Completely it is communicated to those skilled in the art.
Fig. 1 shows a kind of realization method of the online preview of picture of the prior art, uses network server and surpasses
Expanding library, that is, GD libraries of Text Pretreatment language PHP (Hypertext Preprocessor) and PHP processing figures or net
Network server and PHP and image processing software imagemagick are in an asynchronous manner to being uploaded to the picture of network server
It is handled, to obtain the thumbnail of corresponding picture.As shown in Figure 1, the picture for being uploaded to network server, when
When user wants to browse the thumbnail of the picture, browser can be sent out through picture thumbnail address (being usually the form of HTTP)
And the request of picture thumbnail is pulled, network server judges whether to be stored with the thumbnail of the picture according to the request, if
No, then the picture is handled an acquiescence picture returning to browser；If the figure is stored in network server
The thumbnail of the picture is then directly returned to browser by the thumbnail of piece.The figure processing mode of cutting of this picture thumbnail exists
In the case of big concurrent high access, handle not come since server-side is excessive to the workload of picture progress thumbnail processing,
Load is caused rapidly to rise, final snowslide, system cannot respond to.In addition, even if the thumbnail due to picture is not browsed,
It is generated, and is pre-stored in network server, and picture processing is the application of a CPU intensive type, therefore wastes CPU
Resource wastes memory space.
Fig. 2 and Fig. 3 show the realization methods of the online preview of another picture of the prior art, use network service
Expanding library, that is, GD the libraries or network server of device and PHP and PHP processing figure and PHP and image processing software
Imagemagick is in an asynchronous manner handled picture, to obtain the thumbnail of corresponding picture.
For being uploaded to the picture of network server, when user wants to browse the thumbnail of the picture, browser can be sent out
Go out the request that picture thumbnail is pulled by picture thumbnail address, network server judges whether to be stored with according to the request
The thumbnail of the picture, when the thumbnail that the picture is had existed in network server, network server can be by the picture
Thumbnail returns to the browser for sending out request, as shown in Figure 2；When the thumbnail that picture is not cached in network server
(i.e. the thumbnail of the picture was not requested, so being not cached in network server), network server is according to browser
It asks to create thumbnail for the picture, such as network server sends the message for creating picture thumbnail or instructs to cgi-
Server (CGI servers), using cgi-server, (it can reside in network server can also be independently of network service
Device) thumbnail of picture is obtained, and by the thumbnail storage in picture storage server.If in the browse request picture
Thumbnail when the picture it is processed and by its thumbnail storage if picture storage server, as shown in figure 3, network
Server obtains the thumbnail of the picture according to the request of browser from picture storage server and is cached in local, then should
The thumbnail of picture returns to browser, is shown to user.And when picture thumbnail has not been obtained from picture storage server, figure
Piece storage server can return to message and inform that picture thumbnail is not present, and be created by cgi-server according to the request of browser side
It builds a picture thumbnail and is stored in picture storage server, browser next in this way is obtained with figure when asking again
Piece thumbnail.This asynchronous processing mode before the request of browser side pulls picture thumbnail due to having generated picture
Thumbnail simultaneously stores, so the defects of equally existing waste memory space and waste cpu resource, in addition, when required thumbnail
Size or tailoring rule when changing, when calling will can not get thumbnail, therefore also lack there are real-time is poor
It falls into.
The embodiment of the present invention is described in detail with reference to Fig. 4 and Fig. 5.
Fig. 4 shows that a kind of picture of embodiment according to the present invention cuts the structure chart of map device 400 in real time.Picture is real

Further, network server 420 can include receiving unit 421, detection unit 422,423 and of buffer unit
Transmitting element 424.
Wherein, receiving unit 421 receives the request that requesting party transfers the thumbnail of picture, for example, it is received from client
Transfer the request of the thumbnail of picture in end 410.
Buffer unit 423 is suitable for the required thumbnail of caching picture, such as it can have store function by buffer etc.
Component realize.The thumbnail of obtained picture is cached by buffer unit 423, and next user asks the contracting of the picture
During sketch map, if the thumbnail meets the requirement of user, can directly it be transferred from buffer unit 423.Optionally, caching is single
Required thumbnail is cached a predetermined time by member 423, and when thumbnail caching is more than the predetermined time, then the thumbnail is postponed
It is deleted in memory cell 423, because if the thumbnail is not used for a long time, then illustrates that the utilization rate of this picture is not high, therefore
It can be deleted to occupy spatial cache, be buffered in addition, usually having a large amount of thumbnail, in order to discharge in time
Spatial cache, it is also desirable to periodically handle buffer unit 423.
Detection unit 422 is adapted to detect for whether being stored with required thumbnail in buffer unit 423.When detection unit 422 is examined
When measuring thumbnail needed for being stored in buffer unit 423, which is sent to requesting party's (example by transmitting element 424

The form of message returns to task scheduling center 431.The thumbnail is returned to network server 420 by task scheduling center 431,
Network server 420 is returned to client 410 again.Here, it is pulled from the message queue of task scheduling center cell 431
The picture processing server of message is idle picture processing server, when the picture processing server for having multiple free time is from task
When pulling message in the message queue of control centre's unit 431, message is obtained by the picture processing server first pulled.
