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);
};
