The data capture method of the embodiment of the present invention can apply multiple fields, such as video field to play view for requesting
Frequently, field of play request game article, financing field request financial product illustrate information etc..
Preferred embodiment below will be described in detail so that the present invention is applied to video field as an example.
The present invention also provides a kind of preferred embodiment, the preferred embodiment provides a kind of dynamic based on varnish
Reverse proxy method.
Before this preferred embodiment is introduced, theory explained below is carried out to the technical term being directed to first
It is bright:
Varnish: one open source http cache server acts on behalf of and caches number in this programme for realizing dynamic direction
According to.
It is used to indicate a structural body of back-end content server in backend_hint:varnish configuration file, including
IP and port.
Backend: the back-end content server of varnish reverse proxy is indicated.
C language structural body corresponding with backend_hint in struct director:varnish module.
Exempt to flow: user requests particular flow rate using mobile cellular network, and operator does not collect traffic fee.
Hui Yuan: Reverse Proxy is forwarded to rear end in locally data requested without user, user's request
Content server retracts requested data and is transmitted to the process of user.
This method is based on open source varnish project and realizes a kind of dynamic reverse proxy service.Usual varnish is for acting on behalf of
One fixed or a collection of content server forwards the request to the corresponding content server in rear end simultaneously when user's request reaches
Cache the data that rear end returns.
Varnish, varnish are arrived first in the request that video on demand exempts to open the client for exempting from stream business in stream project
Mainly as the cache server of program request file, if there is no the data varnish of request to need Hui Yuan in caching, here
Varnish acts as the role of reverse proxy.The content of reverse proxy is the on-demand content of different clients in video cloud, access
URL and parameter etc. are different because of different clients.
This method is based on open source varnish project, proposes that a kind of reverse proxy of optimization is realized, can be with dynamic proxy difference
Back-end content server, avoid in configuration file largely pre-defining rear end list, when back-end content server has altered
When, without changing configuration file.Varnish configuration and O&M risk can effectively be simplified, third party's client is facilitated to access.
This method can be used for video cloud program request and exempt from stream project, and varnish deployment IP is the white name cooperated operator and exempt from stream
Single IP does not collect traffic fee to user by the traffic carriers of these IP.Before this method makes varnish dynamic reverse proxy
The different requests that end reaches according to user request information dynamic analysis URL and find corresponding contents server pull data to originally
Ground, to greatly simplify configuration and the O&M of varnish.
As shown in figure 3, the complete procedure of varnish request may include:
(1) client clinet sends request req to varnish.
(2) varnish construction request bereq accesses back-end content server backend and retracts data beresp.
(3) the data cached beresp of varnish is to local memory.
(4) varnish is to client clinet respond request content resp.
This programme general thought is the URL format for defining third party client's request, makes to carry back-end content in request URL
The URL of server.Then corresponding parsing function is realized in varnish configuration script, enables configuration script from request URL
The information of middle parsing back-end content server simultaneously constructs the distinctive backend data format of varnish.Finally request URL is substituted for
The true content server URL in rear end simultaneously forwards request, and request terminates then releasing memory resource.
The specific implementation flow of this method is as shown in figure 4, may comprise steps of:
Step S401 searches true domain name and port.
Step S402, domain name mapping obtain IP and port.
Step S403 uses varnish structure structural texture body struct director.
Step S404, judges whether structural body is successfully constructed, if successfully thening follow the steps S405；Otherwise terminate.
Structural body struct director is assigned to backend_hint by step S405.
Step S406 uses real URL replacement request URL.
Step S407 uses backend_hint to rear end request data.
Step S408, judges whether request data succeeds, if it succeeds, executing step S409, discharges structural body
Then struct director executes step S410, cache and to client returned data；If it fails, then executing
Step S409 discharges structural body struct director.
