Other information:
When using the Mock feature, requests with the same URL but different methods cannot be correctly matched because the matching is currently only done based on the request URL. For example, cgiMock({url: '/api/users', method: 'GET'}) and cgiMock({url: '/api/users', method: 'POST'}) will both attempt to match the same mock configuration, which can lead to unexpected behavior.

This change introduces method-based matching to resolve the issue, allowing for distinct mock configurations for different request methods on the same URL.
