阿里云视频点播功能，客户端上传，javascript SDK 使用

阿里云文档地址：https://help.aliyun.com/document_detail/52204.html?spm=a2c4g.11174283.6.1041.60ce149bIGfVYM；

web端SDK上传demo地址：https://help.aliyun.com/document_detail/51992.html?spm=a2c4g.11186623.4.2.44256bd1scfNId，可以下载jquery和vue的使用示例；

上传地址和凭证方式(推荐使用)

第一步请求获取的上传地址和凭证初始化时无需设置，而是在开始上传开始后触发的onUploadStarted回调中调用setUploadAuthAndAddress(uploadFileInfo, uploadAuth, uploadAddress,videoId);方法进行设置。当token超时，会触发onUploadTokenExpired回调，需要调用resumeUploadWithAuth(uploadAuth)方法，设置新的上传凭证继续上传。

文档示例代码(javascript h5)：

1. var uploader = new AliyunUpload.Vod({
2. //阿里账号ID，必须有值 ，值的来源https://help.aliyun.com/knowledge_detail/37196.html
3. userId:"122"
4. //分片大小默认1M，不能小于100K
5. partSize: 1048576,
6. //并行上传分片个数，默认5
7. parallel: 5,
8. //网络原因失败时，重新上传次数，默认为3
9. retryCount: 3,
10. //网络原因失败时，重新上传间隔时间，默认为2秒
11. retryDuration: 2,
12. //是否上报上传日志到点播，默认为true
13. enableUploadProgress: true,
14. // 开始上传
15. 'onUploadstarted': function (uploadInfo) {
16. log("onUploadStarted:" + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
17. //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
18. if (uploadInfo.videoId) {
19. // 如果 uploadInfo.videoId 存在, 调用 刷新视频上传凭证接口(https://help.aliyun.com/document_detail/55408.html)
20. }
21. else{
22. // 如果 uploadInfo.videoId 不存在,调用 获取视频上传地址和凭证接口(https://help.aliyun.com/document_detail/55407.html)
23. }
24. //从点播服务获取的uploadAuth、uploadAddress和videoId,设置到SDK里
25. uploader.setUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress,videoId);
26. }
27. // 文件上传成功
28. 'onUploadSucceed': function (uploadInfo) {
29. log("onUploadSucceed: " + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
30. },
31. // 文件上传失败
32. 'onUploadFailed': function (uploadInfo, code, message) {
33. log("onUploadFailed: file:" + uploadInfo.file.name + ",code:" + code + ", message:" + message);
34. },
35. // 文件上传进度，单位：字节
36. 'onUploadProgress': function (uploadInfo, totalSize, loadedPercent) {
37. log("onUploadProgress:file:" + uploadInfo.file.name + ", fileSize:" + totalSize + ", percent:" + Math.ceil(loadedPercent * 100) + "%");
38. },
39. // 上传凭证超时
40. 'onUploadTokenExpired': function (uploadInfo) {
41. console.log("onUploadTokenExpired");
42. //实现时，根据uploadInfo.videoId调用刷新视频上传凭证接口重新获取UploadAuth
43. //https://help.aliyun.com/document_detail/55408.html
44. //从点播服务刷新的uploadAuth,设置到SDK里
46. uploader.resumeUploadWithAuth(uploadAuth);
47. },
48. //全部文件上传结束
49. 'onUploadEnd':function(uploadInfo){
50. console.log("onUploadEnd: uploaded all the files");
51. }

vue使用该方式的话，需要注意的几点：

1.引用问题

      (3)  使用的vue2.0,可以将下载的sdk正常引用；

      (2)  使用vue3.0的引用，在public文件夹下建立目录名称例如lib,将sdk放入该目录下，在index.html页面引用时，就是

   <script src="/lib/js/es6-promise.min.js"></script>

  <script src="/lib/js/aliyun-oss-sdk-5.3.1.min.js"></script>

  <script src="/lib/js/aliyun-upload-sdk-1.5.0.min.js"></script>

2.vue文件中的使用，来自demo：

<script>
