空手道 For 循环根据模式获取 ID，然后使用删除功能

Question

我收到了一个 API 电话的回复，它给了我一个设备列表，每个设备都有一个 ID。其中一些设备是 ID 以前缀 'Test' Example Test319244.

开头的测试设备

我希望只检索那些前缀为'Test'的id，可能在一个数组中，并且能够将它们传递给另一个以设备ID为参数的特征文件来删除它。基本上我想删除所有的测试设备。

这是包含所有设备 ID 的示例响应

        {
            "deviceId": "004401784033074000",

        },

            {

                "order": "ASC"
            }
        ]
    }
}

这里在上面的例子中我只想删除ID为Test319244、Test319245和Test319246的设备

如何根据模式 (Testxxxxxx) 获取一组 ID 并将其传递给另一个功能文件

我需要帮助来定义一个 ID 数组，例如：

* def ids = extract the ids based on the pattern
# pass the ids to the delete feature which would send the id one at a time and delete the device.
* def delete = call(delete.feature) ids

这是删除场景功能文件的样子：

  Scenario: Delete Device
    # device_registry_url defined in karate-config.js
    Given url device_registry_url
    And path '/device/'+DeviceID
    And header Authorization = authheader
    And request ''
    When method delete
    Then status 200

这是正确的方法还是我们可以用更好的方法来做？如果是这样，请问有人可以帮忙怎么做吗？

Answer 1

只需使用 karate.filter() 然后你就知道该怎么做了:

* def fun = function(x){ return x.deviceId.startsWith('Test') }
* def filtered = karate.filter(response.items, fun)
* call read('delete.feature') filtered
