我有我的C＃的Web API以下要求2服务：的Web API 2个自定义身份验证的OAuth承载令牌
该服务通过电子邮件的组合，并且被发送到他们的收件箱的临时密码验证用户，一个身份验证的因素。 我需要在这个身份验证机制中生成OAuth承载标记以保护服务，并使用标准的ASP.NET授权机制通过某种[Authorize]属性检查每个请求对应的令牌。
我已经成功地实现了这些步骤
但我不知道如何开始实施剩余ING步骤
引用的过程仅描述了如何使用ASP.NET Identity个人用户帐户作为身份验证手段，而不是我想要如何进行身份验证。

我确实需要通过检查电子邮件和密码进行身份验证。
有关如何在asp.net Web API中设置身份验证的详细说明，请参阅此post。这应该给你一个关于如何在Web API中实现对你的需求的认证的好主意。如果您有任何疑问或问题，请告诉我。
谢谢， Soma。
我在类似的情况下工作，并实施了验证过滤器（IAuthenticationFilter）和从OAuthAuthorizationServerProvider继承的自定义类。就我而言，我需要使用OAuth和传统令牌对请求进行身份验证。我相信在你的情况下，你需要定制AuthenticationFilter。请参阅下面的AuthenticationFilter的例子：
public class MyAuthenticationFilter : IAuthenticationFilter
{
private readonly string _authenticationType;
/// <summary>Initializes a new instance of the <see cref="HostAuthenticationFilter"/> class.</summary>
/// <param name="authenticationType">The authentication type of the OWIN middleware to use.</param>
public MyAuthenticationFilter(string authenticationType)
{
if (authenticationType == null)
{
throw new ArgumentNullException("authenticationType");
}
_authenticationType = authenticationType;
}
/// <summary>Gets the authentication type of the OWIN middleware to use.</summary>
public string AuthenticationType
{
get { return _authenticationType; }
}
/// <inheritdoc />
public async Task AuthenticateAsync(HttpAuthenticationContext context, CancellationToken cancellationToken)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
HttpRequestMessage request = context.Request;
if (request == null)
{
throw new InvalidOperationException("Request mut not be null");
}
//In my case, i need try autenticate the request with BEARER token (Oauth)
IAuthenticationManager authenticationManager = GetAuthenticationManagerOrThrow(request);
cancellationToken.ThrowIfCancellationRequested();
AuthenticateResult result = await authenticationManager.AuthenticateAsync(_authenticationType);
ClaimsIdentity identity = null;
if (result != null)
{
identity = result.Identity;
if (identity != null)
{
context.Principal = new ClaimsPrincipal(identity);
}
}
else
{
//If havent success with oauth authentication, I need locate the legacy token
//If dont exists the legacy token, set error (will generate http 401)
if (!request.Headers.Contains("legacy-token-header"))
context.ErrorResult = new AuthenticationFailureResult(Resources.SAUTH_ERROR_LEGACYTOKENNOTFOUND, request);
else
{
try
{
var queryString = request.GetQueryNameValuePairs();
if (!queryString.Any(x => x.Key == "l"))
context.ErrorResult = new AuthenticationFailureResult(Resources.SAUTH_ERROR_USERTYPENOTFOUND, request);
else
{
var userType = queryString.First(x => x.Key == "l").Value;
String token = HttpUtility.UrlDecode(request.Headers.GetValues("tk").First());
identity = TokenLegacy.ValidateToken(token, userType);
identity.AddClaims(userType, (OwinRequest) ((OwinContext)context.Request.Properties["MS_OwinContext"]).Request);
if (identity != null)
{
context.Principal = new ClaimsPrincipal(identity);
}
}
}
catch (Exception e)
{
context.ErrorResult = new AuthenticationFailureResult(e.Message, request);
}
}
}
}
/// <inheritdoc />
public Task ChallengeAsync(HttpAuthenticationChallengeContext context, CancellationToken cancellationToken)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
HttpRequestMessage request = context.Request;
if (request == null)
{
throw new InvalidOperationException("Request mut not be null");
}
IAuthenticationManager authenticationManager = GetAuthenticationManagerOrThrow(request);
// Control the challenges that OWIN middleware adds later.
authenticationManager.AuthenticationResponseChallenge = AddChallengeAuthenticationType(
authenticationManager.AuthenticationResponseChallenge, _authenticationType);
return TaskHelpers.Completed();
}
/// <inheritdoc />
public bool AllowMultiple
{
get { return true; }
}
private static AuthenticationResponseChallenge AddChallengeAuthenticationType(
AuthenticationResponseChallenge challenge, string authenticationType)
{
Contract.Assert(authenticationType != null);
List<string> authenticationTypes = new List<string>();
AuthenticationProperties properties;
if (challenge != null)
{
string[] currentAuthenticationTypes = challenge.AuthenticationTypes;
if (currentAuthenticationTypes != null)
{
authenticationTypes.AddRange(currentAuthenticationTypes);
}
properties = challenge.Properties;
}
else
{
properties = new AuthenticationProperties();
}
authenticationTypes.Add(authenticationType);
return new AuthenticationResponseChallenge(authenticationTypes.ToArray(), properties);
}
private static IAuthenticationManager GetAuthenticationManagerOrThrow(HttpRequestMessage request)
{
Contract.Assert(request != null);
var owinCtx = request.GetOwinContext();
IAuthenticationManager authenticationManager = owinCtx != null ? owinCtx.Authentication : null;
if (authenticationManager == null)
{
throw new InvalidOperationException("IAuthenticationManagerNotAvailable");
}
return authenticationManager;
}
}
在WebApiConfig.cs，你需要添加认证过滤器是这样的：
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
// Configure Web API to use only bearer token authentication.
config.SuppressDefaultHostAuthentication();
config.Filters.Add(new MyAuthenticationFilter(OAuthDefaults.AuthenticationType));
}
}
