ios google + api youtube订阅了一个频道
我正在尝试将用户订阅到youtube频道。 因此，用户登录到iOS应用程序，点击订阅，我会订阅用户到预定义的频道。 因此，我创建了一个启用了YouTube Data API v3服务的应用。
范围：kGTLAuthScopeYouTube
GTLServiceYouTube *service = self.youTubeService; GTLYouTubeSubscriptionSnippet* snippet = [GTLYouTubeSubscriptionSnippet object]; snippet.channelId = @"UCGRjJrpD2bmk9Ilq6nq80qg"; GTLYouTubeSubscription* subscription = [GTLYouTubeSubscription object]; subscription.snippet = snippet; GTLQueryYouTube *query = [GTLQueryYouTube queryForSubscriptionsInsertWithObject:subscription part:@"contentDetails,snippet"]; [service executeQuery:query completionHandler:^(GTLServiceTicket *ticket, GTLYouTubeSubscription *subscription, NSError *error) { /* Callback */ NSLog(@"subscription:%@", subscription); NSLog(@"error:%@", error); }]; 服务器返回：
error:Error Domain=com.google.GTLJSONRPCErrorDomain Code=-32500 "The operation couldn't be completed. (Required)" UserInfo=0x1005d3c20 {error=Required, NSLocalizedFailureReason=(Required), GTLStructuredError=GTLErrorObject 0x10054faa0: {message:"Required" data:[1] code:-32500}}
任何想法为什么会这样？
我正在使用示例youtube app。
https://developers.google.com/youtube/v3/docs/subscriptions/insert#examples上的示例url正常工作，我可以告诉我在objc代码中执行相同的操作。

解决方案是替换：
GTLYouTubeSubscriptionSnippet* snippet = [GTLYouTubeSubscriptionSnippet object]; snippet.channelId = @"UCGRjJrpD2bmk9Ilq6nq80qg";
有了这个：
GTLYouTubeSubscriptionSnippet* snippet = [GTLYouTubeSubscriptionSnippet object]; GTLYouTubeResourceId* resourceObject = [GTLYouTubeResourceId object]; resourceObject.channelId = @"UCGRjJrpD2bmk9Ilq6nq80qg";
