websockets的bufferedAmount使用范例代码
// 10k max buffer size. var THRESHOLD = 10240; // Create a New WebSocket connection var ws = new WebSocket("ws://w3mentor.com"); // Listen for the opening event ws.onopen = function () { // Attempt to send update every second. setInterval( function() { // Send only if the buffer is not full if (ws.bufferedAmount < THRESHOLD) { ws.send(getApplicationState()); } }, 1000); };
