Question

我有这个网络TCP服务器：

private startTCPServer() {
    const socket = net.createServer(function(socket_object){
        socket_object.on("data", (data) => {
            console.log(data);
        });
        socket_object.on("end", socket_object.end);
        socket_object.on("error", (err: any) => {
            console.log(err);
        });
    });
    socket.listen(this.TCP_PORT, this.ADDRESS, () => {
        console.log('listening...');
    });
}

如何在达到"data"事件时获取连接到此服务器的客户端的IP？

Answer 1

您的connectListener（授予createServer的功能）获取socket_object，它是net.Socket类型的对象。有一个属性remoteAddress，它具有远程主机的地址。

Answer 2

为了补充，例如，如果你想在remoteAddress事件中使用"data"，请执行以下操作：

private startTCPServer() {
    const wrapper = (remoteAddress: string) => {
        return (data: any) => {
            console.log(data, remoteAddress);
        }
    };
    const socket = net.createServer(function(socket_object){
        socket_object.on("data", wrapper(socket_object.remoteAddress));
        socket_object.on("end", socket_object.end);
        socket_object.on("error", (err: any) => {
            console.log(err);
        });
    });
    socket.listen(this.TCP_PORT, this.ADDRESS, () => {
        console.log('listening...');
    });
}
