带有存储库和ninject的ASP.NET MVC MembershipProvider

membership-provider ninject asp.net-mvc

Shawn Mclean · 技术社区 · 16 年前

这就是我的应用程序的结构:

存储库(实现中的构造函数采用连接字符串)

public interface IUserRepository
{
    IQueryable<User> GetUsers();
    IQueryable<UserRole> GetUserRoles();
    void InsertUser(User user);
}

服务(构造函数接受用户存储库)

public interface IUserService
{
    User GetUser(int userId);
    User GetUser(string email);
}

用户控制器(我的控制器的一个例子)

public class UsersController : Controller
{
    private IUserService userService;
    public UsersController(IUserService userServ)
    {
        userService = userServ;
    }
}

public class NinjectConfigurationModule : NinjectModule
{

    public override void Load()
    {
        Bind<IUserService>().To<UserService>();
        Bind<IUserRepository>().To<UserRepository>()
            .WithConstructorArgument("connectionString", ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString
            );
    }
}

NinjectControllerFactory公司

public class NinjectControllerFactory : DefaultControllerFactory
{
    private IKernel kernel = new StandardKernel(new NinjectConfigurationModule());

    protected override IController GetControllerInstance(System.Web.Routing.RequestContext requestContext, Type controllerType)
    {
        // We don't want to pass null to ninject as we'll get a strange error.
        return controllerType == null ? null
                                      : (IController)kernel.Get(controllerType);
    }
}

MembershipProvider(这就是我的问题所在)

public class SimpleMembershipProvider : MembershipProvider
{
     //How do I set up User Service here so that ninject can put my connection string here.
     public override bool ValidateUser(string username, string password)
     {
           //Code to use user service.
     }
}

已经回答了问题,但我认为更好的答案是使存储库成为MembershipProvider上的一个属性,并在应用程序启动时注入它。例如

public class AccountMembershipProvider : MembershipProvider
{
    [Inject]
    public IAccountRepository AccountRepository { get; set; }
    ...
}

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);

        // Inject account repository into our custom membership & role providers.
        _kernel.Inject(Membership.Provider);

        // Register the Object Id binder.
        ModelBinders.Binders.Add(typeof(ObjectId), new ObjectIdModelBinder()); 
    }

public override void Initialize(string name, NameValueCollection config) {
    // Validate arguments
    if (config == null) throw new ArgumentNullException("config");

    // Initialize base class
    base.Initialize(name, config);

    // Initialize current class
    this.configuration = config;
    System.Configuration.ConnectionStringSettings ConnectionStringSettings = System.Configuration.ConfigurationManager.ConnectionStrings[config["connectionStringName"]];
    if (ConnectionStringSettings == null || ConnectionStringSettings.ConnectionString.Trim() == "") throw new ProviderException("Connection string cannot be blank.");
    // then you can create a new user service using the connection string: SimpleAuthDb
}

web.config配置

<membership defaultProvider="MyMembershipProvider">
    <providers>
        <clear/>
        <add name="MyMembershipProvider"
             type="Web.SimpleSqlMembershipProvider"
             connectionStringName="SimpleAuthDb" />
    </providers>
</membership>

我还创建了一个像您这样的自定义成员资格提供程序。在用户控制器的登录操作中将调用validateuser函数,如下所示:

Membership.ValidateUser(userName, password);

在里面 ,然后是这样的代码:

userService.ValidateUser(userName, password);

我觉得这更简单。
