问题描述

这里是 PostMan 6.0.10.我试图了解如何更好地编写测试脚本，并在阅读了他们的其他 精湛的文档 我仍然对如何查询 &检查从请求返回的 JSON 响应.

具体来说，给定以下 JavaScript 片段:

pm.test("验证响应payload的内容是否正确", function () {//???});

我需要能够查询响应 JSON 并且:

• 确定响应是单个 JSON 对象还是 JSON 对象数组
• 如果它是一个数组，则确定大小(数组中的元素数)
• 否则，如果它是单个对象，我需要能够查询该对象的特定字段(例如，名为fizzbuzz"的字段)并获取值和 JSON 类型(字符串、数字, bool, null) 的这些字段

场景#1:JSON响应是一个数组

例子:

<代码>[{嘶嘶":嗡嗡声"，富":53},{嘶嘶":博兹"，富":291}]

场景#2:JSON响应是单个对象

例子:

<代码>{嘶嘶":嗡嗡声"，富":293}

知道如何对响应负载执行 JSON 检查吗?

这是基本的，但应该能够获得动态:

pm.test("验证示例一的payload", () => {pm.expect(pm.response.json()[0].fizz).to.equal('buzz')pm.expect(pm.response.json()[0].foo).to.equal(53)pm.expect(pm.response.json()[1].fizz).to.equal('bozz')pm.expect(pm.response.json()[1].foo).to.equal(291)});pm.test("验证示例二的payload", () => {pm.expect(pm.response.json().fizz).to.equal('buzz')pm.expect(pm.response.json().foo).to.equal(293)});

可能值得研究一些基本的 JavaScript 以及如何解析 JSON 对象.p>

PostMan 6.0.10 here. I'm trying to understand how to write test scripts a little better, and after reading their otherwise superb documentation I still have some confusion surrounding how to query & examine the JSON response coming back from requests.

Specifically, given the following snippet of JavaScript:

pm.test("Verify the contents of the response payload are correct", function () {
    // ???
});

I need to be able to query the response JSON and:

• Determine if the response is a single JSON object or an array of JSON objects
• If its an array, determine the size (# of elements in the array)
• Else if its a single object, I need to be able to query that object for specific fields (say, a field called "fizzbuzz") and obtain the values and JSON types (string, number, bool, null) of those fields

Scenario#1:JSONresponseisanarray

Example:

[
    {
        "fizz": "buzz",
        "foo": 53
    },
    {
        "fizz": "bozz",
        "foo": 291
    }
]

Scenario#2:JSONresponseisasingleobject

Example:

{
    "fizz": "buzz",
    "foo": 293
}

Any ideas how this JSON inspection of the response payloads can be performed?

This is basic but should work to get the dynamics:

pm.test("Verify payload of example one",  () => {
    pm.expect(pm.response.json()[0].fizz).to.equal('buzz')
    pm.expect(pm.response.json()[0].foo).to.equal(53)
    pm.expect(pm.response.json()[1].fizz).to.equal('bozz')
    pm.expect(pm.response.json()[1].foo).to.equal(291)
});

pm.test("Verify payload of example two",  () => {
    pm.expect(pm.response.json().fizz).to.equal('buzz')
    pm.expect(pm.response.json().foo).to.equal(293)
});

Might be worth researching some basic JavaScript and how to parse JSON objects.
