Make arrangements for his funeral end packet count it is identical, or storage position set midrange it is identical as the packet count of terminal to be pushed, and generation deposit
Storage space is the push mark for recording the push state of terminal to be pushed；
For each terminal to be pushed, it is performed both by following step:
Using preset hash function, the cryptographic Hash of the identity ID of the terminal to be pushed is calculated, waits pushing according to this
The cryptographic Hash of the ID of terminal determines the storage position of the ID mapping of the terminal to be pushed, and obtaining from determining storage position should be to
Push the push mark of terminal；
According to acquired push mark, determines and be somebody's turn to do whether terminal to be pushed does not push to PUSH message, if so, to this
Terminal push to be pushed is to PUSH message, and updates the push mark of the storage position record of the ID mapping of terminal to be pushed.
In conjunction with Fig. 1, the embodiment of the invention also provides a kind of information push method, this method is applied to server, such as Fig. 2
Shown, this method comprises the following steps:
Step 201, judge whether be greater than preset threshold to the corresponding total number of terminals to be pushed of PUSH message, if so, right
It is grouped to the corresponding terminal to be pushed of PUSH message.
In embodiments of the present invention, server can obtain the information such as position, hobby and the habit of user by terminal, so
Need to carry out the terminal to be pushed of message push according to these information selection a part afterwards.
It, can be according to the corresponding total number of terminals X to be pushed of PUSH message, with single bitmap in a kind of implementation
(bitmap) actual storage digit T in calculates the packet count N of terminal to be pushed by formula (1), then will be to PUSH message pair
The terminal to be pushed answered is divided into N group.
Wherein, actual storage digit T indicates that single bitmap can store pushing away for T terminals to be pushed in single bitmap
Mark is sent, push mark indicates whether terminal to be pushed has been pushed to PUSH message,The operation represented is takes upper integer.
Such as:
Illustratively, actual storage digit T can be set to 1000000 in single bitmap.
Step 202, according to the packet count of terminal to be pushed, the set of bitmap is generated.
Wherein, line number is identical as the packet count of terminal to be pushed in the set of bitmap or the set midrange of bitmap
Identical as the packet count of terminal to be pushed, storage position is used to record the push mark of the push state of terminal to be pushed.
In a kind of embodiment, N number of bitmap is generated, and stores initially pushing away for position record in the every bitmap generated
Sending mark is not push this to PUSH message (packet count that N is terminal to be pushed).Such as: it is each in N number of bitmap of generation
The initial push mark for storing position record is 0.
Step 203, calculate the ID's of terminal to be pushed using preset hash function for each terminal to be pushed
Cryptographic Hash determines the storage position of the ID mapping of terminal to be pushed according to the cryptographic Hash of the ID of terminal to be pushed, and deposits from determining
The push mark of terminal to be pushed is obtained in storage space.
Wherein, the push mark of terminal to be pushed is stored in bitmap, the pushed information that push mark indicates includes:
Push is to PUSH message or does not push to PUSH message.
In a kind of embodiment, preset first hash function can be utilized, is determined respectively to each terminal to be pushed
The target bitmap of the ID mapping of terminal to be pushed.Then it according to preset second hash function, determines in target bitmap,
The target of the ID mapping of terminal to be pushed stores position, and reads push mark from determining target storage position.
Step 204, whether not terminal to be pushed is determined according to the push mark of acquisition for each terminal to be pushed
It is pushed to PUSH message, if so, pushing to terminal to be pushed to PUSH message, and updates the ID mapping of terminal to be pushed
Storage position record push mark.
In a kind of embodiment, if the push mark of the terminal to be pushed read from the target storage position in target bitmap
It is to have pushed, it is determined that terminal to be pushed has been pushed to PUSH message.If being read from the target storage position in target bitmap
The push mark of the terminal to be pushed taken, which is not all, have been pushed, it is determined that terminal to be pushed is not pushed to PUSH message.If to
Push terminal is not pushed to PUSH message, then the push mark of the target storage position record mapped the ID of terminal to be pushed is equal
It is updated to push, and pushes to terminal to be pushed to PUSH message.If terminal to be pushed has been pushed to PUSH message, no
To the terminal push to be pushed to PUSH message.
In embodiments of the present invention, it is understood that there may be a storage position stores the feelings of the push mark of multiple terminals to be pushed
Condition, so only can just be determined wait push away when the push mark of the target storage position record wait push terminal is to have pushed
It makes arrangements for his funeral to hold and be pushed to PUSH message.
Illustratively, it is that " 1 " indicates to have pushed that push mark, which can be set, and push mark is that " 0 " indicates not push.
