java微信公眾號(hào)開發(fā)案例

更新時(shí)間：2016年11月22日 11:43:03 作者：偉雪無痕

這篇文章主要為大家詳細(xì)介紹了java微信公眾號(hào)開發(fā)案例，如何接入公眾號(hào)，訂閱號(hào)怎么樣接收消息,具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

微信公眾號(hào)開發(fā)一般是針對(duì)企業(yè)和組織的，個(gè)人一般只能申請(qǐng)訂閱號(hào)，并且調(diào)用的接口有限，下面我們就來簡(jiǎn)單的描述下接入公眾號(hào)的步驟：

1、首先你需要一個(gè)郵箱在微信公眾號(hào)平臺(tái)進(jìn)行注冊(cè)；
注冊(cè)的方式有訂閱號(hào)、公眾號(hào)、小程序和企業(yè)號(hào)，個(gè)人我們這里只能選擇訂閱號(hào)

2、注冊(cè)完后，我們登錄到公眾號(hào)平臺(tái)--->開發(fā)--->基本配置,這里需要填寫URL和token，URL就是我們使用服務(wù)器的接口；

3、Java Web服務(wù)器程序編譯好且在服務(wù)器上部署可以運(yùn)行的話，可在微信公眾號(hào)進(jìn)行在線接口調(diào)試：

    1）、選擇合適的接口
    2）、系統(tǒng)會(huì)生成該接口的參數(shù)表，您可以直接在文本框內(nèi)填入對(duì)應(yīng)的參數(shù)值（紅色星號(hào)表示該字段必填）
    3）、點(diǎn)擊檢查問題按鈕，即可得到相應(yīng)的調(diào)試信息

eg:獲取access_token的步驟：

   1）、接口類型：基礎(chǔ)支持
   2）、接口列表：獲取access_token接口/token
   3）、填寫相應(yīng)的參數(shù)：grant_type、appid、secret
   4）、點(diǎn)擊檢查問題
   5）、驗(yàn)證成功會(huì)返回結(jié)果和提示，結(jié)果為：200 ok,提示：Request successful即表示驗(yàn)證成功

我們這里驗(yàn)證比較多的是消息接口調(diào)試：文本消息、圖片消息、語音消息、視頻消息、etc

4、接口有不理解的地方，可進(jìn)入開發(fā)-->開發(fā)者工具-->開發(fā)者文檔進(jìn)行查詢

5、接口權(quán)限：訂閱號(hào)主要有基礎(chǔ)支持、接收消息及網(wǎng)頁服務(wù)里面的一些接口

下面我們主要講訂閱號(hào)怎么樣接收消息的案例：

1、需要申請(qǐng)一個(gè)個(gè)人微信訂閱號(hào)
2、url服務(wù)器和服務(wù)器端代碼部署（可以用騰訊云or阿里云服務(wù)器）

1）、AccountsServlet.java類，驗(yàn)證來自微信服務(wù)器和微信服務(wù)器的消息處理

package cn.jon.wechat.servlet; 
 
import java.io.IOException; 
import java.io.PrintWriter; 
 
import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
 
import cn.jon.wechat.service.AccountsService; 
import cn.jon.wechat.utils.SignUtil; 
 
public class AccountsServlet extends HttpServlet { 
 
 public AccountsServlet() { 
 super(); 
 } 
 
 
 public void destroy() { 
 super.destroy(); 
 // Put your code here 
 } 
 /** 
 * 確認(rèn)請(qǐng)求來自于微信服務(wù)器 
 */ 
 
 public void doGet(HttpServletRequest request, HttpServletResponse response) 
 throws ServletException, IOException { 
 System.out.println("接口測(cè)試開始?。?！"); 
 //微信加密簽名 
 String signature = request.getParameter("signature"); 
 //時(shí)間戳 
 String timestamp = request.getParameter("timestamp"); 
 //隨機(jī)數(shù) 
 String nonce = request.getParameter("nonce"); 
 //隨機(jī)字符串 
 String echostr = request.getParameter("echostr"); 
 
 PrintWriter out = response.getWriter(); 
 //通過校驗(yàn)signature對(duì)請(qǐng)求進(jìn)行校驗(yàn)，若校驗(yàn)成功則原樣返回echostr，表示接入成功，否則接入失敗 
 if(SignUtil.checkSignature(signature,timestamp,nonce)){ 
 out.print(echostr); 
 } 
 out.close(); 
 out = null; 
// response.encodeRedirectURL("success.jsp"); 
 
 
 } 
 /** 
 * 處理微信服務(wù)器發(fā)來的消息 
 */ 
 public void doPost(HttpServletRequest request, HttpServletResponse response) 
 throws ServletException, IOException { 
 //消息的接受、處理、響應(yīng) 
 request.setCharacterEncoding("utf-8"); 
 response.setCharacterEncoding("utf-8"); 
 //調(diào)用核心業(yè)務(wù)類型接受消息、處理消息 
 String respMessage = AccountsService.processRequest(request); 
 
