Can';t使GWT应用程序与Tomcat 7上配置的CORS一起工作
我正在尝试将GWT应用程序配置为与不同的后端服务器(运行Tomcat7.0.26)一起工作 我按照本网站的说明配置了CORS过滤器: 我使用了样例GWT代码(问候语应用程序),并进行了以下修改:Can';t使GWT应用程序与Tomcat 7上配置的CORS一起工作,gwt,tomcat7,cors,Gwt,Tomcat7,Cors,我正在尝试将GWT应用程序配置为与不同的后端服务器(运行Tomcat7.0.26)一起工作 我按照本网站的说明配置了CORS过滤器: 我使用了样例GWT代码(问候语应用程序),并进行了以下修改: 在GWT应用程序中,我在RPC调用之前添加了这一行: ((ServiceDefTarget) greetingService).setServiceEntryPoint("http://remoteserver/testcors/greet"); 我修改了web.xml并添加了CORS过滤器: &
((ServiceDefTarget) greetingService).setServiceEntryPoint("http://remoteserver/testcors/greet");

但是,如果访问本地计算机上运行的同一个TestCORS GWT应用程序(127.0.0.1:8888),则会出现以下错误:
请求标头:

我尝试了不同的浏览器(Chrome版本24.0.1312.57、Safari版本6.0.2(8536.26.17)、Firefox 18.0.2、Opera版本12.14),但服务器返回了相同的错误-HTTP 403
我看到很少有人有类似的问题,但我无法找到解决方案:
非常感谢您的帮助 我以前没有使用过这个cors过滤器,我更喜欢像这样最简单的过滤器 无论如何,在您的情况下,您似乎没有正确配置gwt需要工作的标题,您的应用程序正在发送:
Access-Control-Request-Headers: x-gwt-module-base, x-gwt-permutation, origin, content-type
因此,您的配置应具有:
<init-param>
<param-name>cors.supportedHeaders</param-name>
<param-value>x-gwt-module-base, x-gwt-permutation, origin, content-type</param-value>
</init-param>
cors.supportedHeaders
x-gwt-module-base,x-gwt-permutation,来源,内容类型
多亏了弗拉基米尔,我还从这个网站上获得了CORS过滤器:
我在web.xml中添加了其他受支持的标题:
<init-param>
<param-name>cors.supportedHeaders</param-name>
<param-value>Content-Type, X-Requested-With, x-gwt-module-base, x-gwt-permutation, origin, content-type</param-value>
</init-param>
cors.supportedHeaders
内容类型,X-request-With,X-gwt-module-base,X-gwt-permutation,来源,内容类型
实际上,当我尝试以下操作时,它是有效的:[1]:[2]:
<init-param>
<param-name>cors.supportedHeaders</param-name>
<param-value>Content-Type, X-Requested-With, x-gwt-module-base, x-gwt-permutation, origin, content-type</param-value>
</init-param>
