Description

Technical Field

[0001] The present invention relates to the technical field of electronics and computer data processing, and in particular to a method and device for encapsulating and parsing data in message transmission. Background Art

[0002] Computer network protocols, as the cornerstone of building a network communication system, are usually divided into seven layers. Among these seven layers, the transport layer plays a crucial role. It mainly relies on TCP / IP or UDP protocols and is dedicated to solving the problem of transmitting network packets. At this layer, the focus is not on the specific data type, but on how to efficiently and accurately complete the data transfer.

[0003] Generally speaking, when building business applications, most application layer systems are established on the basis of transport layer protocols. During the interaction process of the application layer, in order to ensure the accurate expression and efficient processing of data, a series of basic data types are usually defined, such as integer (int), double-precision floating-point type (double), single-precision floating-point type (float), string, and binary array, etc. These data types provide basic specifications for data exchange in the application layer. These basic types are usually of variable length, so generally a field is required to identify its length during transmission.

[0004] However, during data transmission, especially through a narrow-bandwidth transmission link, the transmission efficiency and quality of these basic data types often become a key issue to be considered. When defining common application protocols, a challenge is often faced, that is, how to effectively transmit a data block with an uncertain data type and variable length in a message, which is particularly common in the application layer. Although the key-value pair method can meet the basic transmission requirements, in today's pursuit of efficient transmission, it is not the most ideal choice. Using one encoding method for each message to transmit various data types, and the encoding methods for different data types are the same, which causes resource waste, leads to a decrease in transmission efficiency, and even affects the performance of the entire application system.

After encoding, the largest data is represented by the smallest number of transmission bytes, reasonably utilizing resources, improving the transmission efficiency, and enhancing the performance of the application system.

[0071] Other features and advantages of the present invention will be described in the following specification, and, in part, will be obvious from the specification, or will be understood by implementing the present invention. The objectives and other advantages of the present invention can be realized and obtained by the structures specifically pointed out in the written specification, claims, and drawings.

[0072] The technical solutions of the present invention will be further described in detail below through the drawings and embodiments. Description of the Drawings

[0073] The drawings are used to provide further understanding of the present invention, and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention, and do not constitute a limitation to the present invention. In the drawings:

[0074] Figure 1 It is a schematic flowchart of a data encapsulation method and a parsing method in message transmission provided by an embodiment of the present invention;

[0075] Figure 2 A block diagram schematic of a method for encapsulating data in message transmission and a parsing device provided by an embodiment of the present invention. Detailed implementation manners

[0076] The following further describes the present invention in detail with reference to specific embodiments, but the implementation manners of the present invention are not limited thereto.

[0077] As Figure 1 shown, a first aspect of an embodiment of the present invention provides a method for encapsulating data in message transmission, which is applied to a message sender and includes the following steps:

[0078] Step 11, determining an encoding mode according to the attributes and transmission mode of application data.

[0079] Step 12, encoding the application data according to the encoding mode, variant data type, and value of the custom encoding value to generate a target message.

[0080] Among them, different attributes and transmission modes correspond to different encoding modes; the value of the custom encoding value indicates an empty string and its value or a non-empty value boolean type and its value; the transmission mode is included in the target message.

[0081] Step 13, transmitting the target message to the message receiver.

[0082] In this embodiment, different encoding modes are used to encode application data according to the attributes and transmission mode of application data, so that different data types of application data are encoded using different encoding modes, and the same data type can further be encoded using different encoding modes. After encoding, the largest data is represented by the smallest number of transmission bytes, avoiding resource waste caused by using the same encoding (for example, if smaller-length data is also encoded using a larger fixed length, it will cause resource waste), and rationally utilizing resources. At the same time, the same transmission mode can use different encoding methods according to actual needs, further rationally utilizing resources, improving the transmission efficiency, and enhancing the performance of the application system.

[0083] A second aspect of an embodiment of the present invention provides a method for encapsulating data in message transmission, including the following steps:

[0084] Step 21, the message sender determines an encoding mode according to the attributes and transmission mode of application data.

[0085] In this step, different attributes and transmission modes of application data can correspond to different coding modes. The message sender can determine which category each field or each type of field of the application data belongs to, determine the type of the transmission mode, and which conditions other attributes meet, so as to automatically match the corresponding coding mode. The transmission mode can be set as needed. The present invention represents more specific field types of application data in the form of variant data types.

