nodejs express-session 中间件在 Visual Studio 中不起作用

Question

我正在尝试在 nodejs express 中使用 express-session，但我无法设置或获取会话。我在尝试构建时收到“类型‘请求’上不存在属性‘会话’”。

我试图更改代码的顺序，但没有任何效果

节点版本：v10.15.3

app.ts

  var app = express();
  var bodyParser = require('body-parser');
  var session = require('express-session');
  var FileStore = require('session-file-store')(session);

  app.use(bodyParser.urlencoded({extended: true})); 
  app.use(bodyParser.json());       // to support JSON-encoded bodies
  app.use(express.json());       // to support JSON-encoded bodies
  app.use(express.urlencoded({ extended: true })); // to support URL-encoded   bodies
  app.use(session({
      name: 'test-session-cookie-id',
      secret: 'test',
      resave: true,
      store: new FileStore(),
      saveUninitialized: true,
      cookie: { secure: true }
  }));
  // view engine setup
  app.set('views', path.join(__dirname, 'views'));
  app.set('view engine', 'pug');

  app.use(express.static(path.join(__dirname, 'public')));


  app.use('/', routes);
  app.use('/users', users);
  app.use('/signup', signup);
  app.use('/verify', verify);

  app.use(function printSession(req, res, next) {
    console.log('req.session', req.session); //error
    return next();
  });

更新：

module 本身似乎工作正常。它创建了一个包含 500 多个文件的会话文件夹，这很奇怪

更新2：

快速会话工作正常，但错误困扰着我。我卸载了vs2017并安装了vs2019并更新了打字稿但问题仍然存在

Answer 1

我的 dependencies/devDependencies 中没有 @types/express-session 。 npm install --save @types/express-session 完成了这项工作。现在没有错误
