UR::Service::WebServer - A PSGI-based web server
my $s = UR::Service::WebServer(port => 4321); $s->run( \&handle_request );
Implements a simple, standalone web server based on HTTP::Server::PSGI. The event loop is entered by calling the run() method.
The IP address to listen on for connections. The default value is 'localhost'. host can be changed any time before the server is created, usually the first time run() is called.
The TCP port to listen on for connections. The detault value is undef, meaning that the system will pick an unused port. port can be changed any time before the server is created, usually the first time run() is called.
Holds a reference to an object that isa HTTP::Server::PSGI. This will be automaticly created the first time run() is called.
Holds a CODE reference used as the default request handler within run().
This method is called when the PSGI server is ready to accept requests. The base-class behavior is to print the listening URL on STDOUT. Subclasses can override it to implement their own behavior.
- my $code = $self->file_handler_for_directory($path)
A helper method used for implementing server for files located in the directory $path. It returns a CODE ref that takes 2 arguments, $env (the standard PSGI env hashref) and $pathname (a path relative to $path). It returns the standard tuple a PSGI server expects.
$pathname is pre-processed by removing all occurances of ".." to keep requests within the provided $path. If the requested file is not found, then it returns a 404.
Enter the request loop. If a callback is not provided to run(), then the object's cb property is used instead. If neither have a value, then run() returns immediately.
For each request $cb is called with one argument, the standard PSGI env hashref.
