JMeter:如何使用正则表达式提取重复字段的值? [英] JMeter: How to use Regular Expression to extract the value of a duplicate field?

问题描述

我有以下响应正文JSON:

I have the following Response Body JSON:

{
    "address": [
    {
        "id": "1234"
    }
    ],
    "id": "d1a4f010-48d9-434b-9b3a-2d2b12f5e38c"
}

我正在尝试提取 second "id"字段的值，即

I am trying to extract the value of the the second "id" field, i.e.

"id": "d1a4f010-48d9-434b-9b3a-2d2b12f5e38c"

我在JMeter中使用以下正则表达式: 正则表达式:"id":(.+?)"

I use this Regular Expression in JMeter: Regular Expression: "id":"(.+?)"

运行测试时，它将返回"1234"而不是GUID.如何更改我的正则表达式，使其返回GUID?

When I run my test, it returns "1234" instead of the guid. How can I change my Regular Expression so that it returns the guid?

推荐答案

您可以使用惰性正则表达式直接查找guid，而不用查找"id"

You can use a lazy regex to find the guid directly instead of finding "id"

类似这样的内容:([0-9a-z-]{36}).*?

如果不确定如何创建正则表达式，只需使用在线正则表达式制造商即可.

If you are not sure how to create the regex, just use an online regex maker.
