WCF/WF - Consume Wcf Using REST from Android client

Hi,

My question is about WCF service I wrote in C#, and android client which consume it using “REST” protocol.

I am using example from this link:

http://fszlin.blogspot.com/2010/05/comsuming-wcf-services-with-android.html

I am working with visual studio 2010 .net framework 4.

I wrote a simple WCF service and deployed it to IIS on windows 7.

I succeed to access the service from android (10.0.2.2 is localhost when using android emulator):

http://10.0.2.2/WcfAndroid3/VehicleService.svc

It returns HTML test page with “200 OK”.

 

But when I try to access the function “GetPlates” in the service (or any other function) I get “HTTP/1.1 400 Bad Request”:

http://10.0.2.2/WcfAndroid3/VehicleService.svc/GetPlates

This is my function declaration in my interface:

[OperationContract]     

      [WebGet(       

        UriTemplate = "/GetPlates",

        BodyStyle = WebMessageBodyStyle.WrappedRequest,

        ResponseFormat = WebMessageFormat.Json,

        RequestFormat = WebMessageFormat.Json)]

      IList<string> GetPlates();

 

How can I know if my functions are accessible from "outside" users using “REST” protocol?

I tried a lot, adding and removing function attributes but I still get the error.

I will appreciate any help with this.

Thanks in advance!

http://10.0.2.2/WcfAndroid3/VehicleService.svc

The range of IP addresses from

10.0.0.0

to 10.255.255.255

Is a private address range and is not visible from the public internet.

First, thanks for the answer.
Can I do something about this? I think I must use 10.0.2.2 as localhost?
Can I give my Website alias or any other thing I can do?
Thanks again.

The problem is that your Android (or any other phone) is using its own connectivity to go onto the internet. Since the address you are using is a private class IP address, you are plain out of luck.

www.eggheadcafe.com (72.29.94.50)  on the other hand, is a public internet IP address.

Hello,

I uploaded my WCF test service to here:

http://www.aaa.gamedroid.biz/VehicleService.svc

Still, I can access the service but not the functions in it, if I call http://www.aaa.gamedroid.biz/VehicleService.svc I receive a test page with 200 ok.

But if I call this http://www.aaa.gamedroid.biz/VehicleService.svc/f3 (f3 is function name in the wcf) I receive status code 400.

I tried a lot and don’t understand what I do wrong:

This is a part of my wcf code:

Intreface:

[OperationContract]
[WebInvoke(

UriTemplate = "f3")]

string f3();

Class:
public string f3() {
 return "Hello";
}

 

web.config:
<system.serviceModel>
    <behaviors>
    <endpointBehaviors>
      <behavior name="httpBehavior">
      <webHttp />
      </behavior>
    </endpointBehaviors>
    <serviceBehaviors>
      <behavior name="">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
      </behavior>
    </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <services>
    <service name="HttpWcfWeb.VehicleService">
      <endpoint address=""
           behaviorConfiguration="httpBehavior"
           binding="webHttpBinding"
           contract="HttpWcfWeb.IVehicleService" />
    </service>
    </services>
  </system.serviceModel>

 

Is there any problem with my code?
