Wiremock Capture path param and return in the response body

I am trying to create dynamic mocks using WireMock. I have a situation where if I specify URL like :

http://localhost:8089/api/account/abc@abc.com

then I should receive response like:

{ 
  "account" : "abc@abc.com" 
}

In brief, the path param is returned in the response body. I am able to make the request URL generic by using urlPathPattern set to /api/account/([a-z]*) however, I am not sure how should I capture abc@abc.com and return this in the response using regular expressions.

In WireMock the regular expressions can be used to recognize the email format in the Request Matching. For the purpose of this example I used a very crude example. Your production implementation may require a more robust approach.

This request:

http://localhost:8181/api/account/someone@somewhere.net

Is matched by this rule:

{
    "request": {
        "method": "GET",
        "urlPathPattern": "/api/account/([a-z]*@[a-z]*.[a-z]*)"
    },
    "response": {
        "status": 200,
        "jsonBody": {
            "account": "{{request.path.[2]}}"
        },
        "transformers": ["response-template"],
        "headers": {
            "Content-Type": "application/json"
        }
    }
}

And returns this response:

{
  "account": "someone@somewhere.net"
}

It makes use of a Response Template processing functionality in WireMock. The Request Model variables [{{request.path.[2]}}] can be used to obtain sections from the request.
