Django 无法检测到来自 nginx 的 GeoIP 数据

Question

我正在尝试从访问我网站的人那里获取 country_code，我决定使用nginx geoIP 模块来执行此操作。我已经设置了nginx 配置等。但不知何故，它总是不断给出空值。当我使用nginx -V 时，nginx 具有--with-http_geoip_module，所以它的GeoIP 函数应该可以工作。我使用uwsgi 作为我的django。

我已经安装了 geoIP 数据：

cd /etc/nginx/geoip
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
gunzip GeoIP.dat.gz
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gunzip GeoLiteCity.dat.gz

这是我的 nginx.conf：

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
    worker_connections 768;
    # multi_accept on;
}

http {
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 210;
    types_hash_max_size 2048;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    geoip_country /etc/nginx/geoip/GeoIP.dat; # the country IP database
    geoip_city /etc/nginx/geoip/GeoLiteCity.dat; # the city IP database

    proxy_set_header GEOIP_COUNTRY_CODE $geoip_country_code;
    proxy_set_header GEOIP_COUNTRY_CODE3 $geoip_country_code3;
    proxy_set_header GEOIP_COUNTRY_NAME $geoip_country_name;
    proxy_set_header GEOIP_CITY_COUNTRY_CODE $geoip_city_country_code;
    proxy_set_header GEOIP_CITY_COUNTRY_CODE3 $geoip_city_country_code3;

    proxy_set_header GEOIP_POSTAL_CODE $geoip_postal_code;
    proxy_set_header GEOIP_CITY_CONTINENT_CODE $geoip_city_continent_code;
    proxy_set_header GEOIP_LATITUDE $geoip_latitude;
    proxy_set_header GEOIP_LONGITUDE $geoip_longitude;

    gzip on;
    gzip_disable "msie6";

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

这是我的 /etc/nginx/sites-available：

server {
listen 80;
listen [::]:80;

index index.html index.htm index.nginx-debian.html;

server_name www.testname.com testname.com;

error_log  /var/www/log_nginx/error.log;   
gzip on;
gzip_disable "msie6";

proxy_send_timeout      180s;
proxy_read_timeout      180s;

}

location / {
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header HTTP_X_GEOIP_COUNTRY $geoip_country_name;
    proxy_set_header HTTP_X_GEOIP_CITY    $geoip_city;
    include         uwsgi_params;
    uwsgi_read_timeout 500;
    uwsgi_send_timeout 500;
    uwsgi_pass      unix:/var/www/testproject_global.sock;
   }

}

这是我的 uwsgi_params：

uwsgi_param  QUERY_STRING       $query_string;
uwsgi_param  REQUEST_METHOD     $request_method;
uwsgi_param  CONTENT_TYPE       $content_type;
uwsgi_param  CONTENT_LENGTH     $content_length;

uwsgi_param  REQUEST_URI        $request_uri;
uwsgi_param  PATH_INFO          $document_uri;
uwsgi_param  DOCUMENT_ROOT      $document_root;
uwsgi_param  SERVER_PROTOCOL    $server_protocol;
uwsgi_param  REQUEST_SCHEME     $scheme;
uwsgi_param  HTTPS              $https if_not_empty;

uwsgi_param  REMOTE_ADDR        $remote_addr;
uwsgi_param  REMOTE_PORT        $remote_port;
uwsgi_param  SERVER_PORT        $server_port;
uwsgi_param  SERVER_NAME        $server_name;

uwsgi_param HTTP_GEOIP_COUNTRY_NAME $geoip_country_name;
uwsgi_param HTTP_X_GEOIP_COUNTRY $geoip_country_code;
uwsgi_param HTTP_GEOIP_COUNTRY_CODE3 $geoip_country_code3;

uwsgi_param HTTP_GEOIP_CITY_COUNTRY_CODE $geoip_city_country_code;
uwsgi_param HTTP_GEOIP_CITY_COUNTRY_CODE3 $geoip_city_country_code3;
uwsgi_param HTTP_GEOIP_CITY_COUNTRY_NAME $geoip_city_country_name;
uwsgi_param HTTP_GEOIP_REGION $geoip_region;
uwsgi_param HTTP_GEOIP_CITY $geoip_city;
uwsgi_param HTTP_GEOIP_POSTAL_CODE $geoip_postal_code;
uwsgi_param HTTP_GEOIP_CITY_CONTINENT_CODE $geoip_city_continent_code;
uwsgi_param HTTP_GEOIP_LATITUDE $geoip_latitude;
uwsgi_param HTTP_GEOIP_LONGITUDE $geoip_longitude;

我已经在 /etc/nginx/geoip/ 中设置了 GeoIP.dat 和 GeoLiteCity.dat

但是当我试图在我的 Django 中获取数据时：

keys_with_values = ''.join("%s=%r <br />" % (key, val) for (key, val) in request.META.iteritems())

它总是返回空值，如下所示：

HTTP_X_GEOIP_COUNTRY='' 
HTTP_GEOIP_COUNTRY_NAME='' 
# etc etc

Answer 1

您的某些 proxy_set_header 标头名称格式错误，但这不是您的问题，因为您实际上没有进行任何代理，没有 proxy_pass 指令。

uwsgi param 指令设置要由uwsgi_pass 传递的标头。您的 Nginx 指令看起来是正确的（尽管最佳做法是让您在自定义标头前加上 X_），但问题是 cgi headers 和 http headers 有不同的协议。

如果你的 Nginx 指令这样说：

uwsgi_param HTTP_X_GEOIP_CITY_COUNTRY_CODE $geoip_city_country_code;

那么您的 HTTP 标头将如下所示：

X-Geoip-City-Country-Code: xyz
