Is it possible to use regex expression in origin of cors configuration

[ShahzebAnsari]

I have multiple origin with similar name like abc.def.com, abc.ghi.com, abc.jkl.com etc. I tried to use regex so that I can just defined it in a single line configuration but it doesn't work.

Can you please tell me is it possible or not?

This is not directly managed by Spring Cloud Gateway, but comes from Spring itself. You can see the relevant code here. My reading of this is that the only wild card pattern allowed is '*'.

I was able to use originPatterns in spring-cloud-gateway via global-cors configuration. For example:

spring:
  cloud:
    gateway:
      globalcors:
        corsConfigurations:
          '[/**]':
            allowedOriginPatterns: "https://*.spring.io"
            allowedMethods:
            - GET

Unfortunately, there is an issue with trailing '/' and generic ports as mentioned here: spring-projects/spring-framework#26892
