Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
Referring to fig. 1, an embodiment of the present invention provides a method for implementing high-performance communication between modules, including the following steps:
step S1, defining the protocol header of the communication protocol to contain the following field information: the method comprises the steps of encoding format (Charset), protocol body Length (Length), protocol body DATA Type (Type), Sender (Sender), Receiver (Receiver), protocol body MD5 check Length (MD5_ LENGTH), protocol body MD5 value (MD5), sending TIME (SEND _ DATA _ TIME) and encryption Algorithm (AES), wherein the field information forms description information of a protocol body.
Specifically, the Charset field information is used to indicate the coding format of the data content in the protocol body. In this embodiment, the Charset field information is designed in the protocol header to be compatible with data transmission in different languages. For example, the encoding format of GB2312, GBK or UTF8 is commonly used in chinese; common English is in ASCII encoding format. When the communication between the modules is carried out, the protocol body needs to be decoded according to the coding rule designed by the protocol when the receiving party analyzes the protocol body.
Length field information, which is used to indicate the Length of the protocol body, so that the receiver can obtain the Length of the whole protocol body by analyzing the protocol header. For the receiving party, when the protocol body containing the data content is very huge, some special means may be adopted to analyze the protocol body, and the Length field information is designed for the receiving party to conveniently and rapidly query the size of the protocol body and improve the analysis efficiency.
Type field information for indicating the Type of data in the protocol body.
And Sender field information, which is used for indicating the Sender of the data and indicating which object or which module the data is originated from.
The Receiver field information is used for indicating a data Receiver and indicating which module or class the data Receiver is, and mainly describes relevant information of the Receiver.
MD5_ LENGTH field information indicating how many bytes in the data to calculate when calculating the MD5 value. This field is designed because if the protocol body is very large, it is very inefficient if both the sender and receiver compute MD5 to check the integrity of the data. However, in order to guarantee both integrity checking and performance of the data, a strategy of intercepting part of the data to compute MD5 is adopted. That is, the meaning indicated by this field is to intercept the length of the protocol body for computing MD5, and the default value is the full-computation protocol body MD5 value by default.
MD5 field information, MD5 value for representing the calculation data. The method is mainly used for verifying the integrity of the data and plays a certain encryption role at the same time.
SEND _ DATA _ TIME field information for indicating the transmission TIME of DATA. The field is designed to be used for later data statistics, and the time used for data distribution can be counted.
AES field information to indicate whether the protocol body is to be encrypted using the AES algorithm. The field is designed mainly in consideration of the information security related situation, for example, a certificate is needed when AES is used for encryption, and if the AES field is set in the protocol header information, the receiver decrypts the content of the protocol body by using the corresponding certificate.
It can be understood that, in the embodiment of the present invention, the protocol header of the communication protocol is optimally designed, so that it can: 1) the method supports multiple coding formats and is compatible with data transmission of different languages; 2) supporting a plurality of data types; 3) the data verification function is supported, and the verification function can ensure the integrity verification of data and the communication performance; 4) and the AES encryption function is supported, and the information security is improved. The protocol head of the communication protocol which is optimally designed can support the multiple functions, almost covers most communication use purposes and requirements, and therefore the universal requirement of the communication protocol can be met. Moreover, through the design of the protocol header, a receiving party can obtain the description information of the protocol body (namely, the abstract description of the data is generally known) without analyzing the protocol body, thereby improving the analysis capability of the whole data and realizing high-performance communication.
Further, in this embodiment, the data types in the Type field include the following:
the JSON type represents that data in a protocol body is character string data in a JSON format, and is mainly used for transmitting some basic information;
the FILE/PNG type represents that the data in the protocol body is binary data in the PNG picture format;
the FILE/jpeg type represents that the data in the protocol body is binary data in a jpeg picture format;
the FILE/RAW type indicates that the data in the protocol body is native binary data;
the XML type represents that the data in the protocol body is data in an XML format;
and a USER _ default type which indicates that the data in the protocol body is the customized data content.
Through the design of the data types, when the communication protocol designed and defined by the embodiment of the invention is used for the communication between the modules, the invention can support various types of data transmission, can perfectly be compatible with the data contents of JSON, XML, binary system and the like which are commonly used at present, and even has self-defined protocol content information, and has high universality and wide application range.
