我正在使用快递框架.我想从socket.io访问会话数据.我尝试使用client.listener.server.dynamicViewHelpers数据表达dynamicHelpers,但我无法获取会话数据.有一个简单的方法吗？请参阅代码

app.listen(3000);

var io = require('socket.io');
var io = io.listen(app);

io.on('connection', function(client){
    // I want to use session data here
    client.on('message', function(message){
        // or here
    });
    client.on('disconnect', function(){
        // or here
    }); 
});

如何与Socket.io 1.0和Express 4.x共享会话？我使用Redis商店,但我认为这无关紧要.我知道我必须使用中间件来查看cookie和获取会话,但不知道如何.我搜索但找不到任何工作

    var RedisStore = connectRedis(expressSession);
    var session = expressSession({
        store: new RedisStore({
            client: redisClient
        }),
        secret: mysecret,
        saveUninitialized: true,
        resave: true
    });
    app.use(session);

    io.use(function(socket, next) {
        var handshake = socket.handshake;
        if (handshake.headers.cookie) {
            var str = handshake.headers.cookie;
            next();
        } else {
            next(new Error('Missing Cookies'));
        }
    });

我有一个跨域AJAX GET成功预先通过,但cookie没有附加到GET请求.当用户单击登录按钮时,将进行POST以将用户登录,这可以跨域正常工作.JavaScript是:

        $.ajax(signin_url, {
            type: "POST",
            contentType: "application/json; charset=utf-8",
            data: JSON.stringify(credentials),
            success: function(data, status, xhr) {
                signInSuccess();
            },
            error: function(xhr, status, error) {
                signInFailure();
            },
            beforeSend: function(xhr) {
                xhr.withCredentials = true
            }
        });

响应标头包含一个cookie:

Set-Cookie:user_token=snippysnipsnip; path=/; expires=Wed, 14-Jan-2032 16:16:49 GMT

如果登录成功,则会发出JavaScript GET请求以获取当前用户的详细信息:

function signInSuccess() {
    $.ajax(current_user_url, {
        type: "GET",
        contentType: "application/json; charset=utf-8",
        success: function(data, status, xhr) {
            displayWelcomeMessage();
        },
        beforeSend: function(xhr) {
            xhr.withCredentials = true;
        }
    });
}

从Chrome的OPTIONS请求返回的与CORS相关的标头是:

Access-Control-Allow-Credentials:true
Access-Control-Allow-Headers:X-Requested-With, X-Prototype-Version, Content-Type, Origin, Allow
Access-Control-Allow-Methods:POST, GET, OPTIONS
Access-Control-Allow-Origin:http://192.168.0.5
Access-Control-Max-Age:1728000 …

首先,我想告诉我,我已经阅读了Stack中的所有问题以及与CORS相关的所有问题,但实现仍然无效.我的APP建立在角度crud演示之上:

所以我在app配置中:

$httpProvider.defaults.useXDomain = true;
$httpProvider.defaults.withCredentials = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];

我知道它们设置正确(通过调试).在我的"安全"应用程序中,我正在请求当前用户,跨域:

return $http.get(LAYOUT_CONFIG.baseURL + '/current-user').then(function(response) {
      //service.currentUser = response.data.user;
      service.currentUser = response.data;
      return service.currentUser;
    });

我在第一次请求时得到这些标题:

    Access-Control-Allow-Credentials:true
Access-Control-Allow-Headers:accept, origin, content-type, cookie
Access-Control-Allow-Methods:GET,POST
Access-Control-Allow-Origin:http://admin.vibetrace.com
Access-Control-Max-Age:1728000
Connection:keep-alive
Content-Encoding:gzip
Content-Type:text/html; charset=utf-8

所以Set-Cookie就在那里.但是,后续的$ http.get请求(来自angular)不会发送应该先前已设置的cookie.
