iOS Youtube直播API错误

Question

我想开发一个允许用户在Youtube上直播的应用程序。我已经实施的OAuth 2.0登录使用范围 -

googleapis.com/auth/youtube googleapis.com/auth/youtube.force-ssl

它现在显示是这样的：

成功登录后重定向到我的应用程序，我想要创建直播与API- https://www.googleapis.com/youtube/v3/liveStreams并发布数据以及。请检查我下面的代码片段 -

GTMSessionFetcherService *fetcherService = [[GTMSessionFetcherService alloc] init]; 
    fetcherService.authorizer = self.authorization; 
    NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; 
    [dict setValue:@{@"title":@"FS New Vod", @"description":@"hahahahah its coming now"} forKey:@"snippet"]; 
    [dict setValue:@{@"format":@"360p", @"ingestionType":@"rtmp"} forKey:@"cdn"]; 
    [dict setValue:@{@"isReusable":@"false"} forKey:@"contentDetails"]; 
    NSError *error; 
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict 
                 options:NSJSONWritingPrettyPrinted // Pass 0 if you don't care about the readability of the generated string 
                 error:&error]; 
    NSMutableURLRequest * req = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[@"https://www.googleapis.com/youtube/v3/liveStreams?part=cdn,snippet,contentDetails&onBehalfOfContentOwner=sdfdsfds&onBehalfOfContentOwnerChannel=Ankush_FS&key=" stringByAppendingString:self.authorization.authState.lastTokenResponse.accessToken]] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; 
    req.HTTPMethod = @"POST"; 
    GTMSessionFetcher *ft = [fetcherService fetcherWithRequest:req]; 
    ft.bodyData = jsonData; 
    [ft beginFetchWithCompletionHandler:^(NSData * _Nullable data, NSError * _Nullable error) { 
     if (error) { 
      // OIDOAuthTokenErrorDomain indicates an issue with the authorization. 
      if ([error.domain isEqual:OIDOAuthTokenErrorDomain]) { 
       [self setGtmAuthorization:nil]; 
       [self logMessage:@"Authorization error during token refresh, clearing state. %@", error]; 
       // Other errors are assumed transient. 
      } else { 
       [self logMessage:@"Transient error during token refresh. %@", error]; 
      } 
      return; 
     } 
     NSError *jsonError = nil; 
     id jsonDictionaryOrArray = 
     [NSJSONSerialization JSONObjectWithData:data options:0 error:&jsonError]; 

     // JSON error. 
     if (jsonError) { 
      [self logMessage:@"JSON decoding error %@", jsonError]; 
      return; 
     } 

     // Success response! 
     [self logMessage:@"Success: %@", jsonDictionaryOrArray]; 
    }]; 

但每次得到错误 -

Example-iOS[5413:160436] Transient error during token refresh. Error Domain=com.google.HTTPStatus Code=400 "(null)" UserInfo={data=<7b0a2022 6572726f 72223a20 7b0a2020 22657272 6f727322 3a205b0a 2020207b 0a202020 2022646f 6d61696e 223a2022 676c6f62 616c222c 0a202020 20227265 61736f6e 223a2022 70617273 65457272 6f72222c 0a202020 20226d65 73736167 65223a20 22546869 73204150 4920646f 6573206e 6f742073 7570706f 72742070 61727369 6e672066 6f726d2d 656e636f 64656420 696e7075 742e220a 2020207d 0a20205d 2c0a2020 22636f64 65223a20 3430302c 0a202022 6d657373 61676522 3a202254 68697320 41504920 646f6573 206e6f74 20737570 706f7274 20706172 73696e67 20666f72 6d2d656e 636f6465 6420696e 7075742e 220a207d 0a7d0a>} 

我在这里做什么错？任何其他方式来访问YouTube的API服务？

请帮忙！

在此先感谢！

经过大量的研究，我得到了解决方案。我们需要调用Youtube Data API并在URL字符串中提供API密钥和访问令牌。我也发布了代码片段。 当谷歌登录时，需要添加范围和数据api应该为谷歌开发者控制台中的特定应用启用。

@IBAction func btnYoutubeLiveDidTapped(_ sender: Any) { 
    loaderWillShow(status: true) 
    var scopes = GIDSignIn.sharedInstance().scopes 
    scopes?.append("https://www.googleapis.com/auth/youtube") 
    scopes?.append("https://www.googleapis.com/auth/youtube.force-ssl") 
    scopes?.append("https://www.googleapis.com/auth/youtube.upload") 
    scopes?.append("https://www.googleapis.com/auth/youtubepartner") 
    GIDSignIn.sharedInstance().scopes = scopes 
    GIDSignIn.sharedInstance().signIn() 
} 


func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) { 
    loaderWillShow(status: false) 
    if (error == nil) { 
     let alert = UIAlertController(title: "Broadcast Details", message: "Kindly provide us the following details.", preferredStyle: UIAlertControllerStyle.alert) 
     alert.addTextField(configurationHandler: { (tf: UITextField) in 
      tf.placeholder = "Title (required)" 
     }) 
     alert.addTextField(configurationHandler: { (tf: UITextField) in 
      tf.placeholder = "Description" 
     }) 
     let actionCancel = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel, handler: nil) 
     let actionOkay = UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler: { (action: UIAlertAction) in
