基于nodejs+express(4.x+)实现文件上传功能

router.post('/file/uploading', function(req, res, next){
//生成multiparty对象，并配置上传目标路径
var form = new multiparty.Form({uploadDir: './public/files/'});
//上传完成后处理
form.parse(req, function(err, fields, files) {
var filesTmp = JSON.stringify(files,null,);
if(err){
console.log('parse error: ' + err);
} else {
console.log('parse files: ' + filesTmp);
var inputFile = files.inputFile[];
var uploadedPath = inputFile.path;
var dstPath = './public/files/' + inputFile.originalFilename;
//重命名为真实文件名
fs.rename(uploadedPath, dstPath, function(err) {
if(err){
console.log('rename error: ' + err);
} else {
console.log('rename ok');
}
});
}
res.writeHead(, {'content-type': 'text/plain;charset=utf-'});
res.write('received upload:nn');
res.end(util.inspect({fields: fields, files: filesTmp}));
});
});
module.exports = router;

完成。基于nodejs+express(4.x+)实现文件上传功能就全部介绍完了，希望对大家学习nodejs express相关知识有所帮助。
