如何从 nodeJS 服务器读取套接字 IO 连接负载

Question

当从 swift 客户端初始化套接字连接时，有一个带有有效负载的发送方法，我用它来发送 uid 作为有效负载

socket.connect(withPayload: ["uid": uid])

然而，当从 nodeJS 服务器接收到连接事件时，我似乎无法访问此有效载荷

io.on('connection', socket => {
    console.log("received connection", socket.request); 
    // Request does not include my payload
});

Answer 1

刚遇到同样的问题。打印出整个套接字显示它存储在

auth

变量中。这应该有效：

io.on('connection', socket => {
    const payload = socket.handshake.auth
    const uid = payload["uid"]
}
