iOS Youtube 直播 API 错误

Question

我正在尝试开发一个允许用户在 Youtube 上直播的应用程序。我已经使用范围实现了 OAuth 2.0 登录 -

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

现在显示如下:


成功登录后重定向到我的应用程序，我想使用 API- 创建直播流https://www.googleapis.com/youtube/v3/liveStreams 并发布数据。请检查我的以下代码片段 -

    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];
    }];

但每次出现错误 -

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>}

我在这里做错了什么？还有其他访问 youtube api 服务的方法吗？

请帮忙!

提前致谢!

经过大量研究，我得到了解决方案。我们需要调用 Youtube Data API 并且应该在 URL 字符串中提供 API key 和访问 token 。我也在发布代码片段。
在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程序启用。

@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) {

        alert.addTextField(configurationHandler: { (tf: UITextField) in
            tf.placeholder = "Title (required)"
        })
        alert.addTextField(configurationHandler: { (tf: UITextField) in

        })
