我试图实现无限滚动。在我的第一个路径中,我从数据库中加载了5个元素,并存储了上次看到的项目的ID。要加载更多数据,调用getNextHomeContent,但由于某种原因,req.session.lastseen未定义。
server.js
[('x1_idx_enc_a', 0.13874401585637453),
('x1_idx_enc_c', 0.23498565469334595),
('x2_idx_enc_foo', -0.083558932128022873),
('x3', 0.0030186112903237442),
('x4', -0.12951394186593695)]
这是我在 homeCtrl.js
中的路线控制器var express = require('express');
var session = require('express-session');
var app = express();
var mongoose = require('mongoose');
var logger = require('morgan');
var bodyParser = require('body-parser');
var cors = require('cors');
//imports database configuration
var databaseConfig = require('./config/database');
//defines route file to use
var router = require('./app/routes');
//connect to datbase
mongoose.connect(databaseConfig.url);
app.listen(process.env.PORT || 8080);
console.log("App listening on port 8080");
app.use(bodyParser.urlencoded({ extended: false })); // Parses urlencoded bodies
app.use(bodyParser.json()); // Send JSON responses
app.use(logger('dev')); // Log requests to API using morgan
app.use(cors());
app.use(session({
resave: true,
saveUninitialized: true,
secret: 'keyboard cat',
cookie: {
maxAge: 60000,
secure: false
}
}));
router(app);
当获取Home内容时,req.session.lastname将设置为最后一项的ID。但是,当getNextHomeContent()运行时,req.session.lastitem将变为未定义。任何人都可以帮我这个吗?
谢谢!
