通过azkaban的API链接azkaban服务器，并创建工作流

首先创建一个httpUtil类，方便访问网页：

package com.jh.azkaban;

import java.io.*;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

/**
 * 模拟浏览器的功能
 * 1.测试请求百度服务器
 * */
public class httpUtl
{
    public static void main(String[] args)
    {
        httpUtl httpUtl = new httpUtl();
        String requestUrl = "http://www.teabig.com/train-web-head/head/users/usersUpdate.htm#top";
        Map<String,String> heardmap = new HashMap<>();
        heardmap.put("User-Agent","Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36");//这里添加的请求头信息是模仿浏览器真实访问的情景--浏览器怎么访问代码就这么访问
        Map<String,String> parammap = new HashMap<>();
        /*请求服务器*/
//        String s = httpUtl.methodGet(requestUrl, heardmap, parammap);
        String s = httpUtl.methodPost(requestUrl, heardmap, parammap);                     
        System.out.println("响应=====》"+s);
    }

    /**

    public  String methodGet(String requestUrl, Map<String,String> heardmap,Map<String,String> paramsmap)
    {
        System.out.println("=========ceshi========methodGet======");
        StringBuffer sb = new StringBuffer();
        try {
            URL url = new URL(requestUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            /*请求头配置*/
            for (Map.Entry<String, String> header : heardmap.entrySet()) {
                /*将传入的请求体的参数传入请求头的配置中*/

            }

                sb.append(line+"

            }

            reader.close();
        } catch (Exception e) {


            e.printStackTrace();
        }

        return sb.toString();
    }
    public  String methodPost(String requestUrl, Map<String,String> heardmap,Map<String,String> paramsmap)
    {
        System.out.println("=========ceshi========methodPost======");
        StringBuffer sb = new StringBuffer();
        BufferedReader reader = null;
        BufferedWriter Writer = null;
        try {
            URL url = new URL(requestUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            /*请求头配置*/
            for (Map.Entry<String, String> header : heardmap.entrySet()) {
                /*将传入的请求体的参数传入请求头的配置中*/
                String key = header.getKey();
                String value = header.getValue();
                connection.setRequestProperty(key,value);//请求头的配置
            }

            Iterator<Map.Entry<String, String>> iterator = paramsmap.entrySet().iterator();
            while (iterator.hasNext())
            {
                Map.Entry<String, String> next = iterator.next();
                String key = next.getKey() + "";
                String value = next.getValue() + "";

            }

            /*请求头--get*/

            OutputStream os = connection.getOutputStream();
            Writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));

            StringBuffer sb1 = new StringBuffer();
            Set<Map.Entry<String, String>> paramsSet = paramsmap.entrySet();
            for (Map.Entry<String, String> paramsEntry : paramsSet)
            {

                String value = paramsEntry.getValue();
                sb1.append(key+"="+value+"&");

            }
//            System.out.println("===params=>"+sb1);
            Writer.write(sb1.toString());//将请求体发送到服务器

            Writer.flush();
//            Writer.close();
            InputStream is = connection.getInputStream();
            reader = new BufferedReader(new InputStreamReader(is,"UTF-8"));

            } catch (IOException e) {
                e.printStackTrace();
            }
            try {
                reader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        return sb.toString();
    }

}

链接百度服务器测试是否可以链接

接下来创建一个链接azkaban的工具类：

package com.jh.azkaban;


import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.JSONPObject;

import java.util.HashMap;
import java.util.Map;

public class AzkabanApi_Util
{
    private String reqstr = "http://node7-2:8081";//请求网址
    private httpUtl httpUtl = new httpUtl();

    /**
     *
     * @param username
     * @param password
     * @return
     */
    public JSONObject login(String username, String password)
    {
        Map<String,String> heardmap = new HashMap<>();
        heardmap.put("User-Agent","Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36");
        heardmap.put("Content-Type","application/x-www-form-urlencoded");
        Map<String,String> parammap = new HashMap<>();
        parammap.put("action","login");
        parammap.put("username",username);
        parammap.put("password",password);
        String result = httpUtl.methodPost(reqstr, heardmap, parammap);
        JSONObject parse = (JSONObject) JSON.parse(result);
        return parse;
    }
    public JSONObject create(String sessionid, String name, String description)
    {
        reqstr = reqstr + "/manager";
        Map<String,String> heardmap = new HashMap<>();
        heardmap.put("User-Agent","Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36");
        heardmap.put("Content-Type","application/x-www-form-urlencoded");

        Map<String,String> parammap = new HashMap<>();
        parammap.put("action","create");
        parammap.put("session.id",sessionid);
        parammap.put("name",name);
        parammap.put("description",description);

        String result = httpUtl.methodPost(reqstr, heardmap, parammap);

        JSONObject parse = (JSONObject) JSON.parse(result);
        return parse;
    }
}

创建main方法链接并创建工作流：

package com.jh.azkaban;

import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.JSONPObject;

//import com.alibaba.fastjson.JSONObject;
/**
 * 链接azkaban的API
 * */
public class my_azkaban
{
//    private
    public static void main(String[] args)
    {
        //获取azkaban对象
        AzkabanApi_Util azkabanApi = new AzkabanApi_Util();
        String user = "azkaban";
        String pwd = "azkaban";
//先登录服务器，获取sessionId
        JSONObject jsonObjectstr = azkabanApi.login(user, pwd);
//        jsonpObjectstr.getFunction("status");
        if (jsonObjectstr != null && "success".equalsIgnoreCase(jsonObjectstr.getString("status")) )
        {
            String sessionid = jsonObjectstr.getString("session.id");
            System.out.println(sessionid);

            String name = "my_flow04";
            String describe = "my_flow04";
//通过获取的sessionId，链接并创建工作路流
            JSONObject jsonObject = azkabanApi.create(sessionid, name, describe);
            System.out.println(jsonObject);


        }

    }
}

这样，一个简单的azkaban--API链接就搞定了！！
