Description

Technical Field

[0001] The present application relates to the technical field of WEB front-end development, for example, to a method and storage medium for implementing multi-server SOL. Background Art

[0002] Vue is a JavaScript MVVM library that embodies the best practices of the MVVM architecture. It's a progressive framework for building user interfaces. Focusing on the ViewModel in MVVM, it not only enables two-way data binding but is also a relatively lightweight JS library with a concise API.

[0003] Xterm is a terminal emulator based on web technologies. It is a front-end terminal component written in TypeScript. It can create an interactive terminal interface in the browser to implement a command-line terminal application. Xterm provides a powerful way to integrate terminal functionality into web applications, allowing users to interact with remote servers or local command lines in the browser.

[0004] WebSocket is a network communication protocol that enables arbitrary, two-way data transmission between web browsers and servers, enabling real-time, two-way communication between browsers. Implemented over TCP, the WebSocket protocol includes an initial handshake and subsequent, multiple, two-way data frame transmissions. Its purpose is to enable frequent two-way communication between WebSocket applications and WebSocket servers by enabling the server to avoid opening multiple HTTP connections, thereby conserving resources and improving efficiency and resource utilization.

[0005] SOL, short for Serial over LAN, is a technology for controlling a computer remotely via a network connection. It uses a serial communication port to transmit control information and management commands, transmitting this information to the remote computer over the network. This allows for remote computer management without physical contact, requiring only a network connection.

[0006] However, existing technical solutions cannot realize the SOL function for multiple servers.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application. Summary of the Invention

[0008] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0013] In some embodiments, a new index.js file is created to store page routes, including:

[0014] Based on index.js as the entry point for each menu-related page routing, specify the location of the main page;

[0015] Import SerialOverLan.vue, name it SerialOverLan, and export it as the default page.

[0023] Introduce the Terminal corresponding to the Xterm component;

[0024] According to the referenced Terminal, set the corresponding terminal according to the number of servers, and define ref as panel1~n;

[0025] Write the setData method to receive the parameters and data passed to the tab content page and obtain the corresponding IP address;

[0026] Write the openTerminal method, get the return value based on the IP address and assign it to attachAddon, then loadAddon the value in Terminal, bind it to the corresponding ref, and open it.

[0061] It should be further explained that the new SerialOverLan.vue is created to store multiple page tabs and provide reserved space for Terminal, which can realize the main page for the entire SOL function.

[0062] In some embodiments, the defined data are parameters and data corresponding to the subcomponents.

[0063] In some embodiments, a new SerialOverLanConsole.vue is created to implement the interactive command line functionality of SOL, including:

[0064] Introduce the Terminal corresponding to the Xterm component;

[0065] According to the referenced Terminal, set the corresponding terminal according to the number of servers, and define ref as panel1~n;

[0066] Write the setData method to receive the parameters and data passed to the tab content page and obtain the corresponding IP address;

[0070] In some embodiments, Figure 1 The method may further include:

[0071] When the page is closed or switched to another module page, the current Terminal is disconnected and closed.

[0072] In a specific example, a project dynamically generates four different tab pages based on four different modules of the whole machine, and opens the SOL interactive interface of the corresponding module in each tab page.

[0073] The first step is to create a new index.js file to store page routing;

[0074] Step 1: index.js serves as the entry point for each menu-related page routing, specifying the location of the main page;

[0075] Step 2: Import SerialOverLan.vue, name it SerialOverLan, and export it as the default page.

[0076] Step 2: Create a new SerialOverLan.vue file: This is the main page for the entire SOL function.

[0084] Step 3: Write the setData method to receive the parameters and data passed to the tab content page in step 2 and obtain the corresponding IP address;

[0085] Step 4: Write the openTerminal method, call the websocket interface {new WebSocket(`wss: / ${xx_IP} / console0`)} according to the IP address, get the return value and assign it to attachAddon, then loadAddon the value in Terminal, bind it to the corresponding ref, and open it.

[0086] Step 5: Finally, when the page is closed or switched to another module page, disconnect and close the current Terminal.

[0087] The implementation method of multi-server SOL in the present disclosure is implemented by using Xterm and Vue together, and Xterm and Vue are used to provide an interactive experience similar to that of a local terminal, and WebSocket-based applications are converted into interactive command line tools through Xterm. The present disclosure can realize comprehensive remote monitoring and management of remote computers, including remote shutdown, restart, firmware update and other operations, thereby reducing the need for physical contact. The output print information of the serial communication port (Serial Port) on the remote computer can be monitored to timely discover, troubleshoot and solve problems.
