我是 react native 的新手，目前，我正在研究 react native 移动应用程序 WebSocket 创建。我能够成功地在反应应用程序中成功创建 WebSocket 连接并接收到消息。但是在本机反应中，onConnect不起作用。

这是 package.json 中 stompjs 的版本

"@stomp/stompjs": "6.1.2",

这是我在 react 和 react native 中使用的代码。

import {Client} from "@stomp/stompjs";


            stompClient = new Client();

            stompClient.configure({
                brokerURL: 'ws://192.168.xx.xx:8080/ws',
                connectHeaders: {
                    login: 'guest',
                    passcode: 'guest',
                    accessToken: access_token, //variables
                    appKey: app_key //variables
                },
                reconnectDelay: 2000,
                heartbeatIncoming: 0,
                heartbeatOutgoing: 20000,
                onConnect: () => {
                    console.log("On connect");
                    stompClient.subscribe('/topic/public/my_topic', (message) => {
                         console.log("message");
                         Alert.alert("Connected", "Connected");
                    }, {appKey: app_key});
                },
                onStompError: (frame) => {
                    console.log('Broker reported error: ' + frame.headers['message']);
                    console.log('Additional details: ' + frame.body);
                },
                onDisconnect: (frame) => {
                    console.log("Stomp Disconnect", frame);
                },
                onWebSocketClose: (frame) => {
                    console.log("Stomp WebSocket Closed", frame);
                },
                debug: (str) => {
                    console.log(new Date(), str);
                },
                onUnhandledMessage: (msg) => {
                    console.log(msg);
                }
            });

            stompClient.activate();

这是我在 react-native 调试器的控制台中得到的回复。
