Below in conjunction with each accompanying drawing, the main of embodiment of the present invention technical scheme is realized principle, embodiment and set forth in detail the beneficial effect that should be able to reach.
Embodiment one
The embodiment of the present invention one proposes a kind of data object acquisition, and as shown in Figure 3, the handling process of the method comprises the following steps:
Step 31, client sends data object and obtains request.
When determining the identification information storing data object to be obtained in the buffer zone being arranged on client-side, client sends data object and obtains request, wherein obtains in request at the data object sent and comprises the identification information of client self and be arranged on the version information of the data object to be obtained stored in the buffer zone of client-side.
Client can be, but not limited to be arranged in personal computer, also can be arrange in the terminal.Client needs, when the data object that server end acquisition Capacity Ratio is larger, to need to take network transmission resource and communicate with server end, take network transmission resource and obtain data object.Such as, suppose that the far call data object that passes through that client needs to repeat obtains interface, it can be UsergetUser (intuserId) that this data object obtains interface, obtains some data objects by calling this interface at server end.Wherein, for userspersonal information, client needs the personal information obtaining user User at server end, can be, but not limited in the personal information of User be comprise the information such as user's head image information, academic information, home background, the capacity of this User data object can be tens K, also can be several million, also can determine according to the content of data object.At client-side, be provided with a buffer zone, the memory capacity of this buffer zone can be, but not limited to when arranging arrange according to the environment of client actual motion, such as, if client is arranged in personal computer, then the capacity that the ratio that the capacity of this buffer zone can configure arranges buffer zone is in the terminal larger.The configuration of buffer zone can also consider the internal memory situation of the terminal arranging client.
After being provided with buffer zone, when client obtains a certain data object, when first can determine the mark of data object to be obtained in buffer zone, then the version information of data object to be obtained is determined, and by the version information of the identification information of client self and data object to be obtained, obtain request by data object and send to server end.If when not storing the identification information of data object to be obtained in buffer zone, then client obtains this data object directly to server end.
In the technical scheme that the embodiment of the present invention one proposes here, each client is provided with unique identification.Client identification information can be, but not limited to be that terminal identification information according to arranging client is arranged, such as according to the terminal media access control (MAC arranging client, MediaAccessControl) address is arranged, or arrange according to the process that client belongs to, or according to preset algorithm using the result that obtains after MAC Address and process number the carry out computing identification information as client.Preferably, in the technical scheme that the embodiment of the present invention one proposes here, using the identification information of the MAC Address corresponding to the terminal arranging client as client.
The data object that client sends obtains the identification information comprising client self in request, such as, in the invention process one technical scheme given here, suppose that the identification information of client self is ClientID, the identification information of data object to be obtained is WIN, and the version information of data object to be obtained is WIN1.9.When then client needs to obtain data object WIN, first in the buffer zone being arranged on client-side, determine the data object tag information WIN to be obtained stored, and then determine the version information WIN1.9 that data object tag information WIN to be obtained is corresponding, send to server end the data object acquisition request that the version information comprising ClientID and data object to be obtained is WIN1.9.
Step 32, the data object that reception server end is sent obtains response message.
Wherein, comprise the version information of server end according to the identification information of client and data object to be obtained in the response message received, whether the version information judging to be arranged in client-side buffer zone the data object to be obtained stored is the judged result of latest version information.
Server end is receiving after data object that client sends obtains request, determine that data object obtains the client identification information comprised in request and the version information determining the data object that these client needs obtain, whether the version information then judging this data object to be obtained is up-to-date version information, and judged result is sent to client by the corresponding response message that obtains.
Corresponding relation between the data object version information that wherein can store client identification information and acquisition at server end.Client sends attribute information for characterizing the buffer zone being arranged on client-side, and attribute information comprises and is arranged in the buffer zone of client-side, the version information of the data object that the client of storage has obtained at server end.
