动态endpointWSO2 API管理器未更新TO标头

Question

嗨，我遇到了几个博客和论坛，我仍然无法实现动态endpointurl更新，我的需求是根据请求参数值更新APIendpointurl。因此，我尝试在WSO2 Api Manager 2.6.0中使用动态endpoint特性。我已经上传了在流序列与下面的代码。但我还是明白错误。

在流代码：

<sequence xmlns="http://ws.apache.org/ns/synapse" name="admin--dynamicAPI_v1.0" trace ="enable">
   <property name="REST_URL_POSTFIX" scope="axis2" action="remove"/>
   <log level="full">    
    <property name="headerTo" value="http://actualurl/tobe/redirected"/>
    <header name="To" expression="get-property('headerTo')"/>
    <property name="ENDPOINT_ADDRESS" value="http://actualurl/tobe/redirected"/>
 </log>
</sequence>

这是因为您已经在日志中介器中完成了这一操作。你能像下面这样试试吗。

<sequence xmlns="http://ws.apache.org/ns/synapse" name="admin--dynamicAPI_v1.0" trace ="enable">
   <property name="REST_URL_POSTFIX" scope="axis2" action="remove"/>
   <property name="headerTo" value="http://actualurl/tobe/redirected"/>
   <header name="To" expression="get-property('headerTo')"/>
   <log level="full">    
      <property name="ENDPOINT_ADDRESS" expression="get-property('headerTo')"/>
   </log>
</sequence>
