jmeter-如何使用从另一个请求的主体数据中的响应中提取的值 [英] jmeter - how to use extracted value from response in Body Data of another request

问题描述

我正在尝试在另一个请求的正文数据"中使用提取的值.我使用如下所示的JSON Path Extractor提取了值

I'm trying to use the extracted value in Body Data of another request. I extracted the value using JSON Path Extractor like below

值是从以下响应中提取的

value is extracted from the below response

我在Body数据中这样使用它

I used it like this in Body data

  {
    "TransactionId": ${transactionId},
    "Cancelled": false
  }

但这在 JMeter 中不起作用，它显示transactionId为["223"]. 我希望只有223

but this is not working in JMeter it shows the transactionId as ["223"]. I want it to be only 223

推荐答案

我们可以通过不同的方式来做到这一点，但是我更喜欢使用"Jmeter"功能(最好避免使用插件). 对于源git 链接

We can do this in different ways, but I prefer to use "Jmeter" functionality (better to avoid plugins). For source git link

1. Using "Regular Expression Extractor" post processor.
2. Using "JSON Path PostProcessor" post processor.

1. 正则表达式提取器":正则表达式提取器不是最好的功能.

1. "Regular Expression Extractor": Regular Expression Extractor is no of the best functionality.

Regular Expression: "transactionId":"(.+?)" Template: $1$ Match Number: 1

Regular Expression: "transactionId":"(.+?)" Template: $1$ Match Number: 1

2."JSON Path PostProcessor":我从没使用过此后处理器，它也很好.下面是表达式

2."JSON Path PostProcessor": I never used this post processor, it's also good. Below is the expression

JSON path Expression : $.transactionId Match Numbers: 1

JSON path Expression : $.transactionId Match Numbers: 1
