当重复使用另一个目录中的一个功能时，无法转换为映射。

Question

我读过：https://stackoverflow.com/search?q=%5Bkarate%5Dcannot+convert+to+map和https://github.com/intuit/karate/issues/544

我用空手道-0.8.0

我有一个将在目录中重复使用的特性，内容如下：

@ignore
Feature:

  Background:
    * url baseUrl
    * def Sign = Java.type('cruiser.token.Sign')
    * configure afterScenario =
    """
    function() {
      if (karate.info.errorMessage != null) {
        karate.log(karate.info.errorMessage);
      }
    }
    """
  Scenario:
    * def ck = Sign.execute('#(uid)')
    * path '/rest/n/rt/upload'
    * cookies ck
    * multipart fields  '#(fo)'
    * multipart file rt = { read: 'classpath:cruiser/http/rt/A/123.mp3', filename: '123.mp3', contentType: 'audio/mp3' }
    * method post
    * status 200
    * match response contains { result: 1 }

还有B目录中的另一个特性文件，内容如下：

Feature:
Background:
  Scenario:
    * def fo =
    """
    {
      'title': '你好！',
      'description': '很好听哦'
    }
    """
    * def x = call read('classpath:cruiser/http/rt/A/upload-base.feature') { uid: 33, fo: '#(fo)' }
    * match x.response contains { result: 1 }
    * print x.response.feed.id

它的跑步者名为XRunner.java

当mvn test -Dtest=XRunner时，错误信息：

Running cruiser.http.rt.B.XRunner

cannot convert to map:  '#(fo)'
Failed scenarios:

Answer 1

这两行都错了：

* def ck = Sign.execute('#(uid)')
* multipart fields  '#(fo)'

读这个：https://github.com/intuit/karate#rules-for-embedded-expressions

在空手道中，默认情况下表达式是纯JS。所以就这么做：

* def ck = Sign.execute(uid)
* multipart fields fo
