如何在项目中整合微信公众号开发（上）

050

最近在写web项目的过程中接触到公众号开发，在这码一码整个开发的流程

一、配置微信公众号测试号

微信测试号平台链接 mp.weixin.qq.com
扫描登录进入，获取测试号信息：appID与appsecret，这两个很重要！！页面下方的二维码就是我们本次项目中使用到的测试号，可以自己扫码关注一下

如下是官方的开发文档，感兴趣的可以看看 微信公众平台开发概述 | 微信开放文档 (qq.com)

在本项目中采用的是weixin-java-mp工具进行开发，下面对其进行配置。

二、配置weixin-java-mp

2.1 在application-dev.yml中添加配置

# 注意不是在spring下！！！
wechat:
  mpAppId: # 上面提到的两个属性复制粘贴进去
  mpAppSecret: 
# 注意不是在spring下！！！
wechat:
  mpAppId: # 上面提到的两个属性复制粘贴进去
  mpAppSecret: 
# 注意不是在spring下！！！
wechat:
  mpAppId: # 上面提到的两个属性复制粘贴进去
  mpAppSecret:

2.2 引入依赖

在项目pom文件中引入依赖，记得更新重启一下项目?

<dependency>
    <groupId>com.github.binarywang</groupId>
    <artifactId>weixin-java-mp</artifactId>
    <version>4.1.0</version>
</dependency>
<dependency>
    <groupId>com.github.binarywang</groupId>
    <artifactId>weixin-java-mp</artifactId>
    <version>4.1.0</version>
</dependency>
<dependency>
    <groupId>com.github.binarywang</groupId>
    <artifactId>weixin-java-mp</artifactId>
    <version>4.1.0</version>
</dependency>

2.3 添加工具类和配置类

    @Autowired

    @Bean
    public WxMpService wxMpService(){
        WxMpService wxMpService = new WxMpServiceImpl();
        wxMpService.setWxMpConfigStorage(wxMpConfigStorage());
        return wxMpService;
    }
    @Bean
    public WxMpConfigStorage wxMpConfigStorage(){

        wxMpConfigStorage.setSecret(wechatAccountConfig.getMpAppSecret());
        return wxMpConfigStorage;
    }
}

后续通过这里配置的WxMpService来操作微信公众号

三、添加自定义菜单

一个公众号肯定少不了相关的菜单栏，这里步里会讲述如何添加自定义菜单
下图是微信官方指定的菜单格式，由于官方只认这一个格式，所以我们需要将从数据库获取到的数据转换成该格式

image-20230622171602354.png

3.1 menuController中定义方法

@PreAuthorize("hasAuthority('bnt.menu.syncMenu')") //权限控制
@ApiOperation(value = "同步菜单")
@GetMapping("syncMenu")
public Result syncMenu() {
    menuService.syncMenu();
    return Result.success();
}
@PreAuthorize("hasAuthority('bnt.menu.syncMenu')") //权限控制
@ApiOperation(value = "同步菜单")
@GetMapping("syncMenu")
public Result syncMenu() {
    menuService.syncMenu();
    return Result.success();
}
@PreAuthorize("hasAuthority('bnt.menu.syncMenu')") //权限控制
@ApiOperation(value = "同步菜单")
@GetMapping("syncMenu")
public Result syncMenu() {
    menuService.syncMenu();
    return Result.success();
}

3.2 menuService中重写该方法

@Service
public void menuServiceImpl(){
    @Autowired
    private WxMpService wxMpService;
    //获取菜单树形结构
    @Override
    public List<MenuVo> findMenuInfo() {
        List<Menu> menus = weChatMenuMapper.selectList(null);
        //获取到所有的父级菜单
        List<Menu> menusParent = menus.stream().filter(menu -> menu.getParentId().longValue() == 0)
                .collect(Collectors.toList());
        List<MenuVo> menuVoList = new ArrayList<>();
        for(Menu menu : menusParent){
            MenuVo menuVo = new MenuVo();
            BeanUtils.copyProperties(menu,menuVo);
            //获取到所有的二级目录
            List<Menu> subMenuList = menus.stream().filter(myMenu -> myMenu.getParentId().longValue() == menu.getId())
                    .sorted(Comparator.comparing(Menu::getSort))
                    .collect(Collectors.toList());
            //遍历转换
            List<MenuVo> children = new ArrayList<>();
            for(Menu menu1 : subMenuList){
                MenuVo myMenuVo  = new MenuVo();
                BeanUtils.copyProperties(menu1,myMenuVo);
                children.add(myMenuVo);
            }
            menuVo.setChildren(children);
            menuVoList.add(menuVo);
        }
        return menuVoList;
    }
    
