Nginx CORS对于Lumen API无法正常工作

问题描述

嗨，我曾尝试在default.conf文件以及lumen API中启用cors，但由于某些原因，当我尝试在生产chrome中运行angular时，出现CORS错误，这是我的Nginx配置，有人可以告诉我此配置是否是错误的，或者我将CORS add_header放置在错误的位置

        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
    }

}

我不确定100％是否是我在此处发布此问题的地方，所以如果不能，可以有人通知我
