It should be noted that, it is the User Interface of cloud application that application layer can be understood as, i.e. visual and the interface that can direct control of user, and the cloud service demand that its user oriented is different, can realize the cloud of the clients such as mobile terminal, PC end, TV end and apply displaying.
Below the formation of the cloud service platform middleware of the embodiment of the present invention is explained.
Embodiment 1
Referring to Fig. 1, show the schematic diagram of the cloud service platform middleware of the embodiment of the present invention, as embodiment of the present invention middleware, form the embodiment 1 of scheme, middleware can comprise core engine layer, data Layer, supporting layer, message components layer.Below each layer explained.
(1) core engine layer, for the calling interface of different cloud services is provided, calls for the cloud application layer of middleware outside.
The most basic function of core engine layer be the calling interface that will safeguard for different cloud application services, referring to Fig. 1 examples cited, the services such as core engine layer can provide to application layer and upload, download, move, rename, search, and the calling interface of these services is provided to developer, for it.So, when developer intends building a new cloud application, as long as exploitation realizes the application layer of service display, and call when needed the corresponding interface that core engine layer provides.
It should be noted that, core engine layer is as the external interface of middleware of the present invention, can be directly and application layer communication, and according to the communicating by letter of actual service condition foundation and data Layer, supporting layer or message components layer, to this, will below explain one by one.
(2) data Layer is communicated by letter with core engine layer, for preserving user high in the clouds data.
The most basic function of data Layer is to realize high in the clouds storage, mainly by database component, is formed.
(3) supporting layer is communicated by letter with core engine layer, for the serviced component of realizing different cloud services is provided.
Application layer is called after core engine layer, by core engine layer according to application layer for the different cloud services that user provides, cooperatively interact and realize cloud service with supporting layer.Referring to Fig. 1 examples cited, supporting layer can be presented as: picture thumbnail assembly, static resource pond, video code conversion system, file distributing and accelerating system, distributed file storage system, supervisory control system etc.
The assembly that supporting layer comprises can be divided into the general purpose module of realizing different cloud services, as, the file that the dish service of cloud net and cloud album-service are uploaded all can be saved in distributed file storage system, and for these two cloud application, distributed file storage system just can be regarded as general purpose module.Or different cloud services all can be passed through supervisory control system, the health status such as application interface, message queue, server, network, disk, database principal and subordinate are monitored in real time, therefore supervisory control system also can be regarded as general purpose module.
In addition, the assembly of supporting layer also can be divided into the personalization component that realizes personalized cloud service, as, for cloud album-service, except preserving the photograph album that user uploads by distributed file storage system, when file that user uploads being detected and be picture, also can carry out picture processing by picture thumbnail assembly and generate thumbnail, and push it in static resource pond, to improve picture access speed.Again for example, for video file, it may be taken by different terminals such as mobile phone, video cameras, also may there is different video formats, after guaranteeing that user uploads successfully, can, anywhere by any this video file of equipment normal play, also tackle video file and unify transcoding.Picture thumbnail assembly, static resource pond, video code conversion system etc. all can be regarded as personalization component.

Cloud upload procedure take below as example, to utilizing the use procedure of the cloud application that middleware of the present invention builds to explain.
Embodiment 6
As above introduced, from developer's angle, it need to build an application layer that cloud upload service can be provided, and then makes this application layer communicate by letter with cloud service platform middleware of the present invention, carries out cloud upload according to following steps.Flow chart that specifically can embodiment 1 shown in Figure 2, can comprise:
Application layer is shown operation interface to user, and when receiving the file upload request that user sends by client, set up and communicate by letter with the core engine layer of middleware, call the file upload service interface that core engine layer provides to it, file upload request is submitted to this interface, trigger cloud upload procedure.
It should be noted that, what in file upload request, mainly comprise is the file fingerprint of file to be uploaded, it is the identity information of file that file fingerprint can be considered, and each file is to there being unique separately file fingerprint, and file fingerprint can pass through the formation such as file content, file size, file type.
After cloud upload service in core engine layer receives the file upload request of application layer forwarding, first according to file fingerprint, judge whether this file to be uploaded completes and upload:
If completed, upload that (no matter be that user oneself had previously uploaded this document, or other user uploaded this document, all can be considered and completed and upload.For other user, uploaded the situation of this document, active user has been equivalent to share other user's the progress of uploading and upload file), core engine layer is directly uploaded successful message by application layer to user feedback file, realizes file and passes second.
If completed, do not upload (can be embodied as file and not exist, or file is uploaded interruption), cloud upload service can be searched the uploading nodes nearest apart from this subscription client, and this uploading nodes is distributed to client, in order to realize file, uploads.
