spawn-perl v0.2.0

spawn-perl

A CGI webserver for perl. Great for use if you don't have access to Apache or IIS environment. A quick script for development purposes.

Usage in Node and express

var Perlcgi = require('./spawn-perl').spawnPerlCGI;
var express = require('express')
  ,http = require('http')
  ,url = require('url')
  ,path = require('path');
var app = express();
var script_name = '/cgi-bin/guest.cgi';

var script = path.join(__dirname, '/cgi-bin/guest.cgi');

  app.set('port', process.env.PORT || 3000);


app.get(script_name, function(req, res){
      var perl = new Perlcgi(script,req,null,function(err,data){
       
       
                 
			   if(err){
                console.log(err);
				}
             
                 res.header(perl.getHeader());
                 res.write(data);
                 res.end();
				});                    
   });

app.post(script_name, function(req, res){
       var perl = new Perlcgi(script,req,null,function(err,data){
		 
       if(err){              
                console.log(err);
				}                
                 res.header(perl.getHeader());
                 res.write(data);
                 res.end();
       });
   });
 
http.createServer(app).listen(app.get('port'), function(){
  console.log("Express server listening on port " + app.get('port'));
});

To use the example app.js, make sure you install express.

   $ cd src
   $ npm install express

Features

• CGI Environment created for you, or you can pass own %ENV in the 3rd parameter
• The CGI header is removed from the stdout of the Perl script, so you can pass own header in using the express framework, or you can use the CGI header by calling the getHeader() method which returns a json object, and passing as parameter in response.header()
• CGI error and data are returned in Callback as function(err,data){}. This allows you to write own error response back to client in response object
• Tested with both Windows, using Strawberry Perl, and UBuntu.

• An example Blog written in Perl is included in cgi-bin folder
