TRY OUT WEB API SERVICE #959 | Support Center

Hasan created 10 years ago

Hello Team,

I am building an Android App for my application on top of ASP.net ZERO

I am authenticating through

api/Account/Authenticate

Now, in My app i want to Send the Token automatically without sending Any Username and Password (for example, i want to have a TRY APP Feature )

How to build one ?

I have tried it but it is not allowing me to do that because it expects the Token in my request

Could you please let me know ?

Hi,

You must send token for your every request after authentication. This is what token based authentication is. So, I could not understood the question actually. If you want to automatically send for every request in your android app, then I don't know. It's out of our scope. I suppose you can find info on the web.

I will put it like this

I want to create one more method in the controller like

Account/Authenticate

How to achieve ?

Account/Authenticate does not expect Token.

Hi,

Sorry for the late reply.

You just create controllers and actions. If you do not put [Authorize] or [AbpApiAuthorize] attributes to your action/controller, it's already not authenticated and can be called by any client without token. If you put these attributes, then it's authenticated. As you see, there is no such attributes in <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero/blob/master/src/MyCompanyName.AbpZeroTemplate.WebApi/WebApi/Controllers/AccountController.cs">https://github.com/aspnetzero/aspnet-ze ... troller.cs</a>

Hi,

I have tried a simple scenario.

This is my test controller

public class TestController : ZeroSupportControllerBase { public JsonResult GetTestData() { return Json(new { Name = "ismail", Age = 1 }); } }

When i make a post request to this action (http://localhost:6240/Test/GetTestData) from postman chrome extension i get the following result.

{ "success": true, "result": { "name": "ismail", "age": 1 }, "error": null, "unAuthorizedRequest": false }

It should work the same way with android.

Hasan, I don't think they can answer Your question, as there is no question about ASP.NET Zero actually. There are only two ways to access a resource - with or without authorization. If You want You resource to be accessible without authorization - remove AbpAuthorize tag from Your method. If You want authorization, You will need to send something from Your Android app for the system to authorize. The method Authenticate gives You a token, that You will need to send with Your requests later and it's up to Your Android application to make sure this token is send with later requests. Another way would be to send basic authenticate header with Your api requests, but I am not sure if ASP.NET Zero supports that. On the other hand, this way is a really bad way, so You should not use it.

I think you did not understand the question I need another method like Authenticate in any Controller which should accept no input and but it has to be give me a Token

Is it possible in ASP.net ZERO ?

You cannot authorize "nothing". So, there needs to be a user that You can authorize. If You don't want to send user details - no problem with that, just check and authorize the default user. So, You need to have this default user in Your system - just create a tenant "guest" and admin user for this tenant with any password. Then create new method for login without model:

[HttpPost]
        public async Task<AjaxResponse> Authenticate()
        {
            CheckModelState();

            var loginResult = await GetLoginResultAsync(
                "admin",
                "adminpassword",
                "guest"
                );

            var ticket = new AuthenticationTicket(loginResult.Identity, new AuthenticationProperties());

            var currentUtc = new SystemClock().UtcNow;
            ticket.Properties.IssuedUtc = currentUtc;
            ticket.Properties.ExpiresUtc = currentUtc.Add(TimeSpan.FromMinutes(30));

            return new AjaxResponse(OAuthBearerOptions.AccessTokenFormat.Protect(ticket));
        }

The only difference is that You use predefined values for GetLoginResultAsync instead of values from login model.

Hi Hasan,

I also think. we did not understand your problem Why not copy authenticate method or accountcontroller to create a second one, if you want a method exactly like it?

Hi Hasan,

You need to remove "OAuthBearerOptions" static property from TryController and use "WebApi.Controllers.AccountController.OAuthBearerOptions" in your TryController.
