Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of storage method of offline message, and referring to Fig.1, Fig. 1 is the storage side of offline message of the present invention
The flow diagram of method first embodiment.
The embodiment of the invention provides the embodiments of the storage method of offline message, it should be noted that although in process
Logical order is shown in figure, but in some cases, it can be to be different from shown or described by sequence execution herein
Step.The storage method of offline message includes:
Step S10, after server-side receives the message write request of the first client transmission, detection receives the message
Whether the second client of the corresponding message to be written of write request is in off-line state.
In embodiments of the present invention, the first client is message sending end, and the second client is message sink end, the first visitor
Family end and the second client can be mobile phone, tablet computer, laptop, palm PC, personal digital assistant (Personal
Digital Assistant, PDA) etc. the fixed terminals such as mobile terminals, and number TV, desktop computer.As the first visitor
When family end will send messages to the second client, the first client and server-side establish long connection, and are sent by length connection
Message write request is to server-side.Wherein, message write request is that the request into server-side is written in instant communication message, i.e.,
When communication information can be for wechat message, QQ message etc., it is to be understood that the first client be the end of transmission instant communication message
End, the second client are to receive the terminal of instant communication message.Long connection, multiple numbers can be continuously transmitted in a connection by referring to
According to packet, during connecting holding, if sent without data packet, both sides is needed to send out link detecting packet.
After server-side receives the message write request of the first client transmission, server-side detection receives message write-in and asks
Ask whether the second client of corresponding message to be written is in off-line state.It should be noted that in message write request,
Carry the instant communication message in server-side to be written, in the instant communication message, carry receive the instant messaging disappear
The device identification for ceasing client, can determine the second client corresponding with the first client by the device identification.Specifically, if
Standby mark can be to use the user name of the second client user and/or UUID (the Universally Unique of the second client
Identifier, Universally Unique Identifier), the user name of the second client user can be infused in instant communication software for the user
The account generated when volume, such as WeChat ID and QQ number.
It should be noted that in the present embodiment, server-side can be used Open Fire and build live collaboration server,
Tigase or Ejabberd etc. can be used and build live collaboration server, with realize server-side using different communication protocol with
The first client and the second client carry out message transmission.Open Fire be it is free, open source, based on can expand communication and
Presentation protocol (XMPP (Extensible Messaging and Presence Protocol, expansible communication and expression association
View)), using Java programming language develop live collaboration server.Tigase is a kind of NIO (New realized using Java
Input/Output frame) is communicated.Ejabberd is the instant communication server based on Jabber/XMPP agreement.
Further, step S10 includes:
Step a obtains the reception message and writes after server-side receives the message write request of the first client transmission
Enter the status indicator of the second client of the corresponding message to be written of request, and detects whether the status indicator is to identify offline.
Step b, if detecting, the status indicator is offline mark, it is determined that second client is in offline shape
State.
Specifically, after server-side receives the message write request of the first client transmission, server-side, which obtains to receive, to disappear
Breath write request correspond to message to be written the second client status indicator, and detection the second client status indicator whether
To identify offline.Wherein, there are two states marks for the second client, and one is offline marks, and one is online marks, offline
Mark and the specific manifestation form identified online are arranged according to specific needs, such as can set " 00 " for offline mark,
Line mark is set as " 11 ", or sets " 0FF " for offline mark, sets " FF " etc. for online mark.
If server-side detects that the status indicator of the second client is offline mark, server-side is determined at the second client
In off-line state；If server-side detects that the status indicator of the second client is online mark, server-side determines the second client
End is online.It should be noted that the user when the second client logs in the corresponding Instant Messenger of message write request
When believing software, its status indicator in server-side can be revised as identifying online by the second client from offline mark；When second
When the user of client exits the message write request corresponding instant communication software, the second client can be by it in server-side
Status indicator be revised as identifying offline from online mark.
Step S20, if detecting, second client is in off-line state, by the message to be written be determined as from
Line message.
When server-side detects that the second client is in off-line state, server-side by the message write request it is corresponding to
Write-in message is determined as offline message, i.e., is determined as disappearing offline by the corresponding instant communication message to be written of the message write request
Breath.
The offline message is written into preset memory database and preset non-relational database step S30,
And the validity period of the offline message is set in the memory database.
