The method of the cross-platform data communication, comprising:
Step S101 obtains data information.
In the present embodiment, the acquisition data information, can realize in the following way: server end is from database
Obtain the data information.
It should be noted that the data information be in the database stored in the form of database table, if with
A record is described in dry field, so the data information obtained in this step is deposited by the data information
The value of field name and field in the database table of storage forms, and the data information furthermore obtained in this step can be with
It is the combination of a record or several records.
It should be understood that needing to access corresponding number according to the demand of user when accessing database acquisition data information
According to Ku Biao to obtain corresponding data information, need first to determine the type and inquiry ginseng of the required data information of user
Number, so including the following steps: before executing the step of step S101 obtains data information
Based on the network layer interface that C or C++ is realized, the request for the acquisition data information that the receiving end is sent is received.
It should be noted that since the method for cross-platform data provided by the present application communication realizes cross-platform network
Communication, by taking there are two big Mainstream Platform ios and android in current mobile terminal as an example: due to the programming language Java of Android system
It can be interacted with C language and C Plus Plus with the programming language object-c of ios, so the net realized based on C or C++
When network layers interface, it can also be communicated by the network layer interface between different two platforms of system.The receiving end is
One end for receiving the information of the server end feedback includes at least following 3 according to the difference of the operating system of receiving end
Kind client: android client, ios client or window client.
In the present embodiment, the network layer interface realized based on C or C++ is: being c++ based on open source projects curl and connects
The unified encapsulation of mouth.Wherein, encapsulation refers to: the attribute and realization details of hidden object, only external disclosure interface, controls in program
The access level of reading and the modification of middle attribute；The data abstract obtained and behavior (or function) are combined, that is, by data
It is organically combined, is formed " class ", wherein data and function are all the members of class with the source code of operation data.
Specifically, being to pass through when the request for the acquisition data information that receiving end described in the received server-side is sent
HTTP transmits the request for obtaining data information.Wherein, HTTP is used to obtain data from server end, is that a kind of build exists
Simple protocol on TCP/IP.HTTP allows to send data from client.HTTP is some ASCII texts
Row, these ASCII texts are sent to server end from client to request a special operation.Then, server end is being sent out
Some literal lines are responded before giving the actual request content of client.Such as: client (curl) sends a HTTP and asks
Ask, the request include operating method (such as: GET), server end is based on HTTP request and responds a statusline (showing to grasp
Make whether result succeeds) and response message body, the message body portion is exactly that (server end is based on for the real data requested
Obtain the corresponding data information that the request of data information is inquired from database table).
The acquisition process for obtaining data information is described in detail below by a specific example.
There are 2 database tables in the database, one is film information table, and one is personnel's information table, wherein described
Film information table includes following field:
| Number | Movie name | Director | Show the date |
| 1 | ABC | Aa | 1.10 |
| 2 | QWE | Bb | 1.20 |
The personal information table includes following field:
| Work number | Name | Gender | The length of service |
| 1 | aa | Male | 1 |
| 2 | bb | Female | 2 |
If the network layer interface that the server end is realized based on C or C++, the acquisition number of the received receiving end transmission
It is believed that the query argument for including is director Aa in the request of breath, then it is to direct when executing step S101 acquisition data information
Aa determines film information table as the database table in parameter query database, according to director's field, determines and corresponds to further according to Aa
Record.
Step S103 instantiates the data information with preset data format, generates and carries the corresponding number
It is believed that the intermediate file of the data object of breath.
In the present embodiment, described that the data information is instantiated with preset data format, generate carrying pair
The intermediate file of the data object of the data information is answered, can be realized in the following way: with institute in pre-set class
Data information is stated as parameter and creates data object, and the class of data object will have been created as intermediate file.
It should be noted that the instantiation refers to: in the programming of object-oriented, usually the mistake with class creation object
Journey is known as instantiating, the process of instantiation be exactly for the process in object storage allocation space, with keyword new create one it is new right
As format is as follows:
Class name object name=new class name ([parameter list])；
Such as Date date=new Date ()；As soon as exactly creating the object for showing the date with date class, cry pair
The instantiation of elephant.
It is described that the data information is instantiated with preset data format, it generates and carries the corresponding data information
Data object intermediate file, specifically comprise the following steps:
It obtains pre-set for storing the class of the data information；
The value of field in the data information is stored in the class；
Using the class after instantiation as the intermediate file.
It should be noted that it is described pre-set for storing the class of the data information, it is to be given birth to by .proto file
At class.Object only is stated in the class, does not distribute it complete memory headroom.The statement object is
Refer to: when a computer program needs to call memory headroom, the occupy-place that memory issues being instructed.Statement is only by object name
(user identifier) tells compiler for information about, but does not cause the distribution of memory, only by variable representated by object name
It regards a reference to variable as, and distributes required memory headroom for it, its occupied space is far smaller than the object of a class
Required space, but the object stated cannot use at once, it is also necessary to it is instantiated.
It should be understood that the class only notifies compiler to need to prepare great memory headroom, its unpromising distribution
Memory headroom.It, just can real committed memory space after only creating object with class.
It is according in step when executing the step for obtaining the pre-set class for storing the data information
The data information obtained in S101 obtains the corresponding pre-set class for being used to store the data information, specifically,
It can be obtained according to the field name in the data information corresponding pre-set for storing the class of the data information.
Above-mentioned example is continued to use below the class for storing the data information of setting is described in detail.
By pre-set for for storing the class of the data information to film information table:
Film information includes as properties:
Number: number (uses integer representation)
Movie name: name (uses string representation)
Director: director (uses string representation)
Duration: time (is indicated) with the date
It is realized using Protobuf and class is generated with .proto file (movie.proto), add one in .proto file
The message structure of a entitled Movie, for describing the structural data in communications protocol.The content of this document approximately as:
Movie message format has 4 fields, and the data information carried in the message corresponds respectively to each field.Its
In each field have a name and a seed type.
