Youtube API身份验证
我正尝试使用youtube api的示例代码上传视频。 当我按上传按钮，进度条完成它的过程，但一旦达到点的结束，我得到错误。 错误描述如下：
YouTubeTest [2149：f803]错误 - 错误域= com.google.GDataServiceDomain代码= 400“操作无法完成（com.google.GDataServiceDomain错误400.）”UserInfo = 0x69d5bd0 {}
这是上传按钮按下的代码
- (IBAction)uploadPressed:(id)sender {
[self.view resignFirstResponder];
NSString *devKey = [mDeveloperKeyField text];
GDataServiceGoogleYouTube *service = [self youTubeService];
[service setYouTubeDeveloperKey:devKey];
NSString *username = [mUsernameField text];
NSString *clientID = [mClientIDField text];
NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username
clientID:clientID];
// load the file data
NSString *path = [[NSBundle mainBundle] pathForResource:@"YouTubeTest" ofType:@"m4v"];
NSData *data = [NSData dataWithContentsOfFile:path];
NSString *filename = [path lastPathComponent];
// gather all the metadata needed for the mediaGroup
NSString *titleStr = [mTitleField text];
GDataMediaTitle *title = [GDataMediaTitle textConstructWithString:titleStr];
NSString *categoryStr = [mCategoryField text];
GDataMediaCategory *category = [GDataMediaCategory mediaCategoryWithString:categoryStr];
[category setScheme:kGDataSchemeYouTubeCategory];
NSString *descStr = [mDescriptionField text];
GDataMediaDescription *desc = [GDataMediaDescription textConstructWithString:descStr];
NSString *keywordsStr = [mKeywordsField text];
GDataMediaKeywords *keywords = [GDataMediaKeywords keywordsWithString:keywordsStr];
BOOL isPrivate = mIsPrivate;
GDataYouTubeMediaGroup *mediaGroup = [GDataYouTubeMediaGroup mediaGroup];
[mediaGroup setMediaTitle:title];
[mediaGroup setMediaDescription:desc];
[mediaGroup addMediaCategory:category];
[mediaGroup setMediaKeywords:keywords];
[mediaGroup setIsPrivate:isPrivate];
NSString *mimeType = [GDataUtilities MIMETypeForFileAtPath:path
defaultMIMEType:@"video/mp4"];
// create the upload entry with the mediaGroup and the file data
GDataEntryYouTubeUpload *entry;
entry = [GDataEntryYouTubeUpload uploadEntryWithMediaGroup:mediaGroup
data:data
MIMEType:mimeType
slug:filename];
SEL progressSel = @selector(ticket:hasDeliveredByteCount:ofTotalByteCount:);
[service setServiceUploadProgressSelector:progressSel];
GDataServiceTicket *ticket;
ticket = [service fetchEntryByInsertingEntry:entry
forFeedURL:url
delegate:self
didFinishSelector:@selector(uploadTicket:finishedWithEntry:error:)];
[self setUploadTicket:ticket];
}
我已经从API仪表板正确设置了开发人员密钥和客户端密钥。
我在模拟器上运行这个。 难道我们不能从模拟器上传视频吗？
请指导我我哪里错了？
解决错误...使用Google帐户将视频上传到YouTube时，GData Objective-C的某些功能需要Gmail帐户作为参数，并且一些功能需要YouTube关联帐户作为参数。
当你调用' - （void）setUserCredentialsWithUsername：（NSString *）username password：（NSString *）password;' 在GDataServiceBase中，用户名应该是Gmail帐户，例如'x ... @ gmail.com'，密码应该是Gmail帐户的密码。
但是当你调用'+（NSURL *）youTubeUploadURLForUserID：（NSString *）userID clientID：（NSString *）clientID'' 在GDataServiceGoogleYouTube中，userID参数应该是YouTube关联帐户，密码是Gmail帐户的密码。
我正在使用email_id@gmail.com登录，现在我只是使用email_id登录。多么愚蠢的错误！..但是花了我整整两天的时间来解决.. Duhhh .. !!
