JMeter:如何知道为什么我在 JMeter 中的正则表达式提取器没有提取数据

问题描述

我想知道为什么JMeter中的正则表达式提取器在参数化后不提取数据.响应消息:内部服务器错误

添加的表达式是:

1. name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="(.+?)"

2. name="__VIEWSTATE" id="__VIEWSTATE" value="(.+?)"

POST 数据:__VIEWSTATE=%24%7BviewState%7D&__EVENTVALIDATION=%24%7BeventValidation%7D&txtUserID=1001201&txtPWD=CFL&BtnSubmit=Submit&hdnE=5&hdnN=323&7>hdnD

解决方案

您的正则表达式可能有误.

要调试它，请运行您的测试，然后使用查看结果树"并选择正则表达式测试器":

然后您可以测试您的正则表达式，看看会发生什么.

由于我没有包含 2 个标记的响应内容，我只能猜测正则表达式应该是:

• name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="([^"]+?)" ，参见 https://regex101.com/r/aG1gX2/1

• name="__VIEWSTATE" id="__VIEWSTATE" value="([^"]+?)" ，见 https://regex101.com/r/iM5cZ3/1

I would like to know why regular expression extractor in JMeter is not extracting the data after parameterization. Response message: Internal Server Error

Expression added are:

1. name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="(.+?)"

2. name="__VIEWSTATE" id="__VIEWSTATE" value="(.+?)"

POST data:
__VIEWSTATE=%24%7BviewState%7D&__EVENTVALIDATION=%24%7BeventValidation%7D&txtUserID=1001201&txtPWD=CFL&BtnSubmit=Submit&hdnE=5&hdnN=323&hdnD=173

解决方案

Your regexp is probably wrong.

To debug it, run your test then use View Results Tree and select Regexp Tester:

You can then test your regexps and see what happens.

As I don't have the response content that contains the 2 tokens, I can only guess that regexp should be :

• name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="([^"]+?)" , see https://regex101.com/r/aG1gX2/1

• name="__VIEWSTATE" id="__VIEWSTATE" value="([^"]+?)" , see https://regex101.com/r/iM5cZ3/1
