useWebSocket的onOpen问题

[songrunyu926]

在调用onOpen方法时，使用sendMessage失败 发现在onOpen中readyState 状态还是 connecting 0的状态

Hi, songrunyu926.

It seems that this issue is a bit vague and lacks some necessary information.

看起来这条 issue 描述得有些模糊，缺少一些必要的信息。

有 demo 么？

[songrunyu926]

// 在onOpen方法中直接使用sendMessage会有问题 加上定时就好了

const { readyState, sendMessage, latestMessage, connect } = useWebSocket(url, {
    onOpen(event, instance) {
      console.log(readyState)  // 0
      sendMessage(JSON.stringify({ socketType: 0, message: 'keep-alive' }))
      setInterval(() => {
        sendMessage(JSON.stringify({ socketType: 0, message: 'keep-alive' }))
      }, 15000)
    },
    manual: true,
  })

我也遇到这个问题

[aioros2016]

这个问题我也遇到了，在首次连接socket成功后，调用disconnect方法断开连接，然后调用connect方法重新连接。此时，onpen回调中的readyState为0。可能是该hook中的某个异步环节的处理出现了问题。

2022年就提出来了 到现在也没改
明显是个bug 状态还是0的时候就触发了 onOpen了

我也遇到这个问题，连接断开后重新连接，readyState 为1 ，但是报错：
chunk-VGGCA2L5.js?v=27dc857d:16670 Uncaught InvalidStateError: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state.

代码如下：

const ReadyState = {
    Connecting: 0,
    Open: 1,
    Closing: 2,
    Closed: 3
};
const { readyState, sendMessage, latestMessage } = useWebSocket(url);

useEffect(() => {
	switch (readyState) {
		// 连接成功
		case ReadyState.Open:
			sendMessage('data');
			break;
		default:
			break;
	}
}, [readyState, sendMessage]);
