Question

我有一个使用AD sal开发的插件该插件暴露了许多其他API 这些api是从部署在另一个域上的Web应用程序访问的因此，我的访问权限是跨域的目前我正在使用jsonp进行此类访问我想要做的是在我的opendaylight氢气上启用CORS支持从我设法发现。我需要将我的apis添加到cors-config.xml 但那没用我也尝试在插件web xml中定义过滤器，但是再次没有成功，是否有人为了让这个工作变得有效？

经过长时间的搜索，找到了答案。如果你想在氢释放上启用cors支持：在ODL Web容器（Tomcat）上启用CORS： 1.将以下jar复制到ODL中的插件目录 org.opendaylight.controller.filter阀-1.4.2-SNAPSHOT.jar donload链接： https://nexus.opendaylight.org/service/local/repositories/opendaylight.snapshot/content/org/opendaylight/controller/filter-valve/1.4.2-SNAPSHOT/filter-valve-1.4.2-20141001.225558-591.jar

转到./configuration/tomcat-server.xml

在文件中添加以下标记的行：

<Engine name="Catalina" defaultHost="localhost">
    <Host name="localhost" appBase="" unpackWARs="false" autoDeploy="false" deployOnStartup="false" createDirs="false">
    <Realm className="org.opendaylight.controller.security.ControllerCustomRealm" />
    <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                    prefix="web_access_log_" suffix=".txt" resolveHosts="false"
                    rotatable="true" fileDateFormat="yyyy-MM"
                    pattern="%{yyyy-MM-dd HH:mm:ss.SSS z}t - [%a] - %r"/>

    <!--add this line!-->
    <Valve className="org.opendaylight.controller.filtervalve.cors.FilterValve" configurationFile="configuration/cors-config.xml"/>

  </Host>
</Engine>

在ODL下的配置目录中创建cors-config.xml文件。该文件包含tomcat的过滤器定义。在这里，您可以像定义restconf api一样定义路径并添加CORS过滤器。

<Host>

    </init-param>
  </filter-template>

  <Context path="/restconf">
    <filter>
      <filter-name>CorsFilter</filter-name>
      <!-- init params can be added/overriden if template is used> -->
    </filter>
    <!-- references to templates without <filter> declaration are not allowed -->
    <filter-mapping>
      <filter-name>CorsFilter</filter-name>
      <url-pattern>/*</url-pattern>
