在使用vue做前端項(xiàng)目需求視頻直傳阿里云服務(wù)器
參考文檔（阿里云官方）
https://help.aliyun.com/docum...

導(dǎo)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) //獲取上傳權(quán)限
}

采用UploadAuthAndAddress上傳方式，后臺(tái)php獲取相關(guān)權(quán)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() //去上傳
    })
}

去上傳

videoUploadFn() {
    uploader.startUpload();
    _videoUploadSuccess.ok = false
    let interval = setInterval(() => {
        if(_videoUploadSuccess.ok) {
               clearInterval(interval)
               this.getVideoInfo() // 獲取視頻信息得到視頻封面圖片
          }
     , 10);
}

獲取視頻信息

getVideoInfo() {
    let sett 
    this.$post(`https://xxxx/ali/info.php`,{videoId :_videoUploadSuccess.uploadInfo.videoId}).then(res => {
         res = res.data
         xmview.showLoading("正在獲取縮略圖..")
         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 {
             // 這里加定時(shí)器，等待響應(yīng)
             sett = setTimeout(() => {
                 this.getVideoInfo()
             }, 3000);
         }               
    })
}

下面是sdk設(shè)置

var uploadAuth = ""
var uploadAddress = "" 
var videoId = ""
var _videoUploadSuccess = {
    ok: false,
    uploadInfo: {}
}
var _uploadprogress = 0 // 上傳進(jìn)度
const uploader = new AliyunUpload.Vod({
        //分片大小默認(rèn)1M，不能小于100K
        partSize: 1048576,
        //并行上傳分片個(gè)數(shù)，默認(rèn)5
        parallel: 5,
        //網(wǎng)絡(luò)原因失敗時(shí)，重新上傳次數(shù)，默認(rèn)為3
        retryCount: 3,
        //網(wǎng)絡(luò)原因失敗時(shí)，重新上傳間隔時(shí)間，默認(rèn)為2秒
        retryDuration: 2,
        // 開(kāi)始上傳
        "onUploadstarted": function(uploadInfo) {
            console.log("onUploadStarted:" + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
            //上傳方式1, 需要根據(jù)uploadInfo.videoId是否有值，調(diào)用點(diǎn)播的不同接口獲取uploadauth和uploadAddress，如果videoId有值，調(diào)用刷新視頻上傳憑證接口，否則調(diào)用創(chuàng)建視頻上傳憑證接口
            uploader.setUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress, videoId);
        },
        // 文件上傳成功
        "onUploadSucceed": function(uploadInfo) {
            _videoUploadSuccess.ok = true
            _videoUploadSuccess.uploadInfo = uploadInfo
            console.log("onUploadSucceed: " + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
        },
        // 文件上傳失敗
        "onUploadFailed": function(uploadInfo, code, message) {
            console.log("onUploadFailed: file:" + uploadInfo.file.name + ",code:" + code + ", message:" + message);
        },
        // 文件上傳進(jìn)度，單位：字節(jié)
        "onUploadProgress": function(uploadInfo, totalSize, loadedPercent) {
            _uploadprogress = Math.ceil(loadedPercent * 100)
            console.log("onUploadProgress:file:" + uploadInfo.file.name + ", fileSize:" + totalSize + ", percent:" + Math.ceil(loadedPercent * 100) + "%");
        },
        // 上傳憑證超時(shí)
        "onUploadTokenExpired": function(uploadInfo) {
            console.console.log("onUploadTokenExpired");
            //上傳方式1  實(shí)現(xiàn)時(shí)，根據(jù)uploadInfo.videoId調(diào)用刷新視頻上傳憑證接口重新獲取UploadAuth
            uploader.resumeUploadWithAuth(uploadAuth);
            // 上傳方式2 實(shí)現(xiàn)時(shí)，從新獲取STS臨時(shí)賬號(hào)用于恢復(fù)上傳
            // uploader.resumeUploadWithSTSToken(accessKeyId, accessKeySecret, secretToken, expireTime);
        },
        //全部文件上傳結(jié)束
        "onUploadEnd": function(uploadInfo) {
            console.log("onUploadEnd: uploaded all the files");
        }
    });
    const userData = "{"Vod":{"UserData":{"IsShowWaterMark":"false","Priority":"7"}}}"
