微信公众号自定义菜单
微信公众平台自定义菜单接口文档：https://mp.weixin.qq.com/wiki/10/0234e39a2025342c17a7d23595c6b40a.html
最近做了下公众号的自定义菜单，下面贴上每一步的操作步骤，一共三步：
1.调用公众号创建自定义菜单接口创建自己想要的菜单（创建自定义菜单表，存储自定义菜单内容，方便后续更新）：
举例如下：
levelNum列:菜单级别(1：父菜单，2子菜单)
father列：父级菜单是谁
type列: main：一级菜单，click:点击事件，view：跳转路径，
name：展示的名称
contentText:如果是一级菜单，配置main或者不配(null)都行，配置view也可以，但是切记一级菜单不能直接配click这类的点击事件,否则创建菜单时会失败
contentText与contentType配置对应关系：
main ------>main
cilck ------>key
view ------>url
sequence:展示的顺序
siteId:刷新哪个站点的菜单
后台添加菜单功能如图：
然后做一个刷新自定义菜单的按钮，后期如果菜单有更新，点击按钮判断刷新的是哪个站点的菜单就行了
刷新自定义菜单就是调用微信的创建自定义菜单接口：
package com.odao.weixin.site.web.controller.createMenu;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Writer;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;

import java.util.Map;

@Controller
@RequestMapping("/")
public class CreateMenuController {
final static Logger logger = LoggerFactory.getLogger(CreateMenuController.class);
@Autowired
private CustomButtonSys customButtonSys;
@RequestMapping("creatMenu.do")
protected void handleRequestInternal(HttpServletRequest request,
HttpServletResponse response,Writer writer) throws Exception {
boolean b=false;
String accesstoken=null;
String text=null;
logger.debug("创建自定义菜单请求");
//获取基础token
try {
String token = AccessTokenKit.getTokenNew(微信公众号appid, 微信公众号Secret);
accesstoken = (String) JSON.parseObject(token, Map.class).get("access_token");//通过AppId 和 AppSecret 获取access_token
} catch (Exception e1) {
e1.printStackTrace();
}
//创建菜单语句
text = customButtonSys.getCreatText();
logger.debug("创建自定义菜单请求的text["+text+"]");
if(accesstoken!=null&&accesstoken.length()>0&&text!=null&&text.length()>0){
try {
b=MenuManager.createMenu(accesstoken, text);//通过access_token和页面提交的按钮创建字符串创建自定义菜单，成功返回true，失败返回false
} catch (KeyManagementException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (NoSuchProviderException e) {
e.printStackTrace();
}
}
int result = 0;
if(b){
result = 1;
} else {
result = 0;
}
logger.debug("创建自定义菜单结果："+result);
response.setContentType("text/plain");
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
PrintWriter out;
try {
out = response.getWriter();
JSONObject resultJSON = new JSONObject();
String jsonpCallback = request.getParameter("jsonpCallback");// 客户端请求参数
resultJSON.put("retCode", result);
out.println(jsonpCallback + "(" + resultJSON.toString(1, 1)+")");// 返回jsonp格式数据
out.flush();
out.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return;
}
}
写得比较简陋，你可以自己优化下，功能反正没问题。
2.配置微信公众号事件转发地址：
进入微信公众号，左侧菜单找到基本配置，配置如下：
3.编写菜单点击触发事件:
配置好后，你的自定义菜单点击事件都会转发到你的后台Java方法中：
package com.odao.weixin.site.web.controller.weixinListener;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.Writer;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.odao.weixin.api.msg.*;
import com.odao.weixin.site.subsys.listener.ListenerEventService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.odao.common.util.HttpUtil;
import com.odao.weixin.api.DefaultSession;
import com.odao.weixin.api.HandleMessageAdapter;
import com.odao.weixin.api.support.MySecurity;
import com.odao.weixin.site.util.QpMobileGameWebUtil;
@Controller
@RequestMapping("/")
public class WeiXinListenerController {
final static Logger logger = LoggerFactory.getLogger(WeiXinListenerController.class);
// TOKEN 是你在微信平台开发模式中设置的哦
public static final String TOKEN = "上图中的Token(令牌)";
@Autowired
private ListenerEventService listenerEventService;
@RequestMapping("weiXinListener.do")
protected void handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
String method = request.getMethod();
logger.debug("请求类型：" + method);
if ("GET".equals(method)) {
doGet(request, response);
}
if ("POST".equals(method)) {
doPost(request, response);
}
}
/**
* 微信验证
*
* @param request
* @param response
* @throws Exception
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws Exception {
logger.debug("==================================================");
logger.debug("微信验证交互请求！！");
Writer writer = response.getWriter();
