IP address filtering in fuse proxy web service

joby.kj May 21, 2014 5:26 AM

Hi All,

We are using redhat fuse for creating a proxy for our actual web service .We need to get remote client IP address in fuse . For this we have add a processor in camel route , We are trying to extract HttpServletRequest object from Exchange object , but getting HttpServletRequest as null . We are using fuse ide 6.0.0 .

1) Camel route

</route>

</camelContext>

2) SimpleProcessor.java

public class SimpleProcessor implements Processor {

@Override

public void process(Exchange exchange) {

HttpServletRequest req = exchange.getIn().getBody(HttpServletRequest.class);

if (req != null) {

String remoteAddr = req.getRemoteAddr();

int remotePort = req.getRemotePort();

System.out.println("Client called from " + remoteAddr + ":" + remotePort);

} else {

System.out.println("Could not extract client address!");

}

Thank You

Hi,

Please take a look at the faq here[1], this should help.

Hi Freeman,
Thanks a lot . It is working now.

Now coming to our actual requirement , we need to allow access to the camel web service only for specific IP address range set. Request from other IP address should reject .

For achieving this we can extract the IP address from the request header and compare . Is there any other configuration in camel route for mentioning the allowed/dis allowed IP addresses ?

Thank You

Hi,

I can propose a pure CXF way, that said you can add a cxf in interceptor where you maintain a allowed IP table and extract the remote IP and compare.

Hi Freeman,
                         I have one more doubt . From the above camel route , I need to execute the to uri endpoint based on some conditions in "process" method in SimpleProcessor class.

Eg :
---------------------------------------------------
public void process(Exchange exchange) {

         String IP=127.0.0.1;
         int flag =0;
          Message cxfMessage = exchange.getIn().getHeader(CxfConstants.CAMEL_CXF_MESSAGE, org.apache.cxf.message.Message.class);
         ServletRequest request = (ServletRequest) cxfMessage.get("HTTP.REQUEST");
         String remoteAddress = request.getRemoteAddr();

        if(remoteAddress,equals(IP)){
         flag=1;
      }

     }
---------------------

if flag==0 , then we needn't to execute the second end point (<to uri="cxf:http://localhost:8080/services/myService?serviceClass=com.test.MyService"/> ).

Thank You
