Jmeter json和正在提取及断言

Jmeter  json和正在提取及断言

一、提取所需要断言的内容：

响应数据如下：加入需要提取userid为10477的值

 {
     "pub": {
         "status": ,
         "userId": "",
         "apiVersion": "3.9.4.3004",
         "subPline": "",
         "clientAgent": "svnVer_1907021457",
         "channelCode": "AOT1001757",
         "appCode": "f002",
         "model": "ALP-AL00",
         "imsi": "dz_1562222817068",
         "imei": "dz_1562222817068",
         "screen": "720x1206",
         "os": "android28",
         "pname": "com.ishugui12343",
         "apn": "wifi",
         "ip": "192.168.103.113",
         "province": "北京市",
         "city": "北京"
     },
     "pri": {
         "result": "",
         "tips": "验证码错误",
         "account": [
             {
                 "coverWap": "",
                 "appid": "PHONE_NUM_VERIFY",
                 "nickname": "",
                 "id": "",
                 "key": "PHONE_NUM_VERIFY"
             }
         ]
     }
 }

1、sample添加-后置处理器-添加JSON Extracror（这里面需要稍微学习下json path espressions的语法了）--得到id的值90

自己看这个网址学习吧：http://goessner.net/articles/JsonPath/

2、也可以使用正则表达式提取

"userId":(.+?),

3.关联

下一个请求，使用提取的参数: ${userid_1} 或{userid_2}

二、断言提取出来的值

sample-断言-添加json assert

三、json path espressions的语法学习

$：跟对象\元素

@：当前对象\元素

？（）：应用过滤器（脚本）表达式

还是自己练习吧。。。。
