首页视频列表-上拉分页

　　小程序使用上拉刷新方法onReachBottom()

　　封装显示视频方法getAllVideoList()

 getAllVideoList:function(page){

      title: '请等待，加载中...',
    })

    wx.request({

        if (page == 1) {
          me.setData({
            videoList: []
          });
        }

        var videoList = res.data.data.rows;
        var newVideoList = me.data.videoList;

        me.setData({

          serverUrl: serverUrl
        });

      }
    })

视频组件与api

　　muted：设置video组件是否有声音

　　initial-time：指定视频初始播放位置

　　direction：设置全屏时视频的方向，不指定则根据宽高比自动判断

　　controls：是否显示默认播放控件（播放/暂停按钮、播放进度、时间）

　　duration：指定视频时长

　　danmu-list：弹幕列表

　　enable-danmu：是否展示弹幕，只在初始化时有效，不能动态变更

　　danmu-btn：是否显示弹幕按钮，只在初始化时有效，不能动态变更

　　autoplay：是否自动播放

　　loop：是否循环播放

　　page-gesture：在非全屏模式下，是否开启亮度与音量调节手势（废弃，见 vslide-gesture）

　　direction：设置全屏时视频的方向，不指定则根据宽高比自动判断

开源搜索视频组件的使用

　　使用开源视频组件 github传送门

searchVideo.wxml

<include src="../../wxSearchView/wxSearchView.wxml" />

searchVideo.wxss

// 1 导入js文件
var WxSearch = require('../../wxSearchView/wxSearchView.js');

searchVideo.js

修改全局用户对象使用缓存

　　在app.js中添加两个方法

//设置全局用户对象
  setGlobalUserInfo:function(user){
    wx.setStorageSync("userInfo", user)
  },

//获取全局用户对象
  getGlobalUserInfo: function () {
    return wx.getStorageSync("userInfo")
  }

　　修改app.userInfo中的值

查询接口完善以及热搜词搜索

　　开发查询接口和热搜词接口

//分页和搜索查询视频列表
    //isSaveRecord：1  需要保存  0  不需要保存或为空
    @PostMapping(value="/showAll")
    public IMoocJSONResult showAll(@RequestBody Videos video,Integer isSaveRecord ,
            Integer page) throws Exception {
        
        if(page == null) {
            page = 1;
        }
        
        PagedResult result = videoService.getAllVideos(video,isSaveRecord,page,PAGE_SIZE);
        return IMoocJSONResult.ok(result);
        
    }
    
    
    @PostMapping(value="/hot")
    public IMoocJSONResult hot() throws Exception {
        
        return IMoocJSONResult.ok(videoService.getHotwords());
    }

　　VideoServiceImpl视频热搜词方法getHotwords()

    @Transactional(propagation = Propagation.SUPPORTS)
    @Override
    public List<String> getHotwords() {
        
        return searchRecordsMapper.getHotwords();
    }

　　往数据库中添加一些假数据Gary数据有4条，perfect数据有2条，school数据有1条，热搜词搜索后，数据将从Gary->perfect->school顺序进行排序

　　在searchVideo.js中进行小程序前后端连调

videoinfo.js

首页进入视频展示页

　　在videoInfo.js添加showVideoInfo()方法，当用户点击图片时候触发showVideoInfo()方法

<image src="{{serverUrl}}{{item.coverPath}}" style='width:{{screenWidth}}px;height:210px;' mode="aspectFit" bindtap='showVideoInfo' data-arrindex='{{index}}'></image>

  showVideoInfo:function(e){
      var me = this;
      var videoList = me.data.videoList;
      var arrindex = e.target.dataset.arrindex;
    var videoInfo = JSON.stringify(videoList[arrindex]);

    wx.redirectTo({
      url: '../videoinfo/videoinfo?videoInfo='+videoInfo,
    })
  }

　　在videoInfo.js中的onload()接收来自index.js中的值

  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);
    me.setData({
      videoInfo: videoInfo.id,
      src:app.serverUrl + videoInfo.videoPath,
      videoInfo: videoInfo
    });
  },

const app = getApp()

Page({
  data: {
    // 用于分页的属性
    totalPage:1,
    page:1,
    videoList:[],
    screenWidth: 350,
    //用于展示图片
    serverUrl:"",
    searchContent:""
  },

  onLoad: function (params) {
    var me = this;
    var screenWidth = wx.getSystemInfoSync().screenWidth;

    me.setData({
      screenWidth: screenWidth,
    });

    var searchContent = params.search;
    var isSaveRecord = params.isSaveRecord;
    if (isSaveRecord == null || isSaveRecord == '' || isSaveRecord==undefined){
      isSaveRecord = 0;
    }

    me.setData({
      searchContent: searchContent
    });

    //获取当前的分页数
    var page = me.data.page;
    me.getAllVideoList(page, isSaveRecord);
  },

  getAllVideoList: function (page, isSaveRecord){
    var me = this;
    var serverUrl = app.serverUrl;
    wx.showLoading({

      success: function (res) {
        wx.hideLoading();
        wx.hideNavigationBarLoading();
        //停止当前页面下拉刷新
        wx.stopPullDownRefresh();

        console.log(res.data);
        //判断当前页面page是否是第一页，如果是第一页，那么设置videoList为空
        if (page == 1) {
          me.setData({

          });

          totalPage: res.data.data.total,
          serverUrl: serverUrl
        });

      }
    })
  },

  onPullDownRefresh:function(){
    wx.showNavigationBarLoading()
    this.getAllVideoList(1,0);
  },

  onReachBottom:function(){

        icon:"none"
      })
      return ;
    }

    var page = currentPage + 1;

    me.getAllVideoList(page,0);
  },

  showVideoInfo:function(e){
      var me = this;

　　为增强用户体验，实现用户上传视频时候横竖屏的转换

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);
