ios google + api youtube订阅频道 [英] ios google+ api youtube subscribe to a channel

问题描述

我正在尝试将用户订阅youtube频道.因此，用户登录到iOS应用程序，单击订阅"，然后我将为该用户订阅预定义的频道. 因此，我有一个启用了YouTube数据API v3服务的应用程序.

I am trying to subscribe a user to a youtube channel. So the user logs in to an iOS app, hits subscribe, and I would subscribe the user to a predefined channel. So I have an app created with the YouTube Data API v3 service enabled.

范围:kGTLAuthScopeYouTube

scope: 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?

Any ideas why would this happen?

我正在使用示例youtube应用.

I am using the sample youtube app.

https://developers.google.com/上的示例网址youtube/v3/docs/subscriptions/insert#examples 可以正常工作，并且据我所知，我在objc代码中正在做相同的事情.

The sample url on https://developers.google.com/youtube/v3/docs/subscriptions/insert#examples works correctly and from what I can tell I am doing the same thing above in objc code.

推荐答案

解决方案是替换:

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

与此:

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