This step is to find apart from after the nearest uploading nodes of client, by application layer by the address notification client of this uploading nodes, and then by uploading nodes, file to be uploaded is uploaded to the supporting layer of middleware, specifically upload in the distributed file storage system of supporting layer.
After file has been uploaded, also need the memory address of file to be saved in data Layer, in order to subsequent user, reading or using during download file, this is also needed to carry out following two aspects and process:
First aspect, distributed file storage system is written to the memory address of file (or being interpreted as store path) in the message queue of message components layer, also can upload successful message (being mainly to be represented to user and checked by application layer) to client user's feedback file simultaneously.
Second aspect, core engine layer is safeguarding that a message reads process, this process is a regularly script, can, every a message components layer of Preset Time interval access, read the message in message queue.After distributed file storage system writes message queue by file memory address, can be read process by message and read and be saved in data Layer.So far, just completed and utilized the cloud application that middleware of the present invention builds to carry out the process that cloud is uploaded.
Embodiment 7
Referring to Fig. 3, show the flow chart of cloud method for uploading embodiment 2 of the present invention, can comprise:
Step 201, described application layer is to the calling interface Transmit message upload request of the cloud upload service in the core engine layer of described middleware, and described request comprises the file fingerprint of loopback address and file to be uploaded.
Step 202, described cloud upload service judges according to described file fingerprint whether this file to be uploaded completes and upload, if completed, does not upload, and performs step 203; If complete and upload, to user feedback, upload successfully.
Step 203, notifies the distributed file storage system in the supporting layer that described application layer is uploaded to described file to be uploaded described middleware.
Step 204, after file completes and uploads, described distributed file storage system writes the memory address of file in the message queue of message components layer of described middleware, and file is uploaded to successful information feeds back to described application layer.
Step 205, the message that described core engine layer is safeguarded reads process and accesses described message components layer by predetermined interval, therefrom read the file memory address that described distributed file storage system writes, and described file memory address is saved to the data Layer of described middleware.
Step 201～205 are basic identical with step 101～105, repeat no more herein.Difference is, also comprises and that is to say loopback address in the present embodiment in file upload request, and client user wishes, after platform confirms that file is uploaded successfully, by loopback address, to its feedback, to upload successfully acknowledge message.
Step 206, described cloud upload service sends and uploads successfully acknowledge message to described application layer.
When client, file is uploaded to result and require when comparatively strict, can in file upload request, to be added into loopback address, require platform to the state of finally uploading of its feedback file.
In cloud method for uploading embodiment 1, after file completes and uploads, distributed file storage system can be uploaded successful message to client feedback file, but, from above introducing, after distributed file storage system feeds back this message to application layer, also will read process through message reads memory address and memory address is saved in to the processing procedures such as data Layer, no matter mistake appears in which in these processes, all may cause that user is follow-up cannot correctly read or download to this upload file.Therefore, the present embodiment is also for uploading the situation that result has relatively high expectations (cloudlike backup), utilize the mode of readjustment, after guaranteeing that file memory address is correctly saved in data Layer, by core engine layer, to application layer Transmit message, upload successfully acknowledge message, with this, make client user grasp the state of finally uploading of file.
It should be noted that, carrying out the file that cloud uploads may be common document, also may be picture category file, or video class file, file for picture category and video class, in upload procedure, also need to utilize the personalization component of supporting layer to carry out special processing, explain respectively below.
After file completes and uploads, if distributed file storage system judges that this document is as picture category file, can trigger picture thumbnail assembly and generate thumbnail, and deposit described thumbnail in static resource pond.This process can be carried out before distributed file storage system writes message queue by file memory address, also can after file memory address is write to message queue, carry out, or carry out this two actions simultaneously, and this present invention can not limited.
If file to be uploaded is video file, in message, read after process reads the memory address of this document from the message queue of message components layer, core engine layer can send to file memory address video code conversion system, control video code conversion system and from distributed file storage system, read this video class file, and carry out video code conversion.In order to improve the reading speed of the video file after transcoding, video code conversion system is after completing transcoding, also the file after transcoding can be saved to file distributing and accelerating system, and the memory address in file distributing and accelerating system writes in the message queue of message components layer by it, the process that reads that waits for the arrival of news reads and is saved in data Layer.That is to say, for a video file, data Layer is preserved two memory address, and one is the memory address that is stored in the original upload file in distributed file storage system, for user, checks and downloads; One is the memory address of the file after the transcoding being stored in file distributing and accelerating system, for user, on distinct device, plays.
Above the embodiment of the present invention is described in detail, has applied embodiment herein the present invention is set forth, the explanation of above embodiment is just for helping to understand method of the present invention and platform; , for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention meanwhile.
