Hi Sonja

What is full request URL you are trying to use?

Alex

Hi Alex I'm setting the request url previously with

client.BaseAddress = new Uri(ConfigurationManager.AppSettings["myUrl"]);

and it is outside url, our service provider url. The web api is not in Umbraco, not in our domain but totally outside

Hi Sonja

Where in Umbraco do you run this code? Is it a controller or some service? event?

Maybe there is an issue with async, that isn't working properly.

Thanks,

Alex

Hi Alex,

I'm running the code when a certain page is loaded, when I'm triggering GET of an MVC Controller. It is not inside the controller class but in another class. Is Umbraco blocking something and not allowing this kind of code to run? Please advice how do I proceed

Thanks,

Sonja

I think you have to show more of the code in order for anyone to help you.

This is how I'm sending the login request

public static async Task<LoginResponse> LoginMyUser(LoginRequest request)
        {
            var loginResponse = new LoginResponse();
            client.BaseAddress = new Uri(ConfigurationManager.AppSettings["DGUrl"]);
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            HttpResponseMessage response = await client.PostAsJsonAsync("api/user/login", request);
            response.EnsureSuccessStatusCode();
            if (response.IsSuccessStatusCode)
            {
                var dataObject = response.Content.ReadAsAsync<LoginResponse>().Result;
                loginResponse.token = dataObject.token;
                loginResponse.sessionName = dataObject.sessionName;
                loginResponse.sessionId = dataObject.sessionId;

            }

            loginDgResponse.response = response;

            return  loginDgResponse;
        }

This is how I'm sending it

   var loginRequest = new LoginRequest()
                    {
                        username = ConfigurationManager.AppSettings["dusername"],
                        password = ConfigurationManager.AppSettings["dpassword"]
                    };
                    var getResponse = LoginUser.LoginMyUser(loginRequest).Result; 

The code works perfectly in console application so it is not the code, it is some setting because I never received any response.

I also did a simple MVC application and I got same results. I don't think it is Umbraco but something with IIS or IISExpress maybe

Guys, I still have this problem. Even if it might be MVC related, did nobody ever had such problem and what might be a solution?

If you monitor the request and response with Chrome Developer Tools’ Network tab, or similar, what do you see? What kind of response? Or timeout?

in chrome I'm not seeing the api call. I only see the umbraco get page and it is returning me 302

It might have something to do with how your configuring your HttpClient instance, so more information (code) would be helpful. I see you're using PostAsJsonAsync method, maybe you could replace that with your own code, making it synchronous and doing the json serialization yourself. This just to nail down the issue, once you have found the problem you might put the original code back in.

Another thing you could do to see the network traffic is to use Fiddler or a similar tool. My suggestion to use Chrome Dev Tools will not work since the API call is not from the web client, but from your server.

Hi Tor,

I have tried with Fiddler, and I got Tunnel to the service provider, the result is 200, the response is empty, and the request I can't find. From the response I'm finding

HTTP/1.1 200 Connection Established

FiddlerGateway: Direct

StartTime: 16:31:16.324

Connection: close

EndTime: 16:31:16.385

ClientToServerBytes: 130

ServerToClientBytes: 7

Process:iisexpress:1224

Did I send it correctly? Is the problem with the service provider? Is there some testing web api so I can try to send request there to see if it is going dorrectly from my side and it is not the service provider restriction? I asked the guys from the service provider and they said they don't have any restrictions.

Please advice

If you could find your request in Fiddler, and then compare it to the success calls from postman or the console app you mentioned earlier, then that would be helpful.

-Tor

Actually I have compared the both calls and both calls are OK. So this looks like the problem is when I receive the response. both calls have good request and response but my response is not received

So to be clear,

1. You see the json response in Fiddler?

2. You get stuck on the following line in your code?

HttpResponseMessage response = await client.PostAsJsonAsync("api/user/login", request);

1. Not sure if it's relevant, but the these two lines can be improved:

response.EnsureSuccessStatusCode();
if (response.IsSuccessStatusCode)

since the call to response.EnsureSuccessStatusCode() will throw an exception if response.IsSuccessStatusCode is false. In other words, you don't need the if statement.

-Tor

Hi Tor,

1. yes

2. yes

3. Thanks I will fix this

Good to hear you're getting further here! I'm probably a bit outside of my comfort zone now, but maybe there's something in your code after the the await call (i.e. in the call stack) which causes the request to complete or abort before the async call completes (and continues with the lines after the await)?

Are you using await calls to the top of the call stack?

is working on a reply...
