Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of an embodiment of a method for receiving server push data according to the present invention, as shown in fig. 1, including: s101, receiving the push data of the server through any one of a plurality of receiving ways, wherein the push data of the receiving server of each receiving way is the same; s102, screening the finally received push data from the push data of each receiving path receiving server.
Specifically, each receiving path receives the push data of the server once, and the time for receiving the push data of the server by each receiving path is the same or different.
Further, in step S102, the finally received push data is screened from the push data of each receiving path receiving server, where the finally received push data may be the receiving path that receives the push data first, the receiving path that receives the push data last, and the like.
According to the method for receiving the server push data, the push data of the server are received through the multiple receiving ways, the data loss rate can be reduced, and the reliability of data acquisition can be ensured by screening the finally received push data from the push data of the server received through each receiving way.
Based on the above embodiment, the receiving, by any of the multiple receiving paths, the pushed data of the server further includes: a plurality of reception paths are established with the server, the plurality of reception paths comprising a number of long connections and/or a number of polling services.
Specifically, the plurality of receiving paths include a plurality of long connections and/or a plurality of polling services, that is, the plurality of receiving paths include a plurality of long connections and do not include a polling service, or the plurality of receiving paths include a plurality of polling services and do not include a long connection, or the plurality of receiving paths include a plurality of long connections and include a plurality of polling services.
Further, several of the embodiments of the present invention include one or more. A long connection means that multiple packets can be sent continuously over one connection, and during the connection hold period, if no packet is sent, a link check packet needs to be sent in both directions. Long connections are often used for frequent, point-to-point communications, and the number of connections cannot be too great. Each TCP connection needs three-step handshake, which requires time, and if each operation is a short connection, the processing speed is reduced greatly if the operation is repeated, so that each operation is not disconnected after the operation is completed, and the data packet is OK when the next processing is performed, and the TCP connection does not need to be established. For example: the connection of the database uses a long connection, if the communication is frequent with a short connection, the socket error is caused, and the frequent socket creation is also a waste of resources.
Polling (Polling) is a way for a CPU to decide how to provide services to peripheral devices, and is also called Programmed I/O. The polling method is that CPU sends out inquiry in certain time to inquire each peripheral equipment whether it needs its service, if so, the peripheral equipment gives service, and after the service is over, the peripheral equipment asks the next peripheral equipment, and then the process is repeated.
