I am new to JSON and Postman.我是 JSON 和 Postman 的新手。 I think I'm trying to do something very simple.
我想我正在尝试做一些非常简单的事情。
I have created a POST request which will get a JSON response like the one below.我创建了一个 POST 请求,它将获得如下所示的 JSON 响应。
In the example below from inside of the FieldGroups
array I want to get the value of Id
but only if the value of Name
is General
在下面来自
FieldGroups
数组内部的示例中,我想获取Id
的值,但FieldGroups
是Name
值为General
How can I do it?我该怎么做? Thanks in advance.
提前致谢。

Postman has built-in support of a JavaScript utility library called Lodash (the _ in the code) and you can use its features to loop through the JSON array in a more consice way. Postman 内置了对名为Lodash (代码中的 _)的 JavaScript 实用程序库的支持,您可以使用其功能以更简洁的方式循环遍历 JSON 数组。
Since I am not exactly sure what you want to achieve, just try to adapt below code to your problem.由于我不确定您想要实现的目标,因此请尝试根据您的问题调整以下代码。
// 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);
}
});
}
I hope I could help.我希望我能帮上忙。
