Question

我有一个本地运行的UI，在这里我将远程资源称为arg.kl.com。我将UI托管在具有以下配置的nginx容器上。但是我仍然在浏览器控制台中收到上述警告。不确定此配置有什么问题。

server {
listen 80;
server_name localhost;

add_header 'Access-Control-Allow-Origin' $http_origin;
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';

location / {
    root   /usr/share/nginx/html;
    index  index.html index.htm;
    add_header 'Access-Control-Allow-Origin' $http_origin;
    add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
}

location /folders/ {

    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    add_header 'Access-Control-Allow-Origin' $http_origin;
    proxy_set_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
    proxy_pass arg.kl.com;
}

}

我在控制台中看到以下错误：

跨源请求被阻止：同源策略禁止阅读位于的远程资源 http://arg.kl.com:4010/layouts/MV672Scse0-8663-40d8-876d-f.mvhtml。（原因：CORS标头中缺少令牌“ access-control-allow-headers” CORS飞行前频道中的“ Access-Control-Allow-Headers”。

这是怎么了？

由于缺少CORS标头“ Access-Control-Allow-Headers”，跨域请求被阻止
