Abstract

The invention provides a method for automatic connection between a client and a server. The method provides at least one HTTP server and at least one HTTP client. The administrator can manage the HTTP server through the browser page of the HTTP client. The method comprises the steps: the HTTP client sends a reboot command to the HTTP server; the browser page displays the waiting time; counting down the waiting time; judging whether the countdown is zero; if the countdown is not zero, then continue the countdown; Zero, the HTTP client automatically connects with the HTTP server. The invention also provides a system for automatic connection between the client and the server. The present invention can provide convenient operation and clearer information to the manager, so that the manager can clearly know the waiting time for starting the HTTP server.

Description

System and method for automatic connection between client and server

【Technical field】

The invention relates to a system and method for connecting a client and a server.

【Background technique】

The communication between the HTTP client (HTTP Client) and the HTTP server (HTTP Server) is not always connected, and it is a one-way communication mode, that is, when the client sends a request (Request) to the server , the server will return a Response to the client after receiving it. The server cannot actively send a Request to the client. Therefore, when the server has information to notify the client, it must wait until the client sends a request next time before the client can obtain this information.

In the above communication mode, users often encounter such problems:

When HTTP is used as the protocol (Protocol) of the management system (such systems as NAS, SAN, DAS, NAT, etc.), the above-mentioned system can be similar to a general HTTP server, and the administrator uses the HTTP client (HTTP Client) browser to manage such systems. For example, for the above-mentioned NAS (Network Attached Storage, network attached storage device) system, it is a storage device attached to the network, which uses the HTTP protocol commonly used in the network to allocate storage space to servers or workstations on the network, and Data file sharing patterns appear on the Internet. As far as network applications are concerned, NAS is similar to a general HTTP server, and it is like a large file server to HTTP clients. After the administrator sends a restart command to the HTTP server through the browser on the HTTP client, he loses contact with the HTTP server and does not know when the HTTP server will complete the startup. Because the HTTP server cannot notify the administrator through the HTTP protocol after restarting. All the administrator can do now is to keep tapping the mouse to make the browser try to connect.

Therefore, it is necessary to provide a more convenient operation and clearer information to the administrator, so that the administrator can clearly know the waiting time for booting, without having to keep tapping the mouse to make the browser try to connect to the HTTP server .

【Content of invention】

The purpose of the present invention is to provide a system for automatic connection between the client and the server, which can provide more convenient operation and clearer information to the manager, so that he can clearly know the waiting time for the server to start.

Another object of the present invention is to provide a method for automatic connection between the client and the server, which can provide more convenient operation and clearer information to the administrator, so that he can clearly know the waiting time for the server to start.

To achieve the above purpose, the present invention discloses a system for automatic connection between client and server. The system includes at least one HTTP server and at least one HTTP client. The administrator can manage the HTTP server through the browser page of the HTTP client. Described HTTP client comprises: an instruction sending module, is used for HTTP client to send the instruction of rebooting to HTTP server by browser to restart HTTP server; A display module, is used for after HTTP client sends restarting instruction, in Display waiting time M seconds on the browser page of HTTP client; A countdown module, be used for when displaying waiting time, start countdown; Whether the timer expires. The waiting time M seconds is greater than the HTTP server startup time N seconds.

The present invention also discloses a method for automatic connection between a client and a server. The method provides at least one HTTP server and at least one HTTP client. The administrator can manage the HTTP server through the browser page of the HTTP client. The method comprises the steps: (a) the HTTP client sends a restart command to the HTTP server; (b) the HTTP client browser page displays the time M seconds to wait, and the time M seconds to wait is greater than the HTTP server startup time The required time is N seconds; (c) count down the waiting time; (d) judge whether M is zero; (e) if M is not zero, return to step c; (f) if M is zero, the HTTP client Automatically connect with HTTP server.

The present invention can provide convenient operation and clearer information to the administrator, so that the administrator can clearly know the waiting time for the HTTP server to start up, and there is no need to continuously tap the mouse to let the browser try to connect when the HTTP server is restarted. Wire.

【Description of drawings】

Fig. 2 is a functional block diagram of the HTTP client of the present invention.

Fig. 3 is a flow chart of the method for automatic connection between the client and the server of the present invention.

【Detailed ways】

Referring to FIG. 1 , it is a schematic diagram of the implementation hardware environment of the automatic connection system between the client and the server of the present invention. The system includes at least one HTTP client (HTTP Client) 10 and at least one HTTP server (HTTP Server) 20 supporting JavaScript. Wherein, the HTTP client 10 is used to provide a browser page for the administrator to manage the HTTP server 20, and the HTTP server 20 may be a file server. After the HTTP client 10 sends a request signal 101 to the HTTP server 20 , the HTTP server 20 returns a response signal 202 to the HTTP client 10 according to the request signal 101 .

Referring to Fig. 2, it is a functional block diagram of the HTTP client of the present invention. The HTTP client 10 includes four functional modules, namely an instruction sending module 102 , a display module 103 , a countdown module 104 and a judging module 105 . Wherein instruction sending module 102 is used for HTTP client 10 to send the instruction of restarting to HTTP server 20 by browser to restart HTTP server; Display waiting time M seconds on the browser page, this waiting time M second is greater than the time N second of restarting of HTTP server 20; Countdown module 104 is used for when displaying waiting time, starts countdown; Judgment module 105 is used for countdown At the same time, it is judged whether the waiting time M is equal to zero, that is, whether the countdown is over.

Referring to FIG. 3 , it is a flowchart of the automatic connection method between the client and the server of the present invention. Assume that the time required for the startup of the HTTP server 20 is N seconds. First, the instruction sending module 102 sends a restart instruction to the HTTP server 20, and the HTTP server 20 executes a restart action (step S300). The display module 103 starts to display the waiting time M seconds on the interface of the HTTP client 10, wherein M seconds is greater than N seconds (step S302). The countdown module 104 starts countdown at the same time (step S304). The judging module 105 judges whether the waiting time M is equal to zero (step S306). If M is not equal to zero, then return to step S304; if M is equal to zero, it indicates that the waiting time ends, and the HTTP client 10 automatically connects with the HTTP server 20 (step S308).
