我有一个ASP.NET Web API 2应用程序,它为所有控制器使用Windows身份验证。我现在需要某些控制器使用基本身份验证。
我知道无法同时启用匿名和Windows身份验证,但是是否可以为某些控制器启用Windows身份验证,为其他控制器启用基本身份验证?

所示的过滤器这是我到目前为止所做的:
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false)]
public class BasicAuthenticationFilter : AuthorizationFilterAttribute
{
private bool _active = true;
private const string ValidUsername = @"Test";
private const string ValidPassword = @"T3st";
public BasicAuthenticationFilter()
{
}
public BasicAuthenticationFilter(bool active)
{
_active = active;
}
public override void OnAuthorization(HttpActionContext actionContext)
{
if (_active)
{
var identity = ParseAuthorizationHeader(actionContext);
if (identity == null)
{
Challenge(actionContext);
return;
}
if (!OnAuthorizeUser(identity.Name, identity.Password, actionContext))
{
Challenge(actionContext);
return;
}
var principal = new GenericPrincipal(identity, null);
Thread.CurrentPrincipal = principal;
if (HttpContext.Current != null)
{
HttpContext.Current.User = principal;
}
base.OnAuthorization(actionContext);
}
}
protected virtual bool OnAuthorizeUser(string username, string password, HttpActionContext actionContext)
{
if (string.IsNullOrWhiteSpace(username) || string.IsNullOrWhiteSpace(password) ||
!username.Equals(ValidUsername) || !password.Equals(ValidPassword))
{
return false;
}
return true;
}
protected virtual BasicAuthenticationIdentity ParseAuthorizationHeader(HttpActionContext actionContext)
{
string authHeader = null;
var auth = actionContext.Request.Headers.Authorization;
if (auth != null && auth.Scheme == "Basic")
{
authHeader = auth.Parameter;
}
if (string.IsNullOrEmpty(authHeader)) return null;
authHeader = Encoding.Default.GetString(Convert.FromBase64String(authHeader));
var tokens = authHeader.Split(':');
if (tokens.Length < 2) return null;
return new BasicAuthenticationIdentity(tokens[0], tokens[1]);
}
private void Challenge(HttpActionContext actionContext)
{
var host = actionContext.Request.RequestUri.DnsSafeHost;
actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized);
actionContext.Response.Headers.Add("WWW-Authenticate", string.Format("Basic realm=\"{0}\"", host));
}
}
BasicAuthenticationIdentity类:
public class BasicAuthenticationIdentity : GenericIdentity
{
public BasicAuthenticationIdentity(string name, string password)
: base(name, "Basic")
{
Password = password;
}
public string Password { get; set; }
}
另外,使用基本身份验证过滤器装饰我的控制器:
[BasicAuthenticationFilter]
[RoutePrefix("api/BasicAuth")]
public class BasicAuthController : ApiController
{
//[BasicAuthenticationFilter]
[HttpGet]
public IHttpActionResult TestBasicAuth()
{
return Ok("success");
}
}
当我从Fiddler打电话给api / BasicAuth时,我回到了401,但它只会带来以下挑战:
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM
此时Fiddler再次尝试,但这次不是通过基本授权方案,而是通过Negotiate。这个也失败了。
然后,当Fiddler最后第三次尝试时,我的过滤器实际上得到了请求,但由于授权方案是Negotiate而不是Basic,我的过滤器也返回Unauthorized。
有没有办法强制控制器只使用BasicAuthenticationFilter?

答案 0 :(得分:0)
您可以 - 因为BASIC AUTH
凭据是在HTTP Headers
中发送的(仅限base64编码)。你不 to&#34;启用&#34;应用程序级别的任何内容,并处理对API端点的HTTP请求&#34;手动&#34; (通过检查标题)。
e.g。基本身份验证标头:Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ=
