我正在尝试为用户订阅 youtube 频道。所以用户登录到一个 iOS 应用程序，点击订阅，我会为用户订阅一个预定义的频道。因此，我创建了一个启用了 YouTube 数据 API v3 服务的应用程序。

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}}

任何想法为什么会发生这种情况？

我正在使用示例 youtube 应用程序。

https://developers.google.com/youtube/v3/docs/subscriptions/insert#examples上的示例 url 工作正常，据我所知，我在 objc 代码中做同样的事情。

解决方案是更换：

GTLYouTubeSubscriptionSnippet* snippet = [GTLYouTubeSubscriptionSnippet object];
snippet.channelId = @"UCGRjJrpD2bmk9Ilq6nq80qg";

有了这个：

GTLYouTubeSubscriptionSnippet* snippet = [GTLYouTubeSubscriptionSnippet object];
GTLYouTubeResourceId* resourceObject = [GTLYouTubeResourceId object];
resourceObject.channelId = @"UCGRjJrpD2bmk9Ilq6nq80qg";
