Method and system for hiding media URI (Uniform Resource Identifier) in CDN (Content Delivery Network) and terminal

The disclosure relates to a method and a system for hiding a media URI (Uniform Resource Identifier) in a CDN (Content Delivery Network) and a terminal. The method comprises the following steps: requesting the playing address of media to be played from a playing address generating module; receiving an encrypted playing address, and forwarding the encrypted playing address to the CDN through a playing list request; receiving a playing list file returned by the CDN, wherein the playing list file comprises the URI of each fragment of encrypted requested media; requesting a media file from the CDN, wherein a request of the media file comprises the URI of each fragment of the encrypted requested media; and receiving the media file returned by the CDN. Through adoption of the method and the system, the media URI can be hidden when an HAS (HTTP Adaptive Streaming) mechanism is adopted.
