Question

您是否曾经使用WebSocket（来自'socket.io-client'的SocketIOClient）在React Native应用程序中遇到此消息？...

Unrecognized WebSocket connection option(s) `agent`, `perMessageDeflate`, `pfx`, `key`, `passphrase`, `cert`, `ca`, `ciphers`, `rejectUnauthorized`. Did you mean to put these under `headers`?

Answer 1

是的，这是在Socket.io中的WebSocket类构造函数中发生的。我认为在构造函数中将传输层指定为“ websocket”时会发生这种情况（这对于使用React Native socket io是必需的）。它没有做任何坏事，但是很烦人。您可以使用本机YellowBox.ignoreWarnings摆脱它：启动应用程序时：

console.ignoredYellowBox = ['Remote debugger'];
import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings([
    'Unrecognized WebSocket connection option(s) `agent`, `perMessageDeflate`, `pfx`, `key`, `passphrase`, `cert`, `ca`, `ciphers`, `rejectUnauthorized`. Did you mean to put these under `headers`?'
]);

消除错误的一种方法：

let socket = io.connect(SOCKET_URL, {
  timeout: 10000,
  jsonp: false,
  transports: [‘websocket’],
  autoConnect: false,
  agent: ‘-’,
  path: ‘/’, // Whatever your path is
  pfx: ‘-’,
  key: token, // Using token-based auth.
  passphrase: cookie, // Using cookie auth.
  cert: ‘-’,
  ca: ‘-’,
  ciphers: ‘-’,
  rejectUnauthorized: ‘-’,
  perMessageDeflate: ‘-’
});

无法识别的WebSocket连接选项`agent`，`perMessageDeflate`，`pfx`，`key`，`passphrase ......是要放在“标头”下吗？
