yii2 restful api front-end use

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">// 啟用RESTful API 模塊// config/web.php 'modules' => [ 'api' => 'app\modules\api\Module', ], // 創(chuàng)建一個(gè)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">// 安裝Axios 庫(kù)npm install axios // 調(diào)用API 獲取文章列表axios.get('/api/posts') .then(response => { // 處理響應(yīng),例如更新UI }) .catch(error => { // 處理錯(cuò)誤});</code>

Using the Fetch API

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

 <code class="javascript">// 獲取文章列表fetch('/api/posts') .then(response => response.json()) .then(data => { // 處理響應(yīng)數(shù)據(jù),例如更新UI }) .catch(error => { // 處理錯(cuò)誤});</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.

You need to manually download PHP and configure environment variables on Windows, then install Composer, use commands to create a project and run a built-in server; 2. It is recommended to use Homebrew to install PHP and Composer, then create a project and start a development server; 3. Linux (such as Ubuntu) install PHP, extensions and Composer through apt, then create a project and deploy a formal environment with Apache or Nginx.

How do I display validation errors in a form? How do I display validation errors in a form? Jun 19, 2025 am 12:02 AM

It is crucial to clearly display verification errors when the user submits the form information incorrectly or missing. 1. Use inline error messages to directly display specific errors next to the relevant fields, such as "Please enter a valid email address", rather than general prompts; 2. Mark the problem fields visually by red borders, background colors or warning icons to enhance readability; 3. When the form is long or the structure is complex, display a click-through summary of the error that can be clicked and jumped at the top, but it needs to be used in conjunction with inline messages; 4. Enable real-time verification in the appropriate situation, and instant feedback when the user enters or leaves the field, such as checking the email format or password strength, but avoiding prompting too early before the user submits. These methods can effectively guide users to quickly correct input errors and improve the form filling experience.
