Wiremock 返回编码错误的响应

如何解决Wiremock 返回编码错误的响应

我在 windows 上使用 spring-cloud-contract wiremock 来模拟一些 rest api 端点，如下所示：

    def "returns status 200 for accounts route"() {
        when:
        stubFor(
            get(urlPathMatching("/v1/user/isEligible.*"))
                    .willReturn(
                    aResponse()
                    .withHeader("content-type","application/json;charset=UTF-8")
                    .withBody("{}")
                    ))

日志显示如下：

Matched response deFinition:
{
  "status" : 200,"body" : "{}","headers" : {
    "content-type" : "application/json;charset=UTF-8"
  }
}

Response:
HTTP/1.1 200
content-type: [application/json;charset=UTF-8]

有谁知道为什么响应正文被编码为：�� C���
