小程序的页面拦截

  当页面点击右下角的小图标后,触发showMain()事件,跳转到mine.wxml,展示个人信息页面,点击做下表的小房子跳转到视频首页

            <!-- 我的按钮 -->
<cover-image class='' src='../resource/images/mine.png' class="size-bottom" bindtap='showMine'></cover-image>

 

            <!-- 首页按钮 -->
            <cover-image class='' src='../resource/images/index.png' class="size-bottom" bindtap='showIndex'></cover-image>

 

  showIndex:function(){
    wx.redirectTo({
      url: '../index/index',
    })
  },

  showMine:function(){

    var user = app.getGlobalUserInfo();

    if(user ==null || user == undefined||user == ''){
      wx.navigateTo({
        url: '../userLogin/login',
      })
    }else{
      wx.navigateTo({
        url: '../mine/mine',
      })
    }
  }

 

  在api层添加MiniInterceptor.class对拦截器进行配置与注册

    //拦截请求,在controller调用之前
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
        if(true)
        {
            System.out.println("请求拦截...");
            return false;
        }
        
        //false:请求被拦截
        //true:放行请求
        return true;
    }

完善拦截并且限制用户只能在一台手机上登陆

  在加载个人页面mine.js的header中添加userId和userToken两个参数

      header: {
        'content-type': 'application/json', // 默认值
        'userId':user.id,
        'userToken':user.userToken
      },

 

  在MiniInterceptor.java中接收到小程序端传递的Header消息后进行拦截器的配置

//拦截请求,在controller调用之前
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
            Object handler)throws Exception {
        
        //获取来自小程序的两个参数
        String userId = request.getHeader("userId");
        String userToken  = request.getHeader("userToken");
        
        if(StringUtils.isNotBlank(userId)&&StringUtils.isNotBlank(userToken))
        {
            
            String uniqueToken = redis.get(USER_REDIS_SESSION + ":" + userId);
            if(StringUtils.isEmpty(uniqueToken)&&StringUtils.isBlank(uniqueToken)) {
                returnErrorResponse(response,new IMoocJSONResult().errorTokenMsg("请登录..."));
                return false;
            }else {
                if(!uniqueToken.equals(userToken)) {
                    returnErrorResponse(response,new IMoocJSONResult().errorTokenMsg("账号被挤出..."));
                    return false;
                }
            }
            
        }else{
            returnErrorResponse(response,new IMoocJSONResult().errorTokenMsg("请登录..."));
            return false;
        }
        
        //false:请求被拦截
        //true:放行请求
        return true;
    }

 

  要将后端控制台的消息返回给小程序端,需要用到returnErrorResponse(HttpServletResponse response, IMoocJSONResult result) 将消息转换成JSON数据格式,再传递给小程序端口

//转换成JSON数据格式
    public void returnErrorResponse(HttpServletResponse response, IMoocJSONResult result) 
            throws IOException, UnsupportedEncodingException {
        OutputStream out=null;
        try{
            response.setCharacterEncoding("utf-8");
            response.setContentType("text/json");
            out = response.getOutputStream();
            //抛出信息
            out.write(JsonUtils.objectToJson(result).getBytes("utf-8"));
            out.flush();
        } finally{
            if(out!=null){
                out.close();
            }
        }
    }

前后端联调测试拦截器

  注:IMoocJSONResult errorTokenMsg(String msg)方法返回的状态status是502

    public static IMoocJSONResult errorTokenMsg(String msg) {
        return new IMoocJSONResult(502, msg, null);
    }

 

  在微信小程序端进行状态吗的判断

if (res.data.status == 502){
          wx.showToast({
            title: res.data.msg,
            duration:3000,
            icon:"none",
            success:function(){
              wx.redirectTo({
                url: '../userLogin/login',
              })
            }

 

 

实现点赞与取消点赞功能前后端联调

  微信小程序点赞按钮前端模块

            <!-- 喜欢收藏按钮 -->
            <block wx:if="{{userLikeVideo}}">
                <cover-image class="size-me" src='../resource/images/like.png' style='margin-top:30rpx;' bindtap='likeVideoOrNot'></cover-image>
            </block>
            <block wx:else>
                <cover-image class="size-me" src='../resource/images/unlike.png' style='margin-top:30rpx;' bindtap='likeVideoOrNot'></cover-image>
            </block>

 

  VideosMapperCustom.java类中添加视频喜欢的数量方法

    //对视频喜欢的数量进行累加
    public void addVideoLikeCount(String videoId);
    
    //对视频喜欢的数量进行累减
    public void reduceVideoLikeCount(String videoId);

 

  VideosMapperCustom.xml中添加对数据库中进行查询的SQL语句

      <update  id="addVideoLikeCount" parameterType="String">
          update videos set like_counts = like_counts + 1 where id=#{videoId} 
      </update>

      <update  id="reduceVideoLikeCount" parameterType="String">
          update videos set like_counts = like_counts - 1 where id=#{videoId} 
      </update>

 

  同理UsersMapper.java中添加用户对视频是否喜欢

    //用户受喜欢数累加
    public void addReceiveLikeCount(String userId);
    
    //用户受喜欢数累减
    public void reduceReceiveLikeCount(String userId);
    

 

  在UsersMapper.xml中添加对数据库进行查询的语句

    <update  id="addReceiveLikeCount" parameterType="String">
          update users set receive_like_counts = receive_like_counts + 1 where id=#{userId} 
      </update>
  
