I. The role of ThinkPHP 5.0 error page
The error page is mainly used to capture errors that occur when the application is running and Provides access to the error log.
The error page also supports real-time recording of error information, which can quickly troubleshoot and solve errors in the production environment.
II. Configuring the error page
Configuring the error page needs to be done in the application's configuration file, for example in config.php
Add the following configuration to the file:
'exception_handle' => 'app\index\exception\Http',
where app\index\exception\Http
refers to the namespace and class name of the exception handling class. The exception handling class needs to inherit the think\exception\Handle
class and override the render
method to output custom exception information.
III. Default settings for error pages
The default error page in ThinkPHP 5.0 contains the following:
Exception class Name
Exception error code
Exception error description
Exception error file and line number
Exception traceback information
The above information can help quickly locate the error location and perform tracking analysis. In addition, the error page also provides action buttons so that developers can perform some common operations.
IV. Custom error page
The error page also supports customization, just inherit the think\exception\Handle
class in the controller , and rewrite the render
method, for example:
namespace app\index\exception; use think\exception\Handle; class Http extends Handle { public function render(\Exception $e) { if ($e instanceof HttpException) { $status = $e->getStatusCode(); } else { $status = 404; } $data = [ 'status' => $status, 'message' => $this->getMessage($e), 'exception' => $this->isDebug() ? $this->getTrace($e) : [], ]; return json($data); } }
The above code shows how to customize exception information and return error information in JSON object format when an error occurs.
