@qfdk 其实并没有解决，因为get方法调用授权接口并没有返回token，也并没有存在本地，请求时用的是由账号密码组合生成的授权码，这时候按照程序逻辑，每次启动会因为读取不到本地token，每次都进去登录界面。

@ufolux

Because the Get method call authorization interface does not return token and does not save token locally.

the request is made with the authorization code generated by the combination of account and passwords.

At this time, according to the program logic, every time start app will enter the login page because the local token can not be read.
