JSR223 预处理器代码应该运行仅用于 HTTP 采样器

Question

我有一个 JSR223 预处理器 代码如下：

String method = sampler.getMethod();

JMeter 测试计划如下：

      - JSR223 Pre Processor
      - HTTP Sampler
      - JSR223 Sampler / Any other sampler apart from HTTP

由于 JSR223 PreProcessor 将应用于层次结构中的所有采样器，因此除了 HTTP 采样器 之外，所有采样器都会出现以下错误.

我希望我的 JSR223 代码仅用于 HTTP Sampler

运行

Answer 1

检查之前是否有 HTTP 采样器：

if (sampler instanceof org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase) { 
   String method = sampler.getMethod(); 
}

JMeter

中的类似代码

if (testElement instanceof HTTPSamplerBase) {

如何将 JSR223 预处理器移动为 HTTP 请求采样器的子级？

在这种情况下，它的范围将仅限于父采样器，并且不会在每个采样器之前执行。
