Problems solved by technology

However, RPC depends to some extent on the operating system and application development tools, and cannot communicate across platforms; in addition, RPC is passive communication and cannot actively notify communication. This method requires different development tools or platforms for different manufacturers or Situations that require two-way communication do not work well
[0010] The inventor found in the process of realizing the present invention that none of the above methods can reliably transmit data with sequence and structure information, and there is still no feasible solution to this problem

Embodiment 1

[0038] This embodiment provides a method for sending data, see figure 1 , which is a flowchart of a method for sending data provided in this embodiment, the method includes:

[0039] Step S102: Determine the data structure corresponding to the data to be sent;

[0040] In this embodiment, the corresponding data structure is defined in advance according to the type of data to be sent, and the length of data in different data structures may be different; when data is to be sent, the data structure corresponding to the data to be sent currently is determined according to the definition;

[0041] Step S104: Determine the command type and data length according to the above data structure;

[0042] Step S106: When sending the data in the above data structure for the first time, store the current data according to the specified data packet format, and send the current data in TCP mode;

[0043] Wherein, the specified data packet format is shown in Table 1, including command header ...

Embodiment 2

[0050] This embodiment also provides a method for processing received data, which is based on the method for sending data provided in Embodiment 1, see figure 2 , which is a flowchart of a method for processing received data provided in this embodiment, the method includes:

[0051] Step 202: cache the data in the received data packet into a buffer; the data packet includes a command header, wherein the command header carries a command type and a data length;

[0052] If the received data packet does not include the command packet header, directly cache it into the buffer;

[0053]Step 204: Packetize the data in the buffer according to the above data length;

[0054] Since the application program does not set the TCP_NODELAY attribute for TCP, when transmitting data in TCP mode, in order to improve the transmission efficiency, the sender often needs to collect enough data before sending a packet of data. If the data sent several times in a row is very little, Usually TCP wi...

Embodiment 3

[0065] This embodiment provides a method for sending data, which is the same as that in Embodiment 1 figure 1 The difference of the shown methods is that in this embodiment, when data is sent, the command header also carries a command header flag, which is used to indicate whether the receiver caches the currently sent data.

[0066] When the data that needs to be sent is ordinary data, for example, when what needs to be sent is continuous stream data without structure (such as: file), the receiver does not need to subpackage the data, so it does not need to process the data After receiving these data, they can be processed according to the usual processing method. For this reason, this embodiment carries a command header flag in the command packet header to indicate whether the receiver caches the current data. For example, the pre-agreed command The header flag is 1, which means that the current data needs to be cached, and the pre-agreed command header flag is 0, which mean...

Abstract

The invention provides a method and a device for transmitting data, and a process method and a device for receiving data, belonging to the field of communication. The method for transmitting the data comprises the steps of: ensuring data structure corresponding to data to be transmitted, ensuring command type and data length, memorizing current data according to the appointed mode of an data packet when firstly transiting the data in the data structure, and transmitting the current data by the means of TCP, wherein the appointed mode of the data packet comprises an command packet head and the current data, and the command packet head carries the command type and the data length. By adopting the appointed mode of the data packet to transmit the data, the invention leads the receiving party to be capable of correctly packaging the received data packet based on the length, and reliably transmitting the data with sequence and structural information.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method and device for sending data, and a method and device for processing received data. Background technique [0002] In the process of application development, it is often necessary to reliably send data from one application to another, and the transmitted data is generally sequenced and structured (fixed or indeterminate) data, and the receiver usually needs to check these The data is processed in packets. [0003] The relevant data transmission technologies include the following methods: [0004] 1) Use UDP (User Datagram Protocol, User Datagram Protocol) for data network transmission [0005] The UDP protocol is a datagram mode. Data is sent one by one through data packets. UDP is used for data network transmission. The data packets are likely to be lost, or the order of the data packets will change, so the UDP protocol is not suitable for the sequence. And d...
