注销后本地存储数据仍然存在

Question

I'm building a React web app. It stores a token in localstorage after user login through a 3rd party Oauth2 service.

When an user logout, localstorage.clear() did cleared the token.

Storage {length: 0}

However, if I click the brower's back button a couple of times, I'm back in the app, the token re-appear in local storage like I've never logout before.

I've tried:

localstorage.clear(), localStorage.removeItem('accessToken'), location.reload(true) ...

How can I clear out the storage and history?

Answer 1

There's no way of getting back the localstorage value once you clear/removeItem . I'm guessing you're using redux and storing your token somewhere in the store. When you click back, at some point you are probably saving it to the localstorage again.
