菜单相关的介绍都在 [https://mp.weixin.qq.com/wiki?t=resource/res\_main&id=mp1421141013][https_mp.weixin.qq.com_wiki_t_resource_res_main_id_mp1421141013]

package com.tsing.wechat.service;
    
    import com.tsing.wechat.utils.HttpUtils;

    import lombok.extern.slf4j.Slf4j;

    import java.io.IOException;
    
    @Slf4j
    @Service
    public class MenuService { 
    
        private static final String MENU_CREATE_URL = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=%s";
        private static final String MENU_GET_URL = "https://api.weixin.qq.com/cgi-bin/menu/get?access_token=%s";
        private static final String MENU_DELETE_URL = "https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=%s";
    
        @Resource
        private WxUserInfoService wxUserInfoService;
    
        public void getMenu() { 
            String access_token = wxUserInfoService.getToken();
            String url = String.format(MENU_GET_URL, access_token);
            String res = HttpUtils.doGet(url);
            log.info("获取菜单返回：{}", res);
        }
    
        public void createMenu() throws IOException { 
            String access_token = wxUserInfoService.getToken();
            String url = String.format(MENU_CREATE_URL, access_token);
            String json = ResourceUtils.getResourceString("/menu.txt");
            log.info("创建菜单的参数：{}", json);
            String res = HttpUtils.doPost(url, json);
            log.info("创建菜单返回：{}", res);
        }
    
        public void delMenu() { 
            String access_token = wxUserInfoService.getToken();
            String url = String.format(MENU_DELETE_URL, access_token);
            String res = HttpUtils.doGet(url);
            log.info("删除菜单返回：{}", res);
        }
    
    }

wxUserInfoService 是为了获取到access\_token，这里我就不赘述了。 菜单创建删除获取的三个url列在了上面。

这次我创建菜单的样式menu.txt是：

{
         "button":[
         {
              "type":"click",
              "name":"用户信息",
              "key":"USER_INFO_CLICK"
          },
          {
               "name":"菜单",
               "sub_button":[
               {
                   "type":"view",
                   "name":"搜索",
                   "url":"http://www.baidu.com"
                },
                {
                   "type":"click",
                   "name":"赞一下我们",
                   "key":"V1001_GOOD"
                }]
           },
           {
               "name": "扫码",
               "sub_button": [
                   {
                       "type": "scancode_waitmsg",
                       "name": "扫码带提示",
                       "key": "rselfmenu_0_0",
                       "sub_button": [ ]
                   },
                   {
                       "type": "scancode_push",
                       "name": "扫码推事件",
                       "key": "rselfmenu_0_1",
                       "sub_button": [ ]
                   }
               ]
           }]
     }

创建出来以后的样子是

![在这里插入图片描述][70]

点用户信息，发送一个 click 事件消息到我们配置的接口。时间的event\_key 是 USER\_INFO\_CLICK。 可以自行更具需要返回消息。 第二个菜单的\*\*“搜索”\*\*， 我们设置的是view , 点击不会向服务器发消息，直接打开配置的url, 这里点了以后是通过微信自带的浏览器打开了百度。
