yii 500 error page settings
yii2 custom 500 error
Since the project wants to add early warning monitoring, one of them involves 500 errors within the program. Such error levels are relatively high, so it is necessary to capture such errors and customize a view style
Recommended learning: yii framework
After reading this blog, I know how to customize my own error page: http://tech.lubanr.com/2015/12/12/ Error and exception handling mechanism of yii2-0 framework/
If we need to customize our own exception handling method, all we need to do is inherit yii\base\ErrorHandler, write a customized renderException, and finally customize it in $config Your own errorHandler
1. Create an ErrorHandler and inherit this yii\base\ErrorHandler abstract class, and then define the abstract method in this parent class
<?php namespace common\component\exception; /** * User: szliugx@gmail.com * Date: 2016/9/20 * Time: 14:24 */ use yii; use yii\base\ErrorHandler as BaseErrorHandler; use common\component\earlywarning\EarlyWarning; class ErrorHandler extends BaseErrorHandler { public $errorView = '@app/views/errorHandler/error.php'; public function renderException($exception) { if(Yii::$app->request->getIsAjax()){ exit( json_encode( array('code' =>$exception->getCode(),'msg' =>$exception->getMessage()) )); }else{ //将500的代码,发送监控预警 if(!empty($exception->getCode()) && $exception->getCode() ==8){ $params = []; $params['projectName'] = "oct-youban"; $params['level'] = 5; $params['title'] = "500:".$exception->getMessage(); $params['value'] = $exception->getCode(); $params['message'] = $exception->getFile().":".$exception->getLine(); $params['bizcode'] = 8; $params['subcode'] = 8001; EarlyWarning::WarninApi($params); } echo Yii::$app->getView()->renderFile($this->errorView,['exception' => $exception,],$this); } } }
2. Create a view file : @app/views/errorHandler/error.php
<?php /** * User: szliugx@gmail.com * Date: 2016/9/20 * Time: 15:23 */ ?> <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <meta name="format-detection" content="telephone=no"> <meta http-equiv="Expires" content="-1"> <meta http-equiv="Cache-Control" content="no-cache"> <meta http-equiv="Pragma" content="no-cache"> <title><?php if(!empty($exception->getCode())&&($exception->getCode() == 8)){echo "出错啦";}else{ echo $exception->getMessage();}?></title> <link href="/css/error.css" rel="stylesheet" 0="frontend\assets\AppAsset"> </head> <body> <div> <div class="status-icon icon-desk"></div> <div> <p><?php if(!empty($exception->getCode())&&($exception->getCode() == 8)){echo "出错啦";}else{ echo $exception->getMessage();}?></p> </div> </div> </body> </html>
3. Modify the application configuration file: @app/config/main.php
'errorHandler' => [ //'errorAction' => 'site/error', 'class' => 'common\component\exception\ErrorHandler', ],
Modify the above three places to achieve the desired purpose. The effect is as follows:
500 error page:
404 error page:

Yii is a high-performance PHP framework that is unique in its componentized architecture, powerful ORM and excellent security. 1. The component-based architecture allows developers to flexibly assemble functions. 2. Powerful ORM simplifies data operation. 3. Built-in multiple security functions to ensure application security.

Yii framework adopts an MVC architecture and enhances its flexibility and scalability through components, modules, etc. 1) The MVC mode divides the application logic into model, view and controller. 2) Yii's MVC implementation uses action refinement request processing. 3) Yii supports modular development and improves code organization and management. 4) Use cache and database query optimization to improve performance.

Strategies to improve Yii2.0 application performance include: 1. Database query optimization, using QueryBuilder and ActiveRecord to select specific fields and limit result sets; 2. Caching strategy, rational use of data, query and page cache; 3. Code-level optimization, reducing object creation and using efficient algorithms. Through these methods, the performance of Yii2.0 applications can be significantly improved.

Developing a RESTful API in the Yii framework can be achieved through the following steps: Defining a controller: Use yii\rest\ActiveController to define a resource controller, such as UserController. Configure authentication: Ensure the security of the API by adding HTTPBearer authentication mechanism. Implement paging and sorting: Use yii\data\ActiveDataProvider to handle complex business logic. Error handling: Configure yii\web\ErrorHandler to customize error responses, such as handling when authentication fails. Performance optimization: Use Yii's caching mechanism to optimize frequently accessed resources and improve API performance.

In the Yii framework, components are reusable objects, and extensions are plugins added through Composer. 1. Components are instantiated through configuration files or code, and use dependency injection containers to improve flexibility and testability. 2. Expand the management through Composer to quickly enhance application functions. Using these tools can improve development efficiency and application performance.

Theming and Tempting of the Yii framework achieve website style and content generation through theme directories and views and layout files: 1. Theming manages website style and layout by setting theme directories, 2. Tempting generates HTML content through views and layout files, 3. Embed complex UI components using the Widget system, 4. Optimize performance and follow best practices to improve user experience and development efficiency.

When preparing for an interview with Yii framework, you need to know the following key knowledge points: 1. MVC architecture: Understand the collaborative work of models, views and controllers. 2. ActiveRecord: Master the use of ORM tools and simplify database operations. 3. Widgets and Helpers: Familiar with built-in components and helper functions, and quickly build the user interface. Mastering these core concepts and best practices will help you stand out in the interview.
