node.js - Receiving submitted POST file Object in server side Javascript -

when user sends multi part form files/images selected, in meteor or node.js, server side post url handler uses this.request or req or request object detect whether post method or other , headers etc don't understand is, file located @ request object , how retrieve can used image/file upload or manipulations @ server?

node provides querystring api parse strings like:

foo=bar&baz=qux&baz=quux&corge 

...which how multi part form data sent. parsing api return object:

{ foo: 'bar', baz: ['qux', 'quux'], corge: '' } 

so, can first detect method of request, , if post, can attach handler 'data', data own variable, , on 'end' , parse using querystring:

var qs = require('querystring');  // request callback function like: function (request,response){     if(request.method=='post'){         var body = '';         request.on('data',function(data){             body += data;              //reject requests have sent data (eg 2mb):             if(body.length > 2e6){                 // send http status code `request entity large`:                 response.writehead(413);                  response.end();         });         request.on('end', function(){              var form = qs.parse(body);              //use form object         });     } // end if } // end handler
