Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is described.
In order to provide a user better service, Internet company needs by gathering substantial amounts of user data to understand use The use habit and preference at family.Since the data volume of user data is larger, compression dictionary can be used by client to number of users According to being uploaded to server end again after being compressed.In practical applications, user data is usually with key assignments (key：Value) to shape Formula stores, in addition, compression dictionary includes the correspondence of value value and sequence number.
Since the resource data amount of client is big and is constantly updating, in order to ensure compression efficiency, it is necessary in client and Server end increases new compression dictionary in time.At present, can visitor be made by the software version of updating client and server end Family end and server end get new compression dictionary.But upgrade in time software version due to being unable to control client, it may It is present with that the software version of server end is promoted, but the situation that the software version of client not yet upgrades.At this point, server End has got new compression dictionary, and new compression dictionary has not been obtained in client, in such a scenario, server end and visitor The detailed process of transmission data between the end of family is：
First, client is judged in the existing compression dictionary of client, if there are user data correspondences to be uploaded Compression dictionary, specifically, bag can be determined whether there is in existing compression dictionary according to the value in user data Include the compression dictionary of the value；If it is, being compressed processing to user data using the compression dictionary, generation is compressed User data；If it has not, upload unpressed user data to server end.
Next, the user data that received server-side client is sent, judges whether the user's data have been compressed；If It is that decompression processing, the user data after being decompressed are carried out to the user's data using the user's data corresponding compression dictionary； If it has not, directly acquire unpressed user data.
As it can be seen that when client lacks compression dictionary, processing can not be compressed to the user data of part, still, to Server end uploads unpressed user data, can occupy substantial amounts of floating resources and bandwidth resources.
To solve the above-mentioned problems, an embodiment of the present invention provides it is a kind of obtain compression dictionary method and apparatus, first, Client sends datagram, and data message includes unpressed user data and for asking unpressed use The request mark of the corresponding targeted compression dictionary of user data；Then, server end receive client send data message it Afterwards, judge the request mark for asking the corresponding targeted compression dictionary of unpressed user data whether is carried in data message Know, if it is, establish targeted compression dictionary and sent to client；Finally, client obtains the target from server end Compress dictionary.In this way, client can be by sending the targeted compression dictionary needed for unpressed user data to server end Request mark, obtain compression dictionary.Even if the software version of client does not update, can also be got from server end required Compression dictionary, avoid occupying substantial amounts of floating resources and bandwidth provides due to sending unpressed user data to server end The service efficiency of floating resources and bandwidth resources is improved in source.
An embodiment of the present invention provides a kind of method for obtaining compression dictionary, applied to client.Referring to Fig. 1, Fig. 1 is this A kind of flow chart of the method for the acquisition compression dictionary of inventive embodiments, includes the following steps：
Step 101, send datagram to server end.
Wherein, data message includes unpressed user data target corresponding with for asking unpressed user data Compress the request mark of dictionary.
In this step, client can send datagram to server end, which includes unpressed use User data and for ask the request of the corresponding targeted compression dictionary of unpressed user data identify, with realize by should Request mark, request server end establishes the targeted compression dictionary and is sent to client.
Optionally, before step 101, the method provided in an embodiment of the present invention for obtaining compression dictionary can also include：
Judge in the existing compression dictionary of client, if there are the corresponding targeted compression words of unpressed user data Allusion quotation；
If it has not, it adds to ask asking for the corresponding targeted compression dictionary of unpressed user data in data message Seek mark.
Specifically, whether client before sending datagram to server end, can determine client first Preserve to compress the targeted compression dictionary of the user's data；If so, it is sent out after the user's data are compressed with processing It send to server end, in this case, data message includes compressed data；If not provided, it can add in data message Add to ask the request of the corresponding targeted compression dictionary of the user's data to identify, in this case, data message includes Unpressed user data and the request identify.
Optionally, add to ask the corresponding targeted compression word of unpressed user data in data message above-mentioned Before the step of request mark of allusion quotation, the method provided in an embodiment of the present invention for obtaining compression dictionary can also include：
Determine the correspondence of the target key and default identifier in unpressed user data；
The correspondence of target key and the identifier are determined as request mark.
It should be noted that the storage format of unpressed user data can be key：value.Specifically, client Target key in unpressed user data and the correspondence of default identifier can be determined as request mark.
For example, unpressed user data can be：Key0=value0＆key1=value1, wherein, target key bags Key0 and key1 are included, corresponding value is respectively value0 and value1；Default identifier can be suggesting；That , the correspondence of target key and suggesting can be determined as to request mark, are specifically denoted as suggesting= Key0, key1.In this case, the data message that client is sent can be key0=value0＆key1 =value1＆suggesting=key0, key1.
In specific implementation process, client can be these users with the higher user data of selected section compression efficiency Request of data targeted compression dictionary.Optionally, add to ask unpressed user data pair in data message above-mentioned Before the step of request mark for the targeted compression dictionary answered, the method provided in an embodiment of the present invention for obtaining compression dictionary, also It can include：
Judge the word of number that unpressed user data occurs in preset time period and unpressed user data Whether length is no meets preset condition for section；
It adds to ask the corresponding targeted compression word of unpressed user data in data message if it has, then performing The step of request mark of allusion quotation.
Specifically, can preset condition be set according to actual conditions, wherein, preset condition can be included in preset time period The number that interior unpressed user data occurs is more than the byte length of default frequency threshold value and unpressed user data More than default length threshold etc..When unpressed user data meets preset condition, it is believed that these user data categories In the higher user data of compression efficiency, can just be added in data message for the request mark of request target compression dictionary. So, it is possible to reduce client and the workload of server end improve work efficiency.
