示例1: SendAsync
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
// Message handler is created on application start, not per request, so we need to resolve the authentication service using the dependencyscope (this is in request scope)
_authenticationService = request.GetDependencyScope().GetService(typeof(IAuthenticationService)) as IAuthenticationService;
if (_authenticationService == null)
{
throw new ApplicationException("Authentication service cannot be resolved");
}
// Try get authentication header
var authorisationHeader = request.Headers.Authorization;
// If authentication header is available and is set to basic authentication
if (authorisationHeader != null && Scheme.Equals(authorisationHeader.Scheme))
{
string username;
string password;
try
{
username = authorisationHeader.Username();
password = authorisationHeader.Password();
}
catch
{
// If authorization header cannot be properly read, give back sensible error
return request.CreateResponse(HttpStatusCode.BadRequest, "Authorization header is not properly formatted.");
}
// Authenticate request
var authenticateResponse = _authenticationService.IsAuthenticated(username, password);
// Set user if authentication is successfull
if (authenticateResponse)
{
var claimsIdentity = new ClaimsIdentity(AuthenticationTypes.Password);
claimsIdentity.AddClaim(new Claim(ClaimTypes.Name, username));
// Do not use thread.principal or httpcontext to set user. This will create dependency on system.web, which stands in the way of self hosting
// http://brockallen.com/2013/10/27/host-authentication-and-web-api-with-owin-and-active-vs-passive-authentication-middleware/
request.GetRequestContext().Principal = new ClaimsPrincipal(claimsIdentity);
}
}
// Process request
var response = await base.SendAsync(request, cancellationToken);
// Add header to indicate basic authentication is needed when request is unauthorized
if (response.StatusCode == HttpStatusCode.Unauthorized)
{
response.Headers.WwwAuthenticate.Add(new AuthenticationHeaderValue(Scheme));
response.Content = new JsonContent(new { Error = "Unauthorized" });
}
