bolb:http 加密視訊路徑

後臺程式碼，僅需讀取檔案並變成二進位制流： /** * bolb 測試 */
public void getFile(HttpServletResponse response, HttpServletRequest request){ File f = new File("service-web/src/main/resources/static/images/video1.mp4"); String fileName = f.getName(); String agent = request.getHeader("User-Agent").toUpperCase(); InputStream fis = null; OutputStream os = null; try{ fis = new BufferedInputStream(new FileInputStream(f.getPath())); byte[] buffer; buffer = new byte[fis.available()]; fis.read(buffer); response.reset(); //由於火狐和其他瀏覽器顯示名稱的方式不相同，需要進行不同的編碼處理 if(agent.indexOf("FIREFOX") != -1){//火狐瀏覽器 response.addHeader("Content-Disposition", "attachment;filename="+ new String(fileName.getBytes("GB2312"),"ISO-8859-1")); }else{//其他瀏覽器 response.addHeader("Content-Disposition", "attachment;filename="+ URLEncoder.encode(fileName, "UTF-8")); } //設定response編碼 response.setCharacterEncoding("UTF-8"); response.addHeader("Content-Length", ""+ f.length()); //設定輸出檔案型別 response.setContentType("video/mpeg4"); //獲取response輸出流 os = response.getOutputStream(); // 輸出檔案 os.write(buffer); }catch(Exception e){ System.out.println(e.getMessage()); } finally { //關閉流 try { if (fis != null) { fis.close(); } } catch (IOException e) { System.out.println(e.getMessage()); } finally { try { if (os != null) { os.flush(); } } catch (IOException e) { System.out.println(e.getMessage()); } finally { try { if (os != null) { os.close(); } } catch (IOException e) { System.out.println(e.getMessage()); } } } } }
前臺接收程式碼：
function demoBlob() { //建立XMLHttpRequest物件 var xhr = new XMLHttpRequest(); //配置請求方式、請求地址以及是否同步 xhr.open('POST', '/getBolb', true); //設定請求結果型別為blob xhr.responseType = 'blob'; //請求成功回撥函式 xhr.onload = function (e) { if (this.status == 200) {//請求成功 //獲取blob物件 var blob = this.response; //獲取blob物件地址，並把值賦給容器 console.log("!_______________________________________________________________________________________________") console.log("加密後的視訊路徑："+URL.createObjectURL(blob)); console.log("!_______________________________________________________________________________________________") } }; xhr.send(); }
