嗨,我正尝试使用karate.set向json添加新的键和值,但由于无效的变量名称而无法正常工作,以下是我的代码:
Backgroung:
* def myjson = {name: 'test', start_date: '27-04-2017'}
* def localDateTime = Java.type("java.time.LocalDateTime").now()
Scenario:
* string endDate = 'myjson.end_date'
* def endDateTmp = karate.eval(endDate)
* eval if (endDateTmp == null) karate.set(myjson,'$.end_date',localDateTime)
例外:
java.lang.RuntimeException: javascript evaluation failed: if (endDateTmp == null) karate.set(myjson,'$.end_date',localDateTime)
at com.intuit.karate.ScriptBindings.eval(ScriptBindings.java:115)

at com.intuit.karate.Script.evalJsExpression(Script.java:362)
at com.intuit.karate.StepDefs.eval(StepDefs.java:581)
Caused by: java.lang.RuntimeException: invalid variable name: {name:test, start_date:27-04-2017}

at com.intuit.karate.ScriptBridge.set(ScriptBridge.java:101)
at jdk.nashorn.internal.scripts.Script$23$\^eval\_.:program(<eval>:1)
如果密钥已经存在,那么尝试设置是可行的,请建议我如何使用karate.set()或其他任何方式添加新密钥。
谢谢。

我认为您需要更仔细地阅读空手道文档和示例,并且还应该了解一些JS概念。
* def myjson = { name: 'test', start_date: '27-04-2017' }
* def localDateTime = Java.type("java.time.LocalDateTime").now()
* eval if (!myjson.end_date) myjson.end_date = localDateTime + ''
* print myjson
这将导致:
[print] {
"name": "test",
"start_date": "27-04-2017",
"end_date": "2018-07-05T18:13:07.547"
}
请注意,我通过串联将Java Date转换为String。我将介绍如何按照您希望作为家庭作业的方式正确格式化它。请参考此处的示例以获取一些提示:https://github.com/intuit/karate#java-interop
