在Meter框架中执行jmx脚本时，在Jmeter中使用$ {__ UUID（）}函数的用户参数预处理程序不起作用

问题描述 投票：0回答：1

我正在使用用户参数预处理器在脚本中调用$ {__ UUID（）}函数以生成UUID。UserParameter

此$ {__ UUID（）}工作正常，当我从Jmeter gui或Jmeter non gui / cmd执行jmx脚本时，会生成UUID。

Jmeter日志：2020-04-14 15：24：44,173信息o.a.j.u.BeanShellTestElement：UUID ========> 3c8114da-1657-4e99-85bd-49081be0172b

但是，每当我尝试从我的JMeter-Maven框架执行相同的jmx脚本时，它只会在使用此函数$ {__ UUID（）}的请求中失败。

Jmeter日志：2020-04-14 15：03：05,695信息o.a.j.u.BeanShellTestElement：UUID ========> $ {__ UUID（）}

根据我的理解，根据日志，在从JMeter-Maven框架执行脚本时，它无法使用功能$ {__ UUID（）}生成UUID。

使用功能$ {__ UUID（）}为请求生成的HTML报告中的错误：非HTTP响应代码：java.net.URISyntaxException /非HTTP响应消息：索引43处查询中的非法字符

这是我的pom.xml文件：

我无法重现您的问题，但是我可以在您的测试中看到其他几个问题：

  1. __UUID() function的正确语法为：

    ${__UUID}

    如果不确定正确的语法，最好使用Functions Helper Dialog，有关更多详细信息，请查看Apache JMeter Functions - An Introduction文章。

  2. 此<dependencies>块不是必需的，JMeter Maven plugin将下载JMeter本身的相关版本
  3. 根据JMeter最佳实践you should always be using the latest version of JMeter，因此请考虑将JMeter插件版本更改为3.0.0
  4. Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting。此外，您不应将JMeter函数或变量内联到脚本中，而应使用vars.get("sample_id")代替，其中vars代表JMeterVariables类实例
