ASP.NET MVC中的简单,硬编码授权,没有复杂的提供程序和数据库

using Microsoft.AspNet.Identity; 
public class AppUser : IUser 
{ 
    //Existing database fields 
    public long AppUserId { get; set; } 
    public long AppUserName { get; set; } 
    public string AppPassword { get; set; } 
    public AppUser() 
    { 
        this.Id = Guid.NewGuid().ToString(); 
    } 
    [Ignore] 
    public virtual string Id { get; set; } 
    [Ignore] 
    public string UserName 
    { 
        get { return AppUserName; } 
        set { AppUserName = value; } 
    } 
}

像这样实现UserStore对象(你必须自定义FindByNameAsync以满足你的需求.这里我展示了一个自定义的db上下文)

using Microsoft.AspNet.Identity;
public class UserStoreService : 
    IUserStore<AppUser>,IUserPasswordStore<AppUser>,IUserSecurityStampStore<AppUser>
{
    CompanyDbContext context = new CompanyDbContext();

    public Task CreateAsync(AppUser user)
    {            
        throw new NotImplementedException();
    }

    public Task DeleteAsync(AppUser user)
    {
        throw new NotImplementedException();
    }

    public Task<AppUser> FindByIdAsync(string userId)
    {
        throw new NotImplementedException();
    }

    public Task<AppUser> FindByNameAsync(string userName)
    {
        Task<AppUser> task = 
        context.AppUsers.Where(apu => apu.AppUserName == userName)
        .FirstOrDefaultAsync();

        return task;
    }

    public Task UpdateAsync(AppUser user)
    {
        throw new NotImplementedException();
    }

    public void Dispose()
    {
        context.Dispose();
    }

    public Task<string> GetPasswordHashAsync(AppUser user)
    {
        if (user == null)
        {
            throw new ArgumentNullException("user");
        }

        return Task.FromResult(user.AppPassword);
    }

    public Task<bool> HasPasswordAsync(AppUser user)
    {
        return Task.FromResult(user.AppPassword != null);
    }

    public Task SetPasswordHashAsync(AppUser user,string passwordHash)
    {
        throw new NotImplementedException();
    }

    public Task<string> GetSecurityStampAsync(AppUser user)
    {
        throw new NotImplementedException();
    }

    public Task SetSecurityStampAsync(AppUser user,string stamp)
    {
        throw new NotImplementedException();
    }
}

如果您有自己的自定义密码哈希,则还需要实现IPasswordHasher.下面是一个没有密码散列的例子(哦不！)

using Microsoft.AspNet.Identity;
public class PasswordHasher : IPasswordHasher
{
    public string HashPassword(string password)
    {
        return password;
    }

    public PasswordVerificationResult VerifyHashedPassword
    (string hashedPassword,string providedPassword)
    {
        if (hashedPassword == HashPassword(providedPassword))
            return PasswordVerificationResult.Success;
        else
            return PasswordVerificationResult.Failed;
    }
}

在Startup.Auth.cs中替换

UserManagerFactory = () => 
    new UserManager<IdentityUser>(new UserStore<IdentityUser>());

同

var userManager = new UserManager<AppUser>(new UserStoreService());
userManager.PasswordHasher = new PasswordHasher();
UserManagerFactory = () => userManager;

在ApplicationOAuthProvider.cs中,将IdentityUser替换为AppUser在AccountController.cs中,将IdentityUser替换为AppUser并删除所有外部身份验证方法,如GetManageInfo和RegisterExternal等.
