At length set forth to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
Embodiment one
The embodiment of the invention one proposes a kind of data object acquisition methods, and as shown in Figure 3, the handling process of this method may further comprise the steps:
Step 31, the user end to server end sends data object and obtains request.
When storage remains to obtain the identification information of data object in determining the buffer zone that is arranged on client-side, the user end to server end sends data object and obtains request, wherein obtains the identification information that comprises client self in the request and is arranged on the version information of storing in the buffer zone of client-side of waiting to obtain data object at the data object that sends.
Client can but be not limited to be arranged in the personal computer, also can be arranged in the portable terminal.Client need be when server end obtains the bigger data object of Capacity Ratio, need take network transmission resource and server end communicates, and takies network transmission resource and obtains data object.For example, suppose that the far call data object that passes through that client need repeat obtains interface, it can be User getUser (int user Id) that this data object obtains interface, obtains some data objects by calling this interface at server end.Wherein, be example with userspersonal information, client need be obtained the personal information of user User at server end, in the personal information of User can but to be not limited to be to comprise 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 when arranging can but be not limited to arrange according to the environment of client actual motion, for example, if client is arranged in the personal computer, then to be arranged on the capacity of the buffer zone in the portable terminal big for the capacity of this buffer zone ratio that can dispose.The configuration of buffer zone can also be taken all factors into consideration the internal memory situation of the terminal that client is set.
After being provided with the buffer zone, when client is obtained a certain data object, in the time of can in the buffer zone, determining to wait to obtain the sign of data object earlier, determine to wait to obtain the version information of data object then, and with the identification information of client self with wait to obtain the version information of data object, send to server end by the data object request of obtaining.If when not having storage to wait to obtain the identification information of data object in the buffer zone, then client is directly obtained this data object to server end.
In the technical scheme that the embodiment of the invention one proposes here, each client is provided with unique identification.Client identification information can but to be not limited to be that terminal identification information according to client is set arranges, for example according to the terminal media access control (MAC that client is set, Media Access Control) address arranges, or arrange according to the process that client belongs to, or according to preset algorithm MAC Address and process number are carried out the result that obtains after the computing as the identification information of client.Preferably, in the technical scheme that the embodiment of the invention one proposes here, with the identification information of the corresponding MAC Address of the terminal that client is set as client.
The data object that the user end to server end sends obtains the identification information that comprises client self in the request, for example in the invention process one technical scheme given here, the identification information of supposing client self is Client ID, 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 need be obtained data object WIN, at first in being arranged on the buffer zone of client-side, determine the data object tag information WIN to be obtained of storage, and then determine the version information WIN1.9 of data object tag information WIN correspondence to be obtained, sending the version information that comprises Client ID and wait to obtain data object to server end is that the data object of WIN1.9 obtains request.
Step 32, the data object that the reception server end is sent obtains response message.
Wherein, comprise server end in the response message that receives according to the identification information of client and wait to obtain the version information of data object, judge that being arranged on waiting of storing in the client-side buffer zone obtains whether the version information of data object is the judged result of latest version information.
Server end is receiving after data object that client sends obtains request, the client identification information that comprises in the request of specified data object acquisition and the version information of determining the data object that this client need be obtained, judge then whether this version information of waiting to obtain data object is up-to-date version information, and judged result is obtained response message by correspondence send to client.
Wherein server end can store client identification information and the data object version information obtained between corresponding relation.The user end to server end send to be used for characterizes the attribute information of the buffer zone that is arranged on client-side, and attribute information comprises in the buffer zone that is arranged on client-side, the version information of the data object that the client of storage has obtained at server end.
Preferably, client can periodically be used for characterizing the attribute information of the buffer zone that is arranged on client-side to server end, attribute information comprises in the buffer zone that is arranged on client-side, the version information of the data object that the client of storage has obtained at server end.Can also whenever obtained data object from server end after, just send the attribute information that is used for characterizing the buffer zone that is arranged on client-side to server end.
