靠近阿里云--视频点播

摘要：在使用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导入官方的事件获取上传权限采用上传方式，后台获取相关权限去上传去上传获取视频信息得到视频封面图片获取视频信息正在获取缩略图这里加定时器，等待响应下面是设置上传进度分片大小

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

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"}}}"
