如何在meteor应用程序中正确configuration节点中间件
我已经在我的meteor应用程序中安装了multer中间件：
{ "multer": "0.1.8" } 我有meteorhack：npm也安装了
现在，我正在尝试这样configurationmiddlware：
var multer = Meteor.npmRequire('multer'); Meteor.app .use(multer({ dest: './uploads/', rename: function (fieldname, filename) { return filename+Date.now(); }, onFileUploadStart: function (file) { console.log(file.originalname + ' is starting ...'); }, onFileUploadComplete: function (file) { console.log(file.fieldname + ' uploaded to ' + file.path); var fileName = file.name; var done=true; } }));
当只有第一行时，我没有任何问题。
但是，当我试图实际configuration中间件时，出现以下错误：

所以看起来，Meteor对象没有名为“app”的属性。
在那种情况下，完成这个的正确语法是什么？
meteor使用connect来处理服务器端路由和中间件。
webapp包暴露了一个WebApp对象，它具有一个connectHandlers属性，您可以在其中添加自己的中间件。
WebApp.connectHandlers.use(multer({ dest: './uploads/', [...] }));
