在使用此合约的Spring Cloud合约（v1.2.5）中：

    Contract.make {
        description "update sthg"
        request {
            method PUT()
            url value($(consumer('/path/to/sthg'),
                    producer(execute('somePutPathPath(0,\"xxx\")'))))
            body(producer(
                    file('files/givens/my-body.json')
            ))
        }
        response {
            status 200
            headers {
                contentType(applicationJson())
            }
            body(fromRequest().body())
        }
    }

生成测试时出现错误

 org.springframework.cloud:spring-cloud-contract-maven-plugin:1.2.5.RELEASE:generateTests failed:net.minidev.json.parser.ParseException: Unexpected character ({) at position 1. -> [Help 1]

但是如果我使用： body（一些道具：fromRequest（）.body（））一切都很好

    Contract.make {
        description "update sthg"
        request {
            method PUT()
            url value($(consumer('/path/to/sthg'),
                    producer(execute('somePutPathPath(0,\"xxx\")'))))
            body(producer(
                    file('files/givens/my-body.json')
            ))
        }
        response {
            status 200
            headers {
                contentType(applicationJson())
            }
            body(someProp: fromRequest().body())
        }
    }

如何将主体响应设置为请求的主体。
