1. 只有一个文件域:

 1 var formidable = require(‘formidable‘),
 2     http = require(‘http‘),
 3     util = require(‘util‘);
 4 
 5 http.createServer(function(req, res) {
 6   if (req.url == ‘/upload‘ && req.method.toLowerCase() == ‘post‘) {
 7     // parse a file upload
 8     var form = new formidable.IncomingForm();
 9     form.parse(req, function(err, fields, files) {
10       res.writeHead(200, {‘content-type‘: ‘text/plain‘});
11       res.write(‘received upload:\n\n‘);
12       res.end(util.inspect({fields: fields, files: files}));
13     });
14     return;
15   }
16 
17   // show a file upload form
18   res.writeHead(200, {‘content-type‘: ‘text/html‘});
19   res.end(
20     ‘<form action="/upload" enctype="multipart/form-data" ‘+
21     ‘method="post">‘+
22 
23     ‘<input type="file" name="upload" multiple="multiple"><br>‘+
24     ‘<input type="submit" value="Upload">‘+
25     ‘</form>‘
26   );
27 }).listen(8888);

2. 多文件上传:

不可以,最后一个选择的覆盖住了之前的.

3. 两个不同的文件域:

 1 var formidable = require(‘formidable‘),
 2     http = require(‘http‘),
 3     util = require(‘util‘);
 4 
 5 http.createServer(function(req, res) {
 6   if (req.url == ‘/upload‘ && req.method.toLowerCase() == ‘post‘) {
 7     // parse a file upload
 8     var form = new formidable.IncomingForm();
 9     form.parse(req, function(err, fields, files) {
10       res.writeHead(200, {‘content-type‘: ‘text/plain‘});
11       res.write(‘received upload:\n\n‘);
12       res.end(util.inspect({fields: fields, files: files}));
13     });
14     return;
15   }
16 
17   // show a file upload form
18   res.writeHead(200, {‘content-type‘: ‘text/html‘});
19   res.end(
20     ‘<form action="/upload" enctype="multipart/form-data" ‘+
21     ‘method="post">‘+
22 
23     ‘<input type="file" name="upload01" ><br>‘+
24     ‘<input type="file" name="upload02"><br>‘+
25     ‘<input type="submit" value="Upload">‘+
26     ‘</form>‘
27   );
28 }).listen(8888);

4. 除去文件域 , 有其他的字段.

 1 var formidable = require(‘formidable‘),
 2     http = require(‘http‘),
 3     util = require(‘util‘);
 4 
 5 http.createServer(function(req, res) {
 6   if (req.url == ‘/upload‘ && req.method.toLowerCase() == ‘post‘) {
 7     // parse a file upload
 8     var form = new formidable.IncomingForm();
 9     form.parse(req, function(err, fields, files) {
10       res.writeHead(200, {‘content-type‘: ‘text/plain‘});
11       res.write(‘received upload:\n\n‘);
12       res.end(util.inspect({fields: fields, files: files}));
13     });
14     return;
15   }
16 
17   // show a file upload form
18   res.writeHead(200, {‘content-type‘: ‘text/html‘});
19   res.end(
20     ‘<form action="/upload" enctype="multipart/form-data" ‘+
21     ‘method="post">‘+
22     ‘<input type="text" name="userName" ><br>‘+
23     ‘<input type="password" name="password" ><br>‘+
24     ‘<input type="file" name="upload01" ><br>‘+
25     ‘<input type="file" name="upload02"><br>‘+
26     ‘<input type="submit" value="Upload">‘+
27     ‘</form>‘
28   );
29 }).listen(8888);
