ASP .NET CORE 2.2的JWT&声明网站的身份验证 [英] ASP .NET CORE 2.2 JWT & Claims identity Authentication for Website

问题描述

我有一个.net core 2.2 api，该API生成(成功登录后)一个JWT令牌，该令牌包含声明身份，身份声明身份传递诸如身份验证用户的用户名，权限和角色之类的信息.

在我的.net core 2.2中.网络应用程序中，我有一个登录机制，该机制可以通过控制器的用户检索JWT令牌.

我的问题是

如何从我的登录控制器内部扩展令牌并设置Web应用程序以包括对User.Identity.IsAuthenticated，User.IsInRole("Admin")之类的身份验证机制以及[Authorize]和[Authorize(Roles="Admin")]

我一直被引导着查看外部身份验证提供程序(例如facebook/google)背后的源代码，但无济于事.

谢谢.

解决方案

第一步是在Startup.cs中使用cookie authentication:

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie();

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

在Configure方法中，使用UseAuthentication方法来调用设置HttpContext.User属性的身份验证中间件.在调用UseMvcWithDefaultRoute或UseMvc之前，先调用UseAuthentication方法:

app.UseAuthentication();

然后在您的auth控制器中，获取令牌并进行解码以获取声明后，您应该创建新的ClaimsIdentity，添加声明并登录用户:

if (!User.Identity.IsAuthenticated)
{
    var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme, ClaimTypes.Name, ClaimTypes.Role);
    identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, YourName));
    identity.AddClaim(new Claim(ClaimTypes.Name, YourName));
    identity.AddClaim(new Claim(ClaimTypes.Role, "Admin"));

    //Add your custom claims

    var principal = new ClaimsPrincipal(identity);
    await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal, new AuthenticationProperties { IsPersistent = true });

}

之后，您可以使用User.Identity.IsAuthenticated，User.IsInRole("Admin")和[Authorize(Roles="Admin")]:

[Authorize(Roles = "Admin")]
public IActionResult About()
{
    var result = User.IsInRole("Admin");
    return View();
}

I have an .net core 2.2 api which generates (on a successful login) a JWT token which contains a claims identity that passes along information such as the username, permissions and roles of the authenticated user.

In my .net core 2.2. web app I have a login mechanism which retrieves the JWT token via the user of a controller.

My question is.

How can I expand the token from within my login controller and set up my web app to include the use of the authentication mechanisms like User.Identity.IsAuthenticated, User.IsInRole("Admin") and controller actions like [Authorize] and [Authorize(Roles="Admin")]

I've been directed towards looking at the source code behind external authentication providers such as facebook/google but to no avail.

Thanks in advance.

解决方案

First step is to use cookie authentication in Startup.cs :

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie();

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

In the Configure method, use the UseAuthentication method to invoke the Authentication Middleware that sets the HttpContext.User property. Call the UseAuthentication method before calling UseMvcWithDefaultRoute or UseMvc:

app.UseAuthentication();

Then in your auth controller , after getting token and decode to get the claims , you should create new ClaimsIdentity , add your claims and sign-in user :

if (!User.Identity.IsAuthenticated)
{
    var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme, ClaimTypes.Name, ClaimTypes.Role);
    identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, YourName));
    identity.AddClaim(new Claim(ClaimTypes.Name, YourName));
    identity.AddClaim(new Claim(ClaimTypes.Role, "Admin"));

    //Add your custom claims

    var principal = new ClaimsPrincipal(identity);
    await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal, new AuthenticationProperties { IsPersistent = true });

}

After that , you can useUser.Identity.IsAuthenticated, User.IsInRole("Admin") and [Authorize(Roles="Admin")]:

[Authorize(Roles = "Admin")]
public IActionResult About()
{
    var result = User.IsInRole("Admin");
    return View();
}
