在我的 Web 应用程序中,我需要调用不同的 Web 服务(由我开发/管理)以通过其余 API 启动/管理资源。Web 服务在tomcat6 上运行。我可以从浏览器日志中看到 POST 请求正在通过,但 GET 请求被禁止。如果我从 Web 服务本身进行相同的调用,那么我看不到任何问题。我已经为 tomcat6 定义了跨源过滤器,并在支持的方法中也提到了 GET,但问题仍然存在。
我已经在应用程序服务器级别本身的 web.xml 中以这种方式定义了跨源过滤器。我正在使用来自http://software.dzhuvinov.com/cors-filter.html的 CORS 过滤器库。这是一个 tomcat6 服务器,过滤器已在 ($TOMCAT6_HOME/conf/web.xml) 中定义如下
<filter>
<filter-name>CORS</filter-name>
<filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
<init-param>
<param-name>cors.allowOrigin</param-name>
<param-value>*</param-value>
</init-param>
<init-param>
<param-name>cors.supportedMethods</param-name>
<param-value>GET, POST, HEAD, PUT, DELETE, OPTIONS</param-value>
</init-param>
<init-param>
<param-name>cors.supportedHeaders</param-name>
<param-value>*</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CORS</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
奇怪的是,webservice 正在接受 POST 调用,但对于 GET 调用,它会抛出 403 - Forbidden 错误,告诉“已禁止访问指定的资源”。
GET 调用的标头如下

Tomcat 访问日志还显示 GET 请求已被禁止,但在任何日志中都没有提供任何线索
- - - [21/Jul/2013:17:17:37 +0000] POST /remote/tunnel?connect HTTP/1.1 200 -

这是我的 servlet 代码。我正在尝试集成鳄梨酱(HTML5 VNC 客户端作为网络服务)
