Postman - 如何从 JSON 响应中获取最后一次出现所需属性的值

Question

我是 JSON 和 Postman 的新手。我相信我正在尝试做一些非常简单的事情。

我创建了一个 GET 请求，它将获得如下所示的 JSON 响应。

在下面的示例中，我想获取最后一个“IsArchived”属性的值（“版本”之前的那个）；或者不属于 FieldGroup 的那个。

我该怎么做？ （尽管可能会通过回答我的其他问题来回答）提前谢谢

Answer 1

这应该很容易，因为您的 IsArchived 属性位于 JSON 响应的顶层，因此除非您以某种方式循环遍历您的 FieldGroups 数组，否则不会使用另一个 IsArchived 值其他问题。

// Convert the response body to a JSON object
var jsonData = pm.response.json()

// Create a variable and assign the value of IsArchived to it
var isArchived = jsonData.IsArchived;

// OR create a Postman environment variable and assign the value of IsArchived to it
pm.environment.set("isArchived", jsonData.IsArchived);

Answer 2

首先，您处理的 JSON 无效。您可以随时使用JSONLint 检查您的 JSON 有效性。

这是有效的 JSON：

{
    "Id": 1328,
    "Name": "AAA Test",
    "Owner": {
        "Id": 208,
        "Name": "The Boss"
    },
    "FieldGroups": [{
            "Id": "c81376f0-6ac3-4028-8d61-76a0f815dbf8",
            "Name": "General",
            "FieldDefinitions": [{
                    "Id": 1,
                    "DisplayName": "Product Name",
                    "IsArchived": false
                },
                {
                    "Id": 2,
                    "DisplayName": "Short Description",
                    "IsArchived": false
                },
                {
                    "Id": 33,
                    "DisplayName": "Long Description",
                    "IsArchived": false
                }
            ]
        },
        {
            "Id": "5ed8746b-0fa8-4022-8216-ad3af17db91f",
            "Name": "Somethingelse",
            "FieldDefinitions": [{
                    "Id": 123,
                    "DisplayName": "Attribution",
                    "IsArchived": false
                },
                {
                    "Id": 1584,
                    "DisplayName": "FC1",
                    "IsArchived": false
                },
                {
                    "Id": 623,
                    "DisplayName": "Sizes",
                    "IsArchived": false,
                    "Owner": {
                        "Id": 208,
                        "Name": "The Boss"
                    },
                    "Unit": "",
                    "Options": [{
                            "Id": 1,
                            "Value": "XS"
                        },
                        {
                            "Id": 2,
                            "Value": "S"
                        },
                        {
                            "Id": 3,
                            "Value": "M"
                        }
                    ]
                }
            ]
        }
    ],
    "IsArchived": false,
    "Version": 1
}

现在我假设你想在 Postman 测试中获取属性，你可以在这里实现：

var responseData = pm.response.json();
var isArchived = responseData.isArchived;
