检查视频的地址

<view class="" v-if="urlVideo!=''">
    				<video :src="urlVideo" controls autoplay="true"></video>
    			</view>
    
    
    
    <script>
    
    import checkMPUrl from '../../../common/checkmp4.js'
    
    
    onload:方法
    
    			if (that.content.indexOf('video') !== -1) {
    				if (that.content.indexOf('.mp4') !== -1)
    					this.urlVideo = that.content.substring(that.content.indexOf('src') + 5, that.content.indexOf('mp4') + 3)
    					// this.urlVideo ='http://wxsnsdy.tc.qq.com/105/20210/snsdyvideodownload?filekey=30280201010421301f0201690402534804102ca905ce620b1241b726bc41dcff44e00204012882540400&bizid=1023&hy=SH&fileparam=302c020101042530230204136ffd93020457e3c4ff02024ef202031e8d7f02030f42400204045a320a0201000400'
    
    				console.log("视频地址:", urlVideo)
    				if (checkMPUrl(this.urlVideo) != 200) {
    					uni.showToast({
    						title: "该视屏无法播放",
    						icon: 'none'
    					})
    				}
    			} else {
    				this.urlVideo = "";
    			}
