java微信公众号 java微信公众号开发案例

伟雪无痕 人气:0
想了解java微信公众号开发案例的相关内容吗,伟雪无痕在本文为您仔细讲解java微信公众号的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:java,微信公众号,下面大家一起来学习吧。

微信公众号开发一般是针对企业和组织的,个人一般只能申请订阅号,并且调用的接口有限,下面我们就来简单的描述下接入公众号的步骤

1、首先你需要一个邮箱在微信公众号平台进行注册;
     注册的方式有订阅号、公众号、小程序和企业号,个人我们这里只能选择订阅号

2、注册完后,我们登录到公众号平台--->开发--->基本配置,这里需要填写URL和token,URL就是我们使用服务器的接口;

3、Java Web服务器程序编译好且在服务器上部署可以运行的话,可在微信公众号进行在线接口调试:

    1)、选择合适的接口
    2)、系统会生成该接口的参数表,您可以直接在文本框内填入对应的参数值(红色星号表示该字段必填)
    3)、点击检查问题按钮,即可得到相应的调试信息

   eg:获取access_token的步骤:

   1)、接口类型:基础支持
   2)、接口列表:获取access_token接口/token
   3)、填写相应的参数:grant_type、appid、secret
   4)、点击检查问题
   5)、验证成功会返回结果和提示,结果为:200 ok,提示:Request successful即表示验证成功

   我们这里验证比较多的是消息接口调试:文本消息、图片消息、语音消息、视频消息、etc

4、接口有不理解的地方,可进入开发-->开发者工具-->开发者文档进行查询

5、接口权限:订阅号主要有基础支持、接收消息及网页服务里面的一些接口

下面我们主要讲订阅号怎么样接收消息的案例:

1、需要申请一个个人微信订阅号
2、url服务器和服务器端代码部署(可以用腾讯云or阿里云服务器)

1)、AccountsServlet.java类,验证来自微信服务器和微信服务器的消息处理

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 
 } 
 /** 
 * 确认请求来自于微信服务器 
 */ 
 
 public void doGet(HttpServletRequest request, HttpServletResponse response) 
 throws ServletException, IOException { 
 System.out.println("接口测试开始!!!"); 
 //微信加密签名 
 String signature = request.getParameter("signature"); 
 //时间戳 
 String timestamp = request.getParameter("timestamp"); 
 //随机数 
 String nonce = request.getParameter("nonce"); 
 //随机字符串 
 String echostr = request.getParameter("echostr"); 
 
 PrintWriter out = response.getWriter(); 
 //通过校验signature对请求进行校验,若校验成功则原样返回echostr,表示接入成功,否则接入失败 
 if(SignUtil.checkSignature(signature,timestamp,nonce)){ 
 out.print(echostr); 
 } 
 out.close(); 
 out = null; 
// response.encodeRedirectURL("success.jsp"); 
 
 
 } 
 /** 
 * 处理微信服务器发来的消息 
 */ 
 public void doPost(HttpServletRequest request, HttpServletResponse response) 
 throws ServletException, IOException { 
 //消息的接受、处理、响应 
 request.setCharacterEncoding("utf-8"); 
 response.setCharacterEncoding("utf-8"); 
 //调用核心业务类型接受消息、处理消息 
 String respMessage = AccountsService.processRequest(request); 
 
 //响应消息 
 PrintWriter out = response.getWriter(); 
 out.print(respMessage); 
 out.close(); 
 
 
 } 
 
 public void init() throws ServletException { 
 // Put your code here 
 } 
 
} 

2)、SignUtil.java类,请求校验工具类,token需要和微信中填写的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; 
 
/** 
 * 请求校验工具类 
 * @author jon 
 */ 
public class SignUtil { 
 //与微信配置中的的Token一致 
 private static String token = ""; 
 
 public static boolean checkSignature(String signature, String timestamp, 
 String nonce) { 
 String[] arra = new String[]{token,timestamp,nonce}; 
 //将signature,timestamp,nonce组成数组进行字典排序 
 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(); 
 } 
 //释放内存 
 sb = null; 
 //将sha1加密后的字符串与signature对比,标识该请求来源于微信 
 return stnStr!=null?stnStr.equals(signature.toUpperCase()):false; 
 } 
 /** 
 * 将字节数组转换成十六进制字符串 
 * @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; 
 } 
 /** 
 * 将字节转换成为十六进制字符串 
 */ 
 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服务类,主要是消息的请求和响应处理,并且当用户关注你的公众号的时候,可以设置默认推送消息

package cn.jon.wechat.service; 
 
import java.util.Date; 
import java.util.Map; 
 
import javax.servlet.http.HttpServletRequest; 
 
import cn.jon.wechat.message.req.ImageMessage; 
import cn.jon.wechat.message.req.LinkMessage; 
import cn.jon.wechat.message.req.LocationMessage; 
import cn.jon.wechat.message.req.VideoMessage; 
import cn.jon.wechat.message.req.VoiceMessage; 
import cn.jon.wechat.message.resp.TextMessage; 
import cn.jon.wechat.utils.MessageUtil; 
 
