码头跨源过滤器

Jetty Cross Origin Filter(码头跨源过滤器)

问题描述

我已经配置了 Jetty 的跨域过滤器，但我仍然收到以下错误.有谁知道出了什么问题以及如何解决?错误消息下方是我的覆盖描述符(即补充 web.xml)

I've configured Jetty's cross origin filter, but I continue to get the following error. Does anyone know what is wrong and how to fix it? Below the error message is my override descriptor (i.e. supplemental web.xml)

错误:

Origin http://localhost:8090 is not allowed by Access-Control-Allow-Origin.

覆盖描述符:

推荐答案

Aloha,

我也为此奋斗了一段时间，发现最终节点需要是:

I fought this for awhile as well, and found that the final node needs to be:

<filter-mapping>
    <filter-name>cross-origin</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

不是

<filter-mapping>
     <filter-name>cross-origin</filter-name>
     <filter-pattern>/*</filter-pattern>
</filter-mapping>

这是我找到的对我有帮助的链接:wiki.eclipse.org/Jetty/Feature/Cross_Origin_Filter

Here is the link I found to help me: wiki.eclipse.org/Jetty/Feature/Cross_Origin_Filter

在我更新了 web.xml 文件并重新启动了码头服务器后，我能够使用 jQuery ajax 调用进行跨域请求.

After I updated my web.xml file and restarted the jetty server, I was able to make cross domain request using jQuery ajax calls.
