Question

我是JSON和Postman的新手。我想我正在尝试做一些非常简单的事情。

我创建了一个POST请求，该请求将获得如下所示的JSON响应。

在下面的示例中，我从FieldGroups数组的内部获取值Id，但前提是Name的值为General

我该怎么办？预先感谢。

{
    "Id": 1328,
    "Name": "AAA Test",
    "Owner": {
        "Id": 208,
        "Name": "The Boss"
    },
    "FieldGroups": [
        {
            "Id": "c81376f0-6ac3-4028-8d61-76a0f815dbf8",
            "Name": "General",
            "FieldDefinitions": [

                },
                {

                    "DisplayName": "Short Description"
                },

Postman内置支持名为Lodash（代码中的_）的JavaScript实用程序库，您可以使用其功能以更简洁的方式遍历JSON数组。

由于我不确定您要实现的目标，因此请尝试使以下代码适应您的问题。

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

// Create a variable to which you will assign the value of Id later on
var generalId;

function setGeneralID() {
    _.each(jsonData.FieldGroups, (arrayItem) => {
        if(arrayItem.Name  === 'General') {
            // Assign the value of Id to the generalId variable
            generalId = arrayItem.Id;

            // OR (depending on what you want to do)
            // Create a Postman environment variable and assign the value of Id to it
            pm.environment.set("Id", arrayItem.Id);
        }
    });
}

希望我能帮上忙。
