In the current field of web application development, many enterprise-level web applications are implemented using the PHP language. Among them, the ThinkPHP framework is one of the pioneers in the development of domestic PHP frameworks. After years of development and improvement, it has become one of the most popular PHP frameworks in China. This article will build a complete enterprise-level Web application from scratch through the learning and practice of the ThinkPHP6 framework.
1. Installation and configuration
First, we need to install PHP and database (MySQL or other), as well as composer package manager in the local environment.
Secondly, download the latest version of the ThinkPHP6 framework and place the file in the specified working directory. Next, execute the "composer install" command in the command line window to install the dependent libraries and plug-ins required by the framework.
Then, we need to configure the project. First, configure the project's environment variables into the .env file, and rename the .env.example file to the .env file. Secondly, configure the database and set the database connection information in the /config/database.php file.
Finally, we need to run the "php think migrate:run" command in the root directory to create the database table and initial data.
2. Create controller and model
In the ThinkPHP6 framework, the controller (Controller) is used to process HTTP requests, and the main business logic processing is handled by the controller. Model is a class that obtains or stores data by operating the database.
In this example, we create a User controller and corresponding User model. Create the User.php file in the /app/controller folder and write the following code:
<?php namespace appcontroller; use thinkacadeDb; use thinkacadeRequest; class User { public function getAllUser() { $userList = Db::table('user')->select(); return json_encode($userList); } public function getUserById($id) { $user = Db::table('user')->where('id', $id)->find(); return json_encode($user); } public function addUser() { $data = Request::param(); Db::table('user')->insert($data); return 'Add Successfully'; } public function updateUser($id) { $data = Request::param(); Db::table('user')->where('id', $id)->update($data); return 'Update Successfully'; } public function deleteUser($id) { Db::table('user')->where('id', $id)->delete(); return 'Delete Successfully'; } }
Create the User.php file in the /app/model folder and write the following code:
<?php namespace appmodel; use thinkModel; class User extends Model { protected $table = 'user'; }
3. Create routing and views
In the ThinkPHP6 framework, routing (Route) is used to map URLs to corresponding controllers and methods, and view (View) is used to present the controller after processing. Data after business logic.
In this example, we created the following routes:
- GET /user: Get a list of all users and use the getAllUser method to process it.
- GET /user/:id: Get user information based on user ID, use getUserById method to process.
- POST /user: Add a new user, use the addUser method to process.
- PUT /user/:id: Update user information based on user ID, use updateUser method to process.
- DELETE /user/:id: Delete a user based on the user ID and use the deleteUser method.
In the /app/route.php file, write the following code:
<?php use thinkacadeRoute; Route::get('/user', 'User/getAllUser'); Route::get('/user/:id', 'User/getUserById'); Route::post('/user', 'User/addUser'); Route::put('/user/:id', 'User/updateUser'); Route::delete('/user/:id', 'User/deleteUser');
Next, create a User folder under the /app/view folder and place it in the folder Create view files such as index.html, edit.html, add.html and so on.
In the index.html file, we can list all user lists. In the edit.html and add.html files, we can edit and add user information.
Finally, write the corresponding view rendering method in the controller. For example, in the User controller, we can write the following code:
public function all() { return view('index')->assign('userList', Db::table('user')->select()); } public function edit($id) { return view('edit')->assign('user', Db::table('user')->where('id', $id)->find()); } public function add() { return view('add'); }
4. Implement user authentication
In enterprise-level Web applications, user authentication is a very important function. Within the ThinkPHP6 framework, we can implement simple and flexible user authentication through the Auth component.
First, we need to perform authentication-related configurations in the /config/auth.php file.
Next, we can use the login, logout, check and other methods provided by the Auth component in the controller to develop the user authentication function. For example, in the User controller, we can write the following code:
<?php namespace appcontroller; use appmodelUser as UserModel; use thinkacadeDb; use thinkacadeRequest; use thinkacadeSession; use thinkacadeView; use thinkuthAuth; class User { public function login() { if (Request::isPost()) { $data = Request::param(); if (Auth::attempt(['username' => $data['username'], 'password' => $data['password']])) { Session::flash('success', 'Login successfully.'); return redirect('/index'); } else { Session::flash('error', 'Login failed.'); return view('login'); } } else { return view('login'); } } public function register() { if (Request::isPost()) { $data = Request::param(); $userModel = new UserModel(); $userModel->save($data); return redirect('/login'); } else { return view('register'); } } public function logout() { Auth::logout(); Session::flash('success', 'Logout successfully.'); return redirect('/login'); } public function check() { $user = Auth::user(); if (!$user) { Session::flash('error', 'You are not logged in.'); return redirect('/login'); } return $user; } }
5. Implement the API interface
In enterprise-level web applications, the API interface is a very important function. Within the ThinkPHP6 framework, we can develop API interfaces to meet the data requests from the calling end.
In this example, we created the following API interfaces:
- GET /api/user: Get a list of all users, use the getAllUser method to process.
- GET /api/user/:id: Get user information based on user ID, use getUserById method to process.
- POST /api/user: Add a new user, use the addUser method to process.
- PUT /api/user/:id: Update user information based on user ID, use updateUser method to process.
- DELETE /api/user/:id: Delete a user based on the user ID and use the deleteUser method.
In the controller, we need to handle the API interface version, request type, request parameters, response format and other related content.
For example, in the User controller, we can write the following code:
<?php namespace appcontroller; use appmodelUser as UserModel; use thinkacadeDb; use thinkacadeRequest; class User { // ... public function getAllUser() { $userList = Db::table('user')->select(); return json($userList); } public function getUserById($id) { $user = Db::table('user')->where('id', $id)->find(); return json($user); } public function addUser() { $data = Request::param(); Db::table('user')->insert($data); return 'Add Successfully'; } public function updateUser($id) { $data = Request::param(); Db::table('user')->where('id', $id)->update($data); return 'Update Successfully'; } public function deleteUser($id) { Db::table('user')->where('id', $id)->delete(); return 'Delete Successfully'; } }
6. Deploy Web applications
After we develop the enterprise-level Web application, we need Deploy it to the server for users to access. During the specific deployment process, we need to pay attention to the following points:
- Security: During the deployment process, we need to ensure the security of the application. For example, application security is ensured by encrypting sensitive data and filtering out malicious requests.
- Performance optimization: During the deployment process, we need to perform performance optimization on the application. For example, use caching technology to speed up page access, enable Gzip compression to reduce the amount of data transmission, etc. to improve application performance.
- Monitoring and maintenance: During the deployment process, we need to establish a complete monitoring and maintenance system. For example, use an independent log server to store log information, use monitoring tools to monitor the running status of the application in real time, etc. to ensure the effective operation of the application.
4. Summary
Through the above steps, we successfully used the ThinkPHP6 framework to create a complete enterprise-level Web application from scratch, and learned the corresponding knowledge and Skill. In future development work, we can flexibly use these technologies according to specific situations to develop better Web applications.
