JMeter 3.3：无法从文件中读取变量 - 类型化变量声明：Class：在命名空间中找不到 Wini

Question

让我介绍一下背景。

如您所见，定义了两个变量，它们使用以下值指向两个不同的 *.ini 文件：

${__BeanShell(import org.apache.jmeter.services.FileServer; FileServer.getFileServer().getBaseDir();)}${__BeanShell(File.separator,)}Settings.ini

对于变量：SettingsFile

使用分步调试器，我可以确认文件路径是正确的。现在，有趣的部分。我几乎没有从文件中读取值的“用户定义变量”。

JMeter 无法读取此变量的值并为每个变量抛出以下错误：

使用（例如）：用于变量 accountNumber

Settings.ini的样子（以accountNumber为例）：

[General]
    ;account number used for testing
    accountNumber = 989899773
    ;BadAccountNumber = 12314500
    BadAccountNumber = 989899773

关于如何消除此错误的任何想法？我不明白为什么在文件路径正确的情况下我无法读取每个变量的值。

PS: 我在“查看结果树”中没有得到任何结果。所有测试都是使用文件中变量的简单 HTTP 请求。

这是由于缺少 ini4j library, you need to download the .jar, put it somewhere to JMeter Classpath 并重新启动 JMeter 以获取 .jar。

还要注意 starting from JMeter 3.1 it is recommended to use JSR223 Test Elements and __groovy() function for any form of scripting in JMeter. So consider to moving to Groovy on next available opportunity. More information: Apache Groovy - Why and How You Should Use It
