在Swift 3中使用urlsession在http標頭中發送承載令牌的問題

Question

我正在使用urlsession在標頭中發送承載令牌，但是我總是得到未經授權的結果。 我已經看到服務器日志。 我將身體放在那兒但沒有頭。

    let key = UserDefaults.standard.object(forKey: "loginKey") as! String
        print(key)
        let url = NSURL(string: baseurl+"***")

        let request = NSMutableURLRequest(url: url! as URL)

        request.httpMethod = "GET"

        request.addValue("Bearer " + key, forHTTPHeaderField: "Authorization")
        let task = URLSession.shared.dataTask(with: request as URLRequest) 
{(data,response,error) -> Void in

        if error != nil
        {
          print(error?.localizedDescription as Any)
                        return
        }

       do 
       {
          let json = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary

           print(json)
        }
      catch let error as NSError 
      {
         print(error.localizedDescription)
      }
    }
    task.resume()

我也嘗試了request.setValue("Bearer " + key, forHTTPHeaderField: "Authorization")

嘗試這個 ：

     var sessionConfig = URLSessionConfiguration.default
      var authValue: String? = "Bearer \(key)"
     sessionConfig.httpAdditionalHeaders = ["Authorization": authValue ?? <#default value#>]
     var session = URLSession(configuration: sessionConfig, delegate: self as? URLSessionDelegate, delegateQueue: nil)
