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
1 { 2 "pub": { 3 "status": 0, 4 "userId": "10477", 5 "apiVersion": "3.9.4.3004", 6 "subPline": "2", 7 "clientAgent": "svnVer_1907021457", 8 "channelCode": "AOT1001757", 9 "appCode": "f002", 10 "model": "ALP-AL00", 11 "imsi": "dz_1562222817068", 12 "imei": "dz_1562222817068", 13 "screen": "720x1206", 14 "os": "android28", 15 "pname": "com.ishugui12343", 16 "apn": "wifi", 17 "ip": "192.168.103.113", 18 "province": "北京市", 19 "city": "北京" 20 }, 21 "pri": { 22 "result": "0", 23 "tips": "验证码错误", 24 "account": [ 25 { 26 "coverWap": "", 27 "appid": "PHONE_NUM_VERIFY", 28 "nickname": "", 29 "id": "", 30 "key": "PHONE_NUM_VERIFY" 31 } 32 ] 33 } 34 }
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。。。。
