JSON提取器

如果返回的数据是JSON格式的,我们可以用JSON提取器来提取需要的字段,这样更简单一点,

 老司机你懂的:https://item.taobao.com/item.htm?id=613711271112

JSON主要运用于返回JSON格式的,格式:$.data[0].id  $.data.xx1。

 提取器要放到http请求下面:

 

 

 

 

 

  • Variable names:保存的变量名,后面使用${Variable names}引用

  • JSON Path  expressions:调试通过的json path表达式

  • Match Numbers:匹配数字(0代表随机,1代表第一个,-1代表所有)

  • Default Values:找不到时默认值,一般设置为NOT FOUND

  • Compute concatenation var(suffix_ALL):是否统计所有,即将匹配到的所有值保存,名为“变量名_ALL”

示例:

请求URL:https://fe-api.zhaopin.com/c/i/sou?pageSize=60&cityId=765&workExperience=-1&education=-1&companyType=-1&employmentType=-1&jobWelfareTag=-1&kw=%E8%BD%AF%E4%BB%B6%E6%B5%8B%E8%AF%95&kt=3

返回的数据格式:

现在我们来提取职位的positionURL字段:

1、在查看结果树中通过JSON Path Tester来调试json path

 

 

2、添加JSON提取器,设置正确的参数,获取第一个positionURL

输出结果:

3、获取所有的positionURL

输出结果:

4、把所有的positionURL放到一个字段中

输出结果:

5、一次性提取多个字段,比如我们要提取第一个职位的jobName;salary;positionURL三个字段

输出结果:

 

 Json Path表达式:

JsonPath

描述

$

根节点

@

当前节点

.or[]

子节点

..

选择所有符合条件的节点

*

所有节点

[]

迭代器标示,如数组下标

[,]

支持迭代器中做多选

[start:end:step]

数组切片运算符

?()

支持过滤操作

()

支持表达式计算
