OAuth2 WebApi令牌过期

Question

我试图动态设置令牌到期时间,但它似乎只是默认为20分钟.

这是我的ConfigureAuth:

public void ConfigureAuth(IAppBuilder app)
{

        OAuthOptions = new OAuthAuthorizationServerOptions
        {
            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider(""),
            // In production mode set AllowInsecureHttp = false
            AllowInsecureHttp = true
        };

        // Enable the application to use bearer tokens to authenticate users
        app.UseOAuthBearerTokens(OAuthOptions);

}

这是我的GrantResourceOwnerCredentials方法:

    public override Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {

        context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });

        var hasValidLogin = (new login().authenticate(context.UserName, context.Password, "") == "valid");

        if (hasValidLogin == false)
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
            return Task.FromResult<object>(null);
        }

        var oAuthIdentity = CreateIdentity(context);
        var oAuthProperties = CreateProperties(context);

        AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, oAuthProperties);

        context.Validated(ticket);
        return Task.FromResult<object>(null);
    }

这是我的SetProperties方法,我可以设置过期:

    public static AuthenticationProperties CreateProperties(OAuthGrantResourceOwnerCredentialsContext context)
    {

        IDictionary<string, string> data = new Dictionary<string, string>
        {
            { "client_id", context.ClientId }
        };

        var response = new AuthenticationProperties(data);
        response.ExpiresUtc = DateTime.Now.AddMonths(1);

        return response;
    }

即使在那之后,令牌也会返回:

{
  "access_token": ".....",
  "token_type": "bearer",
  "expires_in": 1199,
  "client_id": ".....",
  ".expires": "Fri, 13 Nov 2015 20:24:06 GMT",
  ".issued": "Fri, 13 Nov 2015 20:04:06 GMT"
}

任何想法为什么我不能设置我目前的到期时间？此服务器将采用具有不同指定到期时间的各种不同客户端,因此我认为这是执行此操作的地方.还有其他地方我应该这样做吗？谢谢!

我们有类似的情况,不同的客户端具有不同的令牌超时,因此我们希望能够相应地设置到期时间.在我们实现的AuthenticationTokenProvider中,我们设置了到期时间,但是在令牌被签名时它被覆盖了.

我们最终满意的解决方案是重写TokenEndpoint方法.然后,我们可以实现客户特定的到期:

    public override Task TokenEndpoint(OAuthTokenEndpointContext context)
    {
        if (context.TokenIssued)
        {
            // client information
            var accessExpiration = DateTimeOffset.Now.AddSeconds(accessTokenTimeoutSeconds);
            context.Properties.ExpiresUtc = accessExpiration;
        }

        return Task.FromResult<object>(null);
    }

您看到的行为直接是由于OAuth2授权服务器在通知中设置它时总是丢弃您自己的到期GrantResourceOwnerCredentials(其他Grant*通知也受到影响):https://github.com/jchannon/katanaproject/blob /master/src/Microsoft.Owin.Security.OAuth/OAuthAuthorizationServerHandler.cs#L386

解决方法是设置AuthenticationTokenProvider.CreateAsync(您使用的类OAuthAuthorizationServerOptions.AccessTokenProvider)的到期日期 :

只需设置context.Ticket.Properties.ExpiresUtc您选择的到期日期,它应该按照预期的方式工作:

public class AccessTokenProvider : AuthenticationTokenProvider
{
    public override void Create(AuthenticationTokenCreateContext context)
    {
        context.Ticket.Properties.ExpiresUtc = // set the appropriate expiration date.

        context.SetToken(context.SerializeTicket());
    }
}

您还可以查看AspNet.Security.OpenIdConnect.ServerOWIN/Katana提供的OAuth2授权服务器的分支,它本身支持设置过期日期GrantResourceOwnerCredentials:https://github.com/aspnet-contrib/AspNet.Security.OpenIdConnect.Server/tree的/ dev
