Jmeter对websocket进行测试-编程知识

JMeterWebSocketSampler-1.0.2-SNAPSHOT.jar下载

公司使用websocket比较奇怪，需要带认证信息进行长连接，通过websocket插件是请求失败，如下图，后面通过代码实现随再打包jar包完成websocket测试

本地实现代码如下：

package com.fangdd.socket;import io.socket.client.IO;
import io.socket.client.Socket;
import io.socket.emitter.Emitter;
import java.net.URI;
import java.net.URISyntaxException;
import java.io.IOException;public class SocketIOExample {public static void main(String[] args) throws URISyntaxException, IOException {IO.Options options = new IO.Options();        options.query="tid=wwwww1231&uid=12352547&ticket=mxLqAgCaq7R";Socket socket = IO.socket(URI.create("http://localhost:9092"), options);socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {@Overridepublic void call(Object... args) {System.out.println("connect");// 如果需要发消息参考此代码 连接成功后发送具有body的自定义事件，公司暂不需要注释此代码
//                JSONObject body = new JSONObject();
//                try {
//                    body.put("message", "Hello, Server!");
//                } catch (JSONException e) {
//                    e.printStackTrace();
//                }
//
//                // 发送事件到服务器--需要与开发确认事件(customEvent)
//                socket.emit("customEvent", body);}});socket.on(Socket.EVENT_CONNECT_ERROR, new Emitter.Listener() {@Overridepublic void call(Object... args) {System.out.println("connect_error: " + args[0]);}});socket.on(Socket.EVENT_DISCONNECT, new Emitter.Listener() {@Overridepublic void call(Object... args) {System.out.println("disconnect due to: " + args[0]);}});socket.connect();// 监听服务器返回的自定义事件----需要与开发确认监听事件(messageEvent)socket.on("messageEvent", new Emitter.Listener() {@Overridepublic void call(Object... args) {// 处理服务器返回的数据，如果是json需要数据处理//JSONObject response = (JSONObject) args[0];System.out.println("Server response: " + args[0].toString());}});}}

显示如下：

开发代码打包到lib/ext目录，通过Jmeter对本地方法进行测试，具体实现代码如下：

底层实现代码：


import java.net.URI;
import io.socket.client.IO;
import io.socket.client.Socket;
import io.socket.emitter.Emitter;public class NomalTools {	public static void  IOsocket(String url,String tid) {IO.Options options = new IO.Options();        options.query="tid="+tid+"&uid=12352547&ticket=mxLqA";Socket socket = IO.socket(URI.create(url), options);socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {@Overridepublic void call(Object... args) {System.out.println("connect");}});socket.on(Socket.EVENT_CONNECT_ERROR, new Emitter.Listener() {@Overridepublic void call(Object... args) {System.out.println("connect_error: " + args[0]);}});socket.on(Socket.EVENT_DISCONNECT, new Emitter.Listener() {@Overridepublic void call(Object... args) {System.out.println("disconnect due to: " + args[0]);}});socket.connect();// 监听服务器返回的自定义事件socket.on("messageEvent", new Emitter.Listener() {@Overridepublic void call(Object... args) {// 处理服务器返回的数据
//                JSONObject response = (JSONObject) args[0];System.out.println("Server response: " + args[0].toString());}});//10秒后自动关闭连接
//        try {
//			Thread.sleep(10000);
//			System.out.println("10秒自动关闭连接");
//		} catch (InterruptedException e) {
//			e.printStackTrace();
//		}
//        socket.close();}}

Jmeter封装代码：


import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;
import Common.NomalTools;public class socketTest extends AbstractJavaSamplerClient{private NomalTools nomalTools;private String url;private String tid;private static long start = 0;private static long end = 0;public Arguments getDefaultParameters() {Arguments params = new Arguments();params.addArgument("url", "");params.addArgument("tid", "");return params;}//每个线程测试前执行一次，做一些初始化工作；public void setupTest(JavaSamplerContext arg0) {nomalTools=new  NomalTools();url = arg0.getParameter("url");tid = arg0.getParameter("tid");start = System.currentTimeMillis();}public SampleResult runTest(JavaSamplerContext arg0) {SampleResult sr = new SampleResult();sr.setSamplerData("请求参数num1："+url+"\n请求参数num2："+tid);try {sr.sampleStart();// jmeter 开始统计响应时间标记// 通过下面的操作就可以将被测方法的响应输出到Jmeter的察看结果树中的响应数据里面了。nomalTools.IOsocket(url, tid);            
//             System.out.println(resultData);sr.setSuccessful(true);} catch (Throwable e) {sr.setSuccessful(false);e.printStackTrace();} finally {sr.sampleEnd();// jmeter 结束统计响应时间标记}return sr;}//测试结束时调用；public void teardownTest(JavaSamplerContext arg0) {end = System.currentTimeMillis();// 总体耗时System.err.println("cost time:" + (end - start) + "毫秒");}public static void main(String[] args) {Arguments params = new Arguments(); params.addArgument("url", "http://localhost:9092");//设置参数，并赋予默认值1 params.addArgument("tid", "qwe123");//设置参数，并赋予默认值2JavaSamplerContext arg0 = new JavaSamplerContext(params); socketTest test = new socketTest(); test.setupTest(arg0); test.runTest(arg0);test.teardownTest(arg0); }
}

集成到Jmeter的效果：
