NGINX的"Access-Control-Allow-Origin"标头包含多个值

问题描述

我有一台具有PHP的NGINX服务器(假设主机名为 http://myserver.com ).我有一个PHP脚本，可以从本地主机上的网页通过XHR访问.我将其用作类似于freegeoip.net的GeoIP服务器.

I have an NGINX server with PHP (let's assume a hostname of http://myserver.com). I have a PHP script that I'm accessing via XHR from a web page on my localhost. I'm using it as a GeoIP server similar to freegeoip.net.

我正在尝试将XHR锁定到特定域.

I'm trying to lock down XHR to specific domains.

这是我的配置设置:

location ~ \.php$ {
    try_files $uri =404;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;

    fastcgi_param GEOIP_COUNTRY_CODE $geoip2_data_country_code;
    fastcgi_param GEOIP_COUNTRY_NAME $geoip2_data_country_name;
    fastcgi_param GEOIP_COUNTRY_GEONAME_ID $geoip2_data_country_geoname_id;
    fastcgi_param GEOIP_CITY_NAME $geoip2_data_city_name;
    fastcgi_param GEOIP_CITY_GEONAME_ID $geoip2_data_city_geoname_id;
    fastcgi_param GEOIP_CONTINENT_CODE $geoip2_data_city_continent_code;
    fastcgi_param GEOIP_CONTINENT_GEONAME_ID $geoip2_data_city_continent_geoname_id;
    fastcgi_param GEOIP_LATITUDE $geoip2_data_city_location_latitude;
    fastcgi_param GEOIP_LONGITUDE $geoip2_data_city_location_longitude;
    fastcgi_param GEOIP_TIME_ZONE $geoip2_data_city_location_timezone;
    fastcgi_param GEOIP_ISP $geoip2_data_city_traits_isp;
    fastcgi_param GEOIP_IP_ADDRESS $geoip2_data_city_traits_ip_address;

    set $cors "";

    if ($http_origin ~* 'https?://(www\.domain1\.com|www\.domain2\.com)')
    {
        set $cors "true";
    }

    if ($cors = 'true')
    {
        add_header 'Access-Control-Allow-Origin' "$http_origin";
        add_header 'Access-Control-Allow-Credentials' 'true';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS';
        add_header 'Access-Control-Allow-Headers' 'Accept,Authorization,Cache-Control,Content-Type,Pragma,DNT,If-Modified-Since,Keep-Alive,Origin,User-Agent,X-Mx-ReqToken,X-Requested-With';
    }

    if ($request_method = 'OPTIONS')
    {
        return 204;
    }
}

我遇到的问题是，当我执行XHR请求时，出现以下错误:

The issue I'm having is that when I execute the XHR request, I get the following error:

XMLHttpRequest cannot load http://myserver.com/. The 'Access-Control-Allow-Origin' header contains multiple values '*, http://localhost', but only one is allowed. Origin 'http://localhost' is therefore not allowed access.

我在配置文件中只有一个对add_header 'Access-Control-Allow-Origin' "$http_origin";的调用，那么为什么有多个值?有什么方法可以禁用第一个呼叫，即*?

I have only one call to add_header 'Access-Control-Allow-Origin' "$http_origin"; in the config file, so why do I have the multiple values? Is there a way I can disable the first call i.e. *?

推荐答案

1.)让应用程序动态批准并添加响应标头.

1.) Have the application dynamically approve and add the response header.

$allowed_domains = ['http://allowed.com','http://another_allowed.com'];

function add_cors_header() {
    if (in_array($_SERVER['http_origin'], $allowed_domains)) {
        header('Access-Control-Allow-Origin', $_SERVER['http_origin']);
    }
}

2.)或安装启用了Lua的Nginx的OpenResty版本并执行相同的操作，但是在Nginx conf文件中使用Lua.

2.) Or install the OpenResty version of Nginx with Lua enabled and do the same, but with Lua in the Nginx conf file.
