avoid redirect loops

Reference: https://github.com/nuxt/framework/pull/3908#issuecomment-1079665687

With redirectTo, it is possible to make a loop condition return navigateTo(to.path).

A simple fix would be check and avoid redirect to exact same URL.

In more complex cases, a redirect loop can be nested like a~>b~>a which we could implement with help of a persisted state. (we can wait for this until having session support and benefit from session to hold such state)

@chenmaolan Change your logic. As written that is what is creating the loop. (I don’t know what you are trying to do, or I would make a suggestion, but you never create a condition that will ‘exit’ the loop.

Thanks for your reply, I changed the method, using the state to access the value

I don’t know what your exit conditions are, or how I should write them,

This is a normal routing guard logic @danielroe @pi0 @fanqidong @chenmaolan @
