Question

我正在开展一个项目。我正在使用oauth2和Volley库。我有一个登录网址。首先，我向网址发出请求，以获取access_token，refresh_token和expireIn值。使用access_token我正在登录网址。我能够第一时间成功登录。但是如果令牌过期了。我收到以下错误。我做错了什么？

Answer 1

引用维基百科502 Bad Gateway的定义：“服务器充当网关或代理，并从上游服务器收到无效响应。”还有许多其他5xx服务器错误消息，所有这些消息归结为：“服务器无法满足明显有效的请求。

然后尝试一下。 - ＆GT; Volley with https URLS

使用volley android获得502错误的网关错误
