# DESCRIPTION

This is a refactoring/stealing of Catalyst's useful debugging output for use in
any Plack application, sitting infront of a web framework or otherwise. This is
ideal for development environments. You probably would not want to run this on
your production application.

One new feature that differentiates from Catalyst is that if serialized content
is sent via body param, an attempt will be made to deserialize based on the
Content-Type header with Data::Serializer.

This middleware will use psgix.logger if available in the environment,
otherwise it will fall back to printing to stderr.

There are a large list of attrs which can be used to control which
output you want to see:

- debug
- request
- response
- request\_headers
- request\_parameters
- response\_headers
- response\_status\_line
- keywords
- uploads
- body\_params
- query\_params
- attempt\_deserialize
- serializer

# NAME

Plack::Middleware::DebugLogging - Catalyst style console debugging for plack apps

# METHODS

## $self->log\_request

Writes information about the request to the debug logs.  This includes:

- Request method, path, and remote IP address
- Query keywords (see ["query\_keywords" in Catalyst::Request](https://metacpan.org/pod/Catalyst::Request#query_keywords))
- Request parameters
- File uploads

## $self->log\_response

Writes information about the response to the debug logs by calling
`$self->log_response_status_line` and `$self->log_response_headers`.

## $self->log\_response\_status\_line($response)

Writes one line of information about the response to the debug logs.  This includes:

- Response status code
- Content-Type header (if present)
- Content-Length header (if present)

## $self->log\_request\_parameters( query => {}, body => {} )

Logs request parameters to debug logs

## $self->log\_request\_uploads

Logs file uploads included in the request to the debug logs.
The parameter name, filename, file type, and file size are all included in
the debug logs.

## $self->log\_headers($type => $headers)

Logs [HTTP::Headers](https://metacpan.org/pod/HTTP::Headers) (either request or response) to the debug logs.
