我在尝试从具有 JWT 令牌的 API 发出 GET 请求时收到错误 401（未经授权）

Question

Here is my GETRequest method...

 HttpClient client = new HttpClient();
            var dashboardEndpoint = Helper.GetUsersurl;
            client.DefaultRequestHeaders.Clear();
            client.DefaultRequestHeaders.Add("Authorization", "Bearer"+Helper.userprofile.token);

            var result = await client.GetStringAsync(dashboardEndpoint);
            var UsersList = JsonConvert.DeserializeObject<AddedUsers>(result);
            //Users = new ObservableCollection<AddedUsers>(UsersList);

            Emplist.ItemsSource = UsersList.data;

        }

I've tried different method but the token isn't being sent alongside my request and therefore the API is throwing an error 401 at me. Any help will be gladly appreciated please...

Answer 1

So, i later studied the pattern and also the response on postman then i realize I'm supposed to pass only the key and the value. In this context,

HttpClient client = new HttpClient();
            var dashboardEndpoint = Helper.GetUsersurl;
            client.DefaultRequestHeaders.Clear();
            client.DefaultRequestHeaders.Add("Authorization", Helper.userprofile.token);

            var result = await client.GetStringAsync(dashboardEndpoint);
            var UsersList = JsonConvert.DeserializeObject<AddedUsers>(result);
            //Users = new ObservableCollection<AddedUsers>(UsersList);

            Emplist.ItemsSource = UsersList.data;

I only needed to pass Authorization as the key and token as the value. thanks everyone

As @jason said, try to add a space between Bearer and the Token

client.DefaultRequestHeaders.Add("Authorization", "Bearer " + Helper.userprofile.token);
