我得到cors问题在我正在工作的一个Poc.后端API是背后的Nginx代理服务器，如果任何试图击中代理，浏览器是抱怨Cors问题.
如果我尝试使用API服务的实际端点，我没有看到任何错误.我假设，我必须在Nginx级别解决这个问题，而不是在react应用程序级别添加代理配置.我已经尝试了在线论坛中提供的大多数解决方案.如果我错过了任何纠正错误的东西，请任何人帮助我.
React应用运行在3000端口，Nginx运行在80端口。

Default.conf中的代理设置

    listen 80;
    server_name  localhost;
    resolver 127.0.0.11 valid=1s ipv6=off;

    location /products/ {

                add_header "Access-Control-Allow-Headers" "Origin, X-Requested-With, Content-Type, Accept";
                add_header 'Access-Control-Allow-Credentials' 'true';
            if ($request_method = 'OPTIONS') {
               return 204;   
            }   proxy_set_header Host $host;

            add_header 'Access-Control-Allow-Credentials' 'true';
