如何对复杂的JSON数组应用if-else

Question

这是示例Json：-

[
    {
    "index": 0,
    "object": {

    "uri": "entities/oAFpSUX",

    "type": "configuration/entityTypes/Pet",

    "updatedBy": "abc@xyz.com",

    "updatedTime": 1531431177691,

    "attributes": {

        "Weight": [

            {

                "label": "5 lbs",

                            "value": "5",

                        }

                        }

                    ]

                },

                "ov": true,

                    "Type": [

                        {

                            "ov": false,

                            "value": "CRMO_Pet_Id",

                        }

                    ],

                    "ID": [

                                    "value": "3"

                                }

                            ],

                            "uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9yGr/Type/1AeFvA2X7"

                    "ExpirationDate": [

                "value": {

                    "Type": [

                        {

                            "type": "configuration/entityTypes/Pet/attributes/Vaccination/attributes/Type",

                            "ov": true,

                            "value": "Distemper",

                            "lookupAttributes": [
                                {
                                    "name": "Sort Order",
                                    "value": "4"
                                }
                            ],
                            "uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9YhJ/Type/1AeFv9cxZ"
                        }
                    ],....

我的问题：我能够将“ $ .. Vaccination..value.Type..value”的值获取为“ Bordatella”，这样可以正常工作。但是，我现在想要的是，如果值是“ Bordatella”，那么我想提取“ ExpirationDate”下的“ value”。有人可以帮我如何在“ ExpirationDate”下提取该“值”吗？我不确定是否需要使用一些使用jmeter的if控制器的自定义Groovy代码来做到这一点。任何帮助将不胜感激！

谢谢。

Answer 1

有几种方法可以在Java内部运行jq查询，例如

• https://github.com/eiiches/jackson-jq
• https://github.com/arakelian/java-jq（可从Maven Central获得）
• Java本机访问包装器https://github.com/bskaggs/jjq。受支持的平台仅是Linux。

假设已对示例输入进行了明显修改以使其有效JSON，则以下jq过滤器将产生如下所示的输出：

.[].object.attributes.Vaccination[].value
| select(.Type[].value == "Bordatella")
| .ExpirationDate[].value

输出：

"2018-10-26"

替代

这是一个jq过滤器，它与“疫苗接种”对象的相对位置无关：

  ..
  | objects
  | select(has("Vaccination"))
  | .Vaccination[].value?
  | select(.Type[].value == "Bordatella")
  | .ExpirationDate[].value

给出以下JSON响应：

              ]
            },
            "ov": true,

                  "value": "Distemper",
                  "lookupAttributes": [
                    {
                      "name": "Sort Order",
                      "value": "4"
                    }
                  ],
                  "uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9YhJ/Type/1AeFv9cxZ"
                }
              ]
            }
          }
        ]
      }
    }
  }
]

1. 将JSR223 PostProcessor添加为返回上述响应的请求的子项

2. 将以下代码放入“脚本”区域：

   new groovy.json.JsonSlurper().parse(prev.getResponseData()).get(0).get('object').get('attributes').get('Vaccination').each { vaccination ->
       if (vaccination.get('value').get('Type').get(0).get('value').equals('Bordatella')) {
           def expirationDate = vaccination.get('value').get('ExpirationDate').get(0).get('value')
           log.info('ExpirationDate: ' + expirationDate)
           vars.put('ExpirationDate', expirationDate)
       }
   }
   

3. 如果一切顺利（您的JSON响应与Groovy代码匹配），ExpirationDate将为：

   • 打印到 jmeter.log 文件
   • 存储为${ExpirationDate} JMeter变量
