Wechat applet magic bug - choose to replace the token instead of clearing the token, wx Getstoragesync will take the old token value instead of the new token value

Problem flow description ：

In general , Whenever a user chooses to log out , The code will store the already saved token Values or other data are cleared . When you log in again, you can store the new token value .

But if the code does not include the original token kill , Instead, choose to replace the old value with the new value , There will be a magical bug：

use wx.getStorageSync take token when , Will take the old one token value , Have you ever encountered such a problem ？

Of course, I don't think this is very reasonable , After all, after logging out , You should clean up the old data , The above is just a question for me , Here is the question record

---

what

Why is that ？

Every time a user logs in, they change token value

But if you log in , Not cleared token, Instead, replace it with a new one token, When you jump to a web page outside the applet , Value token It will be the last time token！！！ What's going on here
