postman高级用法--断言（Response body:JSON value check）

今天在小伙伴的分享中遇到了个问题，postman中的高级用法--断言，因为我们返回的json千奇百怪，所以呢，需要我们按照js的用法，来找出具体到json最内层的字段。

废话不说了，直接搞：

我的接口返回的json长成这个鬼样子。

{
    "code": 0,
    "message": "success",
    "data": {
        "goods_list": [
            {
                "goods_id": "JD_60436279224",
                "goods_source": "web",

            },
            {
                "goods_id": "JD_2496994",
                "goods_source": "web",
                "goods_url": "https://homed-inhouse.bytedance.net/growth/product-details/?uniq_pid=JD_2496994&invoke_source=0",

                "goods_price": "¥18"
            },
            {
                "goods_id": "JD_56799618502",
                "goods_source": "web",
                "goods_url": "https://homed-inhouse.bytedance.net/growth/product-details/?uniq_pid=JD_56799618502&invoke_source=0",

                "goods_title": "【京东新品】数字油画油彩画动漫风景人物填色画手工数字画填充压装饰画B01 A558 40*50彩色画板(厚框)  画板+颜料+画笔+无",

            },
            {
                "goods_id": "JD_51542690471",
                "goods_source": "web",
                "goods_url": "https://homed-inhouse.bytedance.net/growth/product-details/?uniq_pid=JD_51542690471&invoke_source=0",
                "goods_avatar": "https://img13.360buyimg.com/img/jfs/t1/46814/4/4055/290947/5d1c63c9E8aee4423/612a4da6e62a1727.jpg",
                "goods_title": "简微娜 床笠单件棉全棉加厚席梦思床垫保护套加密裸睡1.5 1.8m床套床罩 羽彩纷飞-豆沙 120cmx200cm(加厚款升级)",
                "goods_price": "¥138"
            }
        ],
        "recommend_rectangle": null,
        "request_rectangle": {
            "left_top_x_percent": 0.41,
            "left_top_y_percent": 0.41,
            "right_bottom_x_percent": 0.59,
            "right_bottom_y_percent": 0.59
        },
        "log_id": "201912261839170100170221671000621A"
    }
}

那么postman上面如何搞呢。

下面我想取出json中最内层的goods_id进行断言

1、取到data

pm.test("Your test name", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.data).to.eql("字符串");
});

2、取到上面json的goods_list

pm.test("Your test name", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.data.goods_list).to.eql("字符串");
});

3、取到上面json的第一个goods_id

pm.test("Your test name", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.data.goods_list[0].goods_id).to.eql("JD_60436279224");
});

然后我就可以成功了。。。
