問題描述

webman-admin 打包之后出現(xiàn)跨域問題，服務(wù)端用的nginx代理，按照手冊上設(shè)置的，Nginx也配置了跨域，前端請求的時候，還會提示跨域錯誤

程序代碼

nginx配置

upstream webman {
    server 172.31.34.153:8787;
    keepalive 10240;
}
server {
  listen 8989;
  listen [::]:8989;
  server_name IP:8989;
  access_log off;
  index index.html index.htm index.php;
  root /data/wwwroot/IP:8787;

  include /usr/local/nginx/conf/rewrite/none.conf;
  #error_page 404 /404.html;
  #error_page 502 /502.html;

  location / {

      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Access-Control-Allow-Headers' '*';
      add_header 'Access-Control-Allow-Methods' '*';
      add_header 'Access-Control-Max-Age' 86400;

      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header Host $host;
      proxy_http_version 1.1;
      proxy_set_header Connection "";
      if (!-f $request_filename){
          proxy_pass http://webman;
      }
  }
}

webman跨域中間件

<?php
namespace app\middleware;

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

class AccessControl implements MiddlewareInterface
{
    public function process(Request $request, callable $handler) : Response
    {
        // 如果是opitons請求則返回一個空的響應(yīng)，否則繼續(xù)向洋蔥芯穿越，并得到一個響應(yīng)
        $response = $request->method() == 'OPTIONS' ? response('') : $handler($request);

        // 給響應(yīng)添加跨域相關(guān)的http頭
        $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;
    }
}

報錯信息

Access to XMLHttpRequest at 'http://ip:8989/api/sport/1?pageSize=20&page=1&type=1' from origin 'http://ip' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

操作系統(tǒng)及workerman/webman等框架組件具體版本
