JMeter JSON Extractor，提取字符串中一个键的所有值 [英] JMeter JSON Extractor, extract all values of one key in a string

问题描述

使用 Apache JMeter ver 3.2 r1790745(最新版)测试 JSON Web 服务，响应如下:

[ {身份证":3，"描述": "返回",名称":返回"}, {身份证":1，描述":正面"，名称":前面"}, {身份证":6，"描述": "左",名称":左"}]

想在JSON Extractor中解析上面的响应以获取一个字符串中的所有id，例如

3,1,6

我的 JSON Path 表达式是这样的:

$..id

但我只得到了第一个 id，即 3，结果与 $.[0].id 相同在 BeanShell PostProcessor 中检查结果.如果我去

您将获得所需的值 ${foo_ALL}

<小时>

我不认为使用 Beanshell 是检查 JMeter 变量值的最佳方法，今后我建议使用 调试采样器，请参阅如何调试您的 Apache JMeter 脚本以获取更多详细信息.

Using Apache JMeter ver 3.2 r1790745 (the latest) to test a JSON Web Service, the response is like:

[ {
   "id" : 3,
   "description" : "Back",
   "name" : "back"
}, {
   "id" : 1,
   "description" : "Front",
   "name" : "front"
}, {
   "id" : 6,
   "description" : "Left",
   "name" : "left"
}]

Want to parse the above response to get all ids in one string in JSON Extractor, like

3,1,6

My JSON Path expressions is like this:

$..id

But I got only the 1st id which is 3, the same result as $.[0].id Checking the result in a BeanShell PostProcessor. If I go to http://jsonpath.com/ $..id does give me

[
  3,
  1,
  6
]

解决方案

If you configure your JSON Extractor like:

You will get the required value as ${foo_ALL}

I don't think using Beanshell is the best way to check JMeter Variable value, going forward I would suggest using Debug Sampler instead, see How to Debug your Apache JMeter Script for more details.
