A MongoDb UserStore and RoleStore adapter for Microsoft.AspNetCore.Identity 2.0 and 3.1. Allows you to use MongoDb instead of SQL server with Microsoft.AspNetCore.Identity 2.0 and 3.1.
Covered by 737 integration tests and unit tests from the modified Microsoft.AspNetCore.Identity.EntityFrameworkCore.Test test suite.
Supports both netstandard2.1 and netcoreapp3.1.
Available as a Nuget package : https://www.nuget.org/packages/AspNetCore.Identity.MongoDbCore/
Install-Package AspNetCore.Identity.MongoDbCore
If you have found this project helpful, either as a library that you use or as a learning tool, please consider buying Alex a coffee:
Your user and role entities must inherit from MongoIdentityUser<TKey> and MongoIdentityRole<TKey> in a way similar to the IdentityUser<TKey> and the IdentityRole<TKey> in Microsoft.AspNetCore.Identity, where TKey is the type of the primary key of your document.
Here is an example:
public class ApplicationUser : MongoIdentityUser<Guid>
{
public ApplicationUser() : base()
{
}
public ApplicationUser(string userName, string email) : base(userName, email)
{
}
}
public class ApplicationRole : MongoIdentityRole<Guid>
{
public ApplicationRole() : base()
{
}
public ApplicationRole(string roleName) : base(roleName)
{
}
} The Id field is automatically set at instantiation, this also applies to users inheriting from MongoIdentityUser<int>, where a random integer is assigned to the Id. It is however not advised to rely on such random mechanism to set the primary key of your document. Using documents inheriting from MongoIdentityRole and MongoIdentityUser, which both use the Guid type for primary keys, is recommended. MongoDB ObjectIds can optionally be used in lieu of GUIDs by passing a key type of MongoDB.Bson.ObjectId, e.g. public class ApplicationUser : MongoIdentityUser<ObjectId>.
MongoDB collection names are set to the plural camel case version of the entity class name, e.g. ApplicationUser becomes applicationUsers. To override this behavior apply the CollectionName attribute from the MongoDbGenericRepository nuget package:
using MongoDbGenericRepository.Attributes;
namespace App.Entities
{
// Name this collection Users
[CollectionName("Users")]
public class ApplicationUser : MongoIdentityUser<Guid>
{
...To add the stores, you can use the IdentityBuilder extension like so:
services.AddIdentity<ApplicationUser, ApplicationRole>()
.AddMongoDbStores<ApplicationUser, ApplicationRole, Guid>
(
"mongodb://localhost:27017",
"MongoDbTests"
)
.AddDefaultTokenProviders();It is also possible to share a common IMongoDbContext across your services (requires https://www.nuget.org/packages/MongoDbGenericRepository/):
var mongoDbContext = new MongoDbContext("mongodb://localhost:27017", "MongoDbTests");
services.AddIdentity<ApplicationUser, ApplicationRole>()
.AddMongoDbStores<IMongoDbContext>(mongoDbContext)
.AddDefaultTokenProviders();
// Use the mongoDbContext for other things.You can also use the more explicit type declaration:
var mongoDbContext = new MongoDbContext("mongodb://localhost:27017", "MongoDbTests");
services.AddIdentity<ApplicationUser, ApplicationRole>()
.AddMongoDbStores<ApplicationUser, ApplicationRole, Guid>(mongoDbContext)
.AddDefaultTokenProviders();
// Use the mongoDbContext for other things.Alternatively a full configuration can be done by populating a MongoDbIdentityConfiguration object, which can have an IdentityOptionsAction property set to an action you want to perform against the IdentityOptions (Action<IdentityOptions>).
The MongoDbSettings object is used to set MongoDb Settings using the ConnectionString and the DatabaseName properties.
The MongoDb connection is managed using the mongodb-generic-repository, where a repository inheriting IBaseMongoRepository is registered as a singleton. Look at the ServiceCollectionExtension.cs file for more details.
var mongoDbIdentityConfiguration = new MongoDbIdentityConfiguration
{
MongoDbSettings = new MongoDbSettings
{
ConnectionString = "mongodb://localhost:27017",
DatabaseName = "MongoDbTests"
},
IdentityOptionsAction = options =>
{
options.Password.RequireDigit = false;
options.Password.RequiredLength = 8;
options.Password.RequireNonAlphanumeric = false;
options.Password.RequireUppercase = false;
options.Password.RequireLowercase = false;
// Lockout settings
options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(30);
options.Lockout.MaxFailedAccessAttempts = 10;
// ApplicationUser settings
options.User.RequireUniqueEmail = true;
options.User.AllowedUserNameCharacters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789@.-_";
}
};
services.ConfigureMongoDbIdentity<ApplicationUser, ApplicationRole, Guid>(mongoDbIdentityConfiguration)
.AddDefaultTokenProviders();To run the tests, you need a local MongoDb server in default configuration (listening to localhost:27017).
Create a database named MongoDbTests for the tests to run.