Offline message is written into preset memory database and preset non-relational database server-side, will be from
Line message store into memory database and non-relational database in, and in memory database be arranged offline message it is effective
Phase.In the present embodiment, offline message is stored into memory database and non-relational number using Key-Value data structure
According in library.Specifically, the name of Key is distinguished by fields such as user name, UUID and chat scenarios.Chat scenario include but
It is not limited to single chat scene, group chat scene and public platform chat scenario, the corresponding scene identity of different chat scenarios is different
, such as in the present embodiment, message can be set to the scene identity of single chat scene, set group chat scene for Notify
Scene identity, set public to the scene identity of public platform chat scenario.Such as with the instant messaging between two users
For message, i.e., by taking the corresponding instant communication message of single chat scene as an example, Key can be named are as follows: core:offline:message:
$ username+UUID $, wherein core is the abbreviation of instant communication message correspondence system, and offline indicates that the instant messaging disappears
Breath is offline message, and message is single chat scene identity, and username indicates to receive the user of the user of the instant communication message
Name, UUID are the Universally Unique Identifier for receiving the instant communication message client.Validity period, corresponding duration can be according to specific
It needs and is arranged, such as validity period corresponding duration can be set to 24 hours, 50 hours or 5 days.
Wherein, memory database can be the databases such as Redis and Memcached, be read by the high-performance of memory database
Write capability is to reduce the reading and writing data pressure of client.Redis is use ANSI (the American National an of open source
Standards Institute, American National Standards Institute (ANSI)) C language writes, support network, it is memory-based also can persistence
Log type and Key-Value database, and provide API (the Application Programming of multilingual
Interface, application programming interface).Memcached is a set of distributed fast taking system.Non-relational database can
For databases such as HBase and Cassandra.HBase be a high reliability, high-performance, towards column, telescopic distribution deposits
Storage system.Cassandra is a set of open source distribution NoSQL (Not Only SQL, non-relational database) Database Systems,
It is the database of the non-relationship an of mixed type.Such as when memory database is Redis, client is by offline message with Key-
The form of Value is written in the ZSET (Sorted Set, ordered set) of Redis.
The present embodiment is received by receiving the message write request of the first client transmission in server-side detecting
When the second client that message write request corresponds to message to be written is in off-line state, it is written into message and is determined as disappearing offline
Breath, which is written into preset memory database and preset non-relational database, and in memory database
It the validity period of middle setting offline message, avoids and stores offline message into the relevant database of server-side, utilize memory
The high-performance literacy of database improves the reading efficiency of offline message, and offline message is arranged in memory database
Validity period, and offline message is stored to non-relational database, it avoids that offline message being stored in server-side for a long time
In deposit data library, on the basis of guaranteeing that user successfully can obtain offline message, depositing for server-side memory database is saved
Space is stored up, and improves the reading efficiency of offline message.
Further, the storage method second embodiment of offline message of the present invention is proposed.
The storage method second embodiment of the offline message and the storage method first of the offline message apply the area of example
It is not, the storage method of offline message further include:
Step c determines the type of message of the offline message.
After server-side determines offline message, server-side determines the type of message of offline message.Wherein, server-side according to from
Scene identity in line message Key is the type of message that can determine offline message.When offline message corresponds to the scene identity in Key
For single chat scene scene identity when, server-side can determine offline message be single chat message；When offline message corresponds to the field in Key
When scape is identified as the scene identity of group chat scene, server-side can determine that offline message is group chat message；When offline message corresponds to Key
In scene identity be public platform chat scenario scene identity when, server-side can determine offline message be public platform chat disappear
Breath.It, in other embodiments, can will be offline it should be noted that the embodiment of the present invention does not limit the type of message of offline message
Message is set as other types.
It is described that the offline message is written to the step into preset memory database and preset non-relational database
Suddenly include:
Offline message classification is written into memory database according to the type of message by step d, and according to institute
It states type of message offline message classification is written into non-relational database.
After server-side determines the type of message of offline message, server-side writes offline message classification according to the type of message
Enter into the corresponding subdata base of memory database, and offline message classification is written to non-relational number according to the type of message
According in the corresponding subdata base in library, i.e., offline message is divided into single chat message, group chat message and public platform chat messages three classes and deposited
Storage is in the corresponding subdata base of memory database, and offline message is divided into single chat message, group chat message and public platform and is chatted
Its message three classes is stored in the corresponding subdata base of non-relational database, in order to the second client pull it is to be obtained from
In line message process, obtained from the subdata base of corresponding types according to the type of message of offline message to be obtained to be obtained offline
Message improves the acquisition efficiency that the second client obtains offline message.It should be noted that in memory database and non-relationship
In type database, it is respectively arranged with the subdata base that storage different messages type corresponds to offline message, i.e., a kind of type of message pair
Answer a subdata base.
Further, the storage method 3rd embodiment of offline message of the present invention is proposed.
The storage method second embodiment of the storage method 3rd embodiment and offline message of the offline message
Difference is, the storage method of offline message further include:
Step e, after detecting that the second client successfully logs in, detect in the memory database with the presence or absence of with it is described
The corresponding offline message to be obtained of second client.
