在功能文件中使用 karate-config 参数

Question

空手道 header examples 没有显示如何访问 baseUrl 以外的配置值。当我切换环境（作为运行命令的一部分传入 -Dkarate.env=qual 时）然后 baseUrl 设置正确。

问题是，我想使用其他配置值 as shown here 但是当我运行测试时，它无法正确访问 config.ApiKey。相反，我收到此错误

我的.feature文件和karate-config.js在下面。

XYZ.feature

@regression
Feature: Checkdigit Algorithm API

Background:
* url baseUrl
* def secretKey = config.apiKey
* configure ssl = true

Scenario Outline: Testing XYZ algorithm

* configure headers = { KeyId: secretKey, Accept: 'application/json' }
Given path 'headers'
And param url = baseUrl
And params { customerId: '<custcode>', algoId: '<algo>' }
When method get
Then status <val>

Examples:
  | algo   | custcode      | val   | comment |
  | XYZ    | 2110974841    | 204   | Valid |
  | XYZ    | 7790011614    | 204   | Valid |
  | XYZ    | 5580015174    | 204   | Valid |
  | XYZ    | 2110974840    | 400   | expected check digit 1 |
  | XYZ    | 211097484     | 400   | not 10 digits |
  | XYZ    | 211097484x    | 400   | not numeric |

空手道-config.js

function() {    
  //set up runtime variables based on environment
  //get system property 'karate.env'
  var env = karate.env;
  if (!env) { env = 'dev'; }  // default when karate.env not set

  // base config
  var config = {
    env: env,
    baseUrl: 'https://localapi.abc123.example.com/api/v1/validate/customerid',
    apiKey: ''
  }
  //switch environment
  if (env == 'dev') {
  config.baseUrl = 'https://devapi.abc123.example.com/api/v1/validate/customerid';
  config.apiKey  = 'fake-1ba403ca8938176f3a62de6d30cfb8e';
  } 
  else if (env == 'qual') { //Pre-production environment settings
  config.baseUrl = 'https://qualapi.abc123.example.com/api/v1/validate/customerid';
  config.apiKey  = 'fake-d5de2eb8c0920537f5488f6535c139f2';
  }

  karate.log('karate.env =', karate.env);
  karate.log('config.baseUrl =', config.baseUrl);
  karate.log('config.apiKey =', config.apiKey);

  return config;
}

（此处有类似问题，使用单独的 headers.js：https://github.com/intuit/karate/issues/94）

Answer 1

请记住，karate-config.js 返回的 JSON 对象中的所有键 都将作为变量注入，仅此而已。所以你将无法引用config，但你肯定可以引用apiKey。

我想如果你做这个简单的改变，事情就会开始起作用：

* def secretKey = apiKey

另外，我觉得你的场景第一行有问题，应该是：

* configure headers = { KeyId: '#(secretKey)', Accept: 'application/json' }

Answer 2

仅供参考，我的最终正确工作 XYZ.feature 文件现在看起来像这样。 Given path 'headers' 行导致 header 信息悄悄进入 url，因此已将其删除。
