0;
   while(InternetReadFile(OpenAddress, DataReceived, 4096, &NumberOfBytesRead) && NumberOfBytesRead )
   {
           cout << DataReceived;
   }

   InternetCloseHandle(OpenAddress);
   InternetCloseHandle(connect);

   cin.get();
    system("PAUSE");
    return EXIT_SUCCESS;
}

它抓取了http://shahriar.byethost9.com/com2.html的源代码并打印到控制台。

问题是，我页面的源代码是<h5>paint</h5> , 但程序正在打印:<h5>paint</h5>¥ (每次我编辑页面源代码时，最后一个字符都不一样)。

编辑我的页面源后，它变成了:<h5>mspaint</h5> , 但程序再次打印旧源代码 ( <h5>paint</h5>¥ )。

Answer 1

你试过这样积累缓冲吗:

cout << std::string(DataReceived, NumberOfBytesRead);
