yii2 restful api front-end use

Using Yii2 to build a RESTful API, you can use the Axios library or the Fetch API to call it on the front end. The specific steps are: build a RESTful API: enable the Yii2 RESTful API module and create an API controller. Front-end call: Use the Axios library: Call the API through the axios.get() method. Use the Fetch API: Call the API through the fetch() method and then() method. Tips: Use authentication to ensure that only authorized users can access the API. Send request parameters to filter and sort the API. Handle errors, parse

Use Yii2 to build a RESTful API, front-end call

1. Build a RESTful API

Use Yii2's RESTful API module to easily create REST-compliant APIs:

 <code class="php">// 启用RESTful API 模块// config/web.php 'modules' => [ 'api' => 'app\modules\api\Module', ], // 创建一个API 控制器// app/modules/api/controllers/PostController.php namespace app\modules\api\controllers; use Yii; use yii\rest\ActiveController; use app\models\Post; class PostController extends ActiveController { public $modelClass = 'app\models\Post'; }</code>

2. Front-end call

Using the Axios library

Axios is a popular front-end HTTP client library that can be used to call the RESTful API:

 <code class="javascript">// 安装Axios 库npm install axios // 调用API 获取文章列表axios.get('/api/posts') .then(response => { // 处理响应，例如更新UI }) .catch(error => { // 处理错误});</code>

Using the Fetch API

The native Fetch API can also be used to call the RESTful API:

 <code class="javascript">// 获取文章列表fetch('/api/posts') .then(response => response.json()) .then(data => { // 处理响应数据，例如更新UI }) .catch(error => { // 处理错误});</code>

3. Usage Tips

• Using Authentication: The Yii2 RESTful API enables authentication easily, ensuring that only authorized users can access the API.
• Send request parameters: You can carry parameters when calling a request, such as filtering and sorting the API.
• Handling errors: The Yii2 RESTful API automatically handles the error and returns a standard JSON response for easy front-end parsing.
