The invention sends partial data to the request of the client through the set lazy loading technology, judges whether the client continuously requests, if the client continuously requests to send the data again, if the client does not request to close the communication channel between the client and the server, the occupancy rate of the server is effectively reduced, the server caches the data requested by the client, and when the client requests the same data again in the same time period, the server does not need to search and screen the same data again, and the operation efficiency of the server is improved.
Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a communication method for network data.
Background
Data communication is a new way of communication that results from the combination of communication technology and computer technology. The transmission channel is necessary for transmitting information between two places, and according to the difference of transmission media, the wired data communication and the wireless data communication are divided, but they are all connected with the data terminal and the computer by the transmission channel, so that the data terminals at different places can realize the sharing of software, hardware and information resources.
In the existing data communication process, a server generally directly sends all related data of data requested by a client, so that the search time of a client is increased, the running time of the server is increased, meanwhile, a cache mechanism is not set for the data requested by the client by the existing server, and when the client requests the same data in a short time, the server is required to inquire and screen the data again, so that the running efficiency of the service is influenced.
Disclosure of Invention
The present invention is directed to a method for communicating network data, which solves the above problems of the related art.
In order to achieve the purpose, the invention provides the following technical scheme: a communication method for network data, comprising the steps of:
s1: a client sends a data request to a server;
a 1: the client side edits and then sends the sent request through a computer, and the computer converts the data to be searched into a binary byte code file and sends the request through an application layer FTP protocol;
a 2: the transmitted request is transmitted through a transmission layer TCP protocol and a network layer IP protocol;
a 3: the transmitted request establishes a communication channel with a remote server through an Ethernet driver of a link layer;
s2: the server receives the request and processes the sent request;
b 1: when the server receives request data of the client, converting the byte code file into a decimal file, analyzing and processing the data, and determining the request data of the client;
b 2: the server searches the requested data comprehensively, screens the searched data and packages the screened data;
b 3: the server caches the data processed by the package;
s3: the server and the client establish a bidirectional communication channel and return a corresponding status code; 200: the server has successfully processed the request, 202: request received by the server, but not yet processed, 203: the server has successfully processed the request, but the information returned is from another source; 204: the server has successfully processed the request, but has not returned any content; 400 request error, server does not understand request syntax; 404 does not find the request data, 406 cannot request the authorization information;
s4: the server returns the data requested by the client;
c 1: converting the data of the package into a plurality of package files in a classified manner, and converting the plurality of package files into binary files;
c 2: the server transmits the converted binary file through a lazy loading technology and transmits the converted binary file to a corresponding client through a TCP/IP protocol;
c 3: the client analyzes the received data file to determine the security of the transmitted file;
c 4: the confirmed file passes through a firewall of the client and is converted into a decimal file through an FTP protocol, and the return of the request data is completed;
preferably, the lazy loading technique sends local data to a data request sent by a client, determines that the client continues to request, and sends the requested data again if the request is not repeated, and closes a communication channel between the server and the client.
Preferably, the server establishes a bidirectional channel connection with the client, and d 1: the client sends a SYN packet to the server, and the SYN packet is j and enters a SYN-SENT state to wait for the server to confirm; d 2: the server receives the SYN packet, must confirm the SYN (ACK ═ j +1) of the customer, send a SYN packet (SYN ═ k) at the same time (SYN ═ k), namely SYN + ACK packet, the server enters SYN _ RECV state at this moment; d 3: and the client receives the SYN + ACK packet of the server and sends an acknowledgement packet ACK (ACK being k +1) to the server, and after the packet is sent, the client and the server enter an ESTABLISHED state to complete the bidirectional channel between the client and the server.
Preferably, the caching process caches data requested by the client, and directly sends the cached data to the client when the client requests again at a set time.
The invention has the technical effects and advantages that: the method has the advantages that partial data are sent to the request of the client through the existing lazy loading technology, whether the client continues to request or not is judged, if the client continues to request to send the data again, if the communication channel between the client and the server is not required to be closed, the occupancy rate of the server is effectively reduced, the server caches the data requested by the client, and when the client requests the same data again in the same time period, the server does not need to search and screen the same data again, and the operating efficiency of the server is improved.

Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
The present invention provides a method of communicating network data as shown in figures 1-2,
s1: a client sends a data request to a server;
a 1: the client side edits and then sends the sent request through a computer, and the computer converts the data to be searched into a binary byte code file and sends the request through an application layer FTP protocol;
a 2: the transmitted request is transmitted through a transmission layer TCP protocol and a network layer IP protocol;
a 3: the transmitted request establishes a communication channel with a remote server through an Ethernet driver of a link layer;
s2: the server receives the request and processes the sent request;
when the server receives request data of the client, converting the byte code file into a decimal file, analyzing and processing the data to determine the request data of the client, comprehensively searching the request data by the server, screening the searched data, packaging the screened data, caching the packaged data by the server, caching the data requested by the client, and directly sending the data of the cache to the client when the client requests again at set time;
