Question

Middleware.js

var _ = require('underscore');
var db = require('./mongoose.js');

var middleWareFunctions = {}; //define middleware object (cont. functions)

var authenticate = function (req, res, next) {

    var token = req.header('x-auth');
    db.user.findByToken(token).then((result) => {

        if (!result) { //No found user.
            return Promise.reject();
        }
        req.user = user;
        req.token = token;
        next(); //Otherwise the other route won't run.
        ///The above req gets passed in to main route (this is the middle-ware).
    }).catch((e) => {
        res.status(401).send();
    });

};

middleWareFunctions.authenticate = authenticate;

module.exports = middleWareFunctions;

server.js

var {authenticate} = require('Middleware.js');

这准确吗？我在我的实际路线中使用它作为我的中间件，它似乎不起作用。我该如何引用这个对象？

我想检索authenticate对象内的middleWareFunctions函数。

export function authenticate (req, res, next) {

    var token = req.header('x-auth');
    db.user.findByToken(token).then((result) => {

        if (!result) { //No found user.
            return Promise.reject();
        }
        req.user = user;
        req.token = token;
        next(); //Otherwise the other route won't run.
        ///The above req gets passed in to main route (this is the middle-ware).
    }).catch((e) => {
        res.status(401).send();
    });

}

你尝试过这样的事吗？您可以导出任意数量的对象/函数，并在其他文件中访问它们 import { authenticate } from 'middleware';

如果您导出类似

的内容

export default function auth() {}

你会得到它

imoort auth from 'middleware'
