MVC认证 - 最简单的方法

问题描述

我已经看过ASP.NET的身份和它看起来非常复杂，难以效仿。基本上我想知道的是授权的登录用户因此[授权]数据注解将允许他们通过最简单的方式。

I have looked at ASP.NET Identity and it looks really complex and difficult to follow. Basically what I want to know is the easiest way to authorize a user on login so the [Authorize] data annotation will allow them through.

推荐答案

请按照下列步骤操作：

安装以下的NuGet包

Install the following NuGet packages

• Microsoft.Owin


• Microsoft.Owin.Host.SystemWeb


• Microsoft.Owin.Security


• Microsoft.Owin.Security.Cookies

App_Start文件夹里，添加一个AuthConfig看起来像这样的：

Inside App_Start folder, add a AuthConfig that look like this:

public static class AuthConfig
{
    public const string DefaultAuthType = "DefaultAppCookie"; //example
    public const string LoginPath = "System/SignIn"; //example

    public static void ConfigureAuth(IAppBuilder app)
    {
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthType,
            LoginPath = new PathString(LoginPath)
        });
    }
}

在项目的根路径，添加一个Startup.cs看起来像这样

In the root path of the project, add a Startup.cs that look like this

[assembly: OwinStartup(typeof(YourPorject.Startup))]
namespace YourPorject
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            AuthConfig.ConfigureAuth(app);
        }
    }

}

要验证的用户（通常是登录动作中）：

To authenticate an user (usually inside a Login Action):

//user = the user that is loggin on, retrieved from database
List<Claim> claims = new List<Claim>
            {
                new Claim(ClaimTypes.Name, user.Name),
                new Claim(ClaimTypes.Email, user.Email),
                //some other claims
            };

ClaimsIdentity identity = new ClaimsIdentity(claims, AuthConfig.DefaultAuthType);
IAuthenticationManager authManager = Request.GetOwinContext().Authentication;
authManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, identity);

您需要添加一个ClaimTypes.Role授权特定的角色。

You need to add a ClaimTypes.Role to authorize specific roles.