/** 
 * 解耦,使控制层与业务逻辑层分离开来,主要处理请求,响应 
 * @author jon 
 */ 
public class AccountsService { 
 
 public static String processRequest(HttpServletRequest request) { 
 String respMessage = null; 
 //默认返回的文本消息内容 
 String respContent = "请求处理异常,请稍后尝试!"; 
 try { 
 //xml请求解析 
 Map<String,String> requestMap = MessageUtil.pareXml(request); 
 
 //发送方账号(open_id) 
 String fromUserName = requestMap.get("FromUserName"); 
 //公众账号 
 String toUserName = requestMap.get("ToUserName"); 
 //消息类型 
 String msgType = requestMap.get("MsgType"); 
 
 //默认回复此文本消息 
 TextMessage defaultTextMessage = new TextMessage(); 
 defaultTextMessage.setToUserName(fromUserName); 
 defaultTextMessage.setFromUserName(toUserName); 
 defaultTextMessage.setCreateTime(new Date().getTime()); 
 defaultTextMessage.setMsgType(MessageUtil.MESSSAGE_TYPE_TEXT); 
 defaultTextMessage.setFuncFlag(0); 
 // 由于href属性值必须用双引号引起,这与字符串本身的双引号冲突,所以要转义 
 defaultTextMessage.setContent("欢迎访问<a href=\"http://blog.csdn.net/j086924\">jon的博客</a>!"); 
// defaultTextMessage.setContent(getMainMenu()); 
 // 将文本消息对象转换成xml字符串 
 respMessage = MessageUtil.textMessageToXml(defaultTextMessage); 
 
 
 //文本消息 
 if(msgType.equals(MessageUtil.MESSSAGE_TYPE_TEXT)){ 
 //respContent = "Hi,您发送的是文本消息!"; 
 //回复文本消息

 imageMessage.setMsgType(MessageUtil.MESSSAGE_TYPE_IMAGE); 
 //respContent=requestMap.get("PicUrl"); 
 imageMessage.setPicUrl("http://img24.pplive.cn//2013//07//24//12103112092_230X306.jpg"); 
 respMessage = MessageUtil.imageMessageToXml(imageMessage); 
 } 
 //地理位置

 locationMessage.setMsgType(MessageUtil.MESSSAGE_TYPE_LOCATION); 
 locationMessage.setLocation_X(requestMap.get("Location_X")); 
 locationMessage.setLocation_Y(requestMap.get("Location_Y")); 
 locationMessage.setScale(requestMap.get("Scale")); 
 locationMessage.setLabel(requestMap.get("Label")); 
 respMessage = MessageUtil.locationMessageToXml(locationMessage); 
  
 } 
 
 //视频消息 
 else if(msgType.equals(MessageUtil.MESSSAGE_TYPE_VIDEO)){ 
 VideoMessage videoMessage=new VideoMessage(); 
 videoMessage.setToUserName(fromUserName); 
 videoMessage.setFromUserName(toUserName); 
 videoMessage.setCreateTime(new Date().getTime()); 
 videoMessage.setMsgType(MessageUtil.MESSSAGE_TYPE_VIDEO); 
 videoMessage.setMediaId(requestMap.get("MediaId")); 
 videoMessage.setThumbMediaId(requestMap.get("ThumbMediaId")); 
 respMessage = MessageUtil.videoMessageToXml(videoMessage); 
  
 } 
 //链接消息 
 else if(msgType.equals(MessageUtil.MESSSAGE_TYPE_LINK)){ 
 LinkMessage linkMessage=new LinkMessage(); 
 linkMessage.setToUserName(fromUserName);

 linkMessage.setTitle(requestMap.get("Title")); 
 linkMessage.setDescription(requestMap.get("Description")); 
 linkMessage.setUrl(requestMap.get("Url")); 
 respMessage = MessageUtil.linkMessageToXml(linkMessage); 
 } 
 //语音消息 
 else if(msgType.equals(MessageUtil.MESSSAGE_TYPE_VOICE)){ 
 VoiceMessage voiceMessage=new VoiceMessage();

 voiceMessage.setFormat(requestMap.get("Format")); 
 respMessage = MessageUtil.voiceMessageToXml(voiceMessage); 
 } 
 //事件推送 
 else if(msgType.equals(MessageUtil.MESSSAGE_TYPE_EVENT)){ 
 //事件类型 
 String eventType = requestMap.get("Event"); 
 //订阅

