Cocos Creator WebSocket实例：连接、发送与接收数据的实现

Cocos Creator WebSocket实例。

需要注意几个问题：

1、send()发送的数据格式，这里是有要求的。

2、接收到的数据需要进行一个反序列化。

let ws = new WebSocket("ws://192.168.79.2:7070");
ws.onopen = () => {
	console.log("连接成功");
		ws.send("{\"Version\":{ \"Version\": \"v0.0.1\"}}");
	};
	ws.onmessage = (event) => {
	let data = event.data;
	if (typeof data === "string") {
		console.log("Received string data:", data);
	} else if (data instanceof ArrayBuffer) {
		console.log("Received ArrayBuffer data:", data);
 		// 如果你需要将 ArrayBuffer 转换为字节数组，可以这样做：
		const byteArray = new Uint8Array(data);
		console.log("Byte array:", byteArray);
	} else if (data instanceof Blob) {
		console.log("Received Blob data:", data);
		// 如果你需要将 Blob 转换为 ArrayBuffer 或字节数组，可以使用 FileReader
		const reader = new FileReader();
		reader.onload = () => {
			const arrayBuffer = reader.result as ArrayBuffer;
			console.log("ArrayBuffer:", arrayBuffer);
			const byteArray = new Uint8Array(arrayBuffer);
			console.log("Byte array:", byteArray);
			let jsonString = new TextDecoder().decode(byteArray)
			console.log("jsonSt = ",jsonString);
			let data1 = JSON.parse(jsonString);
			console.log("data1 = ",data1);
		};
		reader.readAsArrayBuffer(data);
			} else {
				console.log("Received unknown data type:", data);
			}
		};
		ws.onclose = (event) => {
			console.log(`WebSocket closed: ${event.code} ${event.reason}`);
		};