In the above example, all fields are all scalar types: an integer (number), a date (date),
Two string types (name and director).
As above-mentioned file format, in message definition, each field has a unique identifier.These identifiers
It is that cannot change again for identifying each field in the message once using.[1,15] identification number within exists
A byte can be occupied when coding.
Specified message field modifier includes one of following:
Required: the field that not can increase or delete is indicated；
Optional: the field can have 0 or 1 value (being no more than 1) in message format.
Repeated: in the good message of format, this field may be repeated any multiple of times (including 0 time).Weight
The sequence of multiple value can be retained.Indicate the List that the value can repeat, and be equivalent in Java.
Each above-mentioned message can respectively correspond a .proto file.
It should be noted that the class is just preset before executing the step of step S101 obtains data information
, the above-mentioned example provided is only schematical, in specific implementation, can preset correspondence with the combination of part field
Class, it is same for being that other database tables in database are also required to preset corresponding class, due in setting
Only field type and field name difference, so details are not described herein.
Due to only stating object in the class of acquisition, there is no distribute it complete memory headroom, institute
To need to instantiate the object in the class, so executing the value by field in the data information, storage
It is that the value of field in the data information is assigned to the field that the value is corresponded in the class when step in the class
The object of title completes instantiation process.Specifically, GET method can be used, field is obtained from the data information
Value, carries out assignment in the class.
It is shown since what is got in the acquisition data information is that record has the record for directing Aa when carrying out assignment
The value that field will be obtained from the data information is that number 1 is assigned to number, is incited somebody to action when carrying out assignment in the class
Movie name ABC is assigned to name, director Aa is assigned to director and duration 1.10 is assigned to date.
In the present embodiment, the intermediate file includes: proto file；The proto file is Protobuf data
Define file.
Step S105 sends the intermediate file to the receiving end of data information described in demand.
In the present embodiment, described to send the intermediate file to the receiving end of data information described in demand, it can use
Under type is realized: server end is formed in step s 103 by the receiving end transmission of data information as described in HTTP to demand
The intermediate file.
Specifically, described send the intermediate file to the receiving end of data information described in demand, it is real based on C or C++
Existing network layer interface sends the intermediate file to the receiving end of data information described in demand.
It should be noted that the receiving end is one end for receiving the intermediate file that the server end is sent, root
According to the difference of the operating system of receiving end, include at least following 3 kinds of clients: android client, ios client or
Window client.
When execution step S105 sends the intermediate file to the receiving end of data information described in demand, in order to improve number
According to efficiency of transmission, reduce the transmission quantity of data, the technical solution of the present embodiment provides a kind of preferred embodiment, is executing
Before step S105 sends the intermediate file to the receiving end of data information described in demand, the intermediate file is pressed
Contracting.
It is described that the intermediate file is compressed, it can realize in the following way:
Serializing operation is executed to the intermediate file according to the library Protobuf, obtains binary data string.
It should be noted that the serializing operation refers to: object serialization (Serialization) technology, being will be right
Image data is converted into the technology of another perdurable data form, i.e., being converted to the status information of object can store or transmit
Form process.During serializing, its current state is written to interim or persistent storage area by object, can by from
The state of reading or unserializing object in memory block, re-creates the object.In order to enable the data energy after storing and transmitting
Enough objects become again in memory again, such conversion must be reversible.Sequencing method and unserializing method are extensive
Using in inter-network data is transmitted and is applied, it usually needs convert the information into data flow, realize data transmission and application.Class
As, unserializing extracts data from the representation of serializing, and Obj State is directly arranged.
Above-mentioned example is continued to use below intermediate file execution serializing operation is described in detail.
For carrying out the intermediate file after assignment:
Using protoc compiler, the intermediate file is compiled, (Protobuf agreement also supports Java language by taking C++ as an example
Speech, Python, can change corresponding type into) .h and .cc text can be generated after being compiled to the intermediate file
Part .h are that the statement .cc of class is to realize.
Due to having many fields, the format of each field in the message of Protobuf are as follows: modifier field type field
Name=domain number；The intermediate file is executed by the library Protobuf again when serializing, according to TLV, (T is Protobuf consultation
Key, V are the corresponding value value of field, and L is the length of Value) binary format serialize each field, after serializing
Value be to save as it is, Key is saved according to certain switch condition, and the result after serializing is exactly
KeyValueKeyValue….The serialization format of Key is turned according to the subsequent domain number of field in message and field type
It changes.
Message structure in traverse object, and serialize each field in Message, method approximately as:
Movie movie；
movie.set_number("1")；
movie.set_name("ABC")；
movie.set_director("Aa")；
movie.set_time("1.10")；
movie.SerializeToOstream()；
The serialization process of the intermediate file is briefly described by taking Java language as an example below.
By calling wirteTo () method in the raw class GenerateMessage of compiling to start the byte after serializing
It is written in output stream.Wherein, GenerateMessage inherits AbstractMessage class, and serializing finally exists
It is completed in AbstractMesssage, the realization process of serializing is as follows:
Call writeTo () method in AbstractMessage class, the Message structure () in traverse object；
Call writeMessageSetExtension () method in CodeOutputStream class, serializing
Each field in Message.
It should be understood that generating compressed to the intermediate file two due to serializing the intermediate file
Binary data string, so being when execution step S105 sends the intermediate file to the receiving end of data information described in demand
The binary data string after the intermediate file serializing is sent to the receiving end of data information described in demand.
