靠近阿里云--视频点播

在使用vue做前端项目需求视频直传阿里云服务器
参考文档（阿里云官方）
https://help.aliyun.com/docum...

导入官方sdk

<script src="/static/aliyun/aliyun-oss-sdk-5.2.0.min.js"></script>
<script src="/static/aliyun/aliyun-upload-sdk-1.4.0.min.js"></script>

input的@change事件

change(event) {
     let file = event.target.files[0]
     let url = URL.createObjectURL(file)
     this.getVideoUploadAuth(file) //获取上传权限
}

采用UploadAuthAndAddress上传方式，后台php获取相关权限

getVideoUploadAuth(file) {
    let path = document.getElementById('file').value
    let params = {
        video_title: file.name,
        video_url: path
    }
    axios.post('https://xxx/aliapi/upload.php', params).then(res => {
        uploadAuth = res.data.UploadAuth
        uploadAddress = res.data.UploadAddress
        videoId = res.data.VideoId
        uploader.addFile(file, null, null, null, userData);
        this.videoUploadFn() //去上传
    })
}

去上传

videoUploadFn() {
    uploader.startUpload();
    _videoUploadSuccess.ok = false
    let interval = setInterval(() => {
        if(_videoUploadSuccess.ok) {
               clearInterval(interval)
               this.getVideoInfo() // 获取视频信息得到视频封面图片
          }
     , 10);
}

获取视频信息

getVideoInfo() {
    let sett 
    this.$post(`https://xxxx/ali/info.php`,{videoId :_videoUploadSuccess.uploadInfo.videoId}).then(res => {
         res = res.data
         xmview.showLoading('正在获取缩略图..')
         if (res.Video.CoverURL) {
             this.posterimg = res.Video.CoverURL
             sessionStorage.setItem('video_content',_videoUploadSuccess.uploadInfo.videoId)
             sessionStorage.setItem('video_thumb',res.Video.CoverURL)
             xmview.hideLoading()
             clearTimeout(sett)
         } else {
             // 这里加定时器，等待响应
             sett = setTimeout(() => {
                 this.getVideoInfo()
             }, 3000);
         }               
    })
}

下面是sdk设置

var uploadAuth = ''
var uploadAddress = '' 
var videoId = ''
var _videoUploadSuccess = {
    ok: false,
    uploadInfo: {}
}
var _uploadprogress = 0 // 上传进度
const uploader = new AliyunUpload.Vod({
        //分片大小默认1M，不能小于100K
        partSize: 1048576,
        //并行上传分片个数，默认5
        parallel: 5,
        //网络原因失败时，重新上传次数，默认为3
        retryCount: 3,
        //网络原因失败时，重新上传间隔时间，默认为2秒
        retryDuration: 2,
        // 开始上传
        'onUploadstarted': function(uploadInfo) {
            console.log("onUploadStarted:" + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
            //上传方式1, 需要根据uploadInfo.videoId是否有值，调用点播的不同接口获取uploadauth和uploadAddress，如果videoId有值，调用刷新视频上传凭证接口，否则调用创建视频上传凭证接口
            uploader.setUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress, videoId);
        },
        // 文件上传成功
        'onUploadSucceed': function(uploadInfo) {
            _videoUploadSuccess.ok = true
            _videoUploadSuccess.uploadInfo = uploadInfo
            console.log("onUploadSucceed: " + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
        },
        // 文件上传失败
        'onUploadFailed': function(uploadInfo, code, message) {
            console.log("onUploadFailed: file:" + uploadInfo.file.name + ",code:" + code + ", message:" + message);
        },
        // 文件上传进度，单位：字节
        'onUploadProgress': function(uploadInfo, totalSize, loadedPercent) {
            _uploadprogress = Math.ceil(loadedPercent * 100)
            console.log("onUploadProgress:file:" + uploadInfo.file.name + ", fileSize:" + totalSize + ", percent:" + Math.ceil(loadedPercent * 100) + "%");
        },
        // 上传凭证超时
        'onUploadTokenExpired': function(uploadInfo) {
            console.console.log("onUploadTokenExpired");
            //上传方式1  实现时，根据uploadInfo.videoId调用刷新视频上传凭证接口重新获取UploadAuth
            uploader.resumeUploadWithAuth(uploadAuth);
            // 上传方式2 实现时，从新获取STS临时账号用于恢复上传
            // uploader.resumeUploadWithSTSToken(accessKeyId, accessKeySecret, secretToken, expireTime);
        },
        //全部文件上传结束
        'onUploadEnd': function(uploadInfo) {
            console.log("onUploadEnd: uploaded all the files");
        }
    });
    const userData = '{"Vod":{"UserData":{"IsShowWaterMark":"false","Priority":"7"}}}'
