videoInfo.wxml

<view style='width:100%;height:100%'>  <video id="myVideo" src="http://127.0.0.1:8081/180831CF2TS25MNC/4e0ca373-6520-45b9-a1a6-7ee8429dc5d8.mp4" muted='{{false}}' controls='{{false}}' autoplay='{{true}}' loop='{{true}}' enable-progress-gesture='{{false}}'  style='width:100%;height:100%;'  objectFit='{{cover}}'  >  <cover-view class='container'>            <!-- 上传视频 -->            <cover-image src='../../resource/images/camera.png' style='width:50rpx;height:50rpx;' bindtap='upload'></cover-image>            <!-- 搜索按钮 -->            <cover-image src='../../resource/images/search.png' style='width:45rpx;height:45rpx;' bindtap='showSearch'></cover-image>        </cover-view><cover-view class='container-me'>            <!-- 头像 -->            <cover-image class="face" src='{{serverUrl}}{{publisher.faceImage}}' bindtap='showPublisher'></cover-image>            <!-- 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>            <!-- 评论按钮 -->            <cover-image class="size-me" src='../../resource/images/comments.png' style='margin-top:30rpx;' bindtap='leaveComment'></cover-image>            <!-- 分享按钮 -->            <cover-image class="size-me" src='../../resource/images/share.png' style='margin-top:30rpx;' bindtap='shareMe'></cover-image>        </cover-view>      <cover-view class='container-words'>            <cover-view>@{{publisher.nickname}}</cover-view>            <cover-view class='video-desc'>{{videoInfo.videoDesc}}</cover-view>        </cover-view>        <cover-view class='container-bottom'>            <!-- 首页按钮 -->            <cover-image class='' src='../../resource/images/index.png' class="size-bottom" bindtap='showIndex'></cover-image>                      <!-- 我的按钮 -->            <cover-image class='' src='../../resource/images/mine.png' class="size-bottom" bindtap='showMine'></cover-image>        </cover-view>  </video></view>

videoInfo.js

Page({  data: {    cover:'cover',    videoContext:""  },  showSearch:function(){    wx.navigateTo({      url: '../videoSearch/videoSearch',    })  },  onLoad:function(){    var me = this;    me.videoContext = wx.createVideoContext('myVideo', me);  },  onShow:function(){    var me = this;    me.videoContext.play();  },  onHide:function(){    var me = this;    me.videoContext.pause();  }})

PS：小程序开发很类似app开发，了解生命周期，可以很方便的完成一些功能的开发。