In the enforcement, when client is obtained data object, suppose that this data object is user profile, comprise image I mage head, information such as name String nam, previous graduate college SchoolInfo.Its implementation can be carried out according to following framework:
Wherein User is the data object that obtains, in the technical scheme that the employing embodiment of the invention one proposes here, need be on the basis of said frame, can obtain increases a boolean use Client Cache variable in the definition of data object, corresponding process interface is User getUser (int userId).When obtaining data object, client sends a client identification information to server end simultaneously.And obtaining at data object also needs to carry a buffer zone version information cacheVersion and comes the notification server end, the version information of storing in the buffer zone of waiting to obtain data object in the request.When service end detects same client and brings in a certain data object of getting identical version information according to ClientId and cacheVersion, server end need data object User useClientCache be set to true, other members of data object User are set to empty getting final product.Information after will arranging then is carried at data object and obtains and send to client in the response message.
Step 33, client is obtained response message according to the data object that receives, and judges whether and need obtain the identification information corresponding data objects that this waits to obtain data object at server end, if judged result is for denying, then execution in step 34, otherwise, execution in step 35.
In this step, be that example is described in detail with the framework that obtains in the above-mentioned steps 32 still.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, storage wait that the version information that obtains data object is latest version information, do not need to obtain the described data object of waiting to obtain the identification information elephant of data object from server end.Otherwise, still need then to determine to obtain the described data object of waiting to obtain the identification information elephant of data object from server end.
Step 34, obtain response message according to described data object, determining when being arranged on waiting of storing in the client-side buffer zone and obtaining the version information of data object and be latest version information, client is obtained the described identification information corresponding data objects of waiting to obtain data object from the buffer zone that is arranged on client-side.
For example, the data object that receives obtains in the response message, if useClientCache is not true, then do not store the data object of this latest version information in the buffer zone of at this moment definite client-side, and also do not obtain the latest edition of this data object from server end, this moment, client was obtained the described identification information corresponding data objects of waiting to obtain data object from server end before.
Step 35, obtain response message according to described data object, determining when being arranged on waiting of storing in the client-side buffer zone and obtaining the version information of data object and be not latest version information, client is obtained the described identification information corresponding data objects of waiting to obtain data object from server end.
For example, the data object that receives obtains in the response message, if useClientCache is true, client is determined to be arranged in the buffer zone of client-side and has been stored the latest edition of waiting to obtain data object, and then this moment, client was directly obtained the identification information corresponding data objects of waiting to obtain data object in the buffer zone.
Preferably, after above-mentioned steps 35, can also comprise:
Step 36 will be obtained from server end and describedly wait to obtain the identification information corresponding data objects back-up storage of data object to the buffer zone that is arranged on client-side.
For ease of obtaining the data object of this identification information next time, the data object back-up storage of the latest version information that client also will be obtained from server end is to the buffer zone that is 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 can directly obtain in being arranged on the buffer zone of client-side when needs repeat to obtain this data object.
Need to prove, the data object acquisition methods that the embodiment of the invention one proposes here, handling process namely shown in Figure 3 is a kind of preferable implementation, in force, can develop and modification according to above-described embodiment one and method flow shown in Figure 3.
The technical scheme that the embodiment of the invention one proposes here, by utilizing the powerful processing of server end and storage capacity, realize that data object obtains, server end need record the history of each client and call situation, the situation in client-cache zone, so that during the data object of a certain identification information of client request next time, judge whether to allow client use the buffer zone that is arranged on client-side according to historical information, thereby being implemented in server end upgrades described data object, issue new version information, and when can't notify client, client still can get access to the data object of latest version information real-time and accurately.
Correspondingly, the embodiment of the invention one proposes a kind of data object deriving means, and this device is positioned at client-side, and as shown in Figure 4, this device comprises:

Embodiment two
The embodiment of the invention two proposes a kind of data object acquisition methods here, and as shown in Figure 5, its handling process is as follows:
Server end receives client in determining the buffer zone that is arranged on client-side, and when storage remained to obtain the identification information of data object, the data object of sending obtained request.The request of obtaining of wherein said data object comprises the identification information of client self and is arranged on the version information of storing in the buffer zone of client-side of waiting to obtain data object.
