Nodejs---Formidable module, post upload.

1. There is only one file field:

1 varFormidable = require (' formidable ')),2HTTP = require (' http '),3Util = require (' util '));4 5Http.createserver (function(req, res) {6   if(Req.url = = '/upload ' && req.method.toLowerCase () = = ' Post ') {7     //parse a file upload8     varform =NewFormidable. Incomingform ();9Form.parse (req,function(Err, fields, files) {TenRes.writehead, {' Content-type ': ' Text/plain '}); OneRes.write (' Received upload:\n\n '); A Res.end (Util.inspect ({fields:fields, files:files})); -     }); -     return; the   } -  -   //show a file upload form -Res.writehead, {' Content-type ': ' text/html '}); + Res.end ( -' <form action= '/upload "enctype=" multipart/form-data "' + +' method= ' post > ' + A  at' <input type= ' file ' name= ' upload ' multiple= ' multiple ' ><br> ' + -' <input type= ' submit ' value= ' Upload ' > ' + -' </form> ' -   ); -}). Listen (8888);

2. Multiple file uploads:

No, the last selection covers the previous one.

3. Two different file domains:

1 varFormidable = require (' formidable ')),2HTTP = require (' http '),3Util = require (' util '));4 5Http.createserver (function(req, res) {6   if(Req.url = = '/upload ' && req.method.toLowerCase () = = ' Post ') {7     //parse a file upload8     varform =NewFormidable. Incomingform ();9Form.parse (req,function(Err, fields, files) {TenRes.writehead, {' Content-type ': ' Text/plain '}); OneRes.write (' Received upload:\n\n '); A Res.end (Util.inspect ({fields:fields, files:files})); -     }); -     return; the   } -  -   //show a file upload form -Res.writehead, {' Content-type ': ' text/html '}); + Res.end ( -' <form action= '/upload "enctype=" multipart/form-data "' + +' method= ' post > ' + A  at' <input type= ' file 'name= "UPLOAD01"><br> ' + -' <input type= ' file 'name= "UPLOAD02"><br> ' + -' <input type= ' submit ' value= ' Upload ' > ' + -' </form> ' -   ); -}). Listen (8888);

4. Remove the file field, there are other fields.

1 varFormidable = require (' formidable ')),2HTTP = require (' http '),3Util = require (' util '));4 5Http.createserver (function(req, res) {6   if(Req.url = = '/upload ' && req.method.toLowerCase () = = ' Post ') {7     //parse a file upload8     varform =NewFormidable. Incomingform ();9Form.parse (req,function(Err, fields, files) {TenRes.writehead, {' Content-type ': ' Text/plain '}); OneRes.write (' Received upload:\n\n '); A Res.end (Util.inspect ({fields:fields, files:files})); -     }); -     return; the   } -  -   //show a file upload form -Res.writehead, {' Content-type ': ' text/html '}); + Res.end ( -' <form action= '/upload "enctype=" multipart/form-data "' + +' method= ' post > ' + A' <input type= ' text 'name= "UserName"><br> ' + at' <input type= ' password 'name= "Password"><br> ' + -' <input type= ' file 'name= "UPLOAD01"><br> ' + -' <input type= ' file 'name= "UPLOAD02"><br> ' + -' <input type= ' submit ' value= ' Upload ' > ' + -' </form> ' -   ); in}). Listen (8888);
