如何在基于groovy的spring cloud契约中为请求url的服务器端和客户端提供不同的匹配器

import org.springframework.cloud.contract.spec.Contract

Contract.make {
    description "Sample contract"

    request {
        method 'GET'
        url '/api/resource'
        headers {
            contentType applicationJson()
        }
    }

    response {
        status 200
        body([
            message: "Hello, server!"
        ])
        headers {
            contentType applicationJson()
        }
    }
}

import org.springframework.cloud.contract.spec.Contract

Contract.make {

    request {
        method 'GET'
        url '/api/resource'
        headers {
            contentType applicationJson()
        }
    }

    response {
        status 200
        body([
            message: "Hello, client!"
        ])
        headers {
            contentType applicationJson()
        }
    }
}
