javascript - After the h5 page WeChat authorizes login, the user closes the page and enters again and needs to authorize again

Question

When you authorize again, it will be displayed that you have authorized it recently, and the parameters will not be returned after the completion. How do I know which user it is? I have stored the data locally and the WeChat built-in browser cannot save it. What should I do?

Answer 1

Local is not safe, generally session or similar storage can be used.
