Problem in JSR223 script JSR223 Sampler, message: javax.script.ScriptException: ReferenceError: "setTimeout" is not defined

我有一个要求，我需要 运行 一个 JS 文件来获取令牌。 JS 文件引用了变量，如“window”、“setTimeout”函数，这些函数在浏览器加载时可用。

但我需要加载这个 Jmeter，并提取令牌。问题是 JSR233 说它没有引用“window”或“setTimeout”函数（否则在浏览器中可用）。

当我 运行 它时，我得到以下错误。有什么方法可以在 Jmeter 中获取这些函数的句柄。

Window对象是与浏览器密切相关的东西，你将无法在JSR223测试元素中使用。

有两种处理方式：

  1. 使用WebDriver Sampler plugin其中：

  2. 在 JSR223 测试元素中复制 JavaScript 文件的逻辑（注意 Groovy language is recommended for scripting), if the script requires some parameters you should be able to get them from the previous response using JMeter's Post-Processors
