使用GData API将视频上传到youtube错误400 InvalidRequestUriException

Question

我正在尝试使用GData API从我的iPhone应用程序内部向youtube发布视频.这是我正在使用的代码:

GDataServiceGoogleYouTube* service = [self youTubeService];
[service setYouTubeDeveloperKey:youtubeAppKey];

NSString *username = service.username;
NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username];

NSData *data = [NSData dataWithContentsOfFile:self.videoPath];
NSString *filename = @"My Cool Video";
NSString *titleStr = @"Title";
GDataMediaTitle *mediaTitle = [GDataMediaTitle textConstructWithString:titleStr];

NSString *categoryStr = @"Comedy";
GDataMediaCategory *mediaCategory = [GDataMediaCategory mediaCategoryWithString:categoryStr];
[mediaCategory setScheme:kGDataSchemeYouTubeCategory];

NSString *descStr = @"Description";
GDataMediaDescription *mediaDesc = [GDataMediaDescription textConstructWithString:descStr];

NSString *keywordsStr = @"iOS";
GDataMediaKeywords *mediaKeywords = [GDataMediaKeywords keywordsWithString:keywordsStr];

GDataYouTubeMediaGroup *mediaGroup = [GDataYouTubeMediaGroup mediaGroup];
[mediaGroup setMediaTitle:mediaTitle];
[mediaGroup setMediaDescription:mediaDesc];
[mediaGroup addMediaCategory:mediaCategory];
[mediaGroup setMediaKeywords:mediaKeywords];
[mediaGroup setIsPrivate:isPrivate];

NSString *mimeType = [GDataUtilities MIMETypeForFileAtPath:self.videoPath
                                           defaultMIMEType:@"video/mp4"];

GDataEntryYouTubeUpload *entry = [GDataEntryYouTubeUpload uploadEntryWithMediaGroup:mediaGroup
                                                                               data:data
                                                                           MIMEType:mimeType
                                                                               slug:filename];

GDataServiceTicket *ticket = [service fetchEntryByInsertingEntry:entry
                                                      forFeedURL:url
                                                        delegate:self
                                               didFinishSelector:@selector(uploadTicket:finishedWithEntry:error:)];
[self setUploadTicket:ticket];

而且我有这样的回应:

serviceBase:objectFetcher:GTMHTTPUploadFetcher 0x48af0a0(https://uploads.gdata.youtube.com/resumable/feeds/api/users/myCoolMail@gmail.com/uploads?upload_id=heregoesidiremoved)failedWithStatus:400 data:GData InvalidRequestUriException异常消息不可用

我尝试了Google示例代码并获得了相同的结果.我使用了设备和模拟器(5.0).我已经尝试过准备好的视频,只要从iPhone录制一个.我在google API部分创建了Project,并获得了一个应用程序密钥.

拜托,帮我找到问题的解决方案!

Answer 1

问题出在这里:

NSString *username = service.username;
NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username];

不知道为什么会这样,但我已经将userID从"username"更改为kGDataServiceDefaultUser,并且事情开始起作用了.如此简单和如此奇怪,但它确实做到了.

正确的代码:

NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:kGDataServiceDefaultUser];
