asp.net-web-api – 如何自定义认证我自己的表在asp.net web api 2？

public AccountController()
        : this(Startup.UseRMANagerFactory(),Startup.oAuthOptions.AccessTokenFormat)
    {
    }

UseRMANagerFactory = () => 
                new UseRMANager<IdentityUser>(new UserStore<IdentityUser>());

class MYstuFFUserStore<IdentityUser> : UserStore<IdentityUser>
 {
 }

UseRMANagerFactory = () => 
               new UseRMANager<IdentityUser>(new MYstuFFUserStore<IdentityUser>());

假设您的表称为AppUser，将您自己的AppUser域对象转换为IUser(使用Microsoft.AspNet.Identity)，如下所示

using Microsoft.AspNet.Identity;
public class AppUser : IUser
{
    //ExisTing database fields
    public long AppUserId { get; set; }
    public String 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

using Microsoft.AspNet.Identity;
public class UserStoreservice 
         : IUserStore<AppUser>,IUserpasswordStore<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();
    }

}

如果你有自己的自定义密码哈希，你还需要实现IpasswordHasher。下面是一个没有哈希密码的例子(哦不！

using Microsoft.AspNet.Identity;
public class MypasswordHasher : IpasswordHasher
{
    public String Hashpassword(String password)
    {
        return password;
    }

    public passwordVerificationResult VerifyHashedpassword
                  (String hashedpassword,String providedpassword)
    {
        if (hashedpassword == Hashpassword(providedpassword))
            return passwordVerificationResult.@R_674_6048@s;
        else
            return passwordVerificationResult.Failed;
    }
}

在Startup.Auth.cs中替换

UseRMANagerFactory = () => 
     new UseRMANager<IdentityUser>(new UserStore<IdentityUser>());

与

UseRMANagerFactory = () => 
     new UseRMANager<AppUser>(new UserStoreservice()) { passwordHasher = new MypasswordHasher() };

在ApplicationOauthprovider.cs中，将IdentityUser替换为AppUser

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