  hi

  Can you connect your MongoDB in another app/code?

  Do you have any example code of authMechanism=MONGODB-X509?

  Thanks.

  hi

  You can override the UnitOfWorkMongoDbContextProvider's CreateMongoClient method to change the code of creating MongoClient.

  Add YourUnitOfWorkMongoDbContextProvider : UnitOfWorkMongoDbContextProvider

  Then replace it in DI.

  context.Services.TryAddTransient(
      typeof(IMongoDbContextProvider<>),
      typeof(UnitOfWorkMongoDbContextProvider<>)
  );
  

  https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.MongoDB/Volo/Abp/Uow/MongoDB/UnitOfWorkMongoDbContextProvider.cs#L300-L306

  var connectionString = "mongodb+srv://ibl-mongo.dizxt.mongodb.net/tri-app-db?retryWrites=true&w=majority&appName=ibl-mongo&tls=true&authMechanism=MONGODB-X509&authSource=%24external";
  var settings = MongoClientSettings.FromConnectionString(connectionString);
  settings.ServerApi = new ServerApi(ServerApiVersion.V1);
  
  var cert = new X509Certificate2("C:\\projects\\development\\IBL\\Trabsitaly\\TransitalyApp\\src\\TransitalyApp.HttpApi.Host\\atlas-user-cert.pfx", "changeit");
  
  settings.SslSettings = new SslSettings
  {
      ClientCertificates = new List<X509Certificate>() { cert }
  };
  
  var client = new MongoClient(settings);

  the complete solution for future framework improvement:

  `using System; using System.Collections.Generic; using System.IO; using System.Security.Cryptography; using System.Security.Cryptography.X509Certificates; using Microsoft.Extensions.Configuration; using Microsoft.Extensions.Logging; using Microsoft.Extensions.Options; using MongoDB.Driver; using Org.BouncyCastle.Crypto; using Org.BouncyCastle.Crypto.Parameters; using Org.BouncyCastle.OpenSsl; using Org.BouncyCastle.Security; using Volo.Abp.Data; using Volo.Abp.MongoDB; using Volo.Abp.MultiTenancy; using Volo.Abp.Threading; using Volo.Abp.Uow; using Volo.Abp.Uow.MongoDB;

  public class X509CertificateUnitOfWorkMongoDbContextProvider

  public X509CertificateUnitOfWorkMongoDbContextProvider(IUnitOfWorkManager unitOfWorkManager,
      IConnectionStringResolver connectionStringResolver, ICancellationTokenProvider cancellationTokenProvider,
      ICurrentTenant currentTenant, IOptions<AbpMongoDbContextOptions> options,
      IMongoDbContextTypeProvider dbContextTypeProvider, IConfiguration configuration) : base(unitOfWorkManager,
      connectionStringResolver,
      cancellationTokenProvider, currentTenant, options, dbContextTypeProvider)
  {
      _configuration = configuration;
      this.SetX509AuthenticationMechanism();
  }
  
  private void SetX509AuthenticationMechanism()
  {
      var connectionString = _configuration["ConnectionStrings:Default"];
      if (connectionString is not null && connectionString.Contains("authMechanism=MONGODB-X509"))
      {
          useX509Certificate = true;
          this._certPassword = Guid.NewGuid().ToString();
          var certFilePath = _configuration["ConnectionStrings:X509Certificate:CertFile"];
          var keyFilePath = _configuration["ConnectionStrings:X509Certificate:KeyFile"];
          this._certificate = LoadCertificateFromPem(certFilePath, keyFilePath);
      }
  }
  
  protected override MongoClient CreateMongoClient(MongoUrl mongoUrl)
  {
      var mongoClientSettings = MongoClientSettings.FromUrl(mongoUrl);
      if (useX509Certificate)
      {
          try
          {
              mongoClientSettings.ServerApi = new ServerApi(ServerApiVersion.V1);
              mongoClientSettings.SslSettings = new SslSettings
              {
                  ClientCertificates = new List<X509Certificate>() { _certificate },
              };
              Options.MongoClientSettingsConfigurer?.Invoke(mongoClientSettings);
              return new MongoClient(mongoClientSettings);
          }
          catch (Exception e)
          {
              Logger.LogError(e, "Error while creating MongoClient with X509 certificate");
              throw;
          }
      }
  
      return base.CreateMongoClient(mongoUrl);
  }
  
  
  /// <summary>
  /// Load X509 certificate from PEM file
  /// </summary>
  private X509Certificate2 LoadCertificateFromPem(string? pemFilePath, string? keyFilePath)
  {
      if (pemFilePath is null || keyFilePath is null || !File.Exists(pemFilePath) || !File.Exists(keyFilePath))
      {
          throw new FileNotFoundException($"PEM or Key file not found at {pemFilePath} or {keyFilePath}");
      }
  
      var certificate = X509Certificate2.CreateFromPemFile(pemFilePath, keyFilePath);
      return new X509Certificate2(certificate.Export(X509ContentType.Pfx, _certPassword), _certPassword);
  }
  

  }`

  to replace in a correct way the provider use this code:

  private void ConfigureMongoX509CertificateProvider(ServiceConfigurationContext context, IConfiguration configuration) { context.Services.Replace(ServiceDescriptor.Transient( typeof(IMongoDbContextProvider<>), typeof(X509CertificateUnitOfWorkMongoDbContextProvider<>))); }
