With the continuous development of Internet technology, front-end and back-end separation has become an increasingly popular development model. Front-end and back-end separation physically separates the front-end and the back-end. The front-end is responsible for page display, and the back-end is responsible for data processing and logical operations. This model can effectively improve development efficiency and application performance, while also reducing development costs.

ThinkPHP is a very popular PHP framework. It provides a wealth of development tools and framework functions that can help us quickly build Web applications. In this article, we will introduce how to use ThinkPHP6 to achieve front-end and back-end separation.

1. Preparation work

Before starting to use ThinkPHP6 for front-end and back-end separation development, we need to do some preparation work. First, we need to prepare the back-end development environment, including PHP environment, Composer dependency management tool and ThinkPHP6 framework. Secondly, we need to prepare the front-end development environment, including Node.js environment, Vue.js framework and some common front-end tools.

2. Create a ThinkPHP6 project

Creating a ThinkPHP6 project is very simple, just use the Composer command:

composer create-project topthink/think myapp

Copy after login

After executing the above command, it will be generated in the current directory A ThinkPHP6 project called myapp.

3. Configure routing

When using ThinkPHP6 to achieve front-end and back-end separation development, we need to use routing to map front-end requests to back-end handlers. In ThinkPHP6, the routing configuration file is route/route.php, and we can configure routing rules in this file.

In the routing configuration file, we need to map all front-end requests to a handler. This handler will be responsible for receiving front-end requests and returning corresponding data based on the request content. The following is a simple routing configuration example:

<?php

use thinkacadeRoute;

// 前端路由
Route::rule('/*', 'index/index');

Copy after login

In the above code, we map all requests matching the /* rule to the index method of the index controller.

4. Writing the controller

In ThinkPHP6, the controller is responsible for receiving front-end requests and returning corresponding data according to the request content. In the front-end and back-end separation mode, we need to write a special controller to handle front-end requests.

The following is a sample controller code:

<?php

namespace apppicontroller;

use thinkRequest;
use thinkResponse;

class Index
{
    public function index(Request $request, Response $response)
    {
        // 处理前端请求
        $result = array(
            "code" => 200,
            "message" => "Hello, World!"
        );

        // 返回响应
        return json($result);
    }
}

Copy after login

In the above code, we define a controller named Index and write an index method in it to handle front-end requests. During the request processing process, we can access the database, read files and other operations according to business needs. Finally, we convert the processing results into JSON format and return them to the front end through the response object.

5. Writing the front-end page

In ThinkPHP6, the front-end page is responsible for displaying data and user interaction. We can use the Vue.js framework to write front-end pages, or use some other front-end frameworks or tools to implement it.

The following is a simple front-end page example:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>前后端分离示例</title>
    <script src="https://cdn.jsdelivr.net/npm/vue"></script>
</head>
<body>
    <div id="app">
        {{ message }}
    </div>
    <script>
        new Vue({
            el: '#app',
            data: {
                message: ''
            },
            mounted() {
                axios.get('/api/index')
                    .then(response => {
                        this.message = response.data.message;
                    });
            }
        });
    </script>
</body>
</html>

Copy after login

In the above code, we use the Vue.js framework to display data, and use the axios library to initiate an HTTP request to obtain data. By binding data to page elements, we can display the data obtained from the backend on the page.

6. Run the application

After we have completed the previous work, we can verify whether our front-end and back-end separation development is successful by running the application. Go to the ThinkPHP6 project directory we created in the terminal, and then use the following command to start the Web server:

php think run

Copy after login

Then, visit http://localhost:8000/ in the browser, you can see us Written front-end page. When we click a button or perform other interactive operations on the page, the request will be sent to the backend controller through routing. The controller will process the data according to the request content and return the processing results to the front-end page.

7. Summary

Separation of front-end and back-end is a common Web development model, which can improve development efficiency and application performance while reducing development costs. In this article, we introduce how to use ThinkPHP6 to achieve front-end and back-end separation, including routing configuration, controller writing, and front-end page display. I hope this article will be helpful to developers.
