Nginx用户允许多个域的CORS。我喜欢@marshall的例子，尽管他的回答只匹配一个域。为了匹配域和子域的列表，这个正则表达式可以很容易地使用字体:

location ~* \.(?:ttf|ttc|otf|eot|woff|woff2)$ {
   if ( $http_origin ~* (https?://(.+\.)?(domain1|domain2|domain3)\.(?:me|co|com)$) ) {
      add_header "Access-Control-Allow-Origin" "$http_origin";
   }
}

这将只回显与给定域列表匹配的“Access-Control-Allow-Origin”标头。

这招对我很管用:

SetEnvIf Origin "^http(s)?://(.+\.)?(domain\.example|domain2\.example)$" origin_is=$0 
Header always set Access-Control-Allow-Origin %{origin_is}e env=origin_is

当放入。htaccess时，它肯定会工作。

下面是一个Java web应用的解决方案，基于yesthatguy的回答。

我使用的是Jersey REST 1.x

配置web.xml以识别Jersey REST和CORSResponseFilter

<!-- Jersey REST config -->
<servlet>
  <servlet-name>JAX-RS Servlet</servlet-name>
  <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
  <init-param>
    <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
    <param-value>true</param-value>
  </init-param>
  <init-param>
    <param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
    <param-value>com.your.package.CORSResponseFilter</param-value>
  </init-param>
  <init-param>
    <param-name>com.sun.jersey.config.property.packages</param-name>
    <param-value>com.your.package</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>JAX-RS Servlet</servlet-name>
  <url-pattern>/ws/*</url-pattern>
</servlet-mapping>

下面是CORSResponseFilter的代码

import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerResponse;
import com.sun.jersey.spi.container.ContainerResponseFilter;


public class CORSResponseFilter implements ContainerResponseFilter{

    @Override
    public ContainerResponse filter(ContainerRequest request,
            ContainerResponse response) {
        
        String[] allowDomain = {"http://localhost:9000","https://my.domain.example"};
        Set<String> allowedOrigins = new HashSet<String>(Arrays.asList (allowDomain));                  
        
        String originHeader = request.getHeaderValue("Origin");
        
        if(allowedOrigins.contains(originHeader)) {
            response.getHttpHeaders().add("Access-Control-Allow-Origin", originHeader);
                        
            response.getHttpHeaders().add("Access-Control-Allow-Headers",
                    "origin, content-type, accept, authorization");
            response.getHttpHeaders().add("Access-Control-Allow-Credentials", "true");
            response.getHttpHeaders().add("Access-Control-Allow-Methods",
                    "GET, POST, PUT, DELETE, OPTIONS, HEAD");
        }
        
        return response;
    }
}

我在PHP中使用的另一个解决方案:

$http_origin = $_SERVER['HTTP_ORIGIN'];

if ($http_origin == "http://www.domain1.com" || $http_origin == "http://www.domain2.com" || $http_origin == "http://www.domain3.com")
{  
    header("Access-Control-Allow-Origin: $http_origin");
}

为了对. net应用程序进行相当简单的复制/粘贴，我写这个代码是从全局变量中启用CORS。asax文件。这段代码遵循当前接受的回答中给出的建议，将请求中给出的任何原点反映到响应中。这有效地实现了'*'而不使用它。

这样做的原因是它支持多种其他CORS功能，包括发送带有'withCredentials'属性设置为'true'的AJAX XMLHttpRequest的能力。

void Application_BeginRequest(object sender, EventArgs e)
{
    if (Request.HttpMethod == "OPTIONS")
    {
        Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
        Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
        Response.AddHeader("Access-Control-Max-Age", "1728000");
        Response.End();
    }
    else
    {
        Response.AddHeader("Access-Control-Allow-Credentials", "true");

        if (Request.Headers["Origin"] != null)
            Response.AddHeader("Access-Control-Allow-Origin" , Request.Headers["Origin"]);
        else
            Response.AddHeader("Access-Control-Allow-Origin" , "*");
    }
}

Django中还有一个答案。要让一个视图允许来自多个域的CORS，以下是我的代码:

def my_view(request):
    if 'HTTP_ORIGIN' in request.META.keys() and request.META['HTTP_ORIGIN'] in ['http://allowed-unsecure-domain.com', 'https://allowed-secure-domain.com', ...]:
        response = my_view_response() # Create your desired response data: JsonResponse, HttpResponse...
        # Then add CORS headers for access from delivery
        response["Access-Control-Allow-Origin"] = request.META['HTTP_ORIGIN']
        response["Access-Control-Allow-Methods"] = "GET" # "GET, POST, PUT, DELETE, OPTIONS, HEAD"
        response["Access-Control-Max-Age"] = "1000"  
        response["Access-Control-Allow-Headers"] = "*"  
        return response
