Developers only need to call the API wx.checkSession to check whether the current user login status is valid. After the login status expires, the developer can call wx.login to obtain the new user login status.

OBJECT parameter description:

The parameter name type is required to indicate whether the successFunction API calls a successful callback function, the login state has not expired, the failed callback function has expired, and the login state has expired. The callback function ended by the API call completeFunctionNo (both successful and failed calls will be executed)

Sample code:

Wx.checkSession ({success: function () {/ / session is not expired and has been valid for the current lifecycle}, fail: function () {/ / login status expires wx.login () / / log in again.
