代理转发在 Nginx、Laravel、弹性负载均衡器上不起作用

我有一个 AWS 弹性负载均衡器，它接收域 (bunny.misite.dev) 的 https 请求，请求通过 http 发送到服务器 Nginx，Laravel 应用程序回答请求。

我遇到的问题是 Laravel 没有将请求识别为 Https，而是将请求识别为 http。

为了解决这个问题，Laravel 提供了一个我使用过的“可信代理”中间件：

<?php

namespace App\Http\Middleware;

use Fideloper\Proxy\TrustProxies as Middleware;
use Illuminate\Http\Request;

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array|string|null
     */
    protected $proxies = '*';

    /**
     * The headers that should be used to detect proxies.
     *
     * @var int
     */
    protected $headers = Request::HEADER_X_FORWARDED_FOR |
        Request::HEADER_X_FORWARDED_HOST |
        Request::HEADER_X_FORWARDED_PORT |
        Request::HEADER_X_FORWARDED_PROTO |
        Request::HEADER_X_FORWARDED_AWS_ELB;
}

我的 nginx 配置是

server {
    listen                  80 ;
    listen                  [::]:80 ;

    server_name             bunny.misite.dev;
