NodeJs mobile phone access to local server case analysis
This time I will bring you a case analysis of NodeJs mobile phone accessing the local server. What are the precautions for NodeJs mobile phone to access the local server. The following is a practical case, let's take a look.
As a front-end engineer who doesn't understand the background, it is a very good choice to use node.js to build a server. Let’s build a simple server:
var app=require("express")(); //接收来自用户的任何请求 app.use(function(req,res){ res.write("The response from server"); res.end(); });
This IP address, the poster always thought that specifying the IP address here means that others can access your server by entering this IP address, but this is not the case. If you specify an IP address, it means that only the IP address can be accessed. So, generally, if anyone has access, don't write.
//port写端口号,ip写ip地址, app.listen(port,ip,function(err){ if(err){ console.error(err); }else { console.info("服务器起动成功.."); } });
1. Make sure that your computer and mobile phone are in the same network segment, that is, they are both in the same LAN. This can be achieved by connecting both the mobile phone and the computer to a wireless network;
2 . Enter ipconfig in the computer cmd to view the IP address of the current wireless network, and then copy the IP address to the monitored IP address. When accessing on the mobile phone, directly enter the IP address and port number; for example: 192.1.1.103
3 . Make sure that the port number that the server you built is listening is turned on on the computer (in order to prevent conflicts, it is not recommended to use port 80, more than 6000 ports, just write it casually, for example: 6868). Please refer to Baidu for details on how to turn it on, here No explanation;
If you still can't access it after turning it on, then there is only one ultimate method, turn off the firewall. After everything is set up successfully, enter 192.1.1.103:6868 in the mobile browser to access it successfully.
I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.
