Abstract
The present invention relates to a kind of data compression method, more particularly to a kind of HTTP data compression method of use key frame compression.A kind of HTTP data compression method of use key frame compression of the invention, it can be according to the difference of setting suffix name, classified compression is carried out for crucial data framing, can be using canonical algorithms such as common ZIP compressions, data are transferred to browser end according to different situations, can respectively be decompressed according to the difference of suffix name.
Description
Technical field
The present invention relates to a kind of data compression method, more particularly to a kind of HTTP of use key frame compression
Data compression method.
Background technology
HTTP（HTTP）It is a kind of procotol being most widely used on internet.All of internet
File must comply with this standard.Design HTTP initial purpose is to provide for a kind of side for issuing and receiving html page
Method.Nineteen sixty American Ted Nelson contemplates a kind of method by computer disposal text message, and is referred to as super literary
This（hypertext）, this becomes the development foundation of http hypertext transfer protocol standard architecture.
HTTP is the standard of a client and server end request and response（TCP）.Client is terminal user, service
Device end is website.By using Web browser, web crawlers or other instruments, client initiates one to server
Designated port（Default port is 80）HTTP request.We claim this client user agent（user agent）.Response
Server on store some resources, such as html file and image.Our this answering server is called source server
（origin server）.Multiple intermediate layers are there may be in the middle of user agent and source server, such as is acted on behalf of, gateway, or
Tunnel（tunnels）.Although ICP/IP protocol is most popular application on internet, http protocol does not specify to use
It and based on it support layer.In fact, HTTP can be in any other Internet protocol or real on other networks
It is existing.HTTP only assumes that its lower-layer protocols provides reliable transmission, and any agreement that can provide this guarantee can be made by it
With.
Under prior art, in HTTP data transfer, its decompression method is relatively simple, for a large amount of numbers
During according to transmission, transmission speed is there is slowly, the low problem of decompression efficiency.
The content of the invention
In order to solve problem of the prior art, the invention provides a kind of HTTP of use key frame compression
Data compression method, it can carry out classified compression, can adopt according to the difference of setting suffix name for crucial data framing
The canonical algorithm such as compress with common ZIP, data are transferred to browser end according to different situations, can be according to suffix name not
It is same to be decompressed respectively.
The technical solution adopted in the present invention is as follows：
A kind of HTTP data compression method of use key frame compression, comprises the following steps：
After A, data server receive the HTTP request of browser, check whether browser supports that HTTP compresses；
If B, support, the difference of the suffix name of the demand file according to setting, classify for crucial data framing
Compression.
In step B, compression uses common ZIP compression standard algorithms.
Step B is specifically included：
B1, described demand file are HTML or CSS static files, then data server to compression buffer directory in check whether
There is the newest compressed file of demand file；
If B2, the compressed file of demand file do not exist, data server returns to unpressed demand file to browser, and
The compressed file of demand file is deposited in buffer directory is compressed；
If B3, the newest compressed file of demand file have been present, the compressed file of demand file is directly returned；
If B4, demand file are living documents, data server dynamic compression content simultaneously returns to browser, and compressed content is not deposited
It is put into compressed cache catalogue.
The beneficial effect brought of technical scheme that the present invention is provided is：
A kind of data compression transmission method of use key frame data compression of the invention, data are transferred to according to different situations
Browser end, can respectively be decompressed according to the difference of suffix name, and it can improve decompression efficiency, so as to improve transmission
Speed.
Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, below will be to that will make needed for embodiment description
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings
Accompanying drawing.
Fig. 1 is a kind of method flow of the HTTP data compression method of use key frame compression of the invention
Figure.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Embodiment one
A kind of HTTP data compression method of use key frame compression of the present embodiment, including procedure below：
（1）After data server receives the HTTP request of browser, check whether browser supports that HTTP compresses；
（2）If browser supports HTTP compressions, data server checks the suffix name of demand file；
（3）If demand file is the static files such as HTML, CSS, checked whether in data server to compression buffer directory
Newest compressed file through there is demand file；
（4）If the compressed file of demand file does not exist, data server returns to unpressed demand file to browser, and
The compressed file of demand file is deposited in buffer directory is compressed；
（5）If the newest compressed file of demand file has been present, the compressed file of demand file is directly returned；
（6）If demand file is living document, data server dynamic compression content simultaneously returns to browser, and compressed content is not deposited
It is put into compressed cache catalogue.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
Claims (3)
1. a kind of HTTP data compression method of use key frame compression, comprises the following steps：
After A, data server receive the HTTP request of browser, check whether browser supports that HTTP compresses；
If B, support, the difference of the suffix name of the demand file according to setting, classify for crucial data framing
Compression.
2. the HTTP data compression method that a kind of use key frame according to claim 1 compresses, it is special
Levy and be, in described step B, compression uses common ZIP compression standard algorithms.
3. the HTTP data compression method that a kind of use key frame according to claim 1 and 2 compresses, its
It is characterised by, described step B is specifically included：
B1, described demand file are HTML or CSS static files, then data server to compression buffer directory in check whether
There is the newest compressed file of demand file；
If B2, the compressed file of demand file do not exist, data server returns to unpressed demand file to browser, and
The compressed file of demand file is deposited in buffer directory is compressed；
If B3, the newest compressed file of demand file have been present, the compressed file of demand file is directly returned；
If B4, demand file are living documents, data server dynamic compression content simultaneously returns to browser, and compressed content is not deposited
It is put into compressed cache catalogue.
