PSGI or Perl Web Server Gateway Interface is an interface between Web servers and Perl-based Web applications and frameworks that allows writing portable applications that can be run as standalone servers or using CGI, FastCGI, mod_perl, et al. It is inspired by the Web Server Gateway Interface for Python, Rack for Ruby and JSGI for JavaScript. A PSGI application is a Perl subroutine that accepts arguments as a single hash reference and returns a reference to an array of three elements: an HTTP status code, a reference to an array of HTTP headers and a reference to an array of HTTP body lines (usually a generated HTML document) or a filehandle-like object. Plack is a reference PSGI implementation. Web frameworks with PSGI support: * Catalyst * (CGI::Application ) * (Continuity ) * Dancer * (HTTP::Engine ) * (Leyland ) * Mason * Maypole * (McBain ) * Mojolicious * (Piglet ) * (Squatting ) * (Tatsumaki ) ==Example Application== This is an example hello world PSGI application: my $app = sub Save this file as hello.psgi and run it from the command-line: plackup hello.psgi 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PSGI」の詳細全文を読む スポンサード リンク
