NAME¶
Dancer2::Core::Error - Class representing fatal errors
VERSION¶
version 0.152000
SYNOPSIS¶
# taken from send_file:
use Dancer2::Core::Error;
my $error = Dancer2::Core::Error->new(
status => 404,
message => "No such file: `$path'"
);
Dancer2::Core::Response->set($error->render);
DESCRIPTION¶
With Dancer2::Core::Error you can throw reasonable-looking errors to the user
instead of crashing the application and filling up the logs.
This is usually used in debugging environments, and it's what Dancer2 uses as
well under debugging to catch errors and show them on screen.
ATTRIBUTES¶
show_errors¶
charset¶
type¶
The error type.
title¶
The title of the error page.
This is only an attribute getter, you'll have to set it at "new".
status¶
The status that caused the error.
This is only an attribute getter, you'll have to set it at "new".
message¶
The message of the error page.
METHODS¶
my $error=new Dancer2::Core::Error(status => 404, message => "No such file: `$path'");¶
Create a new Dancer2::Core::Error object. For available arguments see
ATTRIBUTES.
supported_hooks ();¶
throw($response)¶
Populates the content of the response with the error's information. If
$response is not given, acts on the
app
attribute's response.
backtrace¶
Create a backtrace of the code where the error is caused.
This method tries to find out where the error appeared according to the actual
error message (using the "message" attribute) and tries to parse it
(supporting the regular/default Perl warning or error pattern and the
Devel::SimpleTrace output) and then returns an error-highlighted
"message".
tabulate¶
Small subroutine to help output nicer.
environment¶
A main function to render environment information: the caller (using
"get_caller"), the settings and environment (using
"dumper") and more.
get_caller¶
Creates a stack trace of callers.
FUNCTIONS¶
_censor¶
An private function that tries to censor out content which should be protected.
"dumper" calls this method to censor things like passwords and such.
my $string=_html_encode ($string);¶
Private function that replaces illegal entities in (X)HTML with their escaped
representations.
html_encode() doesn't do any UTF black magic.
dumper¶
This uses Data::Dumper to create nice content output with a few predefined
options.
