socket.io中的set和get方法没有了，是什么情况
补充：安装[email protected]版本，1.0版本中去掉了get和set方法，外加一个：nodejs + socket.io + redis 新手上路：http://www.cnblogs.com/aibo/p/3366925.html
自问自答吧，找到答案了，在官方文档里，被《nodejs高级编程》这本书坑了啊，都过时了。。：
The old io.set() and io.get() methods are deprecated and only supported for backwards compatibility. Here is a translation of an old authorization example into middleware-style.
io.set('authorization’, function (handshakeData, callback) { // make sure the handshake data looks good callback(null, true); // error first, ‘authorized’ boolean second }); vs.
io.use(function(socket, next) { var handshakeData = socket.request; // make sure the handshake data looks good as before // if error do this: // next(new Error(‘not authorized’); // else just call next next(); });
