Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in accompanying drawing, yet should be appreciated that and can realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order more thoroughly to understand the disclosure that these embodiment are provided, and can by the scope of the present disclosure complete convey to those skilled in the art.
Fig. 1 shows the implementation of the online preview of a kind of picture of the prior art, the expanding library of its Adoption Network server and hypertext pre-service language PHP (Hypertext Preprocessor) and PHP processing graphics is that GD storehouse or the webserver and PHP and image processing software imagemagick process being uploaded to the picture of the webserver in asynchronous mode, to obtain the thumbnail of corresponding picture.As shown in Figure 1, for the picture that is uploaded to the webserver, when user wants to browse the thumbnail of this picture, browser can send the request that pulls picture thumbnail by picture thumbnail address (being generally the form of HTTP), the webserver judges whether to store the thumbnail of this picture according to this request, if no, this picture is processed to an acquiescence picture is returned to browser; If store the thumbnail of this picture in the webserver, directly the thumbnail of this picture is returned to browser.This picture thumbnail cut figure processing mode in the situation that of large concurrent high access, because the workload that service end is carried out thumbnail processing to picture is too much processed and do not come over, cause load to be risen rapidly, finally snowslide, system cannot respond.In addition, even because the thumbnail of picture is not viewed, it is also generated, and is pre-stored within the webserver, and picture processing is the application of a CPU intensity, has therefore wasted cpu resource, has also wasted storage space.
Fig. 2 and Fig. 3 show the implementation of the online preview of another kind of picture of the prior art, the expanding library of its Adoption Network server and PHP and PHP processing graphics is that GD storehouse or the webserver and PHP and image processing software imagemagick process picture in asynchronous mode, to obtain the thumbnail of corresponding picture.
For the picture that is uploaded to the webserver, when user wants to browse the thumbnail of this picture, browser can send the request that pulls picture thumbnail by picture thumbnail address, the webserver judges whether to store the thumbnail of this picture according to this request, while there is the thumbnail of this picture in the webserver, the webserver can return to the thumbnail of this picture the browser of the request of sending, as shown in Figure 2; (the not requested mistake of the thumbnail of this picture while not being cached with the thumbnail of picture in the webserver, so be not cached in the webserver), the webserver is this picture establishment thumbnail according to the request of browser, for example the message of webserver transmission establishment picture thumbnail or instruction are to cgi-server (CGI server), utilize cgi-server (it may reside in the webserver also can be independent of the webserver) to obtain the thumbnail of picture, and by this thumbnail storage in picture-storage server.If when the thumbnail of this picture of browse request this picture processed and by its thumbnail storage in picture-storage server, as shown in Figure 3, the webserver obtains the thumbnail of this picture and is cached in this locality from picture-storage server according to the request of browser, again the thumbnail of this picture is returned to browser, be shown to user.And when not obtaining picture thumbnail from picture-storage server, picture-storage server can return messages inform that picture thumbnail does not exist, and create a picture thumbnail and be stored in picture-storage server according to the request of browser side by cgi-server, when asking again, so next browser just can obtain picture thumbnail.This asynchronous processing mode is owing to having generated picture thumbnail storage before pulling picture thumbnail in the request of browser side, so same, there is the defect of waste storage space and waste cpu resource, in addition, when the size of required thumbnail or tailoring rule change, while calling, will get thumbnail, therefore also have the poor defect of real-time.
Below in conjunction with Fig. 4 and Fig. 5, the embodiment of the present invention is described in detail.
Fig. 4 shows the structural drawing of cutting in real time map device 400 according to the picture of one embodiment of the present invention.Picture is cut in real time map device 400 and is comprised the webserver 420 and distributed real-time processing module 430.
The webserver 420 be suitable for receiving requesting party transfer picture thumbnail request and sent to distributed real-time processing module 430, and according to this request, send required thumbnail to requesting party, the information that wherein said request comprises described picture and the information of required thumbnail.The information of described picture comprises the address of picture, the cryptographic hash of picture etc. can find the information of this picture; The information of required thumbnail comprises size, form (forms such as JPG, GIF) of required thumbnail etc.Here, the webserver 420 can be realized by HTTP and Reverse Proxy, for example, by Nginx, realized.Nginx (" engine x ") is a high performance HTTP and Reverse Proxy, is also an IMAP/POP3/SMTP proxy server.