[0086] Through a mapping table, fixed numerical values are used to correspond to basic data types, as shown in Table 1 specifically:

[0087]

[0088]

[0089] Table 1

[0090] Step 22, the message sender encodes the application data according to the coding mode, variant data type, and value of the custom coding value to generate a target message.

[0091] Among them, different attributes and transmission modes correspond to different coding modes; the value of the custom coding value indicates an empty string and its value or a non-empty value boolean type and its value; the target message includes the transmission mode.

[0092] In this step, the application data is encoded after determining the coding mode of each field.

[0093] Specifically, the specific encoding method is described in detail as follows:

[0094] 1. When the field type of the application data is String:

[0095] 1. If it is an empty string, the coding mode is the first string mode. At this time, the transmission mode does not need to be considered. When the coding mode is the first string mode, the coding method in the target message is: the value of the field type is 0x83, and the length of the field type is 1 byte. Here, the value of the field type is represented by 0x83, 0x83 is the custom coding value, 0x83 can represent that the field type is a string and is an empty string, and 0x83 represents both the field type and an attribute of the string.

[0096] 2. When it is a non-empty string and the transmission mode is the first transmission mode NONE, the encoding mode is the second string mode. When the encoding mode is the second string mode, the encoding method in the target message is as follows: the length of the field type is 1 byte, the value of the field type is 0x03, the length of the string length is 4 bytes, the value of the string length is the actual length of the string, the length of the string is the actual length of the string plus 1, and the value of the string is a null-terminated string.

[0097] Here, when encoding the string, it is necessary to encode the field type, the value of the field type, the string length, the value of the string length, the length of the string, and the value of the string. The length of the string and the string length are different. There is an information in the encoding information that limits the string length. For example, it is required to limit the string length of a certain field in the application data to only 4 bytes (specifying the length of the content to be filled).

[0098] For a null-terminated string, when parsing the message, it can be directly parsed without copying, which improves the parsing speed of the string.

[0099] 3. If the transmission mode is the second transmission mode FAST and the maximum actual length of the string is less than 21 bits, the encoding mode is the third string mode. Here, the attributes of the application data are further restricted. When the transmission mode is the second transmission mode FAST and the maximum actual length of the string is less than 21 bits, the encoding mode is determined to be the third string mode.

[0100] When the encoding mode is the third string mode, the encoding method in the target message is as follows: the length of the field type is 1 byte, the value of the field type is 0x43, the maximum length of the string length is 3 bytes, the value of the string length is the actual length of the string plus 1, the length of the string is the actual length of the string plus 1, and the value of the string is a null-terminated string. Here, the length of the string length can be 1 to 3 bytes.

[0101] 4. If the transmission mode is the second transmission mode FAST and the minimum actual length of the string is 21 bits, the encoding mode is the fourth string mode.

[0102] When the encoding mode is the fourth string mode, the encoding method in the target message is as follows: the length of the field type is 1 byte, the value of the field type is 0x03, the length of the string length is 4 bytes, the value of the string length is the actual length of the string plus 1, the length of the string is the actual length of the string plus 1, and the value of the string is a null-terminated string.

[0103] When the transmission mode is the second transmission mode, different coding modes can be adaptively selected according to the length of the string to perform encoding efficiently, so as to make reasonable use of resources.

[0104] 5. If the transmission mode is the third transmission mode MAX and the maximum actual length of the string is less than 21 bits, determine that the coding mode is the fifth string mode.

[0105] When the coding mode is the fifth string mode, the coding method in the target message is as follows: the length of the field type is 1 byte, the value of the field type is 0x43, the maximum length of the string length is 3 bytes, the value of the string length is the actual length of the string, the length of the string is the actual length of the string, and the value of the string is the string without carrying null. Here, the length of the string length can be 1 to 3 bytes.

[0106] 6. If the transmission mode is the third transmission mode MAX and the minimum actual length of the string is 21 bits, determine that the coding mode is the sixth string mode.

[0107] When the coding mode is the sixth string mode, the coding method in the target message is as follows: the length of the field type is 1 byte, the value is 0x03, the length of the string length is 4 bytes, the value of the string length is the actual length of the string, the length of the string is the actual length of the string, and the value of the string is the string without carrying null.