    @Override
    public void syncMenu() {
        //将数据库中存储的数据封装为层级关系
        List<MenuVo> menuVoList = this.findMenuInfo();
        //菜单
        JSONArray buttonList = new JSONArray();
        for(MenuVo oneMenuVo : menuVoList) {
            JSONObject one = new JSONObject();
            one.put("name", oneMenuVo.getName());
            if(CollectionUtils.isEmpty(oneMenuVo.getChildren())) {
                one.put("type", oneMenuVo.getType());
                one.put("url", "http://oa.charles.vip.tunnel/#"+oneMenuVo.getUrl());
            } else {
                JSONArray subButton = new JSONArray();
                for(MenuVo twoMenuVo : oneMenuVo.getChildren()) {
                    JSONObject view = new JSONObject();
                    view.put("type", twoMenuVo.getType());
                    if(twoMenuVo.getType().equals("view")) {
                        view.put("name", twoMenuVo.getName());
                        //H5页面地址 这里队应的是内网穿透的地址 后面会讲
                        view.put("url", "http://oa.charles.vip.tunnel/#"+twoMenuVo.getUrl())
                    } else {
                        view.put("name", twoMenuVo.getName());
                        view.put("key", twoMenuVo.getMeunKey());
                    }
                    subButton.add(view);
                }
                one.put("sub_button", subButton);
            }
            buttonList.add(one);
        }
        //菜单
        JSONObject button = new JSONObject();
        button.put("button", buttonList);
        try {
            //固定格式 调用方法来生成菜单
            wxMpService.getMenuService().menuCreate(button.toJSONString());
        } catch (WxErrorException e) {

        } catch (WxErrorException e) {
            throw new RuntimeException(e);
        }
    }
}

最终效果如下图所示

四、 配置内网穿透

前面我们完成配置公众号的菜单，当点击菜单的时候会跳转到我们本地的页面中，但是由于是内网，外网无法直接访问。这时候可以采用内网穿透技术或者ip来实现功能，当然注册域名更好? 这里以ngrok为例子进行内网穿透 ngrok.cc

4.1 开通隧道（需实名认证）

配置好本地端口，由于我们有两个端口所以需要两条隧道（前端页面，后端接口）

Snipaste_2023-06-22_17-45-04.png
开通成功后会看到隧道id，通过下载客户端然后启动当前隧道就ok了

4.2 配置“授权回调页面域名”

在网页服务-网页账号-修改 处修改，配置的地址为后端接口的地址，比如我后端接口8080对应地址oa.charles.vip.tunnel.com （即复制该地址上去 注意无需前缀http://）

Snipaste_2023-06-22_17-53-27.png

4.3 配置授权回调获取用户信息接口地址

wechat:
      # 跟着前面配置过的myAppId等
  # 授权回调获取用户信息接口地址
  userInfoUrl: http://oa.charles.vip.tunnel.com/admin/wechat/userInfo
wechat:
      # 跟着前面配置过的myAppId等
  # 授权回调获取用户信息接口地址
  userInfoUrl: http://oa.charles.vip.tunnel.com/admin/wechat/userInfo
wechat:
      # 跟着前面配置过的myAppId等
  # 授权回调获取用户信息接口地址
  userInfoUrl: http://oa.charles.vip.tunnel.com/admin/wechat/userInfo

五、编写后端接口

在controller中我们需要定义三个方法，分别是
userInfo — 获取用户信息 OpenId为微信的唯一标识

@GetMapping("/userInfo")
public String userInfo(@RequestParam("code") String code,
                       @RequestParam("state") String returnUrl) throws Exception {
    
    System.out.println("code " + code);
    System.out.println("returnUrl " + returnUrl);
    //获取认证token
    WxOAuth2AccessToken accessToken = wxMpService.getOAuth2Service().getAccessToken(code);
    //从token中获取openId
    String openId = accessToken.getOpenId();
    //查找user表中是否存在该openId
    LambdaQueryWrapper<SysUser> lambdaQueryWrapper = new LambdaQueryWrapper<SysUser>();
    lambdaQueryWrapper.eq(SysUser::getOpenId,openId);
    SysUser sysUser = sysUserService.getOne(lambdaQueryWrapper);
    //最终前端都是通过token来判断
    String token = "";
    //null != sysUser 说明已经绑定，反之为建立账号绑定，去页面建立账号绑定
    if(null != sysUser) {
        token = JWTHelper.createToken(sysUser.getId(), sysUser.getUsername());
        System.out.println("token " + token);
    }
    if(returnUrl.indexOf("?") == -1) {
        return "redirect:" + returnUrl + "?token=" + token + "&openId=" + openId;
    } else {
        return "redirect:" + returnUrl + "&token=" + token + "&openId=" + openId;
    }
}
@GetMapping("/userInfo")
public String userInfo(@RequestParam("code") String code,
                       @RequestParam("state") String returnUrl) throws Exception {
    
    System.out.println("code " + code);
    System.out.println("returnUrl " + returnUrl);
    //获取认证token
    WxOAuth2AccessToken accessToken = wxMpService.getOAuth2Service().getAccessToken(code);
    //从token中获取openId
    String openId = accessToken.getOpenId();


    //查找user表中是否存在该openId
    LambdaQueryWrapper<SysUser> lambdaQueryWrapper = new LambdaQueryWrapper<SysUser>();

bindPhone — 当成功授权后，如果微信号是第一次登录，需要提供窗口给用户用户手机号绑定

@ApiOperation(value = "微信账号绑定手机")
@PostMapping("/bindPhone")
@ResponseBody
public Result bindPhone(@RequestBody BindPhoneVo bindPhoneVo) {
    String phone = bindPhoneVo.getPhone();
    //查找user表中是否有当前记录

当然如果项目中配置了SpringSecurity 还需要在config中排除上述三个方法的路径

六、前端修改（基于vue）

前端的项目中主要修改两个地方，一个是src/App.vue 可以直接copy一下

<template>
  <div id="app">
    <router-view />
    <el-dialog title="绑定手机" :visible.sync="dialogVisible" width="80%" >
      <el-form ref="dataForm" :model="bindPhoneVo" size="small">
