access-control-allow-origin跨域添加多个域名

以nginx为例：

location /fonts {
    # this will echo back the origin header
    if ($http_origin ~ "168itw.com$") {
        add_header "Access-Control-Allow-Origin" $http_origin;
    }
}

或者：

location / {
    if ($http_origin ~* "^https?://(168itw.com|www.168itw.com)$") {
        add_header Access-Control-Allow-Origin "$http_origin";
    }
}