For above-mentioned steps it should be understood that
The format for defining user's request URL makes to reach the ground that back-end content server is carried in the request URL of varnish
Location information.URL citing:
Http:// test.vodflowproxy.myqcloud.com/live/test.mp4? sourceUrl=
http://6000.liveplay.myqcloud.com/live/68l6U8ck8Hg.mp4
It should be noted that eliminating the incoherent information of this programme such as authorization check in this URL, only retain and our
The relevant reverse proxy of case and URL information.Wherein, " test.vodflowproxy.myqcloud.com " is to exempt from basin name, the
Tripartite's client request exempts from stream service by this domain name request, and request can be sent to varnish server；"/live/
Test.mp4 " is that this document is buffered in the index key used when varnish；The URL of sourceUrl institute band is true rear end
Request URL.
Does is default treatment mode that rear end request URL is set to "/live/test.mp4 after varnish receives above-mentioned URL?
SourceUrl=http: // 6000.liveplay.myqcloud.com/live/68l6U8ck8Hg.mp4 ", then configuring
Suitable backend is found in file and forwards request.Therefore need to extend the default treatment ability of varnish, i.e., "/
Live/test.mp4? sourceUrl=http: // 6000.liveplay.myqcloud.com/live/
68l6U8ck8Hg.mp4 " is parsed, and obtains key (/live/test.mp4), rear end backend when caching respectively
(6000.liveplay.myqcloud.com), rear end request URL (/live/68l6U8ck8Hg.mp4) are then rewritten and are corresponded to
Field, then carry out Hui Yuan.
The key of caching, rear end request URL have had corresponding variable to indicate and be all word in the configuration file of default
String type is accorded with, so directly rewriting.And the mode of rear end backend default is a knot for being previously defined in configuration file
Structure body is simultaneously expressed as backend_hint, and can not field indirect assignment to this structural body in configuration script.So
Next it needs to construct backend_hint. according to request URL
In configuration file backend_hint actually it is corresponding be C language code struct director.Therefore originally
Scheme is by way of extending varnish physical layer interface ability come dynamic construction and release struct director.Specifically
SourceUrl parameter value is passed to self defined interface by ground；Self defined interface, which parses, comes into the domain name (or IP) come and port；
Domain name mapping is carried out if what is parsed is domain name to obtain IP；Varnish internal interface is based on using IP and port
Construction struct director simultaneously returns to its pointer.
The pointer of struct director can freely use after returning to configuration script in configuration script, still
Since struct director is dynamic application memory, so also needing to realize connecing for a release struct director
Mouthful.It is achieved in that in configuration script and struct director is passed to customized realizing interface, customized realizing interface base
The corresponding memory of structdirector is deleted in varnish internal interface, to prevent memory overflow.
This programme, which is equivalent to, is converted to dynamic analysis static configuration, to simplify the complexity of configuration file.
From the point of view of scheme itself, the configuration for needing to configure thousands of a backend and if-else branches originally can be with
It is reduced to code block as shown in Figure 5.Even if subsequent increase client or client's backend arrangement have change, it is all not necessarily to varnish
Do configuration change, it is only necessary to above-mentioned URL rules modification request URL in client request, to greatly reduce project dimension
Protect cost and O&M risk.
Based on this scheme can fast implement program request exempt from stream and acceleration function, convenient for third party's client popularization and
Attract potential user.To help third party's client quickly to occupy market catbird seat.
It should be noted that varnish has functioned simultaneously as the role of reverse proxy and cache server in this programme.Reversely
The open source realization of agency have it is very much, such as nginx, but nginx in the ability for realizing local cache not as good as varnish flexibly and specially
Industry.So can also realize this programme in conjunction with nginx and varnish, i.e. for varnish for caching, nginx is used for reversed generation
Reason, architecture diagram are as shown in Figure 6.
It should be noted that for the various method embodiments described above, for simple description, therefore, it is stated as a series of
Combination of actions, but those skilled in the art should understand that, the present invention is not limited by the sequence of acts described because
