找出哪個環節有 Promise 沒有處理好, 看起來會是 websocket 的東西。

const CQWebsocket = require('../..')

const bot = new CQWebsocket()

bot.on('socket.connecting', function (wsType, attempts) {
  console.log('[%s] 嘗試第 %d 次連線 _(:з」∠)_', wsType, attempts)
}).on('socket.connect', function (wsType, sock, attempts) {
  console.log('[%s] 第 %d 次連線嘗試成功 ヽ(✿ﾟ▽ﾟ)ノ', wsType, attempts)
}).on('socket.failed', function (wsType, attempts) {
  console.log('[%s] 第 %d 次連線嘗試失敗 。･ﾟ･(つд`ﾟ)･ﾟ･', wsType, attempts)
})

bot.connect()

結果是我自己的問題...

拋出 Promise 錯誤, 是預期的行為
此行為乃默認 socket.error 監聽器所為。

添加以下監聽器可以修正。

bot.on('socket.error', function (wsType, err) {
  console.log('[%s] 錯誤: %O', wsType, err)
})

已增加 socket.error 發生時的錯誤提醒, 訊息如下

You should listen on "socket.error" yourself to avoid those unhandled promise warnings.
