我可以在同一个json文件中的另一个对象中引用一个json对象吗? [英] Can I refer to one json object in another object in the same json file?

问题描述

我正在尝试使用json开发测试自动化框架来描述数据. 我有一个看起来像这样的json文件:

I'm trying to develop a test automation framework using json to describe data. I have a json file which looks like this:

{
  "preparation":{
    "configuration":[
      {
        "config1":{
          "src_configfile":"/home/xxx/etc/src_config1.cfg",
          "dest_configfile":"/home/xxx/etc/abc.cfg"
        }
      },
      {
        "config2":{
          "src_configfile":"/home/xxx/etc/src_config2.cfg",
          "dest_configfile":"/home/xxx/etc/xyz.cfg"
        }
      }
    ],
    "executable_info1":[
      {
        "login_info":{
          "hostname":"abc.dw",
          "username":"xyz",
          "password":"*******"
        }
      },
      {
        "command":{
          "folderpath":"/home/xxx/yyy/bin",
          "processname":"sys.exe",
          "parameters":"-d"
        }
      }
    ],
  },
  "execution":[
    {
      "test_case1":{
        "folderpath":"/home/xxx/testscripts",
        "scriptname":"test_case1.py",
       ***???????????Can I access the config1 object here???????????? 
       "config_file"="preparation.configuration[0].config1.dest_configfile"***
      }
    },
    {
      "test_case1":{
        "folderpath":"/home/xxx/testscripts",
        "scriptname":"test_case2.py",
        ***"config_file"="preparation.configuration[1].config2.dest_configfile"***
      }
    }
  ]
}

我需要针对不同的测试用例使用不同的配置文件.我可以在执行中引用准备对象的config1对象吗???

I need to use different config files for different test cases. Can I reference the config1 object of preparation object in the execution???

推荐答案

不，您不能这样做，至少不能直接这样做.首先，JSON不支持循环引用.

No, you can't do that, at least not directly. For a start, JSON doesn't support circular references.

您可能会考虑使用诸如jsonpath之类的库，该库允许您按模式引用元素，但是无论值是实际值还是对其他分支的引用，您都倾向于先验.

You might consider using a library such as jsonpath that allows you to reference elements by pattern, but you would tend to need apriori whether a value was an actual value or a reference to some other branch.
