如何使用 Node.js 上传文件?

问题描述 投票:0回答:1

我已经看过 使用 Node.js、Express 和 Mongoose 上传图像,但我正在使用带有

ExpressJS
的 MVC 架构。在我的 app.coffee 中,我正在做:

app.configure(function() {
  app.set('views', __dirname + '/views');
  app.set('view engine', 'ejs');
  app.use(form({
    keepExtensions: true
  }));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.cookieParser());
  app.use(express.session(sessionVariables));
  app.use(app.router);
  return app.use(express.static(__dirname + '/public'));
});

在我的控制器方法中,我正在做:

exports.uploadCustomersApi = function(req, res) {
  return console.log(req);
};

但是

form
中似乎没有
req
元素。关于我做错了什么有什么想法吗?

编辑:发布我的

req
对象

此模块现已弃用,最终将被删除,Connect >= 1.8.0 bodyParser() 支持 multipart/form-data,填充 req.body 就像 application/json 一样。核心 bodyParser() 的替代方案已分离。

connect-form 已弃用。使用主体解析器,它理解多部分/表单数据。

具体来说,bodyParser 将写入

req.files
。去阅读 bodyParser 示例
