最近一直在看计算机视觉方面的论文,尽量抽时间复习下微服务吧。
微信自定义菜单文档地址:https://developers.weixin.qq.com/doc/offiaccount/Custom_Menus/Creating_Custom-Defined_Menu.html
微信自定义菜单注意事项:
1. 自定义菜单最多包括3个一级菜单,每个一级菜单最多包含5个二级菜单。
2. 一级菜单最多4个汉字,二级菜单最多8个汉字,多出来的部分将会以“…”代替。
3. 创建自定义菜单后,菜单的刷新策略是,在用户进入公众号会话页或公众号profile页时,如果发现上一次拉取菜单的请求在5分钟以前,就会拉取一下菜单,如果菜单有更新,就会刷新客户端的菜单。测试时可以尝试取消关注公众账号后再次关注,则可以看到创建后的效果。
一级菜单:直播、课程、我的
二级菜单:根据一级菜单动态设置二级菜单,直播(近期直播课程),课程(课程分类),我的(我的订单、我的课程、我的优惠券及关于我们)
说明:
1、二级菜单可以是网页类型,点击跳转H5页面
2、二级菜单可以是消息类型,点击返回消息
自定义菜单通过后台管理设置到数据库表,数据配置好后,通过微信接口推送菜单数据到微信平台。
表结构如下:
(1)页面功能“列表、添加、修改与删除”是对menu表的操作
(2)页面功能“同步菜单与删除菜单”是对微信平台接口操作
(1)在service下创建子模块service_wechat
(2)引入依赖
<dependencies>
<dependency>
<groupId>com.github.binarywang</groupId>
<artifactId>weixin-java-mp</artifactId>
<version>4.1.0</version>
</dependency>
</dependencies>
(1)启动类
@SpringBootApplication

@MapperScan("com.atguigu.ggkt.wechat.mapper")
@ComponentScan(basePackages = "com.atguigu")
public class ServiceWechatApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceWechatApplication.class, args);
}
}
(2)配置文件

(1)MenuService定义方法
public interface MenuService extends IService<Menu> {
//获取全部菜单
List<MenuVo> findMenuInfo();
//获取一级菜单
List<Menu> findOneMenuInfo();
}
(2)MenuServiceImpl实现方法
@Slf4j
@Service
public class MenuServiceImpl extends ServiceImpl<MenuMapper, Menu> implements MenuService {
@Autowired
private WxMpService wxMpService;
//获取所有菜单,按照一级和二级菜单封装
@Override
public List<MenuVo> findMenuInfo() {
//1、创建List集合,用于最终数据封装
List<MenuVo> finalMenuList=new ArrayList<>();
//2、查询出所有菜单数据(包含一级和二级)
List<Menu> menuList = baseMapper.selectList(null);
//3、从所有菜单数据中获取所有一级菜单数据(parent_id=0)
List<Menu> oneMenuList = menuList.stream()
.filter(menu -> menu.getParentId() == 0)
.collect(Collectors.toList());
//4、封装一级菜单数据,封装到最终数据list集合
//遍历一级菜单list集合
oneMenuList.forEach(oneMenu->{
//Menu -->MenuVo
MenuVo oneMenuVo = new MenuVo();
BeanUtils.copyProperties(oneMenu,oneMenuVo);
//5、封装二级菜单数据(判断一级菜单id和二级菜单的parent_id是否相同)
//如果相同,把二级菜单数据放到一级菜单里面
List<Menu> twoMenuList = menuList.stream()
.filter(menu -> menu.getParentId().equals(oneMenu.getId()))
.collect(Collectors.toList());
//List<Menu>->List<MenuVo>
List<MenuVo> children=new ArrayList<>();
twoMenuList.forEach(twoMenu -> {
MenuVo twoMenuVo = new MenuVo();
BeanUtils.copyProperties(twoMenu,twoMenuVo);
children.add(twoMenuVo);
});
//把二级菜单数据放到一级菜单里面
oneMenuVo.setChildren(children);
//把oneMenuVo放到最终list集合
finalMenuList.add(oneMenuVo);
});
//返回最终数据
return finalMenuList;
}
//获取所有一级菜单
@Override
public List<Menu> findMenuOneInfo() {
QueryWrapper<Menu> wrapper=new QueryWrapper<>();
wrapper.eq("parent_id",0);
List<Menu> list = baseMapper.selectList(wrapper);
return list;
}
//同步公众号菜单方法
//https://developers.weixin.qq.com/doc/offiaccount/Custom_Menus/Creating_Custom-Defined_Menu.html
//https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Get_access_token.html
@Override
public void syncMenu() {
//获取所有菜单数据
List<MenuVo> menuVoList = this.findMenuInfo();
//封装button里面的结构,数组格式
JSONArray buttonList=new JSONArray();
menuVoList.forEach(oneMenuVo -> {
//json对象 一级菜单
JSONObject one=new JSONObject();
one.put("name",oneMenuVo.getName());
//json数组 二级菜单
JSONArray subButton=new JSONArray();
oneMenuVo.getChildren().forEach(twoMenuVo->{
JSONObject view = new JSONObject();
view.put("type", twoMenuVo.getType());
if(twoMenuVo.getType().equals("view")) {
view.put("name", twoMenuVo.getName());
view.put("url", "http://ggkt2.vipgz1.91tunnel.com/#"
+twoMenuVo.getUrl());
} else {
view.put("name", twoMenuVo.getName());
view.put("key", twoMenuVo.getMeunKey());
}
subButton.add(view);
});
one.put("sub_button",subButton);
buttonList.add(one);
});
//封装最外层的button部分
JSONObject button=new JSONObject();
button.put("button",buttonList);
try {
String menuId =
this.wxMpService.getMenuService().menuCreate(button.toJSONString());
log.info("menuId:{}",menuId);
} catch (WxErrorException e) {
e.printStackTrace();
throw new GgktException(20001,"公众号菜单同步失败");
}
}
//公众号菜单删除
@Override
public void removeMenu() {
try {
wxMpService.getMenuService().menuDelete();
} catch (WxErrorException e) {
e.printStackTrace();
throw new GgktException(20001,"公众号菜单删除失败");
}
}
}
(1)进行菜单同步时候,需要获取到公众号的access_token,通过access_token进行菜单同步

接口调用请求说明
http请求方式:POST(请使用https协议) https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN
weixin-java-mp是封装好了的微信接口客户端,使用起来很方便,后续我们就使用weixin-java-mp处理微信平台接口。

(1)src -> router -> index.js添加路由

name: 'Menu',
component: () => import('@/views/wechat/menu/list'),
meta: { title: '菜单列表' }
}
]
},
(1)src -> api -> wechat -> menu.js定义接口
import request from '@/utils/request'
const api_name = '/admin/wechat/menu'
export default {
findMenuInfo() {
return request({
url: `${api_name}/findMenuInfo`,
method: `get`
})

后端微服务启动
nacos查看服务是否注册成功。
前端项目启动
登录之后,点击公众号菜单管理->菜单列表
点击同步菜单
然后进入测试号中看是否同步成功。
菜单同步到这里就基本做完了。
