JavaScript WebSocket链接和控制台测试

有一个免费的WebSocket服务，你发什么，他回显什么。

wss://echo.websocket.events

const socket = new WebSocket("wss://echo.websocket.events");

socket.onopen = () => {
  socket.send("Hello WebSocket!");
};

socket.onmessage = (event) => {
  console.log("WebSocket: ", event.data);
};

socket.onerror = (error) => {};

socket.onclose = () => {};

当然，也可以控制台进行测试，

npm install wscat -g

wscat -c wss://echo.websocket.events

net.cctv3.i@StationChnqoo ~ % wscat -c wss://echo.websocket.events