 //響應(yīng)消息 
 PrintWriter out = response.getWriter(); 
 out.print(respMessage); 
 out.close(); 
 
 
 } 
 
 public void init() throws ServletException { 
 // Put your code here 
 } 
 
}

2）、SignUtil.java類，請(qǐng)求校驗(yàn)工具類，token需要和微信中填寫的token一致

package cn.jon.wechat.utils; 
 
import java.security.MessageDigest; 
import java.security.NoSuchAlgorithmException; 
import java.util.Arrays; 
import java.util.Iterator; 
import java.util.Map; 
import java.util.Set; 
import java.util.concurrent.ConcurrentHashMap; 
 
/** 
 * 請(qǐng)求校驗(yàn)工具類 
 * @author jon 
 */ 
public class SignUtil { 
 //與微信配置中的的Token一致 
 private static String token = ""; 
 
 public static boolean checkSignature(String signature, String timestamp, 
 String nonce) { 
 String[] arra = new String[]{token,timestamp,nonce}; 
 //將signature,timestamp,nonce組成數(shù)組進(jìn)行字典排序 
 Arrays.sort(arra); 
 StringBuilder sb = new StringBuilder(); 
 for(int i=0;i<arra.length;i++){ 
 sb.append(arra[i]); 
 } 
 MessageDigest md = null; 
 String stnStr = null; 
 try { 
 md = MessageDigest.getInstance("SHA-1"); 
 byte[] digest = md.digest(sb.toString().getBytes()); 
 stnStr = byteToStr(digest); 
 } catch (NoSuchAlgorithmException e) { 
 // TODO Auto-generated catch block 
 e.printStackTrace(); 
 } 
 //釋放內(nèi)存 
 sb = null; 
 //將sha1加密后的字符串與signature對(duì)比，標(biāo)識(shí)該請(qǐng)求來源于微信 
 return stnStr!=null?stnStr.equals(signature.toUpperCase()):false; 
 } 
 /** 
 * 將字節(jié)數(shù)組轉(zhuǎn)換成十六進(jìn)制字符串 
 * @param digestArra 
 * @return 
 */ 
 private static String byteToStr(byte[] digestArra) { 
 // TODO Auto-generated method stub 
 String digestStr = ""; 
 for(int i=0;i<digestArra.length;i++){ 
 digestStr += byteToHexStr(digestArra[i]); 
 } 
 return digestStr; 
 } 
 /** 
 * 將字節(jié)轉(zhuǎn)換成為十六進(jìn)制字符串 
 */ 
 private static String byteToHexStr(byte dByte) { 
 // TODO Auto-generated method stub 
 char[] Digit = {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'}; 
 char[] tmpArr = new char[2]; 
 tmpArr[0] = Digit[(dByte>>>4)&0X0F]; 
 tmpArr[1] = Digit[dByte&0X0F]; 
 String s = new String(tmpArr); 
 return s; 
 } 
 
 public static void main(String[] args) { 
 /*byte dByte = 'A'; 
 System.out.println(byteToHexStr(dByte));*/ 
 Map<String,String> map = new ConcurrentHashMap<String, String>(); 
 map.put("4", "zhangsan"); 
 map.put("100", "lisi"); 
 Set set = map.keySet(); 
 Iterator iter = set.iterator(); 
 while(iter.hasNext()){ 
// String keyV = (String) iter.next(); 
 String key =(String)iter.next(); 
 System.out.println(map.get(key)); 
// System.out.println(map.get(iter.next())); 
 } 
 /*for(int i=0;i<map.size();i++){ 
 
 }*/ 
 } 
}

3）、AccountsService.java服務(wù)類，主要是消息的請(qǐng)求和響應(yīng)處理，并且當(dāng)用戶關(guān)注你的公眾號(hào)的時(shí)候，可以設(shè)置默認(rèn)推送消息

package cn.jon.wechat.service;

import cn.jon.wechat.message.resp.TextMessage;

5）、BaseMessage.java消息基類(包括：開發(fā)者微信號(hào)、用戶賬戶、創(chuàng)建時(shí)間、消息類型、消息ID變量)，文本、視頻、圖片消息都會(huì)繼承此基類，在此基礎(chǔ)上擴(kuò)展自己的變量，可根據(jù)開發(fā)者文檔中的各種消息屬性進(jìn)行定義

package cn.jon.wechat.message.req;

6）、TextMessage.java文本消息，繼承自5中基類，擴(kuò)展內(nèi)容屬性

8）、VideoMessage.java視頻消息
