节点抛出TypeError：无法读取未定义的属性'indexOf'
不确定，但我认为我有一些工作，但它没有，我得到的错误是相当无益的。
所以，试图发送护照对象的路线之一，我明白应该只是设置
var users = require('./routes/users')(app, passport); 这在启动时会引发故障

如果我删除应用程序和护照，问题就会神奇地消失。 ./routes/users中的path不会使用它们中的任何一个。
我已经添加了一些代码（删除了一些好的forms的护照configuration）
var express = require('express'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var mongoose = require('mongoose'); var methodOverride = require('method-override'); // simulate DELETE and PUT (express4) var stylus = require('stylus'); var nib = require('nib'); var morgan = require('morgan'); // express session and passport var session = require('express-session'); var passport = require('passport'); var flash = require('connect-flash'); var app = express(); function compile(str, path) { return stylus(str) .set('filename', path) .use(nib()) } // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'jade'); var accesslevels = require('./config/accesslevels.js'); console.log("Test something " + accesslevels.userRoles.user); // required for passport app.use(session({ secret: '' + 'asifIwouldtellstackoverflowright', resave: true, saveUninitialized: true })); // session secret app.use(passport.initialize()); app.use(passport.session()); // persistent login sessions app.use(flash()); // use connect-flash for flash messages stored in session //Routes after passports var routes = require('./routes/index'); var users = require('./routes/users')(app, passport); var loginsrv = require('./routes/login'); var api = require('./routes/api'); var partials = require('./routes/partials'); var auth = function(req, res, next) { if (!req.isAuthenticated()) res.send(401); else next(); }; //See more at: https://vickev.com/#!/article/authentication-in-single-page-applications-node-js-passportjs-angularjs // uncomment after placing your favicon in /public //app.use(favicon(__dirname + '/public/favicon.ico')); app.use(logger('dev')); app.use(bodyParser.json()); // get information from html forms app.use(bodyParser.urlencoded({ extended: true })); app.use(cookieParser()); app.use(require('stylus').middleware(path.join(__dirname, 'public'))); app.use(express.static(path.join(__dirname, 'public'))); app.use('/', routes); app.use('/users', users); app.use('/partials', partials); app.use('/loginsrv', loginsrv); //app.use(accesslevels()); //console.log(accesslevels); // catch 404 and forward to error handler app.use(function(req, res, next) { var err = new Error('Not Found'); err.status = 404; next(err); }); // error handlers // development error handler // will print stacktrace if (app.get('env') === 'development') { app.use(function(err, req, res, next) { res.status(err.status || 500); res.render('error', { message: err.message, error: err }); }); } // production error handler // no stacktraces leaked to user app.use(function(err, req, res, next) { res.status(err.status || 500); res.render('error', { message: err.message, error: {} }); }); module.exports = app; app.listen(30010);
编辑：添加routes / users.js
var express = require('express'); var router = express.Router(); /* GET users listing. */ router.get('/', function(req, res, next) { res.send('respond with a resource'); }); /* // route to test if the user is logged in or not router.get('/loggedin', function(req, res) { res.send(req.isAuthenticated() ? req.user : '0'); }); router.post('/login', passport.authenticate('local'), function(req, res) { res.send(req.user); }); router.post('/logout', function(req, res){ req.logOut(); res.send(200); }); */ module.exports = router;
在上面的代码中，我用router.get('/', function(app, passport, req, res, next)改变了原来的router.get('/', function(req, res, next) 。
以防万一，如果你有任何HTTP动词路线app.get（'/'…）在app.use（..）之后使用，那么你将在Express4x中得到这个错误。
在这里参考
我不知道为什么，但诀窍是用router.get('/', function(app, passport, req, res, next) router.get('/', function(req, res, next)更改原始的router.get('/', function(req, res, next) router.get('/', function(app, passport, req, res, next)解决了这个问题，不知道为什么express需要一个不使用传递对象的函数来获得护照和应用程序，但似乎是这样。
var express = require('express'); var router = express.Router(); /* GET users listing. */ router.get('/', function(app,passport, req, res, next) { res.send('respond with a resource'); }); /* // route to test if the user is logged in or not router.get('/loggedin', function(req, res) { res.send(req.isAuthenticated() ? req.user : '0'); }); router.post('/login', passport.authenticate('local'), function(req, res) { res.send(req.user); }); router.post('/logout', function(req, res){ req.logOut(); res.send(200); }); */ module.exports = router;
app.get('/api',function(req,res) { if (req.url.indexOf('/api')==0) { console.log('yes i have done it'); } });
我已经实现了这一点，我在控制台上得到输出。在你的代码中发生了什么是req是undefined.So节点抛出这个错误…正如你可以在我的代码中看到，我们只能使用req.url。 indexOf方法只有当我们在需求的范围（即你必须声明search里面的函数callback处理请求，水库…..）