Second client can be by requesting Login (login) service execution register.When the second client passes through Login
It services after successfully logging in, server-side can be detected the second client and successfully log in, at this point, the status indicator of the second client is
It is revised as identifying online from offline mark.After server-side detects that the second client successfully logs in, server-side detects memory number
According to whether there is offline message to be obtained corresponding with the second client in library, specifically, server-side can be held by Login service
Row inquiry instruction, which inquires the second client, whether there is offline message to be obtained.It should be noted that when the success of the second client
It logs in, server-side can obtain the user name of second client corresponding UUID and the second client user, if server-side detects
Exist into memory database and carry UUID Key corresponding with the user name, server-side, which then can determine in memory database, to be existed
Offline message to be obtained corresponding with the second client；If server-side detects not exist in memory database and carries UUID and be somebody's turn to do
The corresponding Key of user name, server-side then can determine in memory database in the presence of corresponding with the second client to be obtained offline
Message.
Step f, if there are the offline messages to be obtained in the memory database, it is determined that the memory database
In, the message number and type of message of the offline message to be obtained.
The type of message and the message number are sent to second client by step g, for second visitor
Family end obtains the offline message to be obtained according to the type of message and the message number in the server-side.
If detecting there are offline message to be obtained in memory database, server-side determines to be stored in memory database
Offline message to be obtained message number and type of message.Specifically, server-side can be corresponding by offline message to be obtained
Key determines the type of message of offline message to be obtained, and the Key quantity by carrying the second client UUID is determined wait obtain
Take the message number of offline message, and/or by carry the second client correspond to the Key quantity of user name determine it is to be obtained from
The message number of line message.It is understood that the message number of offline message to be obtained, which is equal in memory database, carries the
The Key quantity of two client UUID is also equal to carry the Key quantity that the second client corresponds to user name in memory database.When
Server-side determines that server-side will be to be obtained offline in memory database after the message number of offline message to be obtained and type of message
The message number and type of message of message are sent to the second client, so that the second client is according to the type of message and message count
Amount obtains offline message to be obtained in server-side.Wherein, message number can be the total quantity of offline message to be obtained, can also be
The corresponding message number of each type of message.
Further, the storage method of offline message further include:
Step h detects the non-relational number if there is no the offline message to be obtained in the memory database
According in library whether there is the offline message to be obtained.
If server-side detects there is no offline message to be obtained in memory database, server-side detects non-relational number
According in library whether there is offline message to be obtained.It should be noted that whether there is in server-side detection non-relational database
The process of offline message to be obtained is similar with the presence or absence of the process of offline message to be obtained in detection memory database, herein not
It is described in detail again.
Step i, if there are the offline messages to be obtained in the non-relational database, it is determined that the non-relational
In database, the message number and type of message of the offline message to be obtained.
The type of message and the message number are sent to second client by step j, for second visitor
Family end obtains the offline message to be obtained according to the type of message and the message number in the server-side.
If detecting, there are offline message to be obtained in non-relational database, server-side determines non-relational database
In offline message to be obtained message number and type of message, and the message number of offline message to be obtained and type of message are sent out
Give the second client, for the second client obtained in server-side according to the type of message and message number it is to be obtained offline
Message.It should be noted that server-side determines the message number and type of message of offline message to be obtained in non-relational data
Process and server-side determine that the message number of offline message to be obtained and the process of type of message are similar in memory database,
This is no longer described in detail.Further, if there is no offline message to be obtained in detection non-relational database, server-side is given birth to
There are the prompt informations of offline message by Cheng Wei, and the prompt information is sent to the second client, for the second client according to
The prompt information, which determines, does not have offline message in server-side.Wherein, after the second client receives offline message, the second visitor
Family end can show that the prompt information, the second client also may be selected not showing the prompt information in its display interface.
The present embodiment passes through when detect that the second client successfully logs in after, if detecting in memory database in the presence of with the
The corresponding offline message to be obtained of two clients, it is determined that the message number and message of offline message to be obtained in memory database
Type；If detecting, there is no offline messages to be obtained corresponding with the second client in memory database, but detect non-pass
It is that there are offline messages to be obtained in type database, it is determined that the message number of offline message to be obtained in non-relational database
And type of message, and type of message and message number are sent to the second client, so that the second client is according to type of message
Offline message to be obtained is obtained in server-side with message number, improves the success that the second client successfully obtains offline message
Rate, and by preferentially detecting whether that, there are offline message to be obtained, improving in detection service end is in memory database
It is no that there are the detection efficiencies of offline message to be obtained.
Further, the storage method fourth embodiment of offline message of the present invention is proposed.
