我正在使用以下代码将照片上传到 Facebook
hconnect = WinHttpConnect(hsession,L"graph.facebook.com",INTERNET_DEFAULT_HTTPS_PORT,0);`hrequest = WinHttpOpenRequest( hconnect, L"POST", reqUrl,NULL, WINHTTP_NO_REFERER,WINHTTP_DEFAULT_ACCEPT_TYPES,WINHTTP_FLAG_SECURE);
CString temp = L"Source:";
temp += objDlg.fileName;
bResult = WinHttpAddRequestHeaders(hrequest,temp,(ULONG)-1L,WINHTTP_ADDREQ_FLAG_ADD );
CString contentType(L"Content-Type:multipart/form-data");
bResult = WinHttpAddRequestHeaders(hrequest,contentType,(ULONG)-1L,WINHTTP_ADDREQ_FLAG_ADD );bResult = WinHttpSendRequest( hrequest,WINHTTP_NO_ADDITIONAL_HEADERS, 0, WINHTTP_NO_REQUEST_DATA, 0,objDlg.fileLength, NULL);
if(bResult)
{
DWORD dwBytesWritten = 0;
bResult = WinHttpWriteData( hrequest,objDlg.memblock, objDlg.fileLength,&dwBytesWritten);}`
但它返回“期望上传文件作为响应。
谁能帮我吗。
提前致谢