In the technical scheme that the embodiment of the invention two proposes here, server end possesses stronger disposal ability and storage capacity.Client can but be not limited to be arranged in the personal computer, also can be arranged in the portable terminal.Client need be when server end obtains the bigger data object of Capacity Ratio, need take network transmission resource and server end communicates, and takies network transmission resource and obtains data object.For example, suppose that the far call data object that passes through that client need repeat obtains interface, it can be User getUser (int user Id) that this data object obtains interface, obtains some data objects by calling this interface at server end.Wherein, be example with userspersonal information, client need be obtained the personal information of user User at server end, in the personal information of User can but to be not limited to be to comprise information such as user's head image information, academic information, home background, the capacity of this data object User can be tens K, also can be several million, can determine according to the content of data object.At client-side, be provided with a buffer zone, during the arranging of the memory capacity of this buffer zone can but be not limited to arrange according to the environment of client actual motion, if for example client is arranged in the personal computer, then to be arranged on the capacity of the buffer zone in the portable terminal big for the capacity of this buffer zone ratio that can dispose.The configuration of buffer zone can also be taken all factors into consideration the internal memory situation of the terminal that client is set.
And at server end, can store more data object, and server end can upgrade the data object of self storage, the data object of real-time release latest version information, and for example the data object of a certain version information to storage carries out edition upgrading etc.
After client-side is provided with the buffer zone, client need be when server end obtains the data object of a certain identification information, in determining the buffer zone that is arranged on client-side, when storage remains to obtain the identification information of data object, send data object and obtain request.Server end can obtain request according to data object, knows the identification information of client and is arranged on the version information of storing in the buffer zone of client-side of waiting to obtain data object.In the technical scheme that the embodiment of the invention proposes here, each client is provided with unique identification.Client identification information can but to be not limited to be that terminal identification information according to client is set arranges, for example according to the terminal media access control (MAC that client is set, Media Access Control) address arranges, or arranges according to the process that client belongs to.Preferably, in the technical scheme that the embodiment of the invention proposes, say that the corresponding MAC Address of the terminal that client is set is as the identification information of client.
The data object that the user end to server end sends obtains the identification information that comprises client self in the request, and in the technical scheme that the embodiment of the invention proposes, each client is provided with unique identification.Client identification information can but to be not limited to be that terminal identification information according to client is set arranges, for example according to the terminal media access control (MAC that client is set, Media Access Control) address arranges, or arranges according to the process that client belongs to.Preferably, in the technical scheme that the embodiment of the invention proposes here, with the identification information of the corresponding MAC Address of the terminal that client is set as client.For example in two li technical schemes that provide of the invention process, the identification information of supposing client self is Client ID, and the identification information of data object to be obtained is WIN.When then client need be obtained identification information and is the data object of WIN, at first in being arranged on the buffer zone of client-side, search, determine whether comprise the data object that identification information is WIN in the buffer zone, in the technical scheme that the embodiment of the invention two proposes here, suppose to comprise in the buffer zone data object that identification information is WIN, after finding the data object that identification information is WIN, determine that the identification information that comprises in the buffer zone is the version information of the data object of WIN, be assumed to be WIN1.9, then the data object that receives of server end obtains the version information WIN1.9 that waits to obtain data object WIN that stores in the identification information Client ID that includes client in the request and the buffer zone.
Wherein, judge and to be arranged on waiting of storing in the client-side buffer zone whether obtain the version information of data object be that the processing procedure of latest version information is as follows:
Step 1: in the client identification information of storage in advance and obtain in the corresponding relation between the version information of data object, determine that the identification information clients corresponding of the described client that receives obtained the version information of whole data objects at server end.
Wherein, client identification information and obtain corresponding relation between the version information of data object, can but be not limited to determine in the following manner:
First kind of mode: server end receives the attribute information that is used for characterizing the buffer zone that is arranged on client-side that client sends, wherein said attribute information comprises in the buffer zone that is arranged on client-side, the version information of the data object that the client of storage has obtained at server end; Corresponding relation between the version identifier of the data object of storing in the buffer zone that is arranged on client-side that foundation receives and the identification information of described client.
In this kind mode, preferably, server end can periodically receive the attribute information that is used for characterizing the buffer zone that is arranged on client-side that client is sent.Also can be the transfer resource free time, receive the attribute information that is used for characterizing the buffer zone that is arranged on client-side that client is sent.
The second way: server end is set up the corresponding relation between the identification information of the version information of the data object send to client and described client after sending to client and waiting to obtain the identification information corresponding data objects of data object.
In this kind mode, server end is not after sending to client and waiting to obtain the identification information corresponding data objects of data object, self just sets up a kind of corresponding relation, client need not regularly send the attribute information that characterizes the buffer zone that is arranged on client-side to server end like this, and then saves transfer resource preferably.