[0108] For example, the coding method is shown in Table 2: compact is the transmission mode.

[0109]

[0110]

[0111] Table 2

[0112] In this embodiment, encoding can be performed according to the coding methods that can be adopted according to different lengths of the string under the same transmission mode.

[0113] Second, when the field type of the application data is Int:

[0114] 1. When the field type of the application data is Int8, the coding mode is the Int8 mode.

[0115] When the coding mode is the Int8 mode, the coding method in the target message is as follows: the length of the field type is 1 byte, the value of the field type is 0x07, the length of the field value is 1 byte, and the field value is the actual value.

[0116] For example, the coding method is shown in Table 3:

[0117] Field Name Size Value Type 1 0x07 Value 1 Value

[0118] Table 3

[0119] 2. When the field type of the application data is Int16, the transmission mode is the first transmission mode NONE, and the minimum length of the field value is 7 bits, the encoding mode is the 16-bit integer first mode.

[0120] When the encoding mode is the 16-bit integer first mode, the encoding method in the target message is: the value of the field type is 0x09, the length of the field type is 1 byte, the length of the field value is 2 bytes, and the field value is the actual value.

[0121] 3. When the field type of the application data is Int16, the transmission mode is the fourth transmission mode not NONE, and the maximum length of the field value is less than 7 bits, the encoding mode is the 16-bit integer second mode.

[0122] When the encoding mode is the 16-bit integer second mode, the encoding method in the target message is: the value of the field type is 0x49, the length of the field type is 1 byte, the length of the field value is 1 byte, and the field value is the actual value.

[0123] For example, the encoding method is shown in Table 4:

[0124]

[0125] Table 4

[0126] 4. When the field type of the application data is Int32, the transmission mode is the first transmission mode NONE, and the minimum length of the field value is 21 bits, the encoding mode is the 32-bit integer first mode.

[0127] When the encoding mode is the 32-bit integer first mode, the encoding method in the target message is that the value of the field type is 0x0B, the length of the field type is 1 byte, the length of the field value is 4 bytes, and the field value is the actual value.

[0128] 5. When the field type of the application data is Int32, the transmission mode is the fourth transmission mode not NONE, and the maximum length of the field value is less than 21 bits, the encoding mode is the 32-bit integer second mode.

[0129] When the encoding mode is the 32-bit integer second mode, the encoding method in the target message is that the value of the field type is 0x4B, the length of the field type is 1 byte, the maximum length of the field value is 3 bytes, and the field value is the actual value. The length of the field value can be 1 to 3 bytes.

[0130] For example, the encoding method is shown in Table 5:

[0131]

[0132] Table 5

[0133] 6. When the field type of the application data is Int64, the transmission mode is the first transmission mode NONE, and the minimum length of the value of the field is 49 bits, the encoding mode is the 64-bit integer first mode.

[0134] When the encoding mode is the 64-bit integer first mode, the encoding method in the target message is that the value of the field type is 0x0D, the length is 1 byte, the length of the value of the field is 8 bytes, and the value is the actual value.

[0135] 7. When the field type of the application data is Int64, the transmission mode is the fourth transmission mode not NONE, and the maximum length of the value of the field is less than 49 bits, the encoding mode is the 64-bit integer second mode.

[0136] When the encoding mode is the 64-bit integer second mode, the encoding method in the target message is: the value of the field type is 0x4D, the length is 1 byte, the maximum length of the value of the field is 7 bytes, and the value of the field is the actual value. The length of the value of the field can be 1 to 7 bytes.

[0137] For example, the encoding method is shown in Table 6:

[0138]

[0139]

[0140] Table 6

[0141] III. When the field type of the application data is boolean:

[0142] 1. When the transmission mode is the first transmission mode NONE, the encoding mode is the boolean first mode.

[0143] When the encoding mode is the boolean first mode, the encoding method in the target message is: the value of the field type is 0x11, the length of the field type is 1 byte, the length of the value of the field is 4 bytes, and the value of the field is the actual value.

[0144] 2. When the transmission mode is the fourth transmission mode not NONE, the encoding mode is the boolean second mode.

