Java对接开关demo

这是一个Java版本的demo，用于对接开关的API接口，可以控制开关的开和关，还有获取开关的状态数据传输过程使用discuz加解密方法，个人密匙可以自己配置

1.demo文件 

package com.util;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;

import com.alibaba.fastjson.JSON;

public class Demo {
	 public static String KEY = "d0d3d5b5466cc1ee89eb808de9f5672d";//个人密匙
	 public static String MID = "5b53a2d341d78427feafeb4520bf41eb";//设备密匙
	 public static String URL = "https://wx663ca7ac2632b137.vip.aoyacms.com/plugin/aoya/iot/api.php";//接口地址
 	
	
	 public static void main(String[] args) {
		 long t =  System.currentTimeMillis()/1000;//当前时间秒数
		 Map<String, String> info = new HashMap<String, String>();
		 info.put("act", "switch");//操作信息 switch 操作开关，getState获取开关状态
		 String json = JSON.toJSONString(info);
		 String ciphertext = AuthCode.Encode(json,KEY);//json格式操作信息 authcode加密
		 String check = Md5.MD5(t + MID + ciphertext);//md5字符串加密验证
		 ciphertext = ciphertext.replace("+", "%2B");
		 Map<String, String> map = new HashMap<String, String>();
		 map.put("t", String.valueOf(t));
		 map.put("ciphertext", ciphertext);
		 map.put("mid", MID);
		 map.put("check", check);
		 String result = httpPost(URL,map);
		 System.out.println(result);//打印返回信息
         
         
	}
	//post提交方法
	public static String httpPost(String urlStr,Map<String,String> params){
        URL connect;
        StringBuffer data = new StringBuffer();  
        try {  
           connect = new URL(urlStr);  
           HttpURLConnection connection = (HttpURLConnection)connect.openConnection();  
           connection.setRequestMethod("POST");  
           connection.setDoOutput(true); 
           connection.setDoInput(true);
           connection.setUseCaches(false);//post不能使用缓存
           connection.setInstanceFollowRedirects(true);
           connection.setRequestProperty("accept", "*/*");
           connection.setRequestProperty("connection", "Keep-Alive");
           connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
           OutputStreamWriter paramout = new OutputStreamWriter(  
                   connection.getOutputStream(),"UTF-8"); 
           String paramsStr = "";   //拼接Post 请求的参数
           for(String param : params.keySet()){
               paramsStr += "&" + param + "=" + params.get(param);
           }  
           if(!paramsStr.isEmpty()){
               paramsStr = paramsStr.substring(1);
           }
           //paramsStr = URLEncoder.encode(paramsStr, "UTF-8");  //输出%C4%E3%BA%C3
           paramout.write(paramsStr);  
           paramout.flush();  
           BufferedReader reader = new BufferedReader(new InputStreamReader(  
                   connection.getInputStream(), "UTF-8"));  
           String line;              
           while ((line = reader.readLine()) != null) {          
               data.append(line);            
           }  
         
           paramout.close();  
           reader.close();  
       } catch (Exception e) {  
           // TODO Auto-generated catch block  
           e.printStackTrace();  
       }  
       return data.toString();
   }
}

2.加解密用md5类 

package com.util;

import java.security.MessageDigest;

public class Md5 {
	public final static String MD5(String s){ 
		char hexDigits[] = { 
		'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 
		'e', 'f'}; 
		try { 
		byte[] strTemp = s.getBytes(); 
		MessageDigest mdTemp = MessageDigest.getInstance("MD5"); 
		mdTemp.update(strTemp); 
		byte[] md = mdTemp.digest(); 
		int j = md.length; 
		char str[] = new char[j * 2]; 
		int k = 0; 
		for (int i = 0; i < j; i++) { 
		byte byte0 = md[i]; 
		str[k++] = hexDigits[byte0 >>> 4 & 0xf]; 
		str[k++] = hexDigits[byte0 & 0xf]; 
		} 
		return new String(str); 
		} 
		catch (Exception e){ 
		return null; 
		} 
	}
}

3.加解密用Base64类 

package com.util;
/**
 * 
 * JAVA 版的BASE64加密
 * 
 * 标准的Base64加密后的字符串长度可以被4整出,比如:
 * 字符		加密后
 * a		YQ==
 * aa		YWE=
 * aaa		YWFh
 * aaab		YWFhYg==
 * aaabb	YWFhYmI=
 * aaabbb	YWFhYmJi
 * 
 * 一旦加密后的字符能被4整除，就用"="来补充
 * 
 * 本例是在网上找的，原本是标准的，遵照RFC2045～RFC2049规范。
 * 
 * PHP版的BASE64可以解密标准的BASE64密文，也可以解密不带后边"="的密文，为了能解密PHP的BASE64和AuthCode加密。
 * （PHP的AuthCode中也用到了BASE64）我将本类做了修改，使之也可以解密不带"="的BASE64密文。
 * 原理很简单，将密文对4取模（"密文"%4），看差即为就补几个"="，然后就得到一个标准的BASE64密文并解之。
 * 
 * 
 * 
 */

import java.io.UnsupportedEncodingException;

    public static byte[] decode(String str) throws UnsupportedEncodingException {
