1.node-formidable

對檔案上傳提供幫助的元件

2.app.js

var formidable = require('formidable');
var http = require( 'http' );
var sys = require('sys');
 
http.createServer(function( request ,response ){
  if( request.url == '/upload' && request.method.toLowerCase() == 'post' )
  {
    console.log( 'upload requet ' )
    uploadRequest(request,response);
    return;
  }
  enterRequest(request,response)
}).listen(3000);
 
function enterRequest( request, response )
{
  response.writeHead( 200, { 'Content-type' : 'text/html' });
  response.end(
    &#39;<form action = "/upload" enctype="multipart/form-data" method="post" >&#39; +
    &#39;<input type = "text" name = "title" /> <br>&#39; +

  );
}
 
/**

 * @param request
 * @param response
 */
function uploadRequest( request,response )
{
  var form = new formidable.IncomingForm();
  form.parse( request, function ( err, fields, files ) {
    response.writeHead(200, {&#39;Content-type&#39; : &#39;text/plain&#39;});
    response.write(&#39;reviced upload file&#39;);
    response.end( sys.inspect(
      {
        fields : fields,
        files : files
      }) );
  });
