Reading HttpResponseMessage.Content throws Newtonsoft.Json.JsonReaderException when reading webapi 2 token

After some intense googling I got my code working.

First thing I did was added an extra class to store the token.

class TokenResponseModel
{
    [JsonProperty("access_token")]
    public string AccessToken { get; set; }

    [JsonProperty("token_type")]
    public string TokenType { get; set; }

    [JsonProperty("expires_in")]
    public int ExpiresIn { get; set; }

    [JsonProperty("userName")]
    public string Username { get; set; }

    [JsonProperty(".issued")]
    public string IssuedAt { get; set; }

    [JsonProperty(".expires")]
    public string ExpiresAt { get; set; }
}

After that I changed my code to the following code.

static internal async Task<TokenResponseModel> GetBearerToken(string siteUrl, string Username, string Password)
{
    HttpClient client = new HttpClient();
    client.BaseAddress = new Uri(siteUrl);
    client.DefaultRequestHeaders.Accept.Clear();

    HttpContent requestContent = new StringContent("grant_type=password&username=" + Username + "&password=" + Password, Encoding.UTF8, "application/x-www-form-urlencoded");

    HttpResponseMessage responseMessage = await client.PostAsync("Token", requestContent);

    if (responseMessage.IsSuccessStatusCode)
    {
        string jsonMessage;
        using (Stream responseStream = await responseMessage.Content.ReadAsStreamAsync())
        {
            jsonMessage = new StreamReader(responseStream).ReadToEnd();
        }

        TokenResponseModel tokenResponse = (TokenResponseModel)JsonConvert.DeserializeObject(jsonMessage, typeof(TokenResponseModel));

        return tokenResponse;
    }
    else
    {
        return null;
    }
}

I can now get the bearer token from a WebAPI 2 site in my client so I can add it to future request. I hope it is helpful to someone else.

Another way to do it is:

TokenResponseModel tokenResponse = await response.Content.ReadAsAsync<TokenResponseModel>();
