Jmeter中【Json提取器】使用方法

添加插件方法

 json 提取器参数介绍

• names of created variables ：接收值的变量名，多个变量时用分号分隔
• json path： json path表达式，也是用分号分隔
• match no：0随机；n取第几个匹配值；-1匹配所有，后续引用用 变量名_N 取第N个值。
• default values： 缺省值，匹配不到值的时候取该值

取响应json里面的第一个id值

$..*

取多个不同字段值

我想同时取出多个不同字段的值

例：

{
    "code": "0",
    "data": {
        "paymentNo": "202106090118460116",
        "pspId": "001",
        "payInfo": "https:\/\/qr.95516.com\/48020000\/65532106091201847132826151"
    },
    "message": "OK"
}

比如：我要取paymentNo、pspId、payInfo的变量值

• 1、各选项均用分号";"隔离
• 2、Default Values必填
