使用NSURLRequest上传Youtube视频

Question

我正在尝试使用NSURLRequest将视频上传到youtube。我能够进行身份验证，并且用户和视频也被上传，当检查时它说失败（无法转换视频文件）我没有得到该怎么做，请

构造请求

Authorization = "Bearer ya29.AHES6ZTQ3rJZaf2g3pIYa_7_myg1N_GvQ4VdmJIcapfoqKIfQf-Iow";
Connection = close;
"Content-Length" = 1848078;
"Content-Type" = "multipart/related; boundary=217NH17UDP";
"GData-Version" = 2;
Host = "uploads.gdata.youtube.com";
Slug = "videoFile.mp4";
"X-GData-Key" = "key=AI39si4b-ta8ku-hbsLt73O0rIlOBjpHbITt8WGrwL7OevwjNjl5EFcowlJlBM6kp3rrU1cw64Vobp1l1lJP31Rqavshl4962A";
--217NH17UDP
Content-Type: application/atom+xml; charset=UTF-8
<?xml version="1.0"?>
<entry xmlns="http://www.w3.org/2005/Atom"
xmlns:media="http://search.yahoo.com/mrss/"
xmlns:yt="http://gdata.youtube.com/schemas/2007">
<media:group>
    <media:title type="plain">Sample Video File</media:title>
    <media:description type="plain">
        Description of the sample video
    </media:description>
    <media:category
        scheme="http://gdata.youtube.com/schemas/2007/categories.cat">Music
    </media:category>
    <media:keywords>Keywords</media:keywords>
</media:group>
</entry>
--217NH17UDP
Content-Type: video/mp4
Content-Transfer-Encoding: binary
Video data (NSData)
--217NH17UDP--

如"https://developers.google.com/youtube/2.0/developers_guide_protocol_direct_uploading#Direct_uploading"中所述，

请建议...

Answer 1

您可能

希望将content_type设置为视频/*

Answer 2

只有当您完全按照指定的方式实现请求时，它才能正常工作（即使是单个空格也很重要）

终于可以上传视频了，这里是200%的工作代码。

NSString* const kMetaData = @"<?xml version="1.0"?>rn<entry xmlns="http://www.w3.org/2005/Atom"rnxmlns:media="http://search.yahoo.com/mrss/"rnxmlns:yt="http://gdata.youtube.com/schemas/2007">rn<media:group>rn<media:title type="plain">%@</media:title>rn<media:description type="plain">rn%@rn</media:description>rn<media:categoryrnscheme="http://gdata.youtube.com/schemas/2007/categories.cat">%@rn</media:category>rn<media:keywords>%@</media:keywords>rn</media:group>rn</entry>rn";

    request.HTTPMethod = @"POST";

                               }
                               else
                               {
                                   NSXMLParser *xmlparser = [[NSXMLParser alloc] initWithData:data];
