无法让内容编码显示在获取请求的响应标头中

Question

我正在尝试编写一个空手道测试，以验证特定响应标头是否包含值为 gzip 的 Content-Encoding 标头字段。我尝试了我的 api，其中两次内容编码字段都从空手道的响应中丢失。这两个端点都返回了 postman 和 curl 命令的内容编码字段。

然后我尝试访问 postman-echo 服务以查看空手道遇到问题的是否是我的 api 端点，而且似乎不仅仅是我的 api。有人可以看看我的代码，看看我是否做错了什么以使标题字段显示在响应中？

Feature: test getting Content-Encoding

  Background:
    * url 'https://postman-echo.com/gzip'

  Scenario:
    Given header Accept-Encoding = 'gzip'
    When method get
    Then status 200
    And match responseHeaders contains {'Content-Encoding':'#present'}

这就是空手道请求的样子

1 > GET https://postman-echo.com/gzip
1 > Accept-Encoding: gzip
1 > Connection: Keep-Alive
1 > Host: postman-echo.com
1 > User-Agent: Apache-HttpClient/4.5.12 (Java/1.8.0_252)

响应看起来像

1 < 200
1 < Connection: keep-alive
1 < Content-Type: application/json; charset=utf-8
1 < Date: Fri, 08 May 2020 16:18:42 GMT
1 < ETag: W/"ef-7kclc8pzXTvQiPUaEOf6j95iFaE"
1 < Vary: Accept-Encoding

{
  "gzipped": true,
  "headers": {
    "x-forwarded-proto": "https",
    "x-forwarded-port": "443",
    "host": "postman-echo.com",
    "x-amzn-trace-id": "Root=1-5eb58662-c4aaeec26efd116ac0544a18",
    "accept-encoding": "gzip",
    "user-agent": "Apache-HttpClient/4.5.12 (Java/1.8.0_252)"
  },
  "method": "GET"
}

curl 响应头是

curl --location --request GET 'https://postman-echo.com/gzip' \
> --header 'Accept-Encoding: gzip' -I

HTTP/2 200 
date: Fri, 08 May 2020 16:21:53 GMT
content-type: application/json; charset=utf-8
content-length: 220
content-encoding: gzip

这似乎是 Apache HttpClient 的工作方式或空手道配置方式。我刚刚发现你用karate-jersey 找回了标题：

1 > GET https://postman-echo.com/gzip
1 > Accept: */*
1 > Accept-Encoding: gzip
1 > User-Agent: Jersey/2.30 (HttpUrlConnection 1.8.0_231)

22:40:48.981 [ForkJoinPool-1-worker-1] DEBUG com.intuit.karate - response time in milliseconds: 1177.37
1 < 200
1 < Connection: keep-alive
1 < Content-Encoding: gzip
1 < Content-Length: 248
1 < Content-Type: application/json; charset=utf-8
1 < Date: Fri, 08 May 2020 17:10:48 GMT
1 < ETag: W/"f8-sigbV4PuNI2Fx08AqzMEqW1WIYY"
1 < Vary: Accept-Encoding

因此，如果 Jersey 可以满足您的其余测试，也许这就是您所需要的。让它为karate-apache 工作对我来说不是一个优先事项，所以如果你或其他任何人愿意调查或修复它，那就太好了。