The request of the thumbnail of transferring picture that distributed real-time processing module 430 transmits according to the webserver 420, processes and generates required thumbnail to picture, returns to the webserver 420.Here, distributed real-time processing module 430 for example can adopt GraphicsMagick to process picture, according to the information such as size of the required thumbnail comprising in described request, and picture described in cutting and obtain required thumbnail.Wherein GraphicsMagick is a picture processing software of increasing income.
As mentioned above, picture of the present invention is cut map device 400 in real time by using distributed real-time processing mode and the GraphicsMagick of the webserver, distributed real-time processing module 430 can realize the real-time cutting of picture being carried out to thumbnail.Concrete implementation procedure is as follows:
When the thumbnail of picture is transferred in client 410 requests, it can send request to the webserver 420, the information such as size of the information that comprises the picture that will ask in this request and the thumbnail of needs.The webserver 420 receives the request from client 410, this request can be sent to distributed real-time processing module 430.Required thumbnail is processed and generated to distributed real-time processing module 430, according to received request, to picture, returns to the webserver 420.The webserver 420 sends required thumbnail to client 410 according to the request of client 410.
Further, the webserver 420 can comprise receiving element 421, detecting unit 422, buffer unit 423 and transmitting element 424.
Wherein, receiving element 421 receives the request that requesting party transfers the thumbnail of picture, and for example, it receives the request of transferring the thumbnail of picture from client 410.
Buffer unit 423 is suitable for the required thumbnail of buffer memory picture, and the parts that can have a memory function by buffer etc. such as it are realized.Buffer unit 423 is cached the thumbnail of resulting picture, when next user asks the thumbnail of this picture, if this thumbnail meets user's requirement, can directly from buffer unit 423, transfer.Alternatively; buffer unit 423 is by required one schedule time of thumbnail buffer memory; when this thumbnail buffer memory surpasses this schedule time, this thumbnail is deleted from buffer unit 423, because if this thumbnail is not used for a long time; the utilization rate that this picture is described is not high; therefore can be deleted to avoid taking spatial cache, in addition, conventionally have a large amount of thumbnails and be buffered; in order to discharge in time spatial cache, also need regularly buffer unit 423 to be processed.
Detecting unit 422 is suitable for detecting in buffer unit 423, whether to store required thumbnail.When detecting unit 422 detects while storing required thumbnail in buffer unit 423, transmitting element 424 sends to requesting party (for example client 410) by this required thumbnail.When detecting unit 422 does not detect required thumbnail in buffer unit 423, receiving element 421 sends the request of received requesting party's the thumbnail of transferring picture to described distributed real-time processing module 430.
Distributed real-time processing module 430 can comprise task scheduling center cell 431 and picture processing server cluster unit 432.The request of the requesting party's that the task scheduling center cell 431 reception webservers 420 send the thumbnail of transferring picture, writes this request in message queue.Picture processing server cluster unit 432 comprises a plurality of picture processing server.A picture processing server in described a plurality of picture processing server pulls message from the message queue of task scheduling center cell 431, according to pulled message, required thumbnail is processed and generated to picture, then this thumbnail is returned to task scheduling center 431 with the form of message.Task scheduling center 431 returns to the webserver 420 by this thumbnail, and the webserver 420 is returned to client 410 again.Here, the picture processing server that pulls message from the message queue of task scheduling center cell 431 is idle picture processing server, when having the picture processing server of a plurality of free time to pull message from the message queue of task scheduling center cell 431, by the picture processing server first pulling, obtain message.
Fig. 5 shows the process flow diagram that a kind of picture is according to the embodiment of the present invention cut drawing method in real time.As shown in Figure 5, picture of the present invention is cut in real time drawing method 500 and is started from step 510, in step 510, receives request, the information that described request comprises this picture and the information of required thumbnail of the thumbnail of transferring picture.This step is mainly carried out by the webserver, and this webserver for example can be realized by Nginx.After picture is uploaded to the webserver, when user browses the thumbnail of this picture in browser side, the request that can send the thumbnail that pulls picture by browser is to the webserver.
Next, in step 520, according to above-mentioned request detection, whether be cached with required thumbnail.If the thumbnail of picture is requested mistake once, the webserver likely can be cached with the thumbnail of this picture, because the picture thumbnail of buffer memory is only buffered a schedule time conventionally, so, even if once generated the thumbnail of this picture, also likely because of the time, pass of a specified duration and deleted.When the webserver detects, can detect according to the requirement of the size of the thumbnail comprising in described request etc., if the size of desired thumbnail is different from the thumbnail of this picture of institute's buffer memory, the thumbnail of this picture of institute's buffer memory can not be used so, and the result of detection will be not have required thumbnail.
