Classification of permission verification timing

Pre-verification

The so-called pre-authentication means that the permissions of the internal elements of the currently accessible page are verified before they are displayed. For example: when visitors visit a web page, they cannot see a certain function menu, but administrators can see it, etc. The user experience of pre-verification is good, but the performance is poor

Post-authentication

The so-called post-authentication is simple, that is, the permissions are verified first when accessing each function. For example, click the 'Add Column' button on the page, verify it first, and then execute the add column function code after passing it. Post-verification user experience is poor, but performance is good

Permission verification code implementation location

After the user successfully logs in to the backend, all menu, navigation, and button operations in the backend will be Permission verification is required

But the backend home page, welcome page, user exit and other functions do not require permission verification, which can be customized according to specific project requirements
