如何防止视频连接被获取
正常模式下,在中直接使用了视频的地址,比如:movie.mp4。这样通过查看源代码或者F12能很快的定位到视频的全路径地址,那么如何控制视频地址不对外展示呢?
前端编写似乎还,不要暴露mp4等视频地址,编写方式如下:
视频地址换成后台请求地址,请求后台根据传入的id查询出对应的视频信息,将视频信息通过response流的模式写出,代码如下:
@RequestMapping("/getVideo/{id}")
public void getVideo(HttpServletRequest request,HttpServletResponse response,@PathVariable String id){
//视频资源存储信息
PageData pd = new PageData();
pd.put("id",id);
PageData filePd = sourceService.findVideoInfo(pd);
response.reset();
//获取从那个字节开始读取文件
String rangeString = request.getHeader("Range");
try {
//获取响应的输出流
OutputStream outputStream = response.getOutputStream();
File file = new File(ParaUtil.localName+filePd.get("file_path").toString());
if(file.exists()){
RandomAccessFile targetFile = new RandomAccessFile(file, "r");
long fileLength = targetFile.length();
//播放
if(rangeString != null){
long range = Long.valueOf(rangeString.substring(rangeString.indexOf("=") + 1, rangeString.indexOf("-")));
//设置内容类型
response.setHeader("Content-Type", "video/mp4");
//设置此次相应返回的数据长度
response.setHeader("Content-Length", String.valueOf(fileLength - range));
//设置此次相应返回的数据范围
response.setHeader("Content-Range", "bytes "+range+"-"+(fileLength-1)+"/"+fileLength);
//返回码需要为206,而不是200
response.setStatus(HttpServletResponse.SC_PARTIAL_CONTENT);
//设定文件读取开始位置(以字节为单位)
targetFile.seek(range);
}else {//下载
//设置响应头,把文件名字设置好
response.setHeader("Content-Disposition", "attachment; filename="+filePd.get("name"));
//设置文件长度
response.setHeader("Content-Length", String.valueOf(fileLength));
//解决编码问题
response.setHeader("Content-Type","application/octet-stream");
}
byte[] cache = new byte[1024 * 300];
int flag;
while ((flag = targetFile.read(cache))!=-1){
outputStream.write(cache, 0, flag);
}
}else {
String message = "file:"+filePd.get("name")+" not exists";
//解决编码问题
response.setHeader("Content-Type","application/json");
outputStream.write(message.getBytes(StandardCharsets.UTF_8));
}
outputStream.flush();
outputStream.close();
} catch (FileNotFoundException e) {
} catch (IOException e) {
}
}
视频意外流失,如何控制视频不被传播
在我们实际运营过程中,可能会存在视频被流失的风险,一旦视频流失可能会对企业造成很大的影响,那么如何避免视频被流出呢?
通过java对视频流进行加解密处理,及时视频外流,也无法对视频进行播放。
