Therefore, under the unstable scene of the network, the packet type required by the request can be selected according to the loss condition of the data packet and the check packet, and the minimum data is requested in the secondary request, so that the delay of the message is reduced, and the pushing efficiency of the message is improved.

The data pushing method and the terminal are suitable for retransmitting the missing message under the condition of unstable network so as to improve the data pushing efficiency, and are described by a specific implementation mode:
example 1
Referring to fig. 1, a method for pushing data includes the steps of:
s1, receiving a data push request of a client, sending a data packet according to the data push request, and counting the packet loss ratio of long connection.
And sending a data packet according to the data push request, monitoring each heartbeat packet of the long connection and the sent data packet, and counting the packet loss ratio of each long connection in unit time.
Specifically, the heartbeat packets and packets sent by the message are monitored and counted. And counting the packet loss condition of each long connection in unit time. At this time, each long connection has its own independent timing task statistics thread, and its own packet loss ratio is counted.
S2, if the packet loss ratio is larger than a preset ratio, disassembling the data packet corresponding to the long connection, generating a check packet according to the data packet, and adding the check packet to the data packet to obtain a data push packet.
When the packet loss ratio does not reach the preset threshold, the processing is not performed, and when the packet loss ratio exceeds the preset threshold, corresponding information is written into the local cache, so that the subsequent program is convenient to use.
Specifically, assuming that the preset packet loss ratio is 20%, when the packet loss ratio within a unit time does not reach 20%, the data packet is still sent to the client. When the packet loss rate exceeds 20%, disassembling the transmitted data packet before transmitting the new message, generating a check packet by adopting a redundancy check algorithm, adding the check packet after the data packet, numbering according to the sequence of the data packet and the check packet to generate a data push packet, and transmitting the data push packet to the client.
And S3, sending the data push packet to the client by using the long connection, so that the client requests missing data of a packet type with a small missing quantity according to the missing quantity of the data packet and the check packet in the data push packet after receiving the data push packet.
After receiving the data push packet, the client judges whether a packet loss condition exists according to the number and the serial number of the data packet and the check packet in the data push packet, if not, ignores the check packet, if yes, reversely analyzes the transmitted data from the check packet when the check packet is complete, and when the check packet is missing, requests the missing data of the check packet if the missing number of the data packet is greater than the missing number of the check packet, and if the missing number of the data packet is less than or equal to the missing number of the check packet, requests the missing data of the data packet.
Specifically, in this embodiment, a whole batch of complete data push packets is of the packet type. I.e. normal packet type, and check packet type. Because each batch of data push packets are sequentially numbered, whether the packets are in shortage can be known according to the deficiency of the numbers. In practice, we can know the number of missing packets of normal data packets and the number of missing check packets. For example, a whole batch of data push packets is 30 in total, 20 data packets are represented as normal data packets, 10 data packets are check packets, when the network is unstable, the data packets are missing 4 data packets, the check packets are missing 8 data packets, and at the moment, only the missing data packets of 4 data packets need to be reissued again; if the number of missing data packets is 8 and the number of check packets is 2, the analysis of the complete data packets can be realized obviously by only supplementing 2 check packets. In a normal manner, all missing packets are sent in a full-complement manner, which causes additional useless packet transmission, causes IO resource occupation and increases time consumption.
Example two
Referring to fig. 2, a terminal 1 for data pushing includes a memory 2, a processor 3, and a computer program stored in the memory 2 and executable on the processor 3, wherein the processor 3 implements the steps of a method for data pushing according to the first embodiment when executing the computer program.
In summary, the method and the terminal for pushing data provided by the invention receive a data pushing request of a client, send a data packet based on the data pushing request and count a packet loss ratio, disassemble the data packet and generate a check packet when the packet loss ratio is greater than a preset ratio, obtain a data pushing packet according to the data packet and the check packet, and send the data pushing packet to the client; after receiving the data push packet, the client requests the missing data of the packet type with less missing quantity again according to the missing quantity of the data packet and the check packet. Therefore, under the unstable scene of the network, the packet type required by the request can be selected according to the loss condition of the data packet and the check packet, and the minimum data is requested in the secondary request, so that the delay of the message is reduced, and the pushing efficiency of the message is improved.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent changes made by the specification and drawings of the present invention, or direct or indirect application in the relevant art, are included in the scope of the present invention.
