运行 HttpSampler 的 JMeter API 代码不起作用 [英] JMeter API Code to run HttpSampler doesnt work

问题描述

这是我根据我发现的一些示例编写的使用 JMeter API 运行 HTTPRequest 的类.

This is the class that I have written to run HTTPRequest using JMeter API based on some samples I found.

import org.apache.jmeter.control.LoopController;
import org.apache.jmeter.engine.StandardJMeterEngine;
//import org.apache.jmeter.protocol.java.sampler.JUnitSampler;
import org.apache.jmeter.protocol.http.sampler.*;
import org.apache.jmeter.testelement.TestElement;
import org.apache.jmeter.testelement.TestPlan;
import org.apache.jmeter.threads.SetupThreadGroup;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;

public class Jmeter {


public static void main(String[] args){

    // Engine
    StandardJMeterEngine jm = new StandardJMeterEngine();
    // jmeter.properties
    JMeterUtils.loadJMeterProperties("D:/apache-jmeter-2.13/bin/jmeter.properties");

    HashTree hashTree = new HashTree();     

    // HTTP Sampler
    HTTPSampler httpSampler = new HTTPSampler();
    httpSampler.setDomain("www.google.com");
    httpSampler.setPort(80);
    httpSampler.setPath("/");
    httpSampler.setMethod("GET");

    // Loop Controller
    TestElement loopCtrl = new LoopController();
    ((LoopController)loopCtrl).setLoops(1);
    ((LoopController)loopCtrl).addTestElement(httpSampler);
    ((LoopController)loopCtrl).setFirst(true);

    // Thread Group
    SetupThreadGroup threadGroup = new SetupThreadGroup();
    threadGroup.setNumThreads(1);
    threadGroup.setRampUp(1);
    threadGroup.setSamplerController((LoopController)loopCtrl);

    // Test plan
    TestPlan testPlan = new TestPlan("MY TEST PLAN");

    hashTree.add("testPlan", testPlan);
    hashTree.add("threadGroup", threadGroup);
    hashTree.add("httpSampler", httpSampler);       

    jm.configure(hashTree);
    System.out.println(jm.isActive());
    jm.run();
}
}

我正在 Eclipse 中尝试相同的代码，但收到以下警告和错误.有人能帮我解决吗?

I'm trying the same code in Eclipse but I'm getting the following warnings and errors. Can anyone help me resolve it?

提前致谢！

根据您的建议.我已经用循环控制器更新了代码.请在下面找到 JMeter 日志和 Eclipse 输出.

Based on your suggestion. I have updated the code with loop controller. Please find the JMeter Log and Eclipse Output below.

请帮我解决这个问题.谢谢！

Please help me resolve this issue.Thanks!

推荐答案

我相信你需要添加以下行:

I believe that you need to add the following line:

hashTree.add("loopController", loopCtrl);

before jm.configure(hashTree);

如果它没有帮助 - 用 Eclipse 输出和 jmeter.log 文件内容更新你的问题(应该出现在你的项目根目录中)

If it doesn't help - update your question with Eclipse output and jmeter.log file contents (should appear in your project root)

请参阅以下材料以供参考:

See the following material for reference:
