postman之如何实现接⼝测试断⾔json返回值（多层级
json）+判断返回值中包含字符
本节⽬的：使⽤实现接⼝断⾔，取接⼝中的某个字段验证
⽰例接⼝：
备注：接⼝为Get类型（该接⼝为某应⽤搜索接⼝，搜索内容为“号外天下”）
步骤如下：
1. 双击启动postman
2. 请求接⼝
在右侧输⼊接⼝地址如下图，⼤家可以直接点击nd看看该接⼝返回的是什么值
实际接⼝返回如下：

3. 设置断⾔
高二物理知识点
我们不可能写好接⼝之后，每次挨个点击进去查看⼀下是否返回数据正确，因此需要我们设置⼀些判断，判断这个接⼝是否正常运⾏。这个
判断就叫断⾔。postman中的断⾔是在tests中设置，如下图（点击test即进⼊了断⾔设置区）
⼀、断⾔返回的json数据中是否存在“result“字段
1. 点击上图中右⽅红⾊字体“Respon body:contains string"
2. 点击之后，会在tests框中⾃动⽣成⼀串代码如下：
142
"nickname": "⼤庆⾼新区法院",143
"readNum": "1192",144
"title": "号外！号外！驻院律师缘何不收费？",145

3. 修改测试命名以及检测测result字段是否存在
4. 点击nd运⾏接⼝，结果如下：
5.
1.
6. 上图body为接⼝请求返回的参数，点击test results可以查看断⾔结果，红⾊为失败，蓝⾊为断⾔正确⼆、断⾔json返回值中的ur_list下第⼀个结果的nickname值为”号外天下“
1. 点击右⽅红⾊字体：Respon body:Json value check
2. 将系统⽣成的代码修改为：
三、断⾔断⾔json返回值中的article_list下第⼆个结果的nickname值为”百⽶⽣活唐⼭“
tests["Body matches string"] = responBody.has("string_you_want_to_arch");
tests["检测是否返回result 字段"] = responBody.has("result");
1var jsonData = JSON.par(responBody);2tests["检查公众名称"] = jsonData.ur_list[0].nickname === "号外天下"
tests["检查⽂章名称"] = jsonData.article_list[1].nickname === "百⽶⽣活唐⼭"
