Question

我使用的是express-socket.io-session模块https://github.com/oskosk/express-socket.io-session

我可以在socket.handshake上看到会话数据

  }
}

socket.handshake.session没有会话数据。我不清楚如何从socket.handshake.sessionStore

中提取会话数据

Answer 1

就会话数据而言，其JSON表示为字符串。您可以迭代根对象中的键并解析每个键的值。

var keys = Object.keys(socket.handshake.sessionStore.sessions);
keys.forEach(function(key) {

    // extract string into a json object   
    var sessionObject = JSON.parse(socket.handshake.sessionStore.sessions[key]);

});

express-socket.io-session会话变量不可用
