ios - AFHTTPSessionManager 设置授权 header

Question

我已经坚持了一段时间，我正在使用 Youtube 的 api，但我一直收到 403 错误。我正在使用负责 OAuth2 的 Google 登录

 NSString *authToken = [[NSString alloc]initWithFormat:@"Bearer %@",[Lockbox unarchiveObjectForKey:@"accessToken"]];

 NSDictionary *parameters = @{@"mine":@"true", @"part": @"contentDetails"};
 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

 manager.requestSerializer = [AFJSONRequestSerializer serializer];
 [manager.requestSerializer setValue:authToken forHTTPHeaderField:@"Authorization"];
NSLog(@"%@----------", authToken); //Prints correct value

 [manager GET:@"https://www.googleapis.com/youtube/v3/channels" parameters:parameters progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

我知道 GET url 是正确的，因为我已经尝试在 OAuth 2.0 Playground 上使用它并且我得到了 200 响应。

下面是我返回的403错误响应

{ status code: 403, headers {
"Cache-Control" = "private, max-age=0";
"Content-Encoding" = gzip;
"Content-Length" = 356;
"Content-Type" = "application/json; charset=UTF-8";
Date = "Sat, 17 Sep 2016 08:18:16 GMT";
Expires = "Sat, 17 Sep 2016 08:18:16 GMT";
Server = GSE;
Vary = "Origin, X-Origin";
"alt-svc" = "quic=\":443\"; ma=2592000; v=\"36,35,34,33,32\"";
"x-content-type-options" = nosniff;
"x-frame-options" = SAMEORIGIN;
"x-xss-protection" = "1; mode=block";

}

我没有在 header 中看到授权字段，但我相信我设置正确并查看了 SO 的正确方法。有没有什么明显的问题，因为我已经卡了几个小时了

NSString *string = [NSString stringWithFormat:@"https://www.google.com/m8/feeds/contacts/default/full/%@?alt=json",contactID];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"DELETE" URLString:string parameters:nil error:nil];
NSString *token = [NSString stringWithFormat:@"Bearer %@",[[GoogleContactManager sharedManager] token]]; //bearer is my personal requirement your's can differ

[req setValue:token forHTTPHeaderField:@"Authorization"];
[req setValue:@"3.0" forHTTPHeaderField:@"GData-Version"];
[req setValue:@"*" forHTTPHeaderField:@"if-match"];
