Question

我尝试创建一个集成了优步API的应用。

我可以获取我的oauth令牌，但是当我尝试刷新令牌但API返回401错误时。我对此端点发出POST请求 https://login.uber.com/oauth/v2/token 有了这个参数：

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

refresh_token是一个var，它包含我连接用户时Uber API返回的refresh_token键。

任何人都知道如何处理刷新我的令牌？

从初始响应中提取时，是否确保打开refresh_token值？我自己尝试了这个并在401中传递了一个未包装的可选结果。
