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。

也许我错了，但据我所知，Access-Control-Allow-Origin有一个“origin-list”作为参数。

根据定义，origin-list为:

origin            = "origin" ":" 1*WSP [ "null" / origin-list ]
origin-list       = serialized-origin *( 1*WSP serialized-origin )
serialized-origin = scheme "://" host [ ":" port ]
                  ; <scheme>, <host>, <port> productions from RFC3986

由此，我认为不同的起源是被承认的，并且应该被空间分隔开。

对于多个域，在你的。htaccess:

<IfModule mod_headers.c>
    SetEnvIf Origin "http(s)?://(www\.)?(domain1.example|domain2.example)$" AccessControlAllowOrigin=$0$1
    Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
    Header set Access-Control-Allow-Credentials true
</IfModule>

下面是apache的扩展选项，包括一些最新的和计划中的字体定义:

<FilesMatch "\.(ttf|otf|eot|woff|woff2|sfnt|svg)$">
    <IfModule mod_headers.c>
        SetEnvIf Origin "^http(s)?://(.+\.)?(domainname1|domainname2|domainname3)\.(?:com|net|org)$" AccessControlAllowOrigin=$0$1$2
        Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
        Header set Access-Control-Allow-Credentials true
    </IfModule>
</FilesMatch>

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;
    }
}