Optionally, pushing to the terminal to be pushed not being pushed to PUSH message to the mode of PUSH message includes following three
Kind mode:
Mode one determines whether terminal each to be pushed is not pushed to PUSH message respectively, if so, updating wait push
The push mark of the storage position record of the ID mapping of terminal.Determined to the corresponding each terminal to be pushed of PUSH message whether
It is not pushed after PUSH message, pushes to the terminal to be pushed not being pushed to PUSH message to PUSH message.
Mode two determines whether terminal each to be pushed is not pushed to PUSH message respectively, if so, updating wait push
The push mark of the storage position record of the ID mapping of terminal, then to the terminal push to be pushed to PUSH message.
Mode three determines whether terminal each to be pushed is not pushed to PUSH message respectively, if so, judging to wait push away
It makes arrangements for his funeral and holds what is pushed whether to push success to PUSH message.If so, pushing away the target storage position record in target bitmap
Mark is sent to be updated to push.
It is understood that illustrating terminal to be pushed if pushing successfully to what terminal to be pushed pushed to PUSH message
It has received to PUSH message, needs to update push mark.And pushing to PUSH message for pushing to terminal to be pushed fails, then
Illustrate that terminal to be pushed does not receive to PUSH message, does not need to update push mark.
It is understood that be not pushed after PUSH message determining wait push terminal, it in time will terminal be pushed
The push mark of the target storage position record of mapping is changed to push, and is in order to avoid identical terminal to be pushed is read again
When pushing the push mark of target storage position record of terminal, the push mark read causes because updating not in time for this
Read mistake push mark so that should terminal be pushed have received it is duplicate to PUSH message.
As it can be seen that using information push method provided in an embodiment of the present invention, due to corresponding each to PUSH message
Before terminal push to be pushed is to PUSH message, it can be reflected according to the cryptographic Hash of the ID of terminal to be pushed, the ID for obtaining terminal to be pushed
The push mark for the storage position record penetrated.Then according to acquired push mark, determine whether terminal to be pushed is not pushed
It to PUSH message, pushes to the terminal to be pushed not being pushed to PUSH message to PUSH message, and updates terminal to be pushed
The push mark of the storage position record of ID mapping, in this manner it is possible to avoid to the terminal to be pushed being pushed to PUSH message
The case where being pushed again to PUSH message.
Optionally, the method for generating N number of bitmap in conjunction with Fig. 3, above-mentioned steps 202 are as follows: according to formula (1), determination is used for
The bitmap total number N for recording the push mark of terminal to be pushed determines that the expectation of single bitmap is deposited further according to formula (2)
Then storage space number M initializes the quantity of bitmap, according to the expectation storage bit number M of single bitmap according to bitmap total number N
The storage bit number of each bitmap is initialized, the set of storage position is generated.
Wherein, the initial push mark of each storage position record in the bitmap of generation is not push.Such as: it will generate
Bitmap in each storage position record initial push mark be disposed as " 0 ".
In a kind of implementation, pass through the expectation storage bit number M that formula (2) calculate single bitmap:
Wherein, the expectation storage bit number M of single bitmap indicates the recordable M push mark of single bitmap, individually
Actual storage digit T indicates that single bitmap can store the push mark of T terminals to be pushed, expected error rate in bitmap
P is that the push mark for allowing to record in bitmap the probability of mistake occurs, and illustratively, expected error rate P can be 0.01%.
In embodiments of the present invention, if probably being made since the expectation storage bit number of single bitmap is set as T
At the same storage position stores the push mark of multiple terminals to be pushed, and push mark is caused to be determined mistake.Such as: to
The push mark of push terminal A and terminal B to be pushed all is recorded in storage position 1, if terminal A to be pushed has been pushed wait push
Message, then storing the push mark recorded in position 1 is to have pushed, if terminal B to be pushed is not pushed to PUSH message, is being inquired
Reading the push mark in storage position 1 when pushing the push mark of terminal B is to have pushed, and leads to pushing away for terminal B to be pushed
Mark is sent to be determined mistake.In order to avoid this case occurs, can be made by the expectation storage bit number of the single bitmap of increase
The push mark for obtaining each terminal to be pushed is stored in as far as possible in different storage positions.
As it can be seen that the push mark to the corresponding terminal to be pushed of PUSH message is all recorded in one with the prior art
Method in bitmap is compared, in the embodiment of the present invention, by will be to the push mark of the corresponding terminal to be pushed of PUSH message
It is separately recorded in N number of bitmap, so that the expectation storage bit number M of single bitmap is smaller, so that looking into single bitmap
It askes or the time of write-in is reduced, so the speed of message push can be improved using the embodiment of the present invention.
In embodiments of the present invention, due to being to create bitmap in database (Redis), and Redis is executing program
When be single thread execute, it is possible to when avoiding from bitmap while searching the identical push mark wait push terminal, push away
The situation for sending result to be determined mistake.Such as: if terminal A to be pushed was not pushed to PUSH message, terminal A's to be pushed
The push mark in storage position 1 that ID maps in bitmap is not push, when two terminal A to be pushed are simultaneously in storage position 1
When middle reading push mark, then the push mark of one of them terminal A to be pushed first is determined, then pushing away terminal A to be pushed
Mark is sent to be changed to push.It, then can be by another terminal A to be pushed when searching another when pushing the push mark of terminal A
It is determined as having pushed to PUSH message.
