SSL and ServiceStack

SSL and ServiceStack

Ok now I have my ServiceStack working with Android using the native ServiceStack client (AndroidServiceClient). I have now implemented SSL. I've opted for Self Signed Certs at the moment.

My current setup is:

Desktop->Cisco Router->Android

The desktop requires the Self Signed Certificate creating, I'm using SelfSSL.exe for the job.
C:\ssl>selfssl /N:CN=YourSerivceName /V:9999

Then Add Snap-In Certificate Manager running under Local Machine.
Copy your  YourSerivceName cert to the Trusted Root Certification Authorities

C:\netsh http add sslcert ipport= appid={yyyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyy} certhash=zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

xxxx is the listening SSL port
{yyyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyy}  is the the assembky guid from AssemblyInfo.cs in your ServiceStack application.

zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz is the Thumbprint from your YourSerivceName certificate.

In may case the to allow port xxxx through on my desktop firewall.
On my cisco router I have forward the port:
ip nat inside source static tcp desktop.pc.address xxxx my.wan.addreess xxxx extendable

Then allow the port to be accessible on the inbound rule
access-list aaa permit tcp any host my.wan.address eq xxxx

To test the port is open, start your ServiceStack application
new AppHost().Init().Start("https://+:xxxx/");
then use a free online port checking tool to see if all in ok. I use  

Congratulations you created a ServiceStack SSL service!

AndroidServiceClient with Authentication

I'm currently researching ServiceStack as a replacement to my own services for handling REST between Android and Windows.

I've got the client (Android) working using loopj's AsyncHttpClient. But I was looking for a more native library. Initially I was using Jsonserviceclient but decided on the AndroidServiceClient. The problem I had was setting up basic authentication on the connection. After a few hours of reading (which AndroidServiceClient extends). It transpired I have to implement my own request ConnectionFilter and set uo the request headers in the void exec(HttpURLConnection urlConnection) method.

After creating code I got the error "cannot set request property after connection is made".
Seems I needed to tweak the code to suppress this error.

package com.jjoplc.pod.Views;

import android.util.Base64;
import net.servicestack.client.ConnectionFilter;

 * Created by norm on 01/07/2015.
public class CustomRequestFilter implements ConnectionFilter {

    private String password = "";
    private String username = "";

    static  boolean done = false;
    public void exec(HttpURLConnection urlConnection) {
        if (done) {
            done = false;

        done = true;

        String credentials = username + ":" + password;
        final String basicAuth = "Basic " + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);
        urlConnection.setRequestProperty("Authorization", basicAuth);

    public void setUsername(String userName) {
        this.username = userName;

    public void setPassword(String passWord) {
        this.password = passWord;

Set up.

 _androidClient = new AndroidServiceClient("http://myservice:8088");
_requestFilter = new CustomRequestFilter();
_androidClient.RequestFilter = _requestFilter;

And Test.

androidClient.getAsync(new dto.Hello().setName("Normski"), new AsyncResult<dto.HelloResponse>() {
    public void success(dto.HelloResponse r) {

    public void error(Exception ex) {
