I want to host my WCF web service on windows service so the front end can access the methods.
The service runs fine if I clicked on the service(view in Browser) in VS. But when I tired to host it using Windows Service, it's returning "Endpoint not found" from the browser when I used the base address and "Method Not Allow" When I specific the method that I want to access.
Below is my code:
Host's App.Config:
<?xml version="1.0" encoding="utf-8" ?>

}
}

I couldn't figure out the issue with Windows Service (the service is hosted successfully tho) so I switched it to IIS(config and CORS also took me some time to resolved), now it's working :)

Hi I'm trying to post a Uint8Array from angular javascript client to wcf service. The problem is that when
the array arrives at the service it is null. On the client end I've tried changing the array to different
types (int8, int16 etc..) and also not stringifying the data, but in all cases when it arrives at the
service it is null. On the service side I've tried to change the BodyStyle of the interface
from Wrapped to Bare, but got a 500 error. I've also made changes to web config parameters,
but I think web config is ok, because the post is actually making it to the method.
Any ideas what could be the problem? ultimately I'm trying to post an image from webcam on ipad or laptop
to wcf service for input into sql server. My code is below
Thanks
Pete
//ANGULAR post to WCF
const data = new Uint8Array(8);
data[0] = 26;
let body:any = JSON.stringify(data);// body = '{"0":26,"1":0,"2":0,"3":0,"4":0,"5":0,"6":0,"7":0}'
let headers = {'Access-Control-Allow-Credentials':'false',
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'DELETE, POST, GET, OPTIONS, PUT',
'Access-Control-Allow-Headers': 'application/json',

this.http.post(GlobalConstants.UploadServiceURL + "UploadPhotoDB", body, {'headers':headers}).subscribe(data => {
console.log(data);// null
})

On the angular javascript side I'm using ngx-webcam module to get the image. This has an imageAsBase64 property which stores the image as a base64 string. When I posted this string to the service and used FromBase64String on the c# wcf service to convert back to a byte array it worked.
Hi I'm posting to a wcf service from javascript. I can post a single parameter (string, blob, int) fine, but when I try to put the data in a class I get a 400 Bad Request error. I've tried both Bare and Wrapped for my BodyStyle, but get the same error for each. Any ideas what could be happening?
Thanks

The problem was in my javascript call. I needed to set the content of the request header to "application/json" and needed to create a String serial of the object before I sent it -- used dojo.toJson from the dojo library:
var TestData = {SubmissionID: "1" };
xhr.setRequestHeader("Content-type", "application/json");
var xhr = new XMLHttpRequest();
xhr.open('POST',
'http://localhost:59070/WCFUploader.svc/Upload/', true);
xhr.send(dojo.toJson(TestData));//this worked!!
I'm trying to save an html5 canvas content, to localhost by using a webserver.
I'm getting the canvas value in base64 and I send it to my webservice.
But when I send the data to the webservice I get this error and the file is not saved:
415: "Cannot process the message because the content type
'application/octet-stream' was not the expected type 'text/xml;
charset=utf-8'."
What am I doing wrong?

The error is the call that you made by Javascript code. You try to send a string, the webservice expected an XML message:
expected type 'text/xml; charset=utf-8'.
I don't know how complicated it is to compose a webservice XML message from Javascript, but I think that you can change your approach. Your service is hosted under IIS, can you build an HttpHandler?
public class UploadBase64 : IHttpHandler
{
public bool IsReusable
{
get { return true; }
}
public void ProcessRequest(HttpContext context)
{
string image_string = string.Empty;
using (StreamReader sr = new StreamReader(context.Request.InputStream))
image_string = sr.ReadToEnd();
byte[] image_bin = Convert.FromBase64String(image_string);
File.WriteAllBytes(#"c:\temp_10\test01.png", image_bin);
}
}
...and add this to your web.config file:
<system.web>
<httpHandlers>
<add verb="POST" path="UploadBase64.aspx" type="WebApplication1.UploadBase64"/>
</httpHandlers>
</system.web>
I have 2 projects from which I need to call WCF services.
I have a problem calling services from one of them.
Therefore I made a simple service which is identical in both projects called Test1.
The SVC, ISVC and the Web.Config files are identical.
Any ideas what else can influance and be the reason why one project is working file and the other return a Bad request error.
I am working with Visual studio 2012.
Following is my code:
SVC file:
namespace Proj1.Web
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Proj1SVC : IProj1SVC
{
public string Test1()
{
return "Project 1";
}
}
}
ISVC file:
namespace Proj1.Web
{
[ServiceContract]
public interface IProj1SVC
{
[OperationContract]
string Test1();
}
}
Web.Config file:

you need to specify attributes at operation level in the service contract file for each method or operation. To do this, decorate the method with WebInvoke, which marks a service operation as one that responds to HTTP requests other than GET. Accordingly, your operational level code in the contract file will be as follows:
[OperationContract]
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.Wrapped,
ResponseFormat = WebMessageFormat.Json)]
string Test1(string Id);
You need to change the default configuration created by Visual Studio in Web.Config file for WCF services, so that it works with the HTTP protocol request send by jQuery client code.

I have written one wcf Service with netHttpBinding binding and hosted in II8(windows server 2012).The interfaces are like the bellow.
[ServiceContract(CallbackContract = typeof(IDuplexCallbackContract))]
public interface IHelloWebSocket
{
[OperationContract(IsOneWay = true, Action = "*")]
void SayHelloDuplexReceive(string name);
}
[ServiceContract]
public interface IDuplexCallbackContract
{
[OperationContract(IsOneWay = true, Action = "*")]
void SayingHelloSend(string message);
}
now I have the service class implementation like the bellow..
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Reentrant)]
public class HelloWebSocket : IHelloWebSocket
{
/// <summary>
/// Call back instance called from service to client.
/// </summary>
IDuplexCallbackContract _callback = null;
public HelloWebSocket()
{
_callback =
OperationContext.Current.GetCallbackChannel<IDuplexCallbackContract>();
}
public void SayHelloDuplexReceive(string name)
{
_callback.SayingHelloSend("Hello " + name + " by WebSockets");
//return "Hello " + name;
}
}
and the web config like the bellow..
<system.serviceModel>
<services>
<service name="WebSocketUndersranding.HelloWebSocket">
<endpoint address=""
binding="netHttpBinding"
contract="WebSocketUndersranding.IHelloWebSocket"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="">
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
multipleSiteBindingsEnabled="true" />
</system.serviceModel>
Now How Can I call the Service from the HTML5 client.??
My Service URL is a link
I am trying to write the client
var websocket = new WebSocket(uri);
but what should I put in the "uri" to call the service.I am not able to get..???
Thanks,
Arijit
