Jmeter json和正在提取及斷言
一、提取所需要斷言的內容：
響應數據如下：加入需要提取userid為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": "驗證碼錯誤", 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-后置處理器-添加JSON Extracror（這里面需要稍微學習下json path espressions的語法了）--得到id的值90
自己看這個網址學習吧：http://goessner.net/articles/JsonPath/
2、也可以使用正則表達式提取
"userId":(.+?),
3.關聯
下一個請求，使用提取的參數: ${userid_1} 或{userid_2}
二、斷言提取出來的值
sample-斷言-添加json assert
三、json path espressions的語法學習
$：跟對象\元素
@：當前對象\元素
？（）：應用過濾器（腳本）表達式
還是自己練習吧。。。。
