How to use WebMan technology to build a powerful website

With the rapid development of the Internet, every enterprise urgently needs a powerful website to display its products and services. WebMan technology is a tool that helps developers build efficient, secure and easy-to-maintain websites. This article will introduce how to use WebMan technology to build a powerful website and provide some code samples for readers' reference.

First of all, we need to understand the principles and advantages of WebMan technology. During the development process, WebMan adopted a modular design idea to decompose the website's functions into multiple independent modules, each of which has independent functions and data structures. This design makes website maintenance and updates more convenient, while also improving website performance and security.

Before we start building the website, we need to install the development environment of WebMan technology. WebMan uses PHP as the backend language and requires a database to store the website's data. We can choose to use popular databases such as MySQL and PostgreSQL.

Once the development environment is set up, we can start building the website. First, we need to create a database and create corresponding data tables in the database to store the website data. For example, we can create a users table to store user information. The following is a simple sample code:

CREATE TABLE users (
  id INT AUTO_INCREMENT PRIMARY KEY,
  username VARCHAR(50) NOT NULL,
  password VARCHAR(255) NOT NULL
);

Next, we need to write the backend code to handle the user's request and return the corresponding data. The following is an example of PHP code using WebMan technology:

<?php
require_once 'webman.php';

webman()->route([
  'GET /users' => function() {
    $users = db()->select('users');
    return json($users);
  },
  
  'POST /users' => function() {
    $data = request()->post();
    $user = db()->insert('users', $data);
    return json($user);
  },
  
  'GET /users/{id}' => function($id) {
    $user = db()->get('users', $id);
    if (!$user) {
      return text('User not found', 404);
    }
    return json($user);
  }
]);

webman()->start();

In the above code, we have defined three routes to handle user requests. The first route handles GET requests and returns information about all users; the second route handles POST requests and inserts user information into the database; and the third route handles GET requests and returns information about specific users. This is a simple example, you can extend and modify these routes according to your actual needs.

Finally, we need to write front-end code to implement the user interface and interaction. Front-end pages can be developed using HTML, CSS, and JavaScript. The following is a simple front-end code example using Vue.js:

<!DOCTYPE html>
<html>
<head>
  <title>WebMan Example</title>
  <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
  <div id="app">
    <ul>
      <li v-for="user in users">{{ user.username }}</li>
    </ul>
    <form @submit.prevent="addUser">
      <input v-model="username" placeholder="Username">
      <input v-model="password" placeholder="Password">
      <button type="submit">Add User</button>
    </form>
  </div>
  
  <script>
    new Vue({
      el: '#app',
      
      data: {
        users: [],
        username: '',
        password: ''
      },
      
      mounted() {
        this.loadUsers();
      },
      
      methods: {
        loadUsers() {
          fetch('/users')
            .then(response => response.json())
            .then(users => this.users = users);
        },
        
        addUser() {
          fetch('/users', {
            method: 'POST',
            headers: {
              'Content-Type': 'application/json'
            },
            body: JSON.stringify({
              username: this.username,
              password: this.password
            })
          })
            .then(response => response.json())
            .then(user => {
              this.users.push(user);
              this.username = '';
              this.password = '';
            });
        }
      }
    });
  </script>
</body>
</html>

In the above code, we use Vue.js to implement a simple user interface and interaction. By using the fetch API, we can send HTTP requests to obtain the user's information, or submit the user's information to the server.

The above are the basic steps and code examples for using WebMan technology to build a powerful website. I hope this article can help readers understand and apply WebMan technology and achieve success in the development process. May your website gain more users and success!
