Hi everyone~

I need to apply the login authentication plug-in to the specified api path.

For example,

- if there is a Route named **‘Route1’** and it’s path is `'/api/phone'`,

- I want to apply the authentication plug-in to all requests under the path of` '/api/phone/sell'`.  
So I built a Route named **‘Route2’** with path:`'/api/phone/sell'`.

But when I actually called it, it was different from what I expected.

When my request path is` '/api/phone/sell'`, the matched Route is **‘Route1’**. Only when my request path is `'/api/phone/sell/abc'` can I match **‘Route2’**.

This has caused me confusion, because I recently upgraded my version of kong from `0.14.x` to `1.3.x`, and there was no such problem in the previous version. Is it because I don’t understand the path matching principle correctly, or is there some adjustments in Kong after a certain version?

All help appreciated 🙂

I know that you can match all requests under the sell path by writing the regular expression `/api/phone/sell[\s\S]*$`, but shouldn’t this be the default operation?
