Node.js 请帮助我nestjs套接字为什么出错？

因为这个问题，我彻夜未眠。我想我已经尽力了。我们的前端使用https，后端也使用https。目前，api运行良好，但聊天服务器仍在继续抛出ERR_SSL_PROTOCOL_错误

前端是使用我们的聊天室购物：3001/聊天插座。 这个问题似乎可以通过请求shop:3001/聊天来解决，但只会创建一个称为混合内容的新错误

-后端nginx（/etc/nginx/sites available/default）-

-后端main.ts-

import { ValidationPipe } from '@nestjs/common';
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import * as fs from 'fs';
import { NestExpressApplication } from '@nestjs/platform-express';
import { join } from 'path';

async function bootstrap() {
    const httpsOptions = {
        key: fs.readFileSync(
            '/etc/letsencrypt/live/dongmul.shop/privkey.pem',
            'utf8'
        ),
        cert: fs.readFileSync(
            '/etc/letsencrypt/live/dongmul.shop/cert.pem',
            'utf8'
        ),
        ca: fs.readFileSync(
            '/etc/letsencrypt/live/dongmul.shop/chain.pem',
            'utf8'
        )
    };
    const app = await NestFactory.create<NestExpressApplication>(AppModule, {
        cors: true,
        httpsOptions
    });

    app.useStaticAssets(join(__dirname, '..', 'public'));
    app.useGlobalPipes(
        new ValidationPipe({
            whitelist: true,
            forbidNonWhitelisted: true,
            transform: true
        })
    );
    await app.listen(3000);
}
bootstrap();

我解决了这个问题。我刚刚删除了WebSocket网关的端口号。完成此操作后，可以将端口3000与api一起使用。

import { ValidationPipe } from '@nestjs/common';
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import * as fs from 'fs';
import { NestExpressApplication } from '@nestjs/platform-express';
import { join } from 'path';

async function bootstrap() {
    const httpsOptions = {
        key: fs.readFileSync(
            '/etc/letsencrypt/live/dongmul.shop/privkey.pem',
            'utf8'
        ),
        cert: fs.readFileSync(
            '/etc/letsencrypt/live/dongmul.shop/cert.pem',
            'utf8'
        ),
        ca: fs.readFileSync(
            '/etc/letsencrypt/live/dongmul.shop/chain.pem',
            'utf8'
        )
    };
    const app = await NestFactory.create<NestExpressApplication>(AppModule, {
        cors: true,
        httpsOptions
    });

    app.useStaticAssets(join(__dirname, '..', 'public'));
    app.useGlobalPipes(
        new ValidationPipe({

            forbidNonWhitelisted: true,
            transform: true
        })
    );
    await app.listen(3000);
}
bootstrap();
