不同浏览器的 node.js 的 express.io(均在最新版本中)中保存会话的方式以及是否正确保存不同。我该如何解决这种不当行为?
代码:
app.get('/home', function(req, res) {
req.session.variable = 'value';
req.session.save(function() {
console.log(req.session);
});
res.send('<script src="/socket.io/socket.io.js"></script>\
<script>var socket = io.connect();</script>\
Home content');
});
app.io.route('disconnect', function(req) {
console.log('-------------------------------');
console.log(req.session);
req.session.variable = '';
req.session.save(function() {
console.log(req.session);
console.log('-------------------------------');
});
});
情况:我在/home
页面上,我重新加载了页面。重新加载后除 Chrome 之外的每个(?)浏览器中的控制台输出:

在 Chrome 中:

这可能是 Chrome 的错误而不是 express.io 的错误吗?Chrome 中的日志顺序与任何其他浏览器都不同,这也很奇怪。
我需要的是,如果用户离开某个页面(设置该变量),则应该删除/清空会话变量。
