jmeter使用正则表达式匹配多个中的响应结果

一、背景：

二、例如：

三、接口响应的所有结果：

四、正则表达式的写法：

五、调试的时候添加一个Debug PostProcessor 调试器

六、在Debug PostProcessor中可以查看到获取的参数结果

七、引用方式：${testValues_g1} 和 ${testValues_g2}

八、这里还有个小技巧：

九、匹配数字的含义：

一、背景：

同一个正则表达式匹配多个响应结果值，之前都是添加多个正则表达式，一个一个去获取需要的值，比较麻烦；今天尝试了一下用一个正则表达式获取响应中所有需要的值，使用这种方式也能够获取多个结果中指定的值，完美省事！

二、例如：

我要获取如下响应报文中首次出现的两个值（barnType 和 trainScheduleBarnId 的值）目标是：{"available":0,"barnNo":"01","barnType":"STX1","recommend":0,"spaceStatus":"FULL","trainScheduleBarnId":3271}

三、接口响应的所有结果：

{"content":{"barns":[{"available":0,"barnNo":"01","barnType":"STX1","recommend":0,"spaceStatus":"FULL","trainScheduleBarnId":3271},{"available":1,"barnNo":"02","barnType":"STX2","recommend":1,"spaceStatus":"EMPTY","trainScheduleBarnId":3272},{"available":0,"barnNo":"03","barnType":"STX3","recommend":0,"spaceStatus":"EMPTY","trainScheduleBarnId":3273},{"available":0,"barnNo":"04","barnType":"STX4","recommend":0,"spaceStatus":"EMPTY","trainScheduleBarnId":3274},{"available":1,"barnNo":"05","barnType":"STX1","recommend":0,"spaceStatus":"EMPTY","trainScheduleBarnId":3275},{"available":1,"barnNo":"06","barnType":"STX2","recommend":0,"spaceStatus":"EMPTY","trainScheduleBarnId":3276},{"available":0,"barnNo":"07","barnType":"STX3","recommend":0,"spaceStatus":"EMPTY","trainScheduleBarnId":3277},{"available":0,"barnNo":"08","barnType":"STX4","recommend":0,"spaceStatus":"EMPTY","trainScheduleBarnId":3278}],"count":3,"endStationId":2101,"endStationName":"石家庄","endTime":1525491060000,"id":414,"startStationId":2401,"startStationName":"太原","startTime":1525059060000,"trainNo":"K707"},"errorCode":null,"errorMsg":null,"status":"OK"}
