I've been working through a simple API example, a modified version of the ServiceStack Hello World example with authentication. The goal of the proof of concept is to create an a RESTful API that contains services requiring authentication accessible entirely through Ajax from several different web projects.
I've read the wiki for, and implemented, Authentication and authorization and implementing CORS (many, results [sorry, not enough cred to point to the relevant link]). At this point, my Hello service can authenticate using a custom authentication mechanism which is over-riding CredentialsAuthProvider and a custom user session object. I've created, or borrowed, rather, a simple test application (an entirely separate project to simulate our needs) and can authenticate and then call into the Hello service, passing a name, and receive a 'Hello Fred' response through a single browser session. That is, I can call the /auth/credentials path in the url, passing the username and id, and receive a proper response. I can then update the url to /hello/fred and receive a valid response.
My breakdown in understanding is how to implement the authentication for all ajax calls. My initial login, below, works fine. No matter what I do, my attempt to call the authenticated service via ajax, I either receive a OPTIONS 404 error or Not Found error, or Origin http // localhost:12345 (pseudo-link) is not allowed by Access-Control-Allow-Origin, etc.
Do I need to go this route?
Sorry if this is confusing. I can provide greater details if required, but think this might be sufficient help the knowledgeable to help my lack of understanding.
function InvokeLogin() {
var Basic = new Object();
Basic.UserName = "MyUser";
Basic.password = "MyPass";
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: JSON.stringify(Basic),
url: "http://localhost:58795/auth/credentials",
success: function (data, textStatus, jqXHR) {
alert('Authenticated! Now you can run Hello Service.');
},
error: function(xhr, textStatus, errorThrown) {
var data = $.parseJSON(xhr.responseText);
if (data === null)
alert(textStatus + " HttpCode:" + xhr.status);
else
alert("ERROR: " + data.ResponseStatus.Message + (data.ResponseStatus.StackTrace ? " \r\n Stack:" + data.ResponseStatus.StackTrace : ""));
}
});
}
EDIT:
Based on the responses and the link provided by Stefan, I've made a couple of changes:
My Config (Note: I'm using custom authentication and session object and that is all working correctly.)
public override void Configure(Funq.Container container)
{
Plugins.Add(new AuthFeature(() => new CustomUserSession(),
new IAuthProvider[] {
new CustomCredentialsAuthProvider(),
}));
base.SetConfig(new EndpointHostConfig
{
GlobalResponseHeaders = {
{ "Access-Control-Allow-Origin", "*" },
{ "Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS" },
{ "Access-Control-Allow-Headers", "Content-Type, Authorization" },
},
DefaultContentType = "application/json"
});
Plugins.Add(new CorsFeature());
this.RequestFilters.Add((httpReq, httpRes, requestDto) =>
{
//Handles Request and closes Responses after emitting global HTTP Headers
if (httpReq.HttpMethod == "OPTIONS")
httpRes.EndRequest(); // extension method
});
Routes
.Add<Hello>("/Hello", "GET, OPTIONS");
container.Register<ICacheClient>(new MemoryCacheClient());
var userRep = new InMemoryAuthRepository();
container.Register<IUserAuthRepository>(userRep);
}
My Simple Hello Service
[EnableCors]
public class HelloService : IService
{
[Authenticate]
public object GET(Hello request)
{
Looks strange when the name is null so we replace with a generic name.
var name = request.Name ?? "John Doe";
return new HelloResponse { Result = "Hello, " + name };
}
}
After making the login call, above, my subsequent call the Hello service is now yielding a 401 error, which is progress, though not where I need to be. (The Jquery.support.cors= true is set in my script file.)
function helloService() {
$.ajax({
type: "GET",
contentType: "application/json",
dataType: "json",
url: "http://localhost:58795/hello",
success: function (data, textStatus, jqXHR) {
alert(data.Result);
},
error: function (xhr, textStatus, errorThrown) {
var data = $.parseJSON(xhr.responseText);
if (data === null)
alert(textStatus + " HttpCode:" + xhr.status);
else
alert("ERROR: " + data.ResponseStatus.Message +
(data.ResponseStatus.StackTrace ? " \r\n Stack:" + data.ResponseStatus.StackTrace : ""));
}
});
}
Again, this works in the RESTConsole if I first make the call to /auth/credentials properly and then follow that up with a call to /hello.
FINAL EDIT Following Stefan's advise, below, including many other links, I was finally able to get this working. In addition to Stefan's code, I had to make one additional modification:
Plugins.Add(new CorsFeature(allowedHeaders: "Content-Type, Authorization"));
On to the next challenge: Updating Jonas Eriksson's CustomAuthenticateAttibute code (which appears to be using an older version of ServiceStack as a couple of functions are no longer available.
THANKS AGAIN STEFAN!!