Further, the step of whether unpressed user data meets preset condition judged, including：
Judge the number, the byte with unpressed user data that unpressed user data occurs in preset time period Whether the product of length is more than predetermined threshold value；
It is described to be used to ask the corresponding mesh of unpressed user data described in addition in data message if it has, then performing The step of request mark of mark compression dictionary, including：
If the number that unpressed user data occurs in preset time period, the byte long with unpressed user data The product of degree is more than predetermined threshold value, then unpressed user data meets preset condition, performs to add in data message and is used for The step of request of the corresponding targeted compression dictionary of unpressed user data is asked to identify.
Specifically, preset condition can be arranged to number that unpressed user data occurs in preset time period, Whether the product with the byte length of unpressed user data is more than predetermined threshold value, if the product is more than predetermined threshold value, explanation The user's data fit preset condition belongs to the higher user data of compression efficiency, can add to ask in data message The request of targeted compression dictionary is asked to identify；If the product is not above predetermined threshold value, illustrate that the user's data do not meet default item Part is not belonging to the higher user data of compression efficiency, without addition the asking for request target compression dictionary in data message Seek mark.
It is of course also possible to preset condition is set according to actual demand, so that client can be according to the characteristics of user itself To ask most suitable dictionary.
Step 102, the targeted compression dictionary that server end is sent is obtained, to use targeted compression dictionary to unpressed use User data is compressed processing.
Wherein, the targeted compression dictionary is that the server receives the data message that client is sent, and judges the number It is identified according to the request whether is carried in message, if it is, establish the targeted compression dictionary and sent to the client.
In this step, client can obtain the targeted compression dictionary of server end transmission, in this way, client just can Using the targeted compression dictionary, processing is compressed to unpressed user data；Wherein, server end is being received from visitor During the data message at family end, it can first judge above-mentioned request mark whether is carried in the data message, if so, the data message In user data for uncompressed data, server end can establish targeted compression dictionary for the user's data, and to client End sends the targeted compression dictionary, so that client obtains the targeted compression dictionary.
Optionally, step 102 can include：
Receive the target key in the unpressed user data that server end is sent and the target sequence in targeted compression dictionary The correspondence of row number, target sequence number are target value corresponding default sequence number, target in targeted compression dictionary Value is target key corresponding value in unpressed user data；
According to the correspondence and unpressed user data of target key and target sequence number, targeted compression word is generated Allusion quotation.
Specifically, since the value values in user data are generally included compared with multibyte, server end is directly sent out to client Send compression dictionary that may occupy more floating resources and bandwidth resources.In order to improve transmitting efficiency, server end can be to Client sends the correspondence of target key and target sequence number, makes client according to the correspondence and unpressed use User data obtains targeted compression dictionary；Wherein, target sequence number is corresponding default in targeted compression dictionary for target value Sequence number, target value be target key corresponding value in unpressed user data.
For example, unpressed user data can be：Key0=value0＆key1=value1, the target key received Include the correspondence of key0 and $ K0 and the correspondence of key1 and $ K1 with the correspondence of target sequence number；So, it is objective Family end is according to the correspondence and key1 that receive key0 and $ K0 and the correspondence of $ K1, with reference to unpressed number of users According to key0=value0＆key1=value1, it can learn that targeted compression dictionary includes the correspondence of value0 and $ K0, with And the correspondence of value1 and $ K1.
As it can be seen that in the method provided in an embodiment of the present invention for obtaining compression dictionary, client is sent out first to server end Data message is sent, data message includes unpressed user data target pressure corresponding with for asking unpressed user data The request mark of contracting dictionary；Then, client obtains the targeted compression dictionary that server end is sent, and targeted compression dictionary is service Device judges whether carry to ask unpressed number of users in data message after the data message that client is sent is received It is identified according to the request of corresponding targeted compression dictionary, if it is, establish targeted compression dictionary and sent to client.In this way, Client can be identified by sending the request of the targeted compression dictionary needed for unpressed user data to server end, be obtained Compress dictionary.Even if the software version of client does not update, required compression dictionary can be also got from server end, is avoided Substantial amounts of floating resources and bandwidth resources are occupied due to sending unpressed user data to server end, improve floating resources With the service efficiency of bandwidth resources.
In addition, in embodiments of the present invention, it can determine to obtain the higher user data institute of compression efficiency by client The compression dictionary needed, and server end only needs to establish corresponding compression dictionary according to the request of client.
In one implementation, client can not pre-save any compression dictionary under initial situation, to In the processing procedure of user data, compression dictionary only is obtained from server end, client development cost can be reduced.
Corresponding, the embodiment of the present invention additionally provides a kind of method for obtaining compression dictionary, applied to server end.Referring to Fig. 2, Fig. 2 are another flow chart of the method for the acquisition compression dictionary of the embodiment of the present invention, are included the following steps：
Step 201, the data message that client is sent is received.
Wherein, data message includes unpressed user data target corresponding with for asking unpressed user data Compress the request mark of dictionary.
In this step, server end can receive the data message from client, wherein, data message is included not The user data of compression and for ask the request of the corresponding targeted compression dictionary of unpressed user data identify, in this way, Server end can be identified according to the request, established the corresponding targeted compression dictionary of the unpressed user data and be sent to Client enables the client to be compressed user data processing using the targeted compression dictionary.
Step 202, targeted compression dictionary is established.
