RestSharp HttpBasicAuthentication - example

Question

I have a WPF client using RestSharp and WEB API Service. I try to use HttpBasicAuthenticator as follows:

RestRequest login = new RestRequest(\"/         


        

Answer 1

The following worked for me:

private string GetBearerToken()
{
    var client = new RestClient("http://localhost");
    client.Authenticator = new HttpBasicAuthenticator("admin", "22");
    var request = new RestRequest("api/users/login", Method.POST);
    request.AddHeader("content-type", "application/json");
    request.AddParameter("application/json", "{ \"grant_type\":\"client_credentials\" }", ParameterType.RequestBody);
    var responseJson = _client.Execute(request).Content;
    var token = JsonConvert.DeserializeObject<Dictionary<string, object>>(responseJson)["access_token"].ToString();
    if(token.Length == 0)
    {
        throw new AuthenticationException("API authentication failed.");
    }
    return token;
}

Answer 2

new SimpleAuthenticator("username", username, "password", password) did NOT work with me.

The following however worked:

var client = new RestClient("http://example.com");
client.Authenticator = new HttpBasicAuthenticator(userName, password);

var request = new RestRequest("resource", Method.GET);
client.Execute(request);

Answer 3

RestClient restClient = new RestClient(baseUrl);
restClient.Authenticator = new RestSharp.Authenticators.HttpBasicAuthenticator("admin","22");

RestRequest login = new RestRequest("/api/users/login", Method.POST);
IRestResponse response = restClient.Execute(login);

Alternative answer your first question about retrieval of Auth Header values (Server Side) from How can I retrieve Basic Authentication credentials from the header?:

private UserLogin GetUserLoginCredentials()
{
    HttpContext httpContext = HttpContext.Current;
    UserLogin userLogin;
    string authHeader = httpContext.Request.Headers["Authorization"];

    if (authHeader != null && authHeader.StartsWith("Basic"))
    {
        string encodedUsernamePassword = authHeader.Substring("Basic ".Length).Trim();
        Encoding encoding = Encoding.GetEncoding("iso-8859-1");
        string usernamePassword = encoding.GetString(Convert.FromBase64String(encodedUsernamePassword));
        int seperatorIndex = usernamePassword.IndexOf(':');

        userLogin = new UserLogin()
        {
            Username = usernamePassword.Substring(0, seperatorIndex),
            Password = usernamePassword.Substring(seperatorIndex + 1)
        };
    }
    else
    {
        //Handle what happens if that isn't the case
        throw new Exception("The authorization header is either empty or isn't Basic.");
    }
    return userLogin;
}

Usage of this method might be:

UserLogin userLogin = GetUserLoginCredentials();

Alternative answer on second question about returning the token (Server Side):

var httpResponseMessage = Request.CreateResponse();

TokenResponse tokenResponse;
bool wasAbleToGetAccesToken = _identityServerHelper.TryGetAccessToken(userLogin.Username, userLogin.Password,
            platform, out tokenResponse);

httpResponseMessage.StatusCode = wasAbleToGetAccesToken ? HttpStatusCode.OK : HttpStatusCode.Unauthorized;
httpResponseMessage.Content = new StringContent(JsonConvert.SerializeObject(tokenResponse),
            System.Text.Encoding.UTF8, "application/json");

return httpResponseMessage;

Answer 5

From RestSharp documentation:

var client = new RestClient("http://example.com");
client.Authenticator = new SimpleAuthenticator("username", "foo", "password", "bar");

var request = new RestRequest("resource", Method.GET);
client.Execute(request);

The URL generated for this request would be http://example.com/resource?username=foo&password=bar

So you get the password just as any other parameter (although, it's recommended to use POST method then GET, for security reasons).