In addition, the embodiment of the present invention can also determine multiple pushing away to the corresponding terminal to be pushed of PUSH message parallel
Mark is sent, at this point, the method for generating bitmap are as follows: according to the corresponding total number of terminals to be pushed of PUSH message A, B and C,
It calculates separately to the corresponding bitmap total number of PUSH message A, B and C, then basis is respectively corresponded to PUSH message A, B and C respectively
Bitmap total number and the desired storage bit number M of single bitmap, generate bitmap.Also, it is each in the bitmap generated
The initial push mark for storing position record is not push.The bitmap of generation is referring to table 1:
Table 1
Wherein, A:0, A:1 and A:2 indicate to be divided into three groups to the corresponding terminal to be pushed of PUSH message A, and create three
A bitmap, for recording the push mark to the corresponding terminal to be pushed of PUSH message A.Similarly, B:0 is indicated to PUSH message
The corresponding terminal quantity to be pushed of B is less, is grouped, can create so not treating the corresponding terminal to be pushed of PUSH message B
One bitmap is used to record the push mark to the corresponding terminal to be pushed of PUSH message B.Similarly, C:0, C:1, C:2 and C:3
It indicates to be divided into four groups to the corresponding terminal to be pushed of PUSH message C, creates four bitmap, for recording to PUSH message
The push mark of the corresponding terminal to be pushed of C.
As it can be seen that the embodiment of the present invention and the prior art will all be recorded in one to the corresponding terminal to be pushed of PUSH message
Method in bitmap is compared, and due to that can create multiple bitmap in embodiments of the present invention, and each bitmap can
To be stored in different servers, in this way, due to the limited length for the bitmap for allowing to store in a server, so existing
The number of terminals to be pushed for having technology that can filter is limited, and the embodiment of the present invention can be stored with different servers, each clothes
It can store one or more bitmap in business device, to increase in information push method using this hair embodiment may filter that
Terminal to be pushed quantity.
Optionally, referring to fig. 4, the method for the reading of above-mentioned steps 203 push mark includes:
Step 401, using preset first hash function, the first cryptographic Hash of the ID of terminal to be pushed is calculated.
The first hash function can be preset hash function in embodiments of the present invention, and the ID of terminal to be pushed can be
When should establish connection with server for the first time wait push terminal, number of the server to terminal setting to be pushed.
Step 402, it according to the number of packet of the first cryptographic Hash of the ID of terminal to be pushed and terminal to be pushed, determines wait push away
The target bitmap that the ID at end that makes arrangements for his funeral maps.
In a kind of implementation, by formula (3), the target bitmap of the ID mapping of terminal to be pushed is calculated:
Rx=hash (id) %N (3)
Wherein, RxThe first cryptographic Hash of the ID of terminal to be pushed is indicated for X bitmap, hash (id), and % expression takes
Remaining operation, N are the number of packet of terminal to be pushed.
Step 403, according to preset second hash function, the second cryptographic Hash of the ID of terminal to be pushed is calculated.
Wherein, the quantity K of the second cryptographic Hash of the ID of terminal to be pushed is calculated by formula (4):
Wherein, M is the expectation storage bit number of single bitmap, and T is actual storage digit in single bitmap.
In embodiments of the present invention, preset K the second different hash functions be can use, terminal to be pushed is calculated
K the second cryptographic Hash of ID.
Step 404, according to the expectation storage bit number of second cryptographic Hash of the ID of terminal to be pushed and single bitmap, really
It is scheduled in target bitmap, the target of the ID mapping of terminal to be pushed stores position.
It in a kind of embodiment, is calculated in target bitmap by formula (5), the target of the ID mapping of terminal to be pushed
Store position Cy:
Cy=fy(id) (5) %M
Wherein, CyFor y-th of storage position, fy(id) the second cryptographic Hash of the ID of terminal to be pushed is indicated, % indicates remainder fortune
It calculates, M is the expectation storage bit number of single bitmap.
Step 405, the push mark of terminal to be pushed is read from target storage position.
Illustratively, referring to Fig. 5, it is assumed that the corresponding target bitmap of terminal A to be pushed is Rx=3.In target bitmap
In, 3 targets of the ID mapping of terminal A to be pushed store position Cy=2 or 5 or 7, then terminal A to be pushed reflects in bitmap
The storage position penetrated are as follows: second, the 5th and the 7th storage position of third bitmap, the push mark of reading be respectively as follows: " 1 ",
" 0 " and " 1 ".
