Qfyilyi

I'm able to login to Thingsboard website using my credentials, however when I try to connect the same using CURL command I get "Authentication Failed" error.

curl -X POST "https://cloud.thingsboard.io/api/auth/login" -d "{"username":"XYZPQR@ABCDLMN.com", "password":"Q@34&pwn"}" --header "Content-Type: application/json" --header "Accept: application/json"

Error Code

{"status":401,"message":"Authentication failed","errorCode":10,"timestamp":1542893993515}

However when I use the same user id and Password in my ASP.NET Application to fetch the authorization token, I do get the JWT token, but using the same token I'm unable to make any REST API call from Thingsboard.

ASP.NET CORE CODE

var response = new HttpResponseMessage();

var client = new HttpClient();                

UserModel model = new UserModel { username = "XYZPQR@ABCDLMN.com", password = "Q@34&pwn" };

var content = new StringContent(JsonConvert.SerializeObject(model), Encoding.UTF8, "application/json");



response = await client.PostAsync("https://cloud.thingsboard.io/api/auth/login", content);



string data = await response.Content.ReadAsStringAsync();



var userToken = JsonConvert.DeserializeObject<UserToken>(data);



MediaTypeWithQualityHeaderValue contentType = new MediaTypeWithQualityHeaderValue("application/json");



client.DefaultRequestHeaders.Accept.Add(contentType);



client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", userToken.token);

Uri url = new Uri("https://cloud.thingsboard.io/api/plugins/telemetry/DEVICE/431be6e0-e8ca-11e8-9e5c-3d544ba4fdfc/values/timeseries?keys=Electricity");



response = await client.GetAsync(url);

Model Class

 public class UserModel {

        public string username { get; set; }

        public string password { get; set; }

    }



    public class UserToken

    {

        public string token { get; set; }

        public string refreshToken { get; set; }

    }

Please suggest, how to get the telemetry values from Thingsboard REST API.

It was a small mistake I was doing; I changed old code to new code(as shown below), and everything started working as expected.

Old code

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", userToken.token);

New Code

client.DefaultRequestHeaders.Add("X-Authorization", "Bearer " + userToken.token);

Thanks for support.
