Hi all ,

I am trying to read a response from a HTTP request. The issue is that I am getting different results when run the binary on Snow-Leopard, Lion and Mountain Lion OS X. The below code works fine on Snow Leopard but not on Lion and ML OS.

Below is the code

#include <CoreFoundation/CoreFoundation.h>
#include <CoreServices/CoreServices.h>

#define YOUTUBE_API_SERVER       "gdata.youtube.com"
#define YOUTUBE_API_VIDEO_FEED   "/feeds/api/videos/"

int main(int argc, char *argv[])
{
    CFStringRef youtubeURLStr;
    youtubeURLStr = CFStringCreateWithFormat(NULL, NULL, CFSTR("http://%s%s%s"), YOUTUBE_API_SERVER, YOUTUBE_API_VIDEO_FEED,"zMa9CT29cQE?fs=1");
    CFShow(youtubeURLStr);
    CFURLRef cfUrl = CFURLCreateWithString(kCFAllocatorDefault, youtubeURLStr, NULL);
    CFHTTPMessageRef cfHttpReq = CFHTTPMessageCreateRequest(kCFAllocatorDefault, CFSTR("GET"), cfUrl, kCFHTTPVersion1_1);

    CFReadStreamRef readStream = CFReadStreamCreateForHTTPRequest(kCFAllocatorDefault, cfHttpReq);
    CFReadStreamOpen(readStream);

    CFHTTPMessageRef cfHttpResp = CFHTTPMessageCreateEmpty(kCFAllocatorDefault, TRUE);

    CFIndex numBytesRead;
    do
    {
        const int nBuffSize = 1024;
        UInt8 buff[nBuffSize];
        numBytesRead = CFReadStreamRead(readStream, buff, nBuffSize);

        if( numBytesRead > 0 )
        {
            CFHTTPMessageAppendBytes(cfHttpResp, buff, numBytesRead);
        }
        else
        if( numBytesRead < 0 )
        {
            CFStreamError error = CFReadStreamGetError(readStream);
        }

    } while( numBytesRead > 0 );


    CFDataRef cfResp = CFHTTPMessageCopyBody(cfHttpResp);
    CFHTTPMessageRef myResponse = (CFHTTPMessageRef)CFReadStreamCopyProperty(readStream, kCFStreamPropertyHTTPResponseHeader);
    CFShow(myResponse);
    CFShow(cfResp);

    CFReadStreamClose(readStream);
    CFRelease(cfUrl);
    CFRelease(cfHttpReq);
    CFRelease(readStream);
    CFRelease(cfHttpResp);

    return 0;
}