If detect and be cached with required thumbnail, enter step 530, send the required thumbnail of buffer memory to requesting party.As shown in Figure 6, it shows the schematic flow sheet that picture of the present invention in the situation that is cached with required thumbnail is cut an embodiment of drawing method in real time, wherein detect and be cached with required thumbnail and this buffer memory is not out of date, so the picture thumbnail of buffer memory is back to browser.
If the result detecting is the required thumbnail that there is no buffer memory, enter step 540, send described request to a picture processing server in picture processing server cluster, by this picture processing server, according to described request, this picture is processed, generate required thumbnail.Here, picture processing server cluster comprises a plurality of picture processing server, in can removing message queue when it is idle, any one picture processing server pulls message, then according to the described request in this message, picture is processed, when existing a plurality of picture processing server to go to pull message, can distribute to the picture processing server pulling at first simultaneously.Next, in step 550, send the required thumbnail being generated by picture processing server to requesting party.As shown in Figure 7, it has provided the schematic flow sheet that picture of the present invention in the situation of the required thumbnail that there is no buffer memory is cut an embodiment of drawing method in real time, wherein the webserver detects the picture thumbnail that there is no buffer memory, so send call picture cutting request to picture processing server, picture processing server is carried out cutting according to this call request to this picture and is obtained required thumbnail, and this required thumbnail is returned to the webserver, the webserver sends this required thumbnail to the browser of request.
In addition, in the situation that there is no the required thumbnail of buffer memory, the described picture processing server step that this request is sent in picture processing server cluster can comprise the steps: described request for example to write, in the message queue (can deposit in task scheduling server) of task scheduling, and a picture processor in picture processing server cluster pulls message from the message queue of described task scheduling.As shown in Figure 8, it shows according to an embodiment of the invention in the situation that do not have the required thumbnail of buffer memory to generate an example of the treatment scheme of required thumbnail.In Fig. 8, described request is written in the message queue at task scheduling center, and afterwards, a picture processing server in picture processing server cluster pulls message from the message queue of described task scheduling.Then, by this picture processing server according to pull to message in the request that comprises required thumbnail is processed and generated to this picture, afterwards generated required thumbnail is for example returned to task scheduling center with the form of message, by task scheduling center, required thumbnail is returned to called side, it is the webserver, the webserver sends requesting party again to, asks the browser of the thumbnail of picture.
In addition, before the described step that the required thumbnail being generated by picture processing server is sent to requesting party, can also comprise step: the required thumbnail that buffer memory generates.Alternatively, the required thumbnail generating can be buffered the schedule time, when this thumbnail is buffered over this schedule time, deletes this thumbnail.For example, alternatively, this schedule time can be set as this thumbnail schedule time of starting invoked time for the first time.Alternatively, this schedule time can be set as the schedule time starting from the last invoked time of this thumbnail.Method of the present invention is by above-mentioned steps, can be by generated one schedule time of thumbnail buffer memory, thereby within this schedule time, without all generate the thumbnail of this picture when picture is at every turn called.If the schedule time is set as the schedule time starting from the last invoked time of this thumbnail, when the invoked number of times of picture is frequent, the thumbnail that can make this picture this picture by the schedule time during frequently calling and afterwards in without again generating.Like this, can improve the invoked efficiency of picture, also can reduce the workload of picture processing server.In addition, if this thumbnail is not used for a long time, illustrate that the utilization rate of this picture is not high, therefore can be deleted to avoid taking spatial cache.In addition, conventionally have a large amount of thumbnails and be buffered, in order to discharge in time spatial cache, also need regularly the picture being buffered to be processed.
Utilize picture of the present invention to cut in real time map device and method thereof, because while wanting the thumbnail of browsing pictures (be user) whenever necessary just can generate thumbnail, so solved the problem that the waste storage space, waste cpu resource and the thumbnail dimensions that exist in prior art can not arbitrarily change.And whole treatment scheme is shorter, more simple in logic.In addition, prior art adopts picture-storage server cluster storage picture conventionally, and the present invention does not adopt picture-storage server cluster, but adopt picture processing server cluster that picture is processed and do not stored afterwards, directly issue the webserver and carry out buffer memory at webserver place, thereby reduced the consumption of machine, so the present invention has and makes full use of storage space, makes full use of cpu resource, generates in time thumbnail and the good feature of real-time.
