实际工作中用到的一些场景:
- 提取某个特定的值
- 提取多个值
- 按条件取值
- 阵列取值(返回所有元素的列表/数组)
- 提取多个值
Jsonpath提取器需要另外安装
使用方法:
Json Path提取器应放在HTTP Sampler下。可设置的参数有:
接下来用一个实际案例来演示Json提取的一些用法:
示例:有如下json

Jsonpath | 结果 |
---|---|
$.data.total | 10 |
$..total | 10 |
$..items[1].userId | 1268082752079560705 |
$..friendId
$..[*].friendId
$.data.items[*].friendId
三种写法都可以,结果为:
Result[0]=1267735865761759234
Result[1]=1267735866185383938
Result[2]=1267735867363983362
Result[3]=1267735867825356802
Result[4]=1267735864650268673
Result[5]=1267735865363300353
Result[6]=1267735866688700417
Result[7]=1267735867003273217
Result[8]=1267735868232204289
Result[9]=1267735868571942913
注意:
使用时,需要用下标读取,如${friend_id_1}、${friend_id_2}........
特别说明一下,如果想要获取返回元素的数量,可以用${friend_id_matchNr}
也可以使用foreach控制器循环读取,这里不再描述。
有时候只需要提取某个特定条件下的参数,比如现在想要提取创建时间为1591169490879的friendId
$.data.items[?(@.createTime ==1591169490879)].friendId
提取任何节点的某个key的值,比如提取friendId
$..friendId
结果为:
friend_all_1=1267735865761759234
friend_all_10=1267735868571942913
friend_all_2=1267735866185383938
friend_all_3=1267735867363983362
friend_all_4=1267735867825356802
friend_all_5=1267735864650268673
friend_all_6=1267735865363300353
friend_all_7=1267735866688700417
friend_all_8=1267735867003273217
friend_all_9=1267735868232204289
friend_all_ALL=1267735865761759234,1267735866185383938,1267735867363983362,1267735867825356802,1267735864650268673,1267735865363300353,1267735866688700417,1267735867003273217,1267735868232204289,1267735868571942913
friend_all_matchNr=10
_ALL下标是将所有元素组成一个list,像后续接口有时候参数是以数组形式来传参,这个函数就很有用,如果需要返回此函数,需要在json提取器中,勾选Compute concatenation var
json表达式:
$..[‘msg‘,‘friendId‘]
返回的变量如下:
two_1={"msg":"你好,我仰慕你的才华!","friendId":1267735865761759234}
two_10={"msg":"你好,我仰慕你的才华!","friendId":1267735868571942913}