Step 2: the version information that waiting of will receiving obtained the data object of the version information of data object and server end storage compares.
Step 3: if it is identical with the version information of the data object of server end storage to wait to obtain the version information of data object, then determining to be arranged on waiting of storing in the client-side buffer zone, to obtain the version information of data object be latest version information, if it is inequality, execution in step four, if instead identical, execution in step five.
Step 4: if it is inequality to wait to obtain the version information of data object of the version information of data object and server end storage, then determining to be arranged on waiting of storing in the client-side buffer zone, to obtain the version information of data object be not latest version information.
In the enforcement, when client is obtained data object, suppose that this data object is user profile, comprise image I mage head, information such as name String nam, previous graduate college SchoolInfo.Its implementation can be carried out according to following framework:
Wherein User is the data object that obtains, in the technical scheme that the employing embodiment of the invention one proposes here, need be on the basis of said frame, can obtain increases a boolean use Client Cache variable in the definition of data object, corresponding process interface is User getUser (int userId).When obtaining data object, client sends a client identification information to server end simultaneously.And obtaining at data object also needs to carry a buffer zone version information cacheVersion and comes the notification server end, the version information of storing in the buffer zone of waiting to obtain data object in the request.
When service end detects same client and brings in a certain data object of getting identical version information according to ClientId and cacheVersion, server end need data object User useClientCache be set to true, other members of data object User are set to empty getting final product.Information after will arranging then is carried at data object and obtains and send to client in the response message.
Correspondingly, the embodiment of the invention two also proposes a kind of data object deriving means here, and it is distolateral that this device is positioned at server, and as shown in Figure 6, this device comprises:
Wherein, this judge module 602 also comprises:
Preferably, above-mentioned correspondence relation storage 6021, also be used for determining in the following manner the corresponding relation between client identification information and the version information that obtains data object: after sending to client and waiting to obtain the identification information corresponding data objects of data object, foundation sends to the corresponding relation between the identification information of the version information of data object of client and described client.

Wherein, judge that be arranged on waiting of storing in the client-side buffer zone obtains whether the version information of data object is the processing procedure of latest version information, see also in the above-mentioned enforcement two, the elaborating of step 52, the embodiment of the invention three repeats no more here.
Step 74, server end is carried at data object with judged result and obtains in the response message, sends to client.
In the enforcement, can obtain increases a boolean use Client Cache variable in the definition of data object, and corresponding process interface is User getUser (int userId).When obtaining data object, client sends a client identification information to server end simultaneously.And obtaining at data object also needs to carry a buffer zone version information cacheVersion and comes the notification server end, the version information of storing in the buffer zone of waiting to obtain data object in the request.
When service end detects same client and brings in a certain data object of getting identical version information according to ClientId and cacheVersion, server end need data object User useClientCache be set to true, other members of data object User are set to empty getting final product.Information after will arranging then is carried at data object and obtains and send to client in the response message.
Step 75, the data object that client reception server end is sent obtains response message.
Wherein, comprise server end in the response message that receives according to the identification information of client and wait to obtain the version information of data object, judge that being arranged on waiting of storing in the client-side buffer zone obtains whether the version information of data object is the judged result of latest version information.
Step 76, client is obtained response message according to the data object that receives, and judges whether and need obtain the identification information corresponding data objects that this waits to obtain data object at server end, if judged result is for being, then execution in step 77, otherwise, execution in step 78.
In this step, be that example is described in detail with the framework that obtains in the above-mentioned steps 75 still.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, storage wait that the version information that obtains data object is latest version information, do not need to obtain the described data object of waiting to obtain the identification information elephant of data object from server end.Otherwise, still need then to determine to obtain the described data object of waiting to obtain the identification information elephant of data object from server end.
Step 77, obtain response message according to described data object, determining when being arranged on waiting of storing in the client-side buffer zone and obtaining the version information of data object and be not latest version information, client is obtained the described identification information corresponding data objects of waiting to obtain data object from server end.
For example, the data object that receives obtains in the response message, if useClientCache is not true, then do not store the data object of this latest version information in the buffer zone of at this moment definite client-side, and also do not obtain the latest edition of this data object from server end, this moment, client was obtained the described identification information corresponding data objects of waiting to obtain data object from server end before.
