阿里云上传
1. 导入阿里云上传SDK
2. 实例化阿里云
function initAliUpload() {
const uploader = new AliyunUpload.Vod({
timeout: $("#timeOut").val(),
// 上传视频的切片大小
partSize: $('#partSize').val(),
// 上传视频的并行切片个数
parallel: $('#parallel').val(),
// 上传失败重新上传的次数
retryCount: $('#retryCount').val(),
// 上传失败重新上传的间隔
retryDuration: $('#retryDuration').val(),
// 上传到点播的地域
region: $('#region').val(),
// 阿里账号 Id
userId: $('#userId').val(),
// 监听添加文件成功
addFileSuccess: function (uploadInfo) {
// console.log("addFileSuccess: " + uploadInfo.file.name)
layui.use("layer", function () {
const layer = layui.layer;
layer.msg("添加文件成功", {time: 2000})
})
},
// 监听开始上传
onUploadstarted: function (uploadInfo) {
console.log(uploadInfo);
// 如果videoId有值，根据videoId刷新上传凭证
if (!uploadInfo.videoId) {
var createUrl = '/front/aliyun/createUploadVideo';
$.get(createUrl, function (data) {
console.log(data);
var uploadAuth = data.UploadAuth
var uploadAddress = data.UploadAddress
var videoId = data.VideoId
videoId1 = data.VideoId;
// 设置作者以及地址
uploader.setUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress, videoId)
}, 'json');
// $('#status').text('文件开始上传...');
console.log("onUploadStarted:" + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object)
} else {
// 如果videoId有值，根据videoId刷新上传凭证
// https://help.aliyun.com/document_detail/55408.html?spm=a2c4g.11186623.6.630.BoYYcY
let refreshUrl = '/front/aliyun/refreshUploadVideo?videoId=' + uploadInfo.videoId;
$.get(refreshUrl, function (data) {
var uploadAuth = data.UploadAuth;
var uploadAddress = data.UploadAddress;
var videoId = data.VideoId;
videoId1 = data.VideoId;
// 设置作者以及地址
uploader.setUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress, videoId)
}, 'json')
}
},
// 文件上传成功
onUploadSucceed: function (uploadInfo) {
removeProgressBar();
swal({
type: "success",
title: "文件上传成功"
});
console.log(uploadInfo);

3. 使用阿里云上传实例
const videoEl = document.querySelector("#videos");
videoEl.addEventListener("change", function (e) {
const file = e.target.files[0];
// console.log(file);
if (!file) {
return false
}
// console.log(file.size);
let fileName = file.name;
let fileType = file.type;
let fileSize = file.size;
if (fileType.indexOf("mp4") === -1) {
swal({
type: "error",
title: "上传失败",
text: "请上传MP4类型的视频文件"
})
} else if (fileSize > 102400000) {
swal({
type: "error",
title: "上传失败",
text: "文件必须小于100M"
})
} else {
// 初始化 aliyun 上传
// 获取背景图片和第一帧视频图片作为背景资源
const videoUrl = URL.createObjectURL(file);
const videoEl = document.querySelector("#parseVideo");
let video, output;
const scale = 1.0;
videoEl.src = videoUrl;
videoEl.oncanplaythrough = function (ele) {
// console.log("视频的时长为: ");
// console.log(videoEl.duration);
var hour = parseInt((videoEl.duration) / 3600);
var minute = parseInt((videoEl.duration % 3600) / 60);
var second = Math.ceil(videoEl.duration % 60);
// console.log("这段视频的时长为："+hour+"小时，"+minute+"分，"+second+"秒");
let durationStr = hour + ":" + minute + ":" + second;
$("#videoDuration").val(durationStr)
};
const aliUploader = initAliUpload();
const result = aliUploader.addFile(file, null, null, null, userData); // 此处添加aliyun文件是一个同步的过程
if (result) {
// 开启自动上传
aliUploader.startUpload();
loadProgressBar();
} else {
swal({
type: "error",
title: "上传错误",
text: "aliyun添加文件列表异常"

}
}
});
