Front-end Logout

Update time: 2025-07-23 07:34:21
Edit

Depending on the different terminals and specific usage scenarios, we provide two logout methods: front-end logout and back-end logout:

  • front-end logout: Front-end logout refers to the user accessing the logout address on the front-end. After logging out, the server will clear the user's login status. This logout method generally requires the participation of the browser and needs to be used in the browser environment. The Node SDK provides a method for generating a logout address, and developers can guide users to access this address on the front-end.

  • back-end logout: Back-end logout refers to calling the method of revoking access_token in the back-end service to invalidate the user's access_token and achieve the logout effect. It is suitable for scenarios where the login status is managed using Token.

This part of the document introduces the method of generating a front-end logout link.
