如果json字段具有特殊字符作为点，则访问json字段值 [英] access a json field value if the json field has special chars as dots

问题描述

如果我的json文件的字段具有特殊字符(以我的情况为点)，那么如何在空手道中访问字段值?

If I have a json file with fields having special chars (in my case dots) how can I access the field value in Karate?

例如，具有一个名为example.json的json文件

For example having a json file called example.json

{
  "field1" : {
      "field2" : "value2",
      "field.3" : "value3"
  }
}

如果我想获取"field.3"字段的值怎么办?

if I want to get the value of "field.3" field how can do?

  Scenario: read a json file
    * def myJson = read("example.json")
    * match myJson.field1.field2 == "value2"
    * match myJson.field1.field.3 == "value3" # this fails
    * match myJson.field1."field.3" == "value3" # this fails
    * match myJson.field1.'field.3' == "value3" # this fails
    * match myJson.field1.'field\.3' == "value3" # this fails

推荐答案

使用方括号:

* myJson.field1['field.3']
