How can we help?

I have a basic understanding of swagger requestInterceptors which can be used to customize the outgoing requests. In one of my use cases, I need to customize the outgoing request based on URL template selected from the swagger (not from the final URL). How can I identify that?

For example, using the above definition, a user can invoke below

1. GET /{path} with path=person/123 which becomes GET /person%2F123
2. PUT /abc with q=item/123 which becomes PUT /abc?q=item%2F123

From the request interceptor, I need to detect the requests coming through GET /{path} only and URL decode GET /person%2F123 into GET /person/123 before the actual call.

In the request object passed to the requestInterceptor I could not find the required information:

requestInterceptor: (request) => {
}

Start with Swagger UI's requestInterceptor handling and the request object passed to it, then trace how the OpenAPI path templates become final request URLs. Verify the behavior against the supplied GET /{path} and PUT /abc examples; done means the interceptor can distinguish the selected URL template before changing the outgoing request.