Preferably, client can periodically to server end for characterizing the attribute information of the buffer zone being arranged on client-side, attribute information comprises and is arranged in the buffer zone of client-side, the version information of the data object that the client of storage has obtained at server end.After often obtaining a data object from server end, just can also send the attribute information for characterizing the buffer zone being arranged on client-side to server end.
In enforcement, when client obtains data object, suppose that this data object is user profile, comprise the information such as image Imagehead, name Stringnam, previous graduate college SchoolInfo.Its implementation can perform according to following framework:
Wherein User is the data object obtained, in the technical scheme adopting the embodiment of the present invention one to propose here, need on the basis of said frame, can obtain in the definition of data object and increase a booleanuseClientCache variable, corresponding process interface is UsergetUser (intuserId).When acquisition data object, client sends a client identification information to server end simultaneously.Further, in data object acquisition request, also need to carry a buffer zone version information cacheVersion and carry out notification server end, the version information of the data object to be obtained stored in buffer zone.When according to ClientId and cacheVersion, service end detects that same client gets a certain data object of identical version information time, server end needs the useClientCache of data object User to be set to true, and other members of data object User are set to sky.Then the information after arranging is carried at data object to obtain in response message and send to client.
Step 33, client obtains response message according to the data object that receives, judges whether to need to obtain data object corresponding to the identification information of this data object to be obtained at server end, if judged result is no, then perform step 34, otherwise, perform step 35.
In this step, be still described in detail for the acquisition framework in above-mentioned steps 32.Client is receiving after data object that server end sends obtains response message, check whether useClientCache is true, if be true, then determine to be arranged in the buffer zone of client-side, the version information of the data object to be obtained stored is latest version information, does not need the data object of the identification information elephant obtaining described data object to be obtained from server end.Otherwise, then the data object still needing the identification information elephant obtaining described data object to be obtained from server end is determined.
Step 34, response message is obtained according to described data object, when determining that the version information being arranged in client-side buffer zone the data object to be obtained stored is latest version information, client obtains data object corresponding to the identification information of described data object to be obtained from the buffer zone being arranged on client-side.
Such as, the data object received obtains in response message, if useClientCache is not true, then now determine the data object not storing this latest version information in the buffer zone of client-side, and also not do not obtain the latest edition of this data object from server end, now client obtains data object corresponding to the identification information of described data object to be obtained from server end before.
Step 35, response message is obtained according to described data object, when determining that the version information being arranged in client-side buffer zone the data object to be obtained stored is not latest version information, client obtains data object corresponding to the identification information of described data object to be obtained from server end.
Such as, the data object received obtains in response message, if useClientCache is true, client determines to be arranged on the latest edition storing data object to be obtained in the buffer zone of client-side, then now client directly obtains data object corresponding to the identification information of data object to be obtained in buffer zone.
Preferably, after above-mentioned steps 35, can also comprise:
Step 36, by data object back-up storage corresponding for the identification information that obtains described data object to be obtained from server end in the buffer zone being arranged on client-side.
For ease of obtaining the data object of this identification information next time, client also by the data object back-up storage of latest version information that obtains from server end in the buffer zone being arranged on client-side.Like this, if server end does not upgrade the version information of this data object, namely do not issue the latest edition of this data object, then subsequent client is when this data object of needs repeated obtain, can directly obtain in the buffer zone being arranged on client-side.
It should be noted that, the data object acquisition that the embodiment of the present invention one proposes here, the handling process namely shown in Fig. 3 is one preferably implementation, in force, can carry out developing and modification by the method flow according to above-described embodiment one and Fig. 3.
The technical scheme that the embodiment of the present invention one proposes here, by the process that utilizes server end powerful and storage capacity, realize data object to obtain, server end needs the history recording each client to call situation, the situation in client-cache region, so that client next time request a certain identification information data object time, judge whether to allow client use the buffer zone being arranged on client-side according to historical information, thus realize upgrading described data object at server end, issue new version information, and when cannot notify client, client still can get the data object of latest version information real-time and accurately.
