Let's talk about how thinkphp realizes the development of front-end and back-end separation

With the rapid development of Internet technology, the development method of separating front and back ends is increasingly favored by developers. In traditional front-end and back-end coupled development, the front and back ends even need to share the same set of templates, which greatly limits the freedom and flexibility of development. The front-end and back-end separation development method allows the front-end and back-end to each focus on their own development work, which not only makes development more efficient, but also improves the maintainability and scalability of the program. So, how does thinkphp realize the development of front-end and back-end separation?

1. Cross-domain access

In development where the front-end and back-end are separated, the front-end usually uses ajax to asynchronously request the back-end interface. However, in cross-domain situations, the front-end cannot access the back-end interface. end interface, so it needs to be set up on the backend. You can use the think-cors extension in thinkphp to implement cross-domain requests. You only need to configure it accordingly in the config.php file:

'cors' => [
    'allow-origin' => ['*'],
    'allow-credentials' => true,
    'allow-methods' => ['GET, POST, PATCH, PUT, DELETE,OPTIONS'],
    'allow-headers' => ['Content-Type, Authorization, X-Requested-With, Accept'],
    'expose-headers' => ['Guzzle-Supported'],
    'max-age' => 0,
],

2. Interface Development

In the development of separate front-end and back-end, the back-end must provide a set of API interfaces that meet the regulations to the front-end, and the front-end calls them. Therefore, the specification and design of the interface are also very important. In thinkphp, you can use the RESTful style API for interface development. The RESTful style uses a unified resource locator (URL) to represent resources, and uses HTTP protocol methods to represent operations on resources, including GET, POST, PUT, and DELETE. and other methods.

3. Data format

Another important factor in front-end and back-end interaction is the data format. Generally speaking, the backend needs to provide data in JSON or XML format, and the frontend performs data rendering by requesting these data through ajax. Therefore, in thinkphp, you need to pay attention to the specifications of the returned data format.

return json(['code' => 200, 'msg' => '请求成功', 'data' => ['id' => 1, 'name' => 'thinkphp']]);

4. Front-end implementation

thinkphp provides a rich template engine that can support smart, blade, twig and other template engines to adapt to a variety of front-end development needs. Front-end developers can use popular MVVM frameworks such as Vue and React for front-end development to achieve more efficient and complex front-end requirements.

Summary

This article introduces how thinkphp develops front-end and back-end separation, including cross-domain access, interface development, data format, front-end implementation, etc., aiming to help developers gain a deeper understanding of the front-end and back-end The ideas and methods of end-side separation development and help them develop in a more efficient and standardized way.