String signature = request.getParameter("signature");// 微信加密签名
String timestamp = request.getParameter("timestamp");// 时间戳
String nonce = request.getParameter("nonce");// 随机数
String echostr = request.getParameter("echostr");// 随机字符串
// 重写totring方法，得到三个参数的拼接字符串
List<String> list = new ArrayList<String>(3) {
private static final long serialVersionUID = 2621444383666420433L;
public String toString() {
return this.get(0) + this.get(1) + this.get(2);
}
};
list.add(TOKEN);
list.add(timestamp);
list.add(nonce);
try {
Collections.sort(list);// 排序
String tmpStr = new MySecurity().encode(list.toString(),
MySecurity.SHA_1);// SHA-1加密
if (signature.equals(tmpStr)) {
QpMobileGameWebUtil.writeString(writer, echostr);
} else {
QpMobileGameWebUtil.writeString(writer, "");
}
} catch (Exception e) {
QpMobileGameWebUtil.writeString(writer, "");
}
}
/**
* 微信监听
*
* @param request
* @param response
* @throws Exception
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws Exception {
logger.debug("==================================================");
logger.debug("微信监听请求！");
request.setCharacterEncoding("utf-8");
response.setContentType("text/html; charset=utf-8");
InputStream is = request.getInputStream();
OutputStream os = response.getOutputStream();
final DefaultSession session = DefaultSession.newInstance();
final String uploadPath = request.getSession().getServletContext()
.getRealPath("/");// 获取项目路径
// 请求IP
final String requestIP = HttpUtil.getIpAddr(request);
// 处理事件(事件都会到此处)
session.addOnHandleMessageListener(new HandleMessageAdapter() {
// 获取基础token
public void onEventMsg(Msg4Event msg) {
listenerEventService.onEventMsg(session, msg, requestIP,uploadPath);
}
}
);
session.process(is, os);// 处理微信消息
session.close();// 关闭Session
}
}
我们来看看listenerEventService.onEventMsg(session, msg, requestIP,uploadPath)方法：
package com.odao.weixin.site.subsys.listener;
import java.util.Map;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.alibaba.fastjson.JSON;
import com.odao.weixin.api.DefaultSession;
import com.odao.weixin.api.msg.Msg4Event;
import com.odao.weixin.api.msg.Msg4Text;
import com.odao.weixin.api.msg.UserInfo;
import com.odao.weixin.api.support.AccessTokenKit;
import com.odao.weixin.site.cases2017.wxpay.service.SyncXMLUtils;
import com.odao.weixin.site.core.GlobalThreadLocal;
import com.odao.weixin.site.subsys.MenuEvent.MenuEventSys;
import com.odao.weixin.site.subsys.config.WeiXinProcessConfigSys;
import com.odao.weixin.site.subsys.publicsys.UserManager;
import com.odao.weixin.site.subsys.user.GameUserSys;
/**
* 微信监听处理事件
*
* @author Administrator
*
*/
@Service
public class ListenerEventService {
final static Logger logger = LoggerFactory.getLogger(ListenerEventService.class);
private String respContent;
/**
* 处理事件
*
* @param session
* @param msg
*/
public void onEventMsg(DefaultSession session, Msg4Event msg,String requestIP, String uploadPath) {
String eventType = msg.getEvent();
// ============================订阅关注=============================================
if (Msg4Event.SUBSCRIBE.equals(eventType)) {
Msg4Text reMsg = new Msg4Text();
reMsg.setFromUserName(msg.getToUserName());
reMsg.setToUserName(msg.getFromUserName());
reMsg.setCreateTime(msg.getCreateTime());
reMsg.setContent(respContext);
session.callback(reMsg);// 回传消息
}
// ============================已经关注了的==========================================
else if (Msg4Event.SCAN.equals(eventType)) {}
// ============================取消订阅=============================================
else if (Msg4Event.UNSUBSCRIBE.equals(eventType)) {}
// ============================点击事件=============================================
else if (Msg4Event.CLICK.equals(eventType)) {
//kfrx就是你之前配置菜单时定义的contentText列内容
if("kfrx".equals(msg.getEventKey())){
//do something you want....
}
}
}
}
上述列举了菜单中点击触发的4中类型，订阅关注、已经关注了的、取消关注、点击事件(你之前配置的click)
按照上述操作一步步来，你的自定义菜单就完成啦
不过你开了自己的自定义菜单，公众号中的自定义菜单就被禁用啦，看你自己的需求，到底是自己去公众号配置自定义菜单，还是自己开发自定义回复的才惨吧。
