使用#regex标记出现问题 [英] Trouble using #regex marker
问题描述
我在构造适当的#regex标记时遇到了麻烦.
I'm having trouble constructing a proper #regex marker.
我正在尝试在响应JSON中匹配几种日期格式:
I'm trying to match on a couple of date formats in my response JSON:
"created": "2017-03-23T14:16:25.854Z"
"modified": "2018-06-21T05:38:37.978Z"
"created": "2017-03-23T14:16:25.854Z"
"modified": "2018-06-21T05:38:37.978Z"
我尝试了以下标记:
'#regex [0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}Z'
'#regex [0-9]{4}-[0-9]{2}-[0-9]{2}.[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}.'
'#regex \d+-\d+-\d+.\d+:\d+:\d+.\d+.'
'#regex [0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}Z'
'#regex [0-9]{4}-[0-9]{2}-[0-9]{2}.[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}.'
'#regex \d+-\d+-\d+.\d+:\d+:\d+.\d+.'
所有3种形式似乎都是正确的(根据rubular.com).我也玩过转义可能会出现问题的角色.到目前为止，我唯一能上班的人是:
All 3 forms appear to be correct (according to rubular.com). I've also played around with escaping characters that might be problematic. The only one I been able to get tot work so far is:
[0-9-T:.Z]+
但这感觉有点像模式匹配.
But this feels a little "loose" of a pattern match.
基本上我正在尝试:
* def meta = { created: '#regex[[0-9]{4}-[0-9]{2}-[0-9]{2}.[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}.]', modified: '#regex[[0-9]{4}-[0-9]{2}-[0-9]{2}.[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}.]' }
And match each response ==
"""
{
id: '#regex [a-z0-9]+',
name: '#string',
type: '<Type>',
meta: #(meta),
integration_id: '#uuid'
}
"""
* def meta = { created: '#regex[[0-9]{4}-[0-9]{2}-[0-9]{2}.[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}.]', modified: '#regex[[0-9]{4}-[0-9]{2}-[0-9]{2}.[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}.]' }
And match each response ==
"""
{
id: '#regex [a-z0-9]+',
name: '#string',
type: '<Type>',
meta: #(meta),
integration_id: '#uuid'
}
"""
得到与此类似的错误:
KarateException: objects-api.feature:40 - path: $[0].meta.created, actual: '2016-11-30T20:48:16.782Z', expected: '#regex [0-9]+-[0-9]+-[0-9]+[0-9]+:[0-9]+:[0-9]+[0-9]+', reason: regex match failed
推荐答案
这里是一个建议，为什么不将日期解析为java Date对象，这将带来更多的可能性，例如能够比较2日期.
Here is a suggestion, why don't you parse the dates into java Date objects and that will open up more possibilities such as being able to compare 2 dates.
以下是很好的例子: https://stackoverflow.com/a/54133126/143475 https://stackoverflow.com/a/55938480/143475
Here are good examples: https://stackoverflow.com/a/54133126/143475 https://stackoverflow.com/a/55938480/143475
也就是说，我认为您错过了必须避免使用反斜杠-es的问题，这是Java方面的内容，并在文档中进行了提及.这样就可以了:
That said, I think you missed having to escape the backslash-es, this is a Java thing and is mentioned in the docs. So this works:
* def date = '2017-03-23T14:16:25.854Z'
* match date == '#regex \\d+-\\d+-\\d+.\\d+:\\d+:\\d+.\\d+.'
* match date == '#regex [0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{3}Z'
空手道JS引擎还支持RegExp JS对象，因此请查看此示例是否也为您提供一些解决方案:
The Karate JS engine also supports the RegExp JS object, so see if this example gives you some solutions as well:

编辑，这对我也适用:
* def meta = { created: '#regex \\d+-\\d+-\\d+.\\d+:\\d+:\\d+.\\d+.', modified: '#regex \\d+-\\d+-\\d+.\\d+:\\d+:\\d+.\\d+.' }
* def response = [{ meta: { created: '2017-03-23T14:16:25.854Z', modified: '2018-06-21T05:38:37.978Z' } }]
* match each response == { meta: '#(meta)' }
