如何在ASP.NET Core中集成防火墙身份验证

Question

我有一个现有的ASP.NET Core应用程序，在这里我需要添加防火墙身份验证。是否可以将防火墙web用户界面集成到我的ASP.NET Core应用程序中？

Answer 1

为了在ASP.NET Core应用程序中实现Firebase集成，您应该尝试两个教程。

这是Arno Waegemans的第一教程和Heather的第二。

Answer 2

JWT验证需要手动完成：来源

下面的代码正在验证FirebaseToken (JWT)：

    //Download certificates from google
    HttpClient client = new HttpClient();
    var jsonResult = client.GetStringAsync("https://www.googleapis.com/robot/v1/metadata/x509/securetoken@system.gserviceaccount.com").Result;

    //Convert JSON Result
    var x509Metadata = JObject.Parse(jsonResult)
                        .Children()
                        .Cast<JProperty>()
                        .Select(i => new x509Metadata(i.Path, i.Value.ToString()));

    //Extract IssuerSigningKeys
    var issuerSigningKeys = x509Metadata.Select(s => s.X509SecurityKey);

    //Setup JwtTokenHandler 
    var handler = new JwtSecurityTokenHandler();
    SecurityToken token;
    handler.ValidateToken(user.FirebaseToken, new TokenValidationParameters
    {
        IssuerSigningKeys = issuerSigningKeys,
        ValidAudience = "myApp",
        ValidIssuer = "https://securetoken.google.com/myApp",
        IssuerSigningKeyResolver = (arbitrarily, declaring, these, parameters) => issuerSigningKeys
    }, out token);

public class x509Metadata
{
    public string KID { get; set; }
    public string Certificate { get; set; }
    public X509SecurityKey X509SecurityKey { get; set; }

    public x509Metadata(string kid, string certificate)
    {
        KID = kid;
        Certificate = certificate;
        X509SecurityKey = BuildSecurityKey(Certificate);
    }

    private X509SecurityKey BuildSecurityKey(string certificate)
    {
        //Remove : -----BEGIN CERTIFICATE----- & -----END CERTIFICATE-----
        var lines = certificate.Split('\n');
        var selectedLines = lines.Skip(1).Take(lines.Length - 3);
        var key = string.Join(Environment.NewLine, selectedLines);

        return new X509SecurityKey(new X509Certificate2(Convert.FromBase64String(key)));
    }
}
