如何从java代码而不是从JMeterGUI设置BeanShellPostProcessor脚本？

我有一个需求，我需要添加

BeanShellPostProcessor

，最好用java编程

下面是将

BeanShellPostProcessor

添加到

JMX

的示例代码，它正在工作。但我不想硬编码脚本（请参阅下面的代码），脚本将针对每个API测试进行更改。 如何以编程方式编写

beanshell

脚本

String script = "if (prev.getResponseCode().equals(401) == true) { prev.setResponseOK();}";

        BeanShellPostProcessor bspp = new BeanShellPostProcessor();
        bspp.setProperty(TestElement.TEST_CLASS, BeanShellPostProcessor.class.getName());
        bspp.setProperty(TestElement.GUI_CLASS, TestBeanGUI.class.getName());
        bspp.setName("BeanShell PostProcessor");
        bspp.setProperty("resetInterpreter", false);
        bspp.setProperty("enabled", true);
        bspp.setProperty("script", script );

        HTTPSampleProxyHashTree.add(bspp);

请考虑迁移到相反的位置。<李>

您可以通过从加载脚本使其成为动态的，即。相关代码类似于：

String script = JMeterUtils.getPropDefault("my.script",
        "if (prev.getResponseCode().equals(401) == true) { prev.setResponseOK();}");
JSR223PostProcessor jsr223PostProcessor = new JSR223PostProcessor();
jsr223PostProcessor.setName("JSR223 PostProcessor");
jsr223PostProcessor.setProperty("cacheKey", "true");
jsr223PostProcessor.setProperty("script", script);
jsr223PostProcessor.setProperty("scriptLanguage", "groovy");
jsr223PostProcessor.setProperty(TestElement.TEST_CLASS, JSR223PostProcessor.class.getName());
jsr223PostProcessor.setProperty(TestElement.GUI_CLASS, TestBeanGUI.class.getName());

如果设置了

my.script

属性，JMeter将使用它的值作为Groovy脚本，如果没有设置，它将继续使用默认的硬编码值

您甚至不需要编写脚本，添加一个勾选了

ignorestatus

的框就足够了

您希望它如何是动态的？是否有任何生成的方法来创建示例比较脚本。或者我们可以访问java代码中的beanshell预定义变量。这里我在字符串中声明“prev.getResponseCode（）”。可以使用beanshell方法完成吗？非常感谢您的帮助。我正在使用响应断言。现在我不需要编写任何脚本，而是使用ResponseAservation类的内置方法。
