Javascript 将对象传递到passport的require（）时出现typeError

我得到typeError:对象不是函数

当我跑步时：

node server.js

对于下面的代码行

require('./app/routes.js')(app, passport);

我的server.js文件的以下代码：

// server.js

// set up ======================================================================
// get all the tools we need
var express = require('express');
var app = express();
var port = process.env.PORT || 8080;
var mongoose = require('mongoose');
var passport = require('passport');
var flash = require('connect-flash');

var morgan = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var session = require('express-session');

var configDB = require('./config/database.js');

// configuration ================================================================
mongoose.connect(configDB.url); // connect to our database

// require('./config/passport')(passport); // pass passport for configuration


// set up our express application
app.use(morgan('dev')); // log every request to the console
app.use(cookieParser()); // read cookies (needed for auth)
app.use(bodyParser.json()); // get info from html forms
    app.use(bodyParser.urlencoded({ extended: true}));

app.set('view engine', 'ejs'); // set up ejs for templating

// requirements for passport:
app.use(session({ secret: 'ilovescotchscotchyscotchscotch'}));
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session

// routes ========================================================================
require('./app/routes.js')(app, passport); // load our routes and pass in our app and fully configured passport

// launch =======================================================================
app.listen(port);
console.log('The magic happens on port ' + port);

不完全确定为什么会发生这种情况

顺便说一句，我遵循了本教程：

根据您的评论：这很好地解释了require在nodeJS中的工作原理（它不是Javascript）。基本上，每个需要的文件通常都会导出需要的文件可以分配给变量的内容（例如，

var-someVar=require（'someFile'）；

）如果导出的值是一个函数，那么您可以在分配给该变量之前立即调用它（例如，

var-someVar=require（'someFile'）（params）；

）。对于您的错误，文件

/app/routes.js

似乎没有导出函数

文件：./app/routes.js

// some code that does cool stuff
// ...
// Time to expose whatever we want to the requiring file
module.exports = someObject; // Or value, function, etc.

// we want cool stuff from routes.js
var coolStuff = require('./app/routes.js');

// someObject from ./app/routes.js is now assigned to coolStuff
coolStuff(); // ERROR: object is not a function

console.log(typeof coolStuff) // "object"

文件：main.js

// some code that does cool stuff
// ...
// Time to expose whatever we want to the requiring file
module.exports = someObject; // Or value, function, etc.

// we want cool stuff from routes.js
var coolStuff = require('./app/routes.js');

// someObject from ./app/routes.js is now assigned to coolStuff
coolStuff(); // ERROR: object is not a function

console.log(typeof coolStuff) // "object"

这意味着从

/app/routes.js

导出的任何内容都不是函数。您是否检查了该文件分配给

导出

对象的内容？对不起，我对语法理解不够。您的意思是，在javascript中，当您确实需要（“”）（对象）时，它将对象分配给“”中的任何对象吗？如果是这样的话，那么我的语法不是正确的吗，因为app和passport都是对象？你能发布

app/routes.js

？哇！谢谢杰森，你的解释帮我解决了问题@爱德华德沃德很高兴这对你有用