  //自定义菜单消息处理 
  System.out.println("自定义菜单消息处理"); 
 } 
 } 
 
 } catch (Exception e) { 
 // TODO Auto-generated catch block 
 e.printStackTrace(); 
 } 
 return respMessage; 
 } 
 
 public static String getMainMenu() 
 { 
 StringBuffer buffer =new StringBuffer(); 
 buffer.append("您好,我是jon,请回复数字选择服务:").append("\n"); 
 buffer.append("1、我的博客").append("\n"); 
 buffer.append("2、 歌曲点播").append("\n"); 
 buffer.append("3、 经典游戏").append("\n"); 
 buffer.append("4 、聊天打牌").append("\n\n"); 
 buffer.append("回复"+"0"+"显示帮助菜单"); 
 return buffer.toString(); 
 
 } 
} 

4)、MessageUtil.java帮助类,包括常量的定义和xml消息转换和处理

package cn.jon.wechat.utils; 
 
import java.io.InputStream;

 } 
 /**

  writer.write("]]>"); 
  }else{ 
  writer.write(text); 
  } 
 } 
 }; 
 } 
 }); 
 
} 

5)、BaseMessage.java消息基类(包括:开发者微信号、用户账户、创建时间、消息类型、消息ID变量),文本、视频、图片消息都会继承此基类,在此基础上扩展自己的变量,可根据开发者文档中的各种消息属性进行定义

package cn.jon.wechat.message.req; 
/** 
 * 消息基类 (普通用户-公众号) 
 * @author jon 
 */ 
public class BaseMessage { 
 
 //开发者微信号 
 private String ToUserName; 
 //发送方账号(一个openId) 
 private String FromUserName; 
 //消息创建时间(整型) 
 private long CreateTime; 
 //消息类型(text/image/location/link...) 
 private String MsgType; 
 //消息id 64位整型 
 private String MsgId; 
 
 public BaseMessage() { 
 super(); 
 // TODO Auto-generated constructor stub 
 } 
 
 public BaseMessage(String toUserName, String fromUserName, long createTime, 
 String msgType, String msgId) { 
 super(); 
 ToUserName = toUserName; 
 FromUserName = fromUserName; 
 CreateTime = createTime; 
 MsgType = msgType; 
 MsgId = msgId; 
 } 
 
 public String getToUserName() { 
 return ToUserName; 
 } 
 
 public void setToUserName(String toUserName) { 
 ToUserName = toUserName; 
 } 
 
 public String getFromUserName() { 
 return FromUserName; 
 } 
 
 public void setFromUserName(String fromUserName) { 
 FromUserName = fromUserName; 
 } 
 public long getCreateTime() { 
 return CreateTime; 
 } 
 
 public void setCreateTime(long createTime) { 
 CreateTime = createTime; 
 } 
 public String getMsgType() { 
 return MsgType; 
 } 
 
 public void setMsgType(String msgType) { 
 MsgType = msgType; 
 } 
 public String getMsgId() { 
 return MsgId; 
 } 
 
 public void setMsgId(String msgId) { 
 MsgId = msgId; 
 } 
} 

6)、TextMessage.java文本消息,继承自5中基类,扩展内容属性

package cn.jon.wechat.message.req; 
/** 
 * 文本消息 
 * @author jon 
 */ 
public class TextMessage extends BaseMessage{ 
 //消息内容 
 private String content; 
 
 public String getContent() { 
 return content; 
 } 
 
 public void setContent(String content) { 
 this.content = content; 
 } 
 
} 

7)、ImageMessage.java图片消息 

package cn.jon.wechat.message.req; 
/** 
 * 图片消息 
 * @author jon 
 */ 
public class ImageMessage extends BaseMessage{ 
 //图片链接 
 private String PicUrl; 
 
 public String getPicUrl() { 
 return PicUrl; 
 } 
 
 public void setPicUrl(String picUrl) { 
 PicUrl = picUrl; 
 } 
} 

8)、VideoMessage.java视频消息

package cn.jon.wechat.message.req; 
 
public class VideoMessage extends BaseMessage { 
 
 private String mediaId; 
 private String thumbMediaId; 
 public String getMediaId() { 
 return mediaId; 
 } 
 public void setMediaId(String mediaId) { 
 this.mediaId = mediaId; 
 } 
 public String getThumbMediaId() { 
 return thumbMediaId; 
 } 
 public void setThumbMediaId(String thumbMediaId) { 
 this.thumbMediaId = thumbMediaId; 
 } 
 
} 

其他消息类可根据开发者文档自行进行完成,另外,开发者也可以申请公众平台测试账号,对开发的相关内容进行测试。
