如何确定 Angular 路由重定向的来源？

Question

I have an Angular 6 SPA. Periodically, the app performs an action behind the scenes in an iframe (to silently refresh an OAuth token). Each time my app does this, it redirects to the "/" route. This is undesirable behavior for the reason that if a user is in the middle of completing a form, he will lose his form and be redirected.

I believe that the redirect is happening as a result of something in my code; perhaps a Guard. Is there good a way to determine the source of a route redirect in Angular?

Answer 1

You can enable debug mode for rouuting in angular using enableTracing

RouterModule.forRoot(routes, { enableTracing: true })

You will see there is a lot of event running in the app when using routing. So you can do debug more easily. Hope that help.
