（注意：这只发生在标记--release上）*

问题

我最近构建了一个基于套接字连接的ionic应用程序，当我处于调试模式时一切正常。然而，当我移动到release（--release属性）时，应用程序不再连接到api端点。套接字正在显示以下消息xhr poll error

预期会发生什么？

连接到API端点。

到底发生了什么？

不连接到API端点。

看起来在Android API级别28之后，你不能使用443以外的任何其他端口进行安全连接...因为它只会在Relase模式下限制你的访问，所以我把我的套接字端口从我原来的改为443，它工作正常。

我也遇到了同样的问题，无法在生产应用上运行（只能在模拟器的开发模式下运行）。无论是端口443还是其他端口。我使用的是自签名证书，但在服务器端和客户端都是rejectUnauthorized: false。
服务器：

import { createSecureServer } from "http2";
import { Server } from "socket.io";
import fs from 'fs';

console.log("Start Server..");

var options = {
    key: fs.readFileSync('./zefau-key.pem', 'utf-8'),
    cert: fs.readFileSync('./zefau-crt.pem', 'utf-8'),
    'allowHTTP1': true,
    requestCert: false,
    rejectUnauthorized: false
}

const httpsServer = createSecureServer(options);
const io = new Server({
    // options
        'cors': {
            'origin': (origin, fn) => {
                return fn(null, origin);
            }
        }
});

// attach server to socket
io.attach(httpsServer);

// error
io.on('error', error => {
    console.error(error);
});

// connection
io.on("connection", (socket) => {
    console.log(socket.id);
    
    socket.on("message", (message) => {
        console.log('message received: ' + message);
        socket.emit('message', 'hi back');
    });
    
});

httpsServer.listen(443, '0.0.0.0');

客户Cordova应用程序（应用程序版本仅用于测试）

<template>
  <router-view />
</template>

<script>
import { defineComponent } from 'vue'
import { io } from "socket.io-client";

export default defineComponent({
  name: 'App',
  
    created() {
        alert("Start Client..");
        
        const URL = "192.168.178.50";
        const socket = io('https://' + URL + ':443', { rejectUnauthorized: false });
        
        socket.on("connect", () => {
            alert("CONNECTED socketio");
            socket.emit('message', 'hi');
        });
        
        socket.on("connect_error", error => {
            alert("CONNECT ERROR (" + URL + "): " + error.message);
        });

        socket.on("message", message => {
            alert('socket message received: ' + message);
        });
    }
})
</script>

我必须配置什么才能让它在Android上的生产应用程序上运行？