     <update  id="reduceReceiveLikeCount" parameterType="String">
          update users set receive_like_counts = receive_like_counts - 1 where id=#{userId} 
      </update>

 

  Service层中添加删除用户和视频的喜欢和点赞关联表

    @Transactional(propagation = Propagation.REQUIRED)
    @Override
    public void userLikeVideo(String userId, String videoId, String videoCreateId) {
        
        //保存用户和视频的喜欢点赞关联关系表
        String likeId = sid.nextShort();
        UsersLikeVideos ulv = new UsersLikeVideos();
        ulv.setId(likeId);
        ulv.setUserId(userId);
        ulv.setVideoId(videoId);
        
        usersLikeVideosMapper.insert(ulv);
        
        //视频喜欢数量累加
        videosMapperCustom.addVideoLikeCount(videoId);
        
        //用户受喜欢数量的累加
        usersMapper.addReceiveLikeCount(userId);
        
    }

    @Transactional(propagation = Propagation.REQUIRED)
    @Override
    public void userUnLikeVideo(String userId, String videoId, String videoCreateId) {
        
        //1.删除用户和视频的喜欢点赞关联关系表
        
        Example example = new Example(UsersLikeVideos.class);
        Criteria criteria = example.createCriteria();
        
        criteria.andEqualTo("userId",userId);
        criteria.andEqualTo("videoId",videoId);
        
        usersLikeVideosMapper.deleteByExample(example);
        
        //视频喜欢数量累减
        videosMapperCustom.reduceVideoLikeCount(videoId);
        
        //用户受喜欢数量的累减
        usersMapper.reduceReceiveLikeCount(userId);
        
    }

  当用户对某一视频点赞后,数据库中后台会得到该用户与点赞视频对应的属性值与视频点赞数量

  

  

 

进入视频展示页面查询后端接口信息

   UserController.java中编写后端queryPublisher请求信息

@PostMapping("/queryPublisher")
    public IMoocJSONResult queryPublisher(String loginUserId,String videoId,
            String publishUserId) throws Exception {
        
            if(StringUtils.isBlank(publishUserId)) {
                return IMoocJSONResult.errorMsg("");
            }
        
            //查询视频发布者的信息
            Users  userInfo = userService.queryUserInfo(publishUserId);
            UsersVO publisher = new UsersVO();
            BeanUtils.copyProperties(userInfo, publisher);
            
            //查询当前登陆者和视频的点赞关系
            boolean userLikeVideo = userService.isUserLikeVideo(loginUserId, videoId);
            
            PublisherVideo bean = new PublisherVideo();
            bean.setPublisher(publisher);
            bean.setUserLikeVideo(userLikeVideo);
            
            return IMoocJSONResult.ok(bean);
    }

 

   videoindo.js中编写获得用户信息请求方法

 wx.request({
      url: serverUrl + '/user/queryPublisher?loginUserId=' + loginUserId + "&videoId=" + videoInfo.id +"&publishUserId="+videoInfo.userId,
      method:'POST',
      success:function(res){
        var publisher = res.data.data.publisher;
        var userLikeVideo = res.data.data.userLikeVideo;
      
        me.setData({
          serverUrl: serverUrl,
          publisher: publisher,
          userLikeVideo: userLikeVideo,
        });
      }
    })

  },

 

  进入index.js视频页面后,会展示该视频上传用户者头像及是否被当前用户点赞

 

var videoUtil = require('../../utils/videoUtil.js')

const app = getApp()

Page({
  data: {
    cover:"cover",
    videoId:"",

    videoInfo:{},
    userLikeVideo:false
  },

  videoCtx:{

  },

  onLoad:function(params){
    var me = this;
    me.videoCtx = wx.createVideoContext("myVideo", me);

    //获取上一个页面传入的参数
    var videoInfo = JSON.parse(params.videoInfo);
 
    var height = videoInfo.videoHeight;

关注于取消关注接口

  查看数据库中user表

  

 

   在UserMapper.java中编写增加粉丝数、增加关注数、减少粉丝数量、减少关注数量方法

    //增加粉丝数
    public void addFansCount(String userId);
    
    //增加关注数
    public void addFollersCount(String userId);
    
    //减少粉丝数量
    public void reduceFanCount(String userId);
    
    //减少关注数量
    public void reduceFollersCount(String userId);

  

  在UserMapper.xml中实现SQL语句的编写

     <!-- 粉丝  -->
      <update id="addFansCount" parameterType="String">
          update users set fans_counts = fans_counts + 1 where id=#{userId} 
      </update>
      
       <update id="reduceFanCount" parameterType="String">
          update users set fans_counts = fans_counts - 1 where id=#{userId} 
      </update>
      
      <!-- 关注度 -->
      <update id="addFollersCount" parameterType="String">
          update users set follow_counts = follow_counts + 1 where id=#{userId}

          update users set follow_counts = follow_counts - 1 where id=#{userId} 
      </update>
      

 

  Service层实现增加用户粉丝和减少用户粉丝方法

 

    @Transactional(propagation = Propagation.REQUIRED)

        userFan.setUserId(userId);
        userFan.setFanId(fanId);
        
        usersFansMapper.insert(userFan);

        userMapper.addFansCount(userId);
        userMapper.addFollersCount(fanId);
