Nodejs file upload

在server端需要加入，主要為上傳到暫存資料夾，然後刪除再將檔案移動至想要的資料夾中

	app.post('/upload', function(req, res){
	data = req.body;
	// get the temporary location of the file
	console.log('file => '+req.files);
	var tmp_path = req.files.file.path;
	// set where the file should actually exists - in this case it is in the "images" directory
	var target_path = './public/images/'+ req.files.file.name;
	// move the file from the temporary location to the intended location
	console.log('tmp_path = '+tmp_path+' || target_path = '+target_path);
	fs.rename(tmp_path, target_path, function(err) {
	if (err) throw err;
	// delete the temporary file, so that the explicitly set temporary upload dir does not get filled with unwanted files
	fs.unlink(tmp_path, function() {
	if (err) throw err;
	res.send('upload success!');
	});
	});
	});

html使用form方式加入，使用bootstrap的CSS將畫面美化

	<form class="form-horizontal" action="/upload" method="post" enctype="multipart/form-data">
	<div class="control-group">
	<label class="control-label">File upload</label>
	<div class="controls">
	<input type="file" name="file" class="btn-large">
	</div>
	</div>
	<div class="control-group">
	<div class="controls">
	<button type="submit" class="btn btn-large btn-primary">Submit</button>
	</div>
	</div>
	</form>
