nodejs網絡客戶端套接字重新連接

Question

var socket = new net.Socket();
socket.connect(PORT, HOST, function() {
    console.log("SOCKET CONNECTED TO: " + HOST + ":" + PORT);
    socket.write("Hello World!");
});
socket.on("error", function() {}); // need this line so it wont throw exception

// Add a "close" event handler for the client socket
socket.on("close", function() {
    console.log("Connection lost. How do I reconnect? setTimeout?");
});

失敗后如何重新連接？ 現在，如果連接不成功，一切都會停止。

我嘗試在關閉事件中使用setTimeout，但是當套接字連接時，會多次觸發“ connect”事件。

您可以通過以下方式實現重新連接，同時保持事件綁定：

function connect() {
    var socket = new net.Socket();
        socket.connect(PORT, HOST, function() {
            console.log('SCOEKT CONNECTED TO: ' + HOST + ':' + PORT);
            socket.write('Hello World!');
        });

    socket.on('error', function() {}); // need this line so it wont throw exception

    // Add a 'close' event handler for the client socket
    socket.on('close', function() {
        connect();
    });
}
connect();
