使用ClientId和ClientSecret进行Web API授权

我在网络api授权中使用OWIN / Katana中间件。

流程。

我向请求客户发出acess_tokenrefresh_token

access_token的生命周期很短,而refresh_token的有效期很长。

像往常一样,如果access_token过期,它将使用refresh_token请求另一个access_token。

现在,我的问题。由于我的refresh_token有很长的生命周期,看起来它失败了短命的access_token的目的。让我们说如果refresh_token被泄露,黑客仍然可以获得access_token,对吗?

我查看了谷歌和微软的OAuth实现,看起来除了refresh_token之外,他们还需要提供这个额外的参数。这是 client_id client_secret 。似乎它是在API开发者页面上登录时生成的。

现在,我如何在我的项目中实现它?我正在考虑覆盖令牌创建并将令牌哈希基于ClientIdClientSecret

我正在使用最新的web api的基本OWIN / Katana身份验证,我不打算使用像Thinktecture这样的其他授权服务器。我只想使用ASP.NET Web API 2默认提供的基本的

Startup.OAuth.cs

public partial class Startup
{
   static Startup()
   {
      PublicClientId = "self";
      UserManagerFactory = () => new UserManager<IdentityUser>(new AppUserStore());
      var tokenExpiry = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["ApiTokenExpiry"]);

      OAuthOptions = new OAuthAuthorizationServerOptions
      {
          TokenEndpointPath = new PathString("/Token"),
          Provider = new ApplicationOAuthProvider(PublicClientId, UserManagerFactory),
          AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
          AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(tokenExpiry),
          AllowInsecureHttp = true,
          RefreshTokenProvider = new AuthenticationTokenProvider
          {
               OnCreate = CreateRefreshToken,
               OnReceive = ReceiveRefreshToken,
          }
      };
   }

   private static void CreateRefreshToken(AuthenticationTokenCreateContext context)
   {
       var tokenExpiry = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["ApiTokenExpiry"]);
       var refreshTokenExpiry = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["ApiRefreshTokenExpiry"]);

       var refreshTokenProperties = new AuthenticationProperties(context.Ticket.Properties.Dictionary)
       {
           IssuedUtc = context.Ticket.Properties.IssuedUtc,
           ExpiresUtc = DateTime.UtcNow.AddMinutes(tokenExpiry + refreshTokenExpiry) // add 3 minutes to the access token expiry
       };

       var refreshTokenTicket = new AuthenticationTicket(context.Ticket.Identity, refreshTokenProperties);

       OAuthOptions.RefreshTokenFormat.Protect(refreshTokenTicket);
       context.SetToken(context.SerializeTicket());
   }

   private static void ReceiveRefreshToken(AuthenticationTokenReceiveContext context)
   {
       context.DeserializeTicket(context.Token);
   }
}

ApplicationOAuthProvider.cs

public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider
{
    private readonly string _publicClientId;
    private readonly Func<UserManager<IdentityUser>> _userManagerFactory;

    public ApplicationOAuthProvider(string publicClientId, Func<UserManager<IdentityUser>> userManagerFactory)
    {
        if (publicClientId == null)
        {
            throw new ArgumentNullException("publicClientId");
        }

        if (userManagerFactory == null)
        {
            throw new ArgumentNullException("userManagerFactory");
        }

        _publicClientId = publicClientId;
        _userManagerFactory = userManagerFactory;
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
         using (UserManager<IdentityUser> userManager = _userManagerFactory())
         {
             IdentityUser user = await userManager.FindAsync(context.UserName, context.Password);

             if (user == null)
             {
                 context.SetError("invalid_grant", "The user name or password is incorrect.");
                 return;
             }

             ClaimsIdentity oAuthIdentity = await userManager.CreateIdentityAsync(user,
                    context.Options.AuthenticationType);
             ClaimsIdentity cookiesIdentity = await userManager.CreateIdentityAsync(user,
                    CookieAuthenticationDefaults.AuthenticationType);
             AuthenticationProperties properties = CreateProperties(user.UserName);
             AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);

             context.Validated(ticket);
             context.Request.Context.Authentication.SignIn(cookiesIdentity);
         }
    }
}

摘要 -

  1. 导航至https://console.developers.google.com/
  2. 选择一个项目。如果你没有,请创建一个。
  3. 在API&#39; S和AUTH下的左侧栏中,选择CREDENTIALS
  4. 您应该看到您的clientID和clientSecret。如果您没有看到这些内容,请单击“创建新客户端ID”并完成该操作。然后应显示您的clientID和clientSecret。
  5. 如果您仍不确定,请参阅此链接:https://developers.google.com/accounts/docs/OAuth2Login#getcredentials

    它描述了如何同时获取clientID和clientSecret。
