Company internal project with a service within the monitoring page want to use the crawler to obtain state, but the service management page using the CAS certification (general principle is to intercept access request, determine whether a user token, if not or have but token has expired is redirected to the login screen, when login login interface is completed, will return within the corresponding with a certification by the cookie token, and then redirected to the originally trying to access the address, rejudge)

CodePudding user response:

If the cas certification without the climb, it also the login interface to do the login
