推荐答案

可以有很多方法可以做到这一点.一种简单的方法是，您可以使用您只知道的隐藏密钥，该密钥只​​有通过加密才能验证音频/视频请求是通过内部代码进行的.现在，允许读取代码并将其显示给用户，但是如果用户尝试，则他们将无法传递额外的隐藏密钥以及下载请求，因此它们将被拒绝.

There can be number of ways to do that. One simple way would be, you can use a hidden key known to you only might be encrypted that authenticates that the audio/video request is by code internally. Now code is allowed to read and display the same to users, but if user tried they wont be able to pass an extra hidden key along with request to download and hence they are denied.
