API-Reference: wsgi_tools.error()

This module includes the abstract WSGI-app wsgi_tools.error.ErrorHandler(). It simply calls the WSGI-app, specified in the constructor. If a wsgi_tools.error.HTTPException() occurs, the wsgi_tools.error.ErrorHandler() will handle it using the abstract wsgi_tools.error.ErrorHandler.handle() method. If any other exception occurs, the wsgi_tools.error.ErrorHandler() will create a 500 Internal Server Error and handle it.

There are two implementations of wsgi_tools.error.ErrorHandler() in this module, but you can do your own as well:

  • wsgi_tools.error.JSONErrorHandler():

    The handle method returns a json-string of an object, with entries for code, error and message, if the message was set in the wsgi_tools.error.HTTPException().

    The internal server error thrown by the handler, will be:

    {
    "code": 500, 
    "error": "Internal Server Error", 
    "message": "A server error occurred. Please contact an administrator."
}

  • wsgi_tools.error.HTMLErrorHandler():

    The handle method returns an html-string, which is human readable in the browser.

    The internal server error thrown by the handler, will be:

    <html><head><title>500 Internal Server Error</title></head><body><h1>500 Internal Server Error</h1><p>A server error occurred. Please contact an administrator.</p></body></html>
