无法在 Express Route 中间件中设置会话属性

Question

我目前正在使用 NodeJS 和 Express 开发 API。

var express = require('express');
var app = express.createServer();

app.configure(function() {
  app.use(express.cookieParser());
  app.use(express.session({ secret:"aaa"}));

});



function tokenLogin (req, res) {
    req.sesssion.uid = 1;
}
app.get('/api/news/:inbox', tokenLogin, function(req, res) {

});
app.listen(3000);
console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);

当我调用路由 /api/news/1 时，控制台显示 TypeError： <代码>

TypeError: Cannot set property 'uid' of undefined

这是我的代码中的错误还是 ExpressJS 的错误？

Answer 1

req.sesssion 是一个拼写错误。您需要req.session。
