java接口自动化测试：测试websocket接口（带cookie认证，发送json数据）

1.pom中引入依赖

            org.java-websocket
            Java-WebSocket
            1.3.4

2.测试代码

import org.apache.commons.io.FileUtils;
import org.java_websocket.client.WebSocketClient;
import org.java_websocket.drafts.Draft;
import org.java_websocket.framing.Framedata;
import org.java_websocket.handshake.ServerHandshake;
import org.java_websocket.drafts.Draft_6455;

import java.io.File;
import java.net.URI;
import java.util.HashMap;
import java.util.Map;

public class Testwebsocket extends WebSocketClient {
    
    //不带cookie认证
    public Testwebsocket(URI serverUri , Draft draft ) {
        super( serverUri, draft );
    }

    public Testwebsocket( URI serverURI ) {
        super( serverURI );
    }

    //带cookie认证时，用map
    public Testwebsocket(URI serverUri, Draft draft, Map headers, int timeout) {
        super( serverUri, draft, headers, timeout );
    }


    @Override
    public void onOpen( ServerHandshake handshakedata ) {
        System.out.println( "开流--opened connection" );
    }

    @Override
    public void onMessage( String message ) {
        System.out.println( "接收--received: " + message );
    }

    @Override
    public void onFragment( Framedata fragment ) {
        System.out.println( "片段--received fragment: " + new String( fragment.getPayloadData().array() ) );
    }

    @Override
    public void onClose( int code, String reason, boolean remote ) {
        System.out.println( "关流--Connection closed by " + ( remote ? "remote peer" : "us" ) );
    }

    @Override
    public void onError( Exception ex ) {
        ex.printStackTrace();

    }

    public static void main(String[] args) {
        try {
            //用来发送的json数据，我这里将它放在一个文档里读取
            String input = FileUtils.readFileToString(new File("src/main/resources/test.json"), "UTF-8");
            net.sf.json.JSONObject jsonObject = net.sf.json.JSONObject.fromObject(input);

            //需要cookie时，用map存储cookie
            //Map headers = new HashMap();
            //headers.put("Cookie", "sso.xx.com=XX.6069xx988696471cbbc074caff1f8308;");

            //使用cookie时的实例，ws地址换成自己的
            //Testwebsocket c = new Testwebsocket( new URI( "ws://test.xx.com:3000/dashboard/web/test/" ), new Draft_6455(), headers,  10000);

            //没有cookie时
            Testwebsocket c = new Testwebsocket( new URI( "ws://test.xx.com:3000/dashboard/web/test/" ), new Draft_6455());

            c.connect();

            while(!c.getReadyState().equals(READYSTATE.OPEN)){
                Thread.sleep(10);
                System.out.println("连接还没有打开！");
            }
            System.out.println("连接打开了！");
            //c.send("测试");

            c.send(jsonObject.toString());   //发送json数据

            //接收数据中，时间到了手动关闭连接，否则有可能一直接收消息
            Thread.sleep(15000);             
            c.close();    
                 
        } catch (Exception e) {
            e.printStackTrace();
        }
    }


}

3.运行结果

4.踩的坑

一开始用的草案Draft_17，结果报错：org.java_websocket.exceptions.WebsocketNotConnectedException，并提示Draft_17已过时。

于是，使用1.3.4之后版本的Draft_6455。
