使用多个 ServiceStack 的身份验证提供程序会引发错误

Question

我打算使用 2 个 ServiceStack 的身份验证提供程序：一个基于 CredentialsAuthProvider 的自定义提供程序称为 remotecreds 和内置的 JwtAuthProvider。我的 AppHost 注册码如下所示

appHost.Plugins.Add(new AuthFeature(() => new UserSession(),
                new IAuthProvider[]
                {
                    new JwtAuthProvider(AppSettings)
                    {
                        RequireSecureConnection = false,
                        HashAlgorithm = "RS256",
                        PublicKeyXml = publicKeyXml,
                        Audiences = new List<string> { $"{AppSettings.GetDictionary("Auth")["Url"]}/resources" },
                        PopulateSessionFilter = PopulateSessionFilter
                    },
                    new RemoteCredentialsAuthProvider(AppSettings)
                    {
                        PopulateSessionFilter = PopulateSessionFilter                  
                    },

                }));

当我使用自定义身份验证提供程序 (POST /auth/remotecreds) 进行身份验证时，尽管身份验证提供程序的代码已正确执行，但 ServiceStack returns 出现以下错误

{
    "responseStatus": {
        "errorCode": "NotSupportedException",
        "message": "PrivateKey required to use: RS256",
        "stackTrace": "[Authenticate: 25/04/2019 9:59:25 AM]:\n[REQUEST: {provider:remotecreds,userName:admin,password:Pa$$word123}]\nSystem.NotSupportedException: PrivateKey required to use: RS256\r\n   at ServiceStack.Auth.JwtAuthProvider.GetHashAlgorithm(IRequest req) in C:\BuildAgent\work\3481147c480f4a2f\src\ServiceStack\Auth\JwtAuthProvider.cs:line 87\r\n   at ServiceStack.Auth.JwtAuthProvider.CreateJwtBearerToken(IRequest req, IAuthSession session, IEnumerable`1 roles, IEnumerable`1 perms) in C:\BuildAgent\work\3481147c480f4a2f\src\ServiceStack\Auth\JwtAuthProvider.cs:line 118\r\n   at ServiceStack.Auth.JwtAuthProvider.Execute(AuthFilterContext authContext) in C:\BuildAgent\work\3481147c480f4a2f\src\ServiceStack\Auth\JwtAuthProvider.cs:line 57\r\n   at ServiceStack.Auth.AuthenticateService.Post(Authenticate request) in C:\BuildAgent\work\3481147c480f4a2f\src\ServiceStack\Auth\AuthenticateService.cs:line 253\r\n   at ServiceStack.Host.ServiceRunner`1.ExecuteAsync(IRequest req, Object instance, TRequest requestDto) in C:\BuildAgent\work\3481147c480f4a2f\src\ServiceStack\Host\ServiceRunner.cs:line 133",
        "errors": []
    }
}

如果我注释掉 AppHost 中的 JwtAuthProvider 注册，上面的相同调用会成功。

所以在这里我很困惑为什么 ServiceStack 调用 JwtAuthProvider 而我清楚地针对我的自定义身份验证提供程序进行了身份验证。

Answer 1

问题是您的 JwtAuthProvider 配置错误，如果您想使用 RSA* 哈希算法，则需要 configured with the private key:

new JwtAuthProvider(AppSettings) { 
    HashAlgorithm = "RS256",
    PrivateKeyXml = AppSettings.GetString("PrivateKeyXml") 
}

它仍然会尝试使用您的自定义 AuthProvider 进行身份验证，但如果您注册了 JwtAuthProvider，它将尝试使用 JWT token in BearerToken 填充 AuthenticateResponse，因此当用户针对您的 Auth Provider 进行身份验证，例如：

var clientnew JsonServiceClient(baseUrl);

var authResponse = client.Post(new Authenticate {
    provider = "remotecreds",
    UserName = username,
    Password = password,
    RememberMe = true,
});

他们将有权访问填充在以下位置的 JWT 令牌：

var jwt = authResponse.BearerToken;

因此，如果配置正确，它将 return 在 BearerToken 中填充 JWT 令牌或如果您删除 JwtAuthProvider 它不会尝试填充它。
