在 Youtube api 中创建播放列表

Question

我查看了 Youtube 的文档，但我似乎不明白如何专门为 ios 用户创建播放列表。我知道用户需要使用 OAuth 2 登录才能授予应用访问/授权以创建播放列表

文档链接：https://developers.google.com/youtube/v3/sample_requests#uploaded_videos

然后给出这个代码：

POST {base_URL}/playlists?part=snippet
 Request body:
{
'snippet': {
  'title': 'New playlist', 
  'description': 'Sample playlist for Data API',
 }
}

我不确定如何将其翻译为适用于 ios。我将如何在目标 c 中反映请求正文对象？

--------更新----- 它只是使用 NSURLSessionUploadTask 吗？所以我可以发送一个帖子请求，也可以为请求正文发送一个字典？不好意思，对IOS空间有点新意

这里是更新！

来自 Google 的客户端库已更新。

文档：YouTube Data API Overview

播放列表文档：Playlists: insert

GitHub 客户端库：Google APIs Client Library for Objective-C For REST

这里是需要安装的 pod：

pod 'GTMSessionFetcher'
pod 'GTMOAuth2'
pod 'GoogleAPIClientForREST/YouTube’

如果我们认为我们有 clientID、clientSecret 和 scope（阅读文档），那么我们可以创建 viewController 进行身份验证：

GTMOAuth2ViewControllerTouch *viewController = [[GTMOAuth2ViewControllerTouch alloc]
                                                    initWithScope:scope
                                                    clientID:kMyClientID
                                                    clientSecret:kMyClientSecret
                                                    keychainItemName: nil
                                                    completionHandler:
                                                    ^(GTMOAuth2ViewControllerTouch *viewController, GTMOAuth2Authentication *auth, NSError *error) {
                                                        [self dismissViewControllerAnimated:NO completion:nil];
                                                        if (!error)
                                                        {
                                                            GTLRYouTubeService *youTubeService = [[GTLRYouTubeService alloc] init];
                                                            youTubeService.authorizer = auth;
                                                            [self createPlaylistWithTitle: @"Title" description: @"description" youtubeService: youtubeService];
                                                        }
                                                    }];
[self presentViewController:viewController animated:YES completion:nil];

创建私有播放列表的方法：

- (void)createPlaylistWithTitle:(NSString *)playlistTitle description:(NSString *)playlistDescription youtubeService:(GTLRYouTubeService *)youTubeService
{
    GTLRYouTube_Playlist *playlist = [[GTLRYouTube_Playlist alloc] init];

    GTLRYouTube_PlaylistSnippet *playlistSnippet = [[GTLRYouTube_PlaylistSnippet alloc] init];
    playlistSnippet.title = playlistTitle;
    playlistSnippet.descriptionProperty = playlistDescription;

    GTLRYouTube_PlaylistStatus *playlistStatus = [[GTLRYouTube_PlaylistStatus alloc] init];
    playlistStatus.privacyStatus = @"private";

    playlist.snippet = playlistSnippet;
    playlist.status = playlistStatus;

    GTLRYouTubeQuery_PlaylistsInsert *query = [GTLRYouTubeQuery_PlaylistsInsert queryWithObject:playlist part:@"snippet,status"];
    [youTubeService executeQuery:query completionHandler:^(GTLRServiceTicket *ticket, id object, NSError *error) {
        if (!error)
        {
            NSLog(@"response: %@", object);
        }
    }];
}

Answer 2

您是对的，您需要使用OAuth 2.0 授予应用程序访问权限以创建播放列表。通常最好的做法是在需要访问时增量请求范围，而不是预先请求。

这里有一段代码 sn-p 如何在 IOS 中通过 YouTube API 创建播放列表：

GTMOAuth2ViewControllerTouch *viewController = [[GTMOAuth2ViewControllerTouch alloc]
initWithScope:scope
clientID:clientId
clientSecret:clientSecret
keychainItemName:keychainItemName
completionHandler:
^(GTMOAuth2ViewControllerTouch *viewController, GTMOAuth2Authentication *auth, NSError *error) {
if (error) {
[SVProgressHUD showErrorWithStatus:error.localizedDescription];
} else {
GTLServiceYouTube *service = [FZMYoutubeSearchService sharedYoutubeService];
service.authorizer = auth;

GTLYouTubePlaylist *playlist = [[GTLYouTubePlaylist alloc] init];

GTLYouTubePlaylistSnippet *playlistSnippet = [[GTLYouTubePlaylistSnippet alloc] init];
playlistSnippet.title = @"this is my great playlist";
playlistSnippet.descriptionProperty = @"and this is description";

GTLYouTubePlaylistStatus *playlistStatus = [[GTLYouTubePlaylistStatus alloc] init];
playlistStatus.privacyStatus = @"private";

playlist.snippet = playlistSnippet;
playlist.status = playlistStatus;

GTLQueryYouTube *query = [GTLQueryYouTube    queryForPlaylistsInsertWithObject:playlist part:@"snippet,status"];
[service executeQuery:query completionHandler:^(GTLServiceTicket *ticket,      id object, NSError *error) {
if (error) {
NSLog(@"error: %@", error);
