webman/cors 跨域问题

问题描述

在 webman 里安装了 composer require webman/cors ，

cors.php 文件内容如下

<?php
namespace Webman\Cors;

use Webman\MiddlewareInterface;
use Webman\Http\Response;
use Webman\Http\Request;

class CORS implements MiddlewareInterface
{
    public function process(Request $request, callable $next) : Response
    {
        $response = $request->method() == 'OPTIONS' ? response('') : $next($request);
        $response->withHeaders([
            'Access-Control-Allow-Credentials' => 'true',
            'Access-Control-Allow-Origin' => $request->header('origin', '*'),
            'Access-Control-Allow-Methods' => $request->header('access-control-request-method', '*'),
            'Access-Control-Allow-Headers' => $request->header('access-control-request-headers', '*'),
        ]);

        return $response;
    }
}

但是为什么还有跨域的问题？
Access to XMLHttpRequest at 'http:// index.html#/:hxcapi.beetang.cn:8787/api/v1/bannerinfo/sts' from origin 'http://127.0.0.1:5501' has beenblocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values 'http://1270.0.1:5501, http://127.0.0.1:5501 , but only one isallowed.

请教大神们，如何设置？
