阿里雲視頻點播功能，客戶端上傳，javascript SDK 使用

阿里雲文檔地址：https://help.aliyun.com/document_detail/52204.html?spm=a2c4g.11174283.6.1041.60ce149bIGfVYM；

web端SDK上傳demo地址：https://help.aliyun.com/document_detail/51992.html?spm=a2c4g.11186623.4.2.44256bd1scfNId，能夠下載jquery和vue的使用示例；

 

上傳地址和憑證方式(推薦使用)

第一步請求獲取的上傳地址和憑證初始化時無需設置，而是在開始上傳開始後觸發的onUploadStarted回調中調用setUploadAuthAndAddress(uploadFileInfo, uploadAuth, uploadAddress,videoId);方法進行設置。當token超時，會觸發onUploadTokenExpired回調，須要調用resumeUploadWithAuth(uploadAuth)方法，設置新的上傳憑證繼續上傳。

文檔示例代碼(javascript h5)：

1. var uploader = new AliyunUpload.Vod({
2. //阿里帳號ID，必須有值 ，值的來源https://help.aliyun.com/knowledge_detail/37196.html
3. userId:"122"
4. //分片大小默認1M，不能小於100K
5. partSize: 1048576,
6. //並行上傳分片個數，默認5
7. parallel: 5,
8. //網絡緣由失敗時，從新上傳次數，默認爲3
9. retryCount: 3,
10. //網絡緣由失敗時，從新上傳間隔時間，默認爲2秒
11. retryDuration: 2,
12. //是否上報上傳日誌到點播，默認爲true
13. enableUploadProgress: true,
14. // 開始上傳
15. 'onUploadstarted': function (uploadInfo) {
16. log("onUploadStarted:" + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
17. //上傳方式1, 須要根據uploadInfo.videoId是否有值，調用點播的不一樣接口獲取uploadauth和uploadAddress，若是videoId有值，調用刷新視頻上傳憑證接口，不然調用建立視頻上傳憑證接口
18. if (uploadInfo.videoId) {
19. // 若是 uploadInfo.videoId 存在, 調用 刷新視頻上傳憑證接口(https://help.aliyun.com/document_detail/55408.html)
20. }
21. else{
22. // 若是 uploadInfo.videoId 不存在,調用 獲取視頻上傳地址和憑證接口(https://help.aliyun.com/document_detail/55407.html)
23. }
24. //從點播服務獲取的uploadAuth、uploadAddress和videoId,設置到SDK裏
25. uploader.setUploadAuthAndAddress(uploadInfo, uploadAuth, uploadAddress,videoId);
26. }
27. // 文件上傳成功
28. 'onUploadSucceed': function (uploadInfo) {
29. log("onUploadSucceed: " + uploadInfo.file.name + ", endpoint:" + uploadInfo.endpoint + ", bucket:" + uploadInfo.bucket + ", object:" + uploadInfo.object);
30. },
31. // 文件上傳失敗
32. 'onUploadFailed': function (uploadInfo, code, message) {
33. log("onUploadFailed: file:" + uploadInfo.file.name + ",code:" + code + ", message:" + message);
34. },
35. // 文件上傳進度，單位：字節
36. 'onUploadProgress': function (uploadInfo, totalSize, loadedPercent) {
37. log("onUploadProgress:file:" + uploadInfo.file.name + ", fileSize:" + totalSize + ", percent:" + Math.ceil(loadedPercent * 100) + "%");
38. },
39. // 上傳憑證超時
40. 'onUploadTokenExpired': function (uploadInfo) {
41. console.log("onUploadTokenExpired");
42. //實現時，根據uploadInfo.videoId調用刷新視頻上傳憑證接口從新獲取UploadAuth
43. //https://help.aliyun.com/document_detail/55408.html
44. //從點播服務刷新的uploadAuth,設置到SDK裏
46. uploader.resumeUploadWithAuth(uploadAuth);
47. },
48. //所有文件上傳結束
49. 'onUploadEnd':function(uploadInfo){
50. console.log("onUploadEnd: uploaded all the files");
51. }

vue使用該方式的話，須要注意的幾點：

1.引用問題

      (3)  使用的vue2.0,能夠將下載的sdk正常引用；

      (2)  使用vue3.0的引用，在public文件夾下創建目錄名稱例如lib,將sdk放入該目錄下，在index.html頁面引用時，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，來自demo：

<script>
