如何在 JSON 中查找和计算所有对象答案

【问题标题】：How do i find and count all objects in JSON如何在 JSON 中查找和计算所有对象
【发布时间】：2023-04-08 06:24:01
【问题描述】：

我需要找出在休息 API 请求中我有多少带有 ID 的项目。我想计算我有多少带有 ID 的项目，而不是我需要为它们分配一个变量。这怎么能在 JSON 中完成。我知道我有 4 个带有 id 的对象，但是随着我在 blazemeter 上运行更多测试，这可能会发生变化。计数的 ID 需要有一个分配的变量，以便我可以在 url 中使用该变量来查看会话 ID。

【解决方案1】：

console.log(pm.response.json().result.filter(a=>a.id).length)

this 为结果数组中的所有元素提供属性 id，然后返回其长度

【解决方案2】：

如果您需要存储所有 id，我认为没有办法在邮递员中存储列表，但您可以将所有 id 存储为逗号分隔的字符串，如下所示：

var jsonData = JSON.parse(responseBody);
var arr = ""
for (var i = 0; i<jsonData.result.length; i++){
    arr += jsonData.result[i].id + ','
}
pm.environment.set("ids", arr);
