Rewrite url to the root in the gateway

1

Is there a way to rewrite the url to the root in the gateway? Like this:

  - match:
    - uri: 
        prefix: "/withdrawal"
    rewrite:
      uri: ""

Request routing done in VirtualService not gateway.

If you looking for something to be done at ingress. Can take look at envoy filter.

Hi @prabhu_mannu and @Rodrigo_Valladares,

Given that the rewrite should be in the VirtualService, I haven’t found a way to rewrite to the root uri as Rodrigo demonstrates in his question. For example, a common use case would be if you want to want to rewrite all traffic from a given path to the root of the backend service. The rewrite always adds an extra slash at the beginning of the path on the destination.

For example, say I have a VirtualService that has the following match and rewrite:

  - match:
    - uri: 
        prefix: "/withdrawal"
    rewrite:
      uri: /

What I want to happen is as follows (where myservice is the backend service name):

example.com/withdrawal -> my_k8s_service
example.com/withdrawal/something/ -> my_k8s_service/something

But what I end up seeing is (note the double slash that istio added):

example.com/withdrawal -> my_k8s_service
example.com/withdrawal/something/ -> my_k8s_service//something

I can’t add an empty string

I opened up a stackoverflow question about this as well, as the Istio community guidelines suggest both places for istio help.

Is it possible to rewrite to the root url in istio?

hi
i had on issue rewriting the URL like this
i have two rules

first rule

  - match:
    - uri:
        prefix: /public/api/v1/
    rewrite:
      uri: /api/v1/
    headers:
      request:
        add:
          endpoint: pubilc
      response:
        add:
          endpoint: pubilc
    route:

second rule

  - match:
    - uri:
        prefix: /
    headers:
      request:
        add:
          endpoint: internal
      response:
        add:
          endpoint: internal

maybe try this. I don’t have any issue with double slash, not that i noticed it

Thank you @prabhu-mannu, I think my issue is that I was not adding a trailing slash to the end of my prefix.

When I changed it to look like this, I didn’t see the double slash issue.

  - match:
    - uri: 
        prefix: "/withdrawal/"
    rewrite:
      uri: /
