Question

在其他线程上寻找了一段时间，并且问题没有得到如何在数组中获取JSON对象我已经看过的问题- How to get JSONobject from JSONArray in postman
How to get array from JSON Object?

到目前为止我尝试过的-

var jsonData = JSON.parse(responseBody);
var jsonObject = jsonData.events[2];
console.log("jsonobject - " + jsonObject);

控制台输出-

jsonobject - [object Object]

json响应看起来像这样-

[
 {

        "$ts": "2019-06-14T06:21:55.2221392Z",
        "values": [
            "43912",
            "CountIn",
            "neet.row.mac3.indexinput",
            "mac3",
            "mac3",

Answer 1

看起来您正在获取对象，但是控制台将其打印为[object Object]。尝试打印jsonObject.$ts或jsonObject.values[0]，以查看对象是否包含您要查找的数据。

Answer 2

发生这种情况是因为jsonObject是对象的对象，因此当您说console.log（jsonObject）时，它将在邮递员的控制台中显示对象值。但当邮递员控制台附加到字符串消息后，它不会在控制台中显示对象的值。要查看对象stringify中的值，它就像这样-

console.log("jsonobject - " + JSON.stringify(jsonObject));

它将在控制台中为您的对象打印值
