Suitable for some viewing numbers are few, needs mandate logs in and the website to preventing download from requiring.But for video provider
But it can realize that there is very high practicability into original with relatively low.When building the play system, streaming media service used
Device for example can be Nginx video servers, and video flow host-host protocol is rtmp;Correspondingly, the Streaming Media control program example
The nginx-rtmp Streaming Media plug-in units compiled in this way, the token proving programs are based on ngx_http_lua_module modules
The Lua shell scripts of exploitation.It is of course also possible to using other streaming media servers and other transport protocols, as long as server is matched
It is equipped with the Streaming Media control program that there is identical function with the present invention and token proving programs.It is assisted below with being based on rtmp
It is next for the Nginx video servers of view that the present invention is further illustrated.
With reference to figure 1, the workflow of the above-mentioned online play system of web video that can prevent from downloading is, for example,:
First, client open play the page, at this time server end can know client User ID and log in when
Between the information such as stamp, server is according to User ID at this time and timestamp or even also while some keys according to user, dynamic IP
Etc. information, carry out the unique token parameters of real-time operation one, distribute to client;Client is after the broadcasting page is opened, immediately
Video can be asked to server, that is, send URL, URL carries the real-time token parameters that server has just distributed at this time.Wherein,
The User ID is that the authorized user for playing the page logs in ID used during the broadcasting page.Ask the URL's of video
Form is, for example, rtmp://evideo.km.netease.com/vod/pt/2016/20161220144329_
wrewxs.mp4, the URL that real-time token parameters are carried in the embodiment of the present invention is, for example, rtmp://
evideo.km.netease.com/vod/pt/2016/20161220144329_wrewxs.mp4Token=
eqpAdfqpA8uHfa7338d2c3FEGc46be34b0da9OOvB8KWVxtB95FS53.The operation of URL is sent to server
Can be that click specific button for example " starts to play " after opening the broadcasting page, then client adds in real-time token parameters
It is sent to server end together into URL;Can also be that client player carries real-time token parameters transmission URL extremely automatically
Server end.
When server end has received the video request URL for carrying real-time token parameters of client transmission, to wherein
Real-time token parameters carry out validation verification.In the present embodiment, using the ngx_http_lua_ based on Nginx servers
Module Development of Module one Lua shell scripts verify the validity of the real-time token parameters, for example, by with server end
All token parameters received before this in database are compared to verify, join if existing in database with the real-time token
The same token parameters of number, then judge the real-time token invalid parameters;If there are same token ginsengs in database
Number, then judge that the real-time token parameters are effective.That is, server can only be used every time to the token parameters of client distribution
Once.It is of course also possible to use other manner verifies token m odel validities, the present invention is not limited thereto.
When judging that real-time token parameters are effective, the present invention is compiled into the nginx-rtmp Streaming Medias in Nginx servers
Plug-in unit starts to client transmissions video flowing, and client player just starts to play video, while server record client is broadcast
Put link information;Conversely, the Streaming Media plug-in unit will not can not play video to client transmissions video, player.
After video starts broadcasting, client can at regular intervals (time interval can be it is uniform or
It is non-uniform) broadcasting validity is verified with regard to the broadcasting verification interface (i.e. described middle verification program) at invoking server end.Example
Such as, start to play after ten minutes, play one verification frame of pop-up in some region of the page, for example be slidable puzzle, mathematical operation
Deng, at this time must user could be verified by operating mouse.If the verification passes, then continue to play;If verification is obstructed
It crosses, then by calling the drop methods of nginx-rtmp Streaming Media plug-in units, stops into the broadcasting link information of precedence record
Client transmissions video, middle connection breaking, it is therefore prevented that certain plug-in units intercept and capture broadcast address and token parameters to play and cache automatically
Video.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, it is impossible to assert
The specific implementation of the present invention is confined to these explanations.For those skilled in the art to which the present invention belongs, it is not taking off