Further, in order to facilitate fast searching or identifying of protocol headers in a communication protocol, a protocol header identifier is added to the front of the protocol header. In the embodiment of the present invention, the protocol header identifier is @ head:
step S2, defining the protocol body of the communication protocol as two parts including data type and data content; the data type corresponds to a protocol body data type in a protocol header, the data content is represented in the form of key value pairs (key value), a single-byte key value pair identifier is added in front of each key value pair and behind the last key value pair, and the key value pair identifier can not only mark the beginning of each key value pair information, but also be used as a separator to distinguish adjacent key value pairs.
It will be appreciated that the most widely used data transmission format at present is typically the JSON format. Although data in the JSON format is also stored by key-value pairs, the JSON format requires that encapsulation of all data requires the use of "{ }" to define the start and end positions of each piece of data, for example: { key1 value1 }. In the embodiment of the invention, only one-byte key-value pair identifiers are added in the data content before each key-value pair and after the last key-value pair, and identifiers or separators are not required before and after each key-value pair. Thus, by comparison, it can be seen that the protocol body designed by the embodiment of the present invention occupies a channel and a memory length that is one less than those of the existing JSON format when the same key-value pair data is expressed. If the data content of the protocol body consists of 100 key value pairs, the memory and channel range occupied by the protocol body designed by the embodiment of the invention is 100 characters less than that of the existing JSON format, so that the protocol body designed by the embodiment of the invention has higher transmission efficiency and smaller memory occupation when used for inter-module communication. The advantage is more obvious when the content of the transmitted data is larger.
Further, in this embodiment, since the protocol body data Type in the protocol header includes six types, i.e., JSON, FILE/PNG, FILE/jpeg, FILE/RAW, XML, and USER _ default, and the data Type in the protocol body corresponds to the protocol body data Type in the protocol header, when the data Type in the protocol body corresponds to the above six types, the information of the data content represented by the correspondence is as follows:
when the data type in the protocol body corresponds to the JSON type, the data content record in the protocol body is represented by the specific content information in the JSON format;
when the data type in the protocol body corresponds to the FILE/PNG type, the complete binary data information of the PNG picture is recorded in the data content in the protocol body;
when the data type in the protocol body corresponds to the FILE/jpeg type, the complete binary data information of the jpeg picture is recorded in the data content in the protocol body;
when the data type in the protocol body corresponds to the FILE/RAW type, the data content in the protocol body is represented as the native binary data information;
when the data type in the protocol body corresponds to the XML type, the data information in the XML format is recorded in the data content of the protocol body;
when the data type in the protocol body corresponds to the USER _ default type, the data content record in the protocol body is represented by the self-defined data information.
Furthermore, in this embodiment, the key-value pair identifier is @, and the presentation form of the data content is: @ key 1@ value1@ key 2@ value2@ key 3@ value3 @.
In addition, in consideration of the convenience of quickly searching or identifying the data type and the data content in the protocol body, a data type identifier is added in front of the data type, and a data content identifier is added in front of the data content. In the embodiment of the present invention, the data type identifier is @ t ═ t; the data content identifier is @ d ═ d. On this basis, for better understanding of the defined protocol body, taking the USER _ DEFINE type as an example, when the data content includes multiple pieces of data, the corresponding complete protocol body is represented as follows:
@t=USER_DEFINE@d=@key1=value1@key2=value2@key3=value3……
where @ t ═ USER _ default indicates that the data type is a custom data type; @ d ═ indicates the start of the data content; @ key1 ═ value1 is a piece of data information, and by designing such a data structure, a set of entities capable of transmitting and receiving arbitrary character information can be obtained.
Step S3, when the inter-module communication is required, the data communication is performed between the modules according to the communication protocol having the protocol header and the protocol body defined above.
Referring to fig. 2, an embodiment of the present invention further provides a system for implementing high performance communication between modules, where the system includes a protocol header defining module, a protocol body defining module, and a communication processing module, which are connected in sequence.
Wherein the protocol header definition module is configured to: the protocol header of the communication protocol is defined to contain the following field information: the method comprises the steps of encoding format, protocol body length, protocol body data type, a sending party, a receiving party, protocol body MD5 check length, protocol body MD5 value, sending time and encryption algorithm, wherein the field information forms description information of the protocol body.
The protocol body definition module is used for: defining a protocol body of a communication protocol as two parts including a data type and a data content; the data type corresponds to the protocol body data type in the protocol header, the data content is expressed in the form of key-value pairs, and a single-byte key-value pair identifier is added in front of each key-value pair and behind the last key-value pair.
The communication processing module is used for: when the inter-module communication is needed, the data communication is performed among the modules according to the protocol header and the protocol body (i.e. the communication protocol) defined by the protocol header definition module and the protocol body definition module.