A kind of picture that Fig. 5 shows according to the embodiment of the present invention cuts the flow chart of drawing method in real time.Such as Fig. 5 institutes
Show, picture of the invention cuts drawing method 500 and starts from step 510 in real time, and in step 510, asking for the thumbnail of picture is transferred in reception
It asks, the information of the information of the request comprising the picture and required thumbnail.The step is mainly performed by network server,
The network server can for example be realized by Nginx.After picture is uploaded to network server, user is in browser side
When browsing the thumbnail of the picture, the request for the thumbnail for pulling picture can be sent by browser to network server.
Next, in step 520, whether required thumbnail is cached with according to above-mentioned request detection.If the breviary of picture
Figure was once requested, then network server is it is possible that the thumbnail of the picture can be cached with, due to the picture thumbnail of caching
A predetermined time is usually only buffered, so, even if once generating the thumbnail of the picture, it is also possible to because the time is too long
And it is deleted.When network server is detected, can according to included in the request size of thumbnail etc. requirement into
Row detection, if the size of required thumbnail is different from the thumbnail of the picture cached, then the figure cached
The thumbnail of piece can not be used, and the result of detection will be that required thumbnail is not present.
If detection is cached with required thumbnail, 530 are entered step, sends the required thumbnail of caching to request
Side.As shown in fig. 6, picture of the invention in the case of it illustrates thumbnail needed for being cached with cuts a reality of drawing method in real time
The flow diagram of example is applied, wherein detection is cached with required thumbnail and the caching is not out of date, then by the picture breviary of caching
Figure is back to browser.
If detection the result is that the required thumbnail not cached, enters step 540, send the request to figure
A picture processing server in piece processing server cluster, by the picture processing server according to the request to the picture
It is handled, thumbnail needed for generation.Here, picture processing server cluster includes multiple picture processing servers, when any
One picture processing server can go to pull message in message queue in its free time, then according in the message
Request handles picture, when going to pull message simultaneously there are multiple picture processing servers, can distribute to and pull at first
Picture processing server.Next, in step 550, it please by being sent to by the required thumbnail that picture processing server generates
The side of asking.As shown in fig. 7, picture of the invention in the case of which show the required thumbnail of no caching cuts drawing method in real time
The flow diagram of one embodiment, wherein network server detect the picture thumbnail not cached, and then send out calling
The request that picture is cut to picture processing server, picture processing server the picture is cut according to the call request and
Required thumbnail is obtained, and the required thumbnail is returned into network server, network server transmits the required thumbnail
To the browser of request.
In addition, in the case of the required thumbnail of no caching, it is described to communicate the request to picture processing server
A picture processing server step in cluster may include steps of：The request is written to the message team of task scheduling
It arranges in (such as task scheduling server can be deposited in), a picture processor in picture processing server cluster is from described
Message is pulled in the message queue of task scheduling.As shown in figure 8, it is not being cached it illustrates according to an embodiment of the invention
Required thumbnail in the case of generation needed for thumbnail process flow an example.In fig. 8, the request is written into
In the message queue of task control centre, later, a picture processing server in picture processing server cluster is from institute
It states in the message queue of task scheduling and pulls message.Then, it is wrapped by the picture processing server according in the message pulled
The request contained handles the picture and generates required thumbnail, later by the required thumbnail generated for example with message
Form returns to task scheduling center, and required thumbnail is returned to called side, i.e. network server, net by task scheduling center
Network server sends requesting party to again, that is, asks the browser of the thumbnail of picture.
In addition, before described the step of sending the required thumbnail generated by picture processing server to requesting party also
It can include step：Cache the required thumbnail generated.Optionally, the required thumbnail generated can be buffered pre- timing
Between, when the thumbnail was buffered more than the predetermined time, delete the thumbnail.For example, optionally, which can set
It is set to the predetermined time that the thumbnail time called for the first time starts.Optionally, the predetermined time can be set as from
The predetermined time that the thumbnail last time called time starts.The method of the present invention can be incited somebody to action by above-mentioned steps
The thumbnail generated caches a predetermined time, thus within the predetermined time, without all being generated when picture is called every time
The thumbnail of the picture.If the predetermined time is set as the pre- timing since the thumbnail last time called time
Between, then when the number that picture is called is frequent, can make the thumbnail of the picture during the picture is called frequently and it
Without generating again in predetermined time afterwards.In this way, the efficiency that picture is called can be improved, picture processing clothes can also be reduced
The workload of business device.If in addition, the thumbnail is not used for a long time, illustrate that the utilization rate of this picture is not high, therefore can
Spatial cache is occupied to be deleted.It is buffered in addition, usually having a large amount of thumbnail, it is slow in order to discharge in time
Deposit space, it is also desirable to periodically buffered picture be handled.
Map device and its method are cut in real time using the picture of the present invention, since (i.e. user wants browsing pictures whenever necessary
Thumbnail when) can just generate thumbnail, so solve it is in the prior art waste memory space, waste cpu resource,
The problem of can not arbitrarily changing with thumbnail dimensions.Moreover, entire process flow is shorter, it is more simple in logic.It is in addition, existing
Technology generally use picture storage server cluster-based storage picture, and the present invention does not use picture storage server cluster, but
After being handled using picture processing server cluster picture and without storage, network server is directly issued and in net
It is cached at network server, so as to reduce the consumption of machine, therefore the present invention has and makes full use of memory space, fully profit
