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

ajax

我有一个带有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。

我正在尝试将XHR锁定到特定域。

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:

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.

add_header 'Access-Control-Allow-Origin' "$http_origin";在配置文件中,我只有一个调用,那么为什么会有多个值?有没有办法可以禁用第一个电话,即*

1.)让应用程序动态批准并添加响应头。

$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.)或在启用了Lua的情况下安装Nginx的OpenResty版本,并执行相同的操作,但在Nginx conf文件中使用Lua。