[0145] When the encoding mode is the boolean second mode, the value of the field type in the target message is 0xD1 or 0x51, and the length of the field type is 1 byte.

[0146] Among them, 0xD1 and 0x51 are custom encoding values. 0xD1 can indicate that the type of the field is boolean and the value is true, and 0x51 can indicate that the type of the field is boolean and the value is false. Here, the custom encoding value can reduce the length and bytes of the encoded data and save space.

[0147] For example, the encoding method is shown in Table 7:

[0148]

[0149] Table 7

[0150] IV. When the field type of the application data is an object: The object here is a non-directly-readable object. Like a string, the size of a non-directly-readable object is variable. The non-directly-readable object can be OPAQUE, JAVA_OBJ, or.NET_OBJ. The non-directly-readable object first stores its size and then stores the data.

[0151] 1. When the transmission mode is the first transmission mode NONE or the minimum length of the object is 21, the encoding mode is the first object type mode.

[0152] When the encoding mode is the first object type mode, the encoding method in the target message is: the value of the field type is 0x16, 0x17, or 0x18, the length of the field type is 1 byte, the length of the field length is 4 bytes, the value of the field length is the length of the opaque, the value of the field is the actual value, and the length of the field is the actual length of the field.

[0153] 2. When the transmission mode is the fourth transmission mode not NONE and the maximum length of the object is less than 21 bits, the encoding mode is the second object type mode;

[0154] When the encoding mode is the second object type mode, the encoding method in the target message is: the value of the field type is 0x56, 0x57, or 0x58, the length of the field type is 1 byte, the maximum length of the field length is 3 bytes, the value of the field length is the length of the opaque, the value of the field is the actual value, and the length of the field is the actual length of the field.

[0155] Among them, 0x16 and 0x56 indicate that the field type is opaque, 0x17 and 0x57 indicate that the field type is java obj, and 0x18 and 0x58 indicate that the field type is dotnet obj.

[0156] For example, the encoding method is shown in Table 8:

[0157]

[0158]

[0159] Table 8

[0160] V. When the field type of the application data is a message, the variant data type also supports nesting messages, that is, one message can be stored in another message. In this embodiment, the message is encoded as follows:

[0161] 1. When the message is empty, the encoding mode is the first message mode.

[0162] When the encoding mode is the first message mode, the encoding method in the target message is: the value of the field type is 0x19, the length of the field type is 1 byte, the length of the message length is 4 bytes, and the value of the message length is 0.

[0163] 2. When the message is not empty, the encoding mode is the second message mode.

[0164] When the encoding mode is the second message mode, the encoding method in the target message is: the value of the field type is 0x19, the length of the field type is 1 byte, the length of the message length is 4 bytes, the value of the message length is the actual value of the message length, the value of the message content is the serialized message content, and the length of the message content is the actual value of the message length.

[0165] For example, the encoding method is shown in Table 9:

[0166]

[0167]

[0168] Table 9

[0169] In this step, for uncertain input data types, they can be expressed in a unified variant manner, expanding the application scenarios; the largest integer type data can be represented with the smallest number of transmission bytes. (Transmission optimization) The smallest number of transmission bytes is used during transmission, but a larger integer type is used during use. For example, it is defined as int64, but during actual transmission, it is varint. The null placeholder can be used, but it is not used for transmitting data and is used to split data, enabling fast data parsing. For data exceeding a certain value, a fixed length or variable length can be adaptively selected, and automatic optimization is performed according to the occupied space. For strings, an end marker can be added or not. After adding the end marker, there is no need to copy from the message and it can be directly parsed, improving the string parsing speed.

[0170] Step 23, the message sender transmits the target message to the message receiver.

[0171] In this embodiment, when transmitting application data of the same size, the data type and encapsulation method used use fewer bytes during transmission than the transmission method in the prior art.

[0172] Step 24, the message receiver receives the target message sent by the message sender.

[0173] Step 25, the message receiver parses the target message.

[0174] After obtaining the target message, the message receiver parses the target message. If parsing the custom encoding value, only need to parse the custom encoding value to directly obtain the field type and its value, only need to parse one kind of encoding, without parsing two kinds of encoding of type and value. If the value of the string is a string ending with null, when parsing the message, it can be directly parsed without copying, improving the parsing speed of the string.
