use Wallflower; my $w = Wallflower->new( application => $app, # a PSGI app destination => $dir, # target directory ); # dump all URL from $app to files in $dir $w->get( $_ ) for @urls;
new( %args )
Create a new Wallflower object.
The parameters are:
The PSGI/Plack application, as a CODE reference.
This parameter is required.
The destination directory. Default is the current directory.
The destination directory must exist.
Additional environment key/value pairs.
The default filename for URLs ending in
/. The default value is index.html.
get( $url )
GET request for
$url through the application, and if successful, save the result to a filename derived from
$url by the
$url can be either a string or a URI object, representing an absolute URL (the path must start with a
/). The scheme, host, port, and query string are ignored if present.
The return value is very similar to a Plack application's:
[ $status, $headers, $file ]
$headers are those returned by the application itself for the given
$file is the name of the file where the content has been saved.
If a file exists at the location pointed to by the target, a
If-Modified-Since header is added to the Plack environment, with the modification timestamp for this file as the value. If the application sends a
304 Not modified in response, the target file will not be modified.
target( $uri )
Return the filename where the content of
$uri will be saved.
path component of
$uri is concatenated to the
destination attribute. If the URL ends with a
index attribute is appended to create a file path.
$uri is a URI object, and that it must be absolute.
Accessors (getters only) exist for all parameters to
new() and bear the same name.
