To install formidable, run the command in your working directory:
$ npm install formidable
Example code, app.js (tested on Raspberry Pi and Ubuntu):
// run the command to install formidable
// $ npm install formidable
var formidable = require('formidable');
var http = require('http');
var util = require('util');
var fs = require('fs');
var os = require('os');
var app = http.createServer(
function(req, res){
switch(req.method){
case 'GET':
showPage(req, res);
break;
case 'POST':
upload(req, res);
break;
}
}
);
app.listen(8080);
//Display my IP
var networkInterfaces=os.networkInterfaces();
for (var interface in networkInterfaces) {
networkInterfaces[interface].forEach(
function(details){
if (details.family=='IPv4'
&& details.internal==false) {
console.log(interface, details.address);
}
});
}
function showPage(req, res){
fs.readFile(__dirname + '/index.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200);
res.end(data);
});
}
function upload(req, res){
var form = new formidable.IncomingForm();
form.parse(req, function(err, fields, files) {
res.writeHead(200, {'content-type': 'text/plain'});
res.end('File uploaded!');
console.log("Upload completed");
console.log(util.inspect(files));
});
}
