刷新超級令牌Swift

Question

我嘗試創建一個與Uber API集成的應用程序。

我可以得到我的oauth標記，但是當我嘗試刷新標記但API返回401錯誤。 我做一個POST請求到這個端點 https://login.uber.com/oauth/v2/token 有了這個PARAMS：

let params = ["client_secret": ***********, "client_id": ***********, "grant_type": "refresh_token", "redirect_uri": "REDIRECT_URI", "refresh_token": refresh_token] 

refresh_token是當我連接用戶，其包含尤伯杯API的refresh_token鍵返回一個變種。

任何人有任何想法如何處理刷新我的令牌？

感謝

ViewController.swift

UberManager.refreshToken { (changed) -> Void in 
    if let change = changed { 
     print("token renewable") 
    } 
} 

UberManager.swift

public class UberManager { 
    static func refreshToken(completionHandler:(changed: Bool?) -> Void) -> Void { 
      Router.RefreshToken().performRequest { (json, error) -> Void in 
       if error == nil { 
        print(json) 
       } 
      } 
     } 
    } 

Router.swift

      return ParameterEncoding.URL.encode(mutableURLRequest, parameters: params).0

        case 201:

從最初的響應中提取時，您是否確保展開refresh_token值？我自己試了一下，並在一個401.中打開可選的結果。
