无法识别的WebSocket连接选项`agent`，`perMessageDeflate`，`pfx`，`key`，`passphrase`...你的意思是把这些放在“标题”下面吗？

Question

您是否曾经在使用WebSocket (来自‘Socket.IO-client’的SocketIOClient )的React Native应用程序中遇到过此消息？

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

Answer 1

消除错误的一种方法是：

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: ‘-’
});

Answer 2

是的，这发生在Socket.io的WebSocket类构造函数中。我认为当你在构造函数中指定你的传输层为'websocket‘时(这是使用React Native socket io所必需的)，就会发生这种情况。它不会做任何坏事，但很烦人。您可以使用react-native YellowBox.ignoreWarnings：在启动您的应用程序时摆脱它：

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`?'
]);
