我尝试使用GData API从我的iPhone应用程序内部向youtube发布视频。以下是我使用的代码:

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];

我得到了这样的答复:

serviceBase:objectFetcher:GTMHTTPUploadFetcher 0x48af0a0(https://uploads.gdata.youtube.com/resumable/feeds/api/users/myCoolMail@gmail.com/uploads?upload_id=heregoesidiremoved)failedWithStatus:400 data:GData {{ 1}}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。

请帮我找到解决问题的方法!

答案 0 :(得分:10)

问题在于:

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,并且该东西开始工作了。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];
