Plack::Middleware::AccUseroContributed Perl DocPlack::Middleware::AccessLog(3)NAMEPlack::Middleware::AccessLog - Logs requests like Apache's log format
SYNOPSIS
# in app.psgi
use Plack::Builder;
builder {
enable "Plack::Middleware::AccessLog", format => "combined";
$app;
};
DESCRIPTIONPlack::Middleware::AccessLog forwards the request to the given app and
logs request and response details to the logger callback. The format
can be specified using Apache-like format strings (or "combined" or
"common" for the default formats). If none is specified "combined" is
used.
This middleware uses calculable Content-Length by checking body type,
and cannot log the time taken to serve requests. It also logs the
request before the response is actually sent to the client. Use
Plack::Middleware::AccessLog::Timed if you want to log details after
the response is transmitted (more like a real web server) to the
client.
This middleware is enabled by default when you run plackup as a default
"development" environment.
CONFIGURATION
format
enable "Plack::Middleware::AccessLog",
format => '%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-agent}i"';
Takes a format string (or a preset template "combined" or "custom")
to specify the log format. This middleware implements a subset of
Apache's LogFormat templates
<http://httpd.apache.org/docs/2.0/mod/mod_log_config.html>:
%% a percent sign
%h REMOTE_ADDR from the PSGI environment, or -
%l remote logname not implemented (currently always -)
%u REMOTE_USER from the PSGI environment, or -
%t [local timestamp, in default format]
%r REQUEST_METHOD, REQUEST_URI and SERVER_PROTOCOL from the PSGI environment
%s the HTTP status code of the response
%b content length
%T custom field for handling times in subclasses
%D custom field for handling sub-second times in subclasses
%v SERVER_NAME from the PSGI environment, or -
%V HTTP_HOST or SERVER_NAME from the PSGI environment, or -
Some of these format fields are only supported by middleware that
subclasses "AccessLog".
In addition, custom values can be referenced, using "%{name}", with
one of the mandatory modifier flags "i", "o" or "t":
%{variable-name}i HTTP_VARIABLE_NAME value from the PSGI environment
%{header-name}o header-name header
%{time-format]t localtime in the specified strftime format
logger
my $logger = Log::Dispatch->new(...);
enable "Plack::Middleware::AccessLog",
logger => sub { $logger->log(level => 'debug', message => @_) };
Sets a callback to print log message to. It prints to the
"psgi.errors" output stream by default.
