How to configure error page in thinkphp5.0

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:

1. Exception class Name

2. Exception error code

3. Exception error description

4. Exception error file and line number

5. 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.
