我使用–with-http_geoip_module来识别流量.有些页面我只想让某个国家/地区访问.这是配置：

对于http

 http{
    geoip_country  /usr/share/GeoIP/GeoIP.dat; # the country IP database
    map $geoip_country_code $allowed_country {
            default 0;
            US 1;
            UK 1;
            HK 1; 
     }
  }

位置指令：

location = /testing {
            if ($allowed_country = 0) {
                    return 301 ;
              }
    }

问题是当我使用美国/香港IP时,我收到404错误.我做错了什么？

UPDATE

这是我完整的conf文件：

http {
include       /etc/Nginx/mime.types;
default_type  application/octet-stream;
log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';
access_log  /var/log/Nginx/access.log  main;
geoip_country  /usr/share/GeoIP/GeoIP.dat; # the country IP database
map $geoip_country_code $allowed_country {
        default 0;
        US 1;
        UK 1;
        HK 1; 
 }
sendfile        on;
#tcp_nopush     on;
#keepalive_timeout  0;
keepalive_timeout  65;
#gzip  on;
index   index.html index.htm;
# Load modular configuration files from the /etc/Nginx/conf.d directory.

include /etc/Nginx/conf.d/*.conf;
server {
    listen       80 default_server;
    server_name  localhost;
    root         /var/www/html;
    include /etc/Nginx/default.d/*.conf;
    location / {
        index index.PHP index.cgi index.pl index.html index.xhtml index.htm index.shtml;
        try_files $uri $uri/ /index.PHP?$args;
    }
    # redirect server error pages to the static page /40x.html
    #
    error_page  404              /404.html;
    location = /40x.html {
    }
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
    }
    #ban specifc country
    location = /testing {
        if ($allowed_country = 0) {
                return 301 ;
          }
     }
    location ~ \.PHP${
        ### SET GEOIP Variables ###
        fastcgi_param GEOIP_COUNTRY_CODE $geoip_country_code;
        fastcgi_param GEOIP_COUNTRY_CODE3 $geoip_country_code3;
        fastcgi_param GEOIP_COUNTRY_NAME $geoip_country_name;
        fastcgi_split_path_info ^(.+?\.PHP)(/.*)$;
        if (!-f $document_root$fastcgi_script_name) {
        return 404;
        }
            try_files $uri $uri/ /index.PHP?$args;
        fastcgi_pass unix:/run/PHP-fpm/PHP-fpm.sock;
            fastcgi_index index.PHP;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi.conf;
            include conf/site.conf;
    } 
}
 }

基本上我只想访问美国,英国和香港的访问/测试页面.
