Tomcat 5.5的跨源资源共享 [英] Cross-origin resource sharing for Tomcat 5.5

问题描述

我是跨源资源共享的新手，我想在Tomcat 5.5服务器中启用它。

I am new to Cross-origin resource sharing and I want to enable it in a Tomcat 5.5 server. Anybody can give me some hint how can this be achieved?

我想为所有请求设置头文件，并允许所有的请求（ Access-Control-Allow-Origin：* ）

I want to set the header universally for all requests, and to allow all origins (Access-Control-Allow-Origin: *)

推荐答案

如果是静态网站，使用Tomcat 7.0.41，您可以通过构建来轻松控制CORS行为在过滤器中。

If it's a static site, then starting with Tomcat 7.0.41, you can easily control CORS behavior via a built-in filter.

很多事情你只需要编辑全局 web.xml CATALINA_HOME / conf 并添加过滤器定义：

Pretty much the only thing you have to do is edit the global web.xml in CATALINA_HOME/conf and add the filter definition:

     <!-- ================== Built In Filter Definitions ===================== -->

      ...

     <filter>
       <filter-name>CorsFilter</filter-name>
       <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
     </filter>
     <filter-mapping>
       <filter-name>CorsFilter</filter-name>
       <url-pattern>/*</url-pattern>
     </filter-mapping>

    <!-- ==================== Built In Filter Mappings ====================== -->

请注意，Firefox不喜欢 Access-Control-Allow-Origin： * 和具有凭证（Cookie）的请求： 响应具有凭据的请求时，服务器必须指定一个域，并且不能使用通配符。

Be aware, though, that Firefox does not like Access-Control-Allow-Origin: * and requests with credentials (cookies): when responding to a credentialed request, server must specify a domain, and cannot use wild carding.
