Question

在我的app.js中我有：

var express       = require('express')
var path          = require('path');
var logger        = require('morgan');
var cookieParser  = require('cookie-parser');
var bodyParser    = require('body-parser');
var passport      = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var mongo         = require('mongodb');
var flash         = require('connect-flash');
....
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser('3mKay'));
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.session({ secret: 'thisISmyS3cR3t'}));

这在Heroku中与以下消息崩溃。

 Error: Most middleware (like session) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.

我跑了，所以它确实存在于package.json文件中：

 npm install express-sessions --save

"dependencies": {
....
"express": "~4.8.6",
"express-session": "^1.8.1",
"passport": "^0.2.1",
"passport-local": "^1.0.0",
....

当我注释掉

时，它工作正常

app.use(express.session({ secret: 'thisISmyS3cR3t'}));

我也尝试了以上的变体，但它给出了相同的错误信息。可能导致这种情况发生的任何想法？我可能忽视的东西......

安装后，您必须在代码中实际使用它：

var express       = require('express');
var session       = require('express-session');
var path          = require('path');
var logger        = require('morgan');
var cookieParser  = require('cookie-parser');
var bodyParser    = require('body-parser');
var passport      = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var mongo         = require('mongodb');
var flash         = require('connect-flash');
....
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser('3mKay'));
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(session({ secret: 'thisISmyS3cR3t'}));

无法在heroku nodejs app中使用快速会话
