使用的是JavaScript的方法去上传视频：选导入必要的js

https://help.aliyun.com/document_detail/51992.html?spm=a2c4g.11186623.2.41.71cd6bd1zmC1Gk#h2-web-sdk-3 我用的是1.5版本的

上jq代码：

` //视频上传到阿里云
    var uploader = new AliyunUpload.Vod({
                    //阿里账号ID，必须有值 ，值的来源https://help.aliyun.com/knowledge_detail/37196.html
                    //userId:"122",  **//这个当时我没写  也可以上传 我也不知道为什么  大佬可以说一下**
                    //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);
                              ~~var fileName=$("#file").val();
                              //判断上传类型
                              var fileType = fileName.substr(
                                      fileName.lastIndexOf(".")).toUpperCase();
                              if (fileType != ".MP4") {
                                  popup.alert.show("提示", "视频类型错误(请选择MP4格式)",
                                          function() {

后端代码 AccessKeyId 与AccessKeySecret 是必需的
