nginx 过滤相关的referer 和 origin

1. 相关配置如下

        location / {
        
            #set $allow_cors 0;
            ## 判断不为空
            #if ($http_origin) {
            #    set $allow_cors 1;
            #}
            #set $flag 0;
            valid_referers 10.800;
            if ($invalid_referer) {
                set $flag 1;
                return 403 ;
            }

            if ($http_origin !~* "(10.00)"  ) {
                set $flag 1$flag;
                #return 404;
            }
            if ($flag = 11){            
                return 404;
            }
        
            #add_header 'Access-Control-Allow-Origin' $http_origin;
            #add_header 'Access-Control-Allow-Credentials' 'false'  always;

            #add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            #add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';

            #add_header Access-Control-Allow-Origin '*';
            #add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
            #add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
            #add_header Access-Control-Allow-Origin http://10:8096,http://11.42:8094;

            proxy_pass http://11.4:9000/;
        }
