Question

我正在使用快递js。我想访问server.js中的其他文件js函数。请任何人帮助我。

server.js

 var express = require('express'),
 path = require('path'),
 cors = require('cors'),
 bodyParser = require('body-parser'),
 routes = require('#######'), //web routes
 connection = require("######"); //mongodb connection
 authChecker = require("./###/authChecker");

 var app = express();
 app.use(bodyParser.json());
 app.use(express.static(path.join(__dirname, 'app')));
 app.use(express.static('node_modules'));
 app.use(cors());
 app.use(authChecker);
 app.use('/', routes);

我的authChecker js文件是

authChecker.js

module.exports = {
function(req, res, next) {
    console.log("authondication checker process");
    if (req.session.auth || req.path === '/auth') {
        next();
    } else {
        res.redirect("/auth");
    }
}
}

当app.use（authChecker）执行此行时，会在服务器启动时显示此错误。

 E:\MEAN_STACK\MySampAps\Crud_samp\node_modules\express\lib\application.js:210
throw new TypeError('app.use() requires middleware functions');
^

TypeError: app.use() requires middleware functions
at Function.use (E:\MEAN_STACK\MySampAps\Crud_samp\node_modules\express\lib\application.js:210:11)
at Object.<anonymous> (E:\MEAN_STACK\MySampAps\Crud_samp\server.js:39:5)
at Module._compile (module.js:569:30)
at Object.Module._extensions..js (module.js:580:10)
at Module.load (module.js:503:32)

您可以将 authChecker.js 修改为：

module.exports = function(req, res, next) {
console.log("authondication checker process");
if (req.session.auth || req.path === '/auth') {
    next();
} else {
    res.redirect("/auth");
}}

然后你可以在 server.js 中调用该函数：app.use(authChecker)

希望这有帮助

检查一下 server.js

var express = require('express'),
 path = require('path'),
 cors = require('cors'),
 bodyParser = require('body-parser'),
 routes = require('#######'), //web routes
 connection = require("######"); //mongodb connection
 authChecker = require("./###/authChecker").auth;

 var app = express();
 app.use(bodyParser.json());
 app.use(express.static(path.join(__dirname, 'app')));
 app.use(express.static('node_modules'));
 app.use(cors());
 app.use(authChecker);
 app.use('/', routes);

我的authChecker js文件是

authChecker.js

module.exports = {
auth:function(req, res, next) {
    console.log("authondication checker process");
    if (req.session.auth || req.path === '/auth') {
        next();
    } else {
        res.redirect("/auth");
    }
}
}

如何在server.js文件中调用其他js函数？
