react-native WebSocket & nodejs WebSocket

Question

NodeJS：

const WebSocket = require('ws');
const ws = new WebSocket('wss://siteurl');

ws.on('open', function open() {
    ws.send('');
});

ws.on('message', function incoming(message) {
    console.log(message);
});

反应原生

let connection = new WebSocket('wss://siteurl');

connection.onopen = () => {
            connection.send('');
        };

connection.onmessage = ((event) => {
            console.log(event);
        });

connection.onerror = (event) => {
            console.log(event);
        }

NodeJS 工作正常，但 react-native 返回“无法解析主机”。 Android Stuio 模拟器，以npm run android 开头。

任何想法为什么会发生？

更新：

const socket = new WebSocket('wss://siteurl');
        
        socket.onopen = () => {
            console.log('Socket connected!');
            socket.send('');
        }

        socket.onmessage = (message) => {
            console.log(`Message:\n`, message.data);
        }
    ```
Browser works fine too

你可以使用socket.io-client

socket.io-client Document

• 示例

// ES6 import or TypeScript
import { io } from "socket.io-client";
// CommonJS
const io = require("socket.io-client");

// the following forms are similar
const socket = io("https://server-domain.com");
const socket = io("wss://server-domain.com");
const socket = io("server-domain.com"); // only in the browser when the page is served over https

socket.on('message', (event) => {
        console.log(event);
});
