Description

Data processing method and device of hypertext transfer protocol and server

Technical Field

The present application relates to the field of network transmission, and in particular, to a data processing method and apparatus for a hypertext transfer protocol, and a server.

Background

The hypertext transfer protocol involves several links as follows:

HTTP short links are not persistent links: short connections are used by default in HTTP/1.0. That is, the client and the server establish a connection every time they perform an HTTP operation, and the connection is interrupted when the task ends. When a certain HTML or other types of WEB pages accessed by the client browser contain other WEB resources, the browser can reestablish an HTTP session when encountering such a WEB resource.

HTTP long link or persistent link: from HTTP/1.1, a long connection is used by default to maintain connection characteristics. In the case of using a long connection, after a web page is opened, the TCP connection for transmitting HTTP data between the client and the server is not closed, and the client continues to use the established connection when accessing the server again. Keep-Alive does not Keep the connection permanently, it has a hold time, which can be set in different server software. Achieving long connections requires both the client and the server to support long connections.

Furthermore, the HTTP protocol is stateless, which means that the protocol has no memory capability for transactions and the server does not know what the client is. That is, there is no connection between opening a web page on one server and last opening a web page on that server. That is, HTTP is a stateless short link or long link oriented protocol.

Because the browsing terminal is a web browser, for the sake of generality, a plug-in cannot be installed, and the browsing terminal can only operate through the standard HTTP protocol of the browser. The inventor finds that the operation command cannot continuously reach the acquisition terminal software program in the intranet for a long time, and the configuration of the acquisition terminal software program in the intranet cannot be completed directly through the HTTP protocol. That is, the acquisition-side software program cannot be located through the web browser.

Aiming at the problem that the acquisition end software program cannot be positioned through a web browser in the related art, an effective solution is not provided at present.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, the method includes steps S102 to S108 as follows:

step S102, synchronizing a first transmission command identifier of a client;

the client reports the unique MAC network card address to the network station end, and stores the unique MAC network card address into the MySQL database as an interactive command identifier. The synchronous mode is that the MAC reporting address is used for positioning and forwarding. The client may be a software application on the harvesting side.

Step S104, establishing long link between the client and the transfer server;

Before the first transmission command forwarded from the client is obtained, the first transmission command is firstly received through a transit server port and then forwarded.

Step S108, receiving the first transmission command forwarded by the transit server through the web browser.

The web browser may receive the first transmission command forwarded from the transit server. The original browser forward HTTP request process is kept unchanged, but when a website server processes an HTTP request, a process of forwarding the obtained request is added, a forwarding object is a TCP long link, a waiting command processing state is kept for a long time all the time, and the forwarding object looks like a reverse long link when viewed from a browser end which sends a command.

and the PHP extension plug-in waits for the positioning and forwarding of the target address and the transmission of the positioning characteristic parameters within a timeout range.

The PHP extension plug-in can wait for the processing result of the forwarding command within the timeout range and forward the result back to the PHP extension plug-in.

The obtaining of the first transmission command forwarded from the client comprises:

preferably, the webpage browser in the PHP extension plug-in triggers the PHP extension command to forward the first transmission command in the JSON string format forwarded from the client through the PHP website. The data finally received by the PHP extension plug-in is always a JSON character string, so that the PHP extension plug-in is convenient to process.

In particular, the dedicated interface may employ PHP extensions. PHP extension employs a Hypertext Preprocessor (english name: Hypertext Preprocessor, abbreviation: PHP) which is a common open source scripting language. The interaction between the PHP and the WEB page is an important means for realizing the interaction between the PHP website and the user. Two methods for interacting with the WEB page are provided in the PHP, one is to submit data through a WEB form, and the other is to transmit through a URL parameter.

For example, WEB page interaction information via a hypertext preprocessor at a user terminal is received through a PHP interface.
