为什么是AspNet.Identity 3.0登录后User.Identity空 [英] Why is User.Identity null after login with AspNet.Identity 3.0

问题描述

我使用DNX RC1内微软AspNet.Identity 3.0框架。随着一些教程的帮助我建立了一个自定义的验证系统。一个成功的密码后查了一些索赔为用户创建和认证将被设置：

  VAR claimsPrincipal =等待SignInManager.CreateUserPrincipalAsync（用户）;
如果（claimsPrincipal = NULL＆放大器;！＆安培;！claimsPrincipal.Identity = NULL）
{
    //设置权利要求向用户
    等待HttpContext.Authentication.SignInAsync（CookieAuthenticationDefaults.AuthenticationScheme，claimsPrincipal）;
    返回RedirectToAction（指数，应用程序）;
}
 

在此登录操作我的浏览器有两个cookie： .AspNet.Cookies 的和的 .AspNet.Microsoft.AspNet.Identity.Application 的

不过，我现在有我的身份有问题。与[授权]注解控制器没有执行。并通过[使用AllowAnonymous]控制器给我一个NullReferenceException因为User.Identity为空：

  [使用AllowAnonymous]
[路线（API /车次）]
公共类TripController：控制器
{[HTTPGET（）]
公共JsonResult获得（）
{
    VAR车次= _repository.GetUserTripsWithStops（User.Identity.Name）;
    ...    返回JSON（结果）;
}
 

有人可以告诉我有什么错我的认证？

当我想，我的错误是某处Startup.cs文件 - 这里是配置方法：

 公共无效配置（IApplicationBuilder应用程序）
{
    app.UseStaticFiles（）;    app.UseIdentity（）;
    app.UseCookieAuthentication（选项=＆GT;
    {
        options.LoginPath =新PathString（/应用程序/登录）;
    }）;    app.UseMvc（路线=＆GT;
    {
        routes.MapRoute（
            名称：默认，
            模板：{控制器} / {行动} / {？ID}
            默认：新{控制器=应用程序，行动=索引}）;
    }）;
}
 

解决方案

感谢上帝，我发现经过一天多的试验和错误的解决方案。最后，我刚刚添加的AutomaticAuthenticate线在Startup.cs文件：

  app.UseCookieAuthentication（选项=＆GT;
{
    options.AutomaticAuthenticate = TRUE;
    options.LoginPath =新PathString（/应用程序/登录）;
}）;
 

I am using Microsofts AspNet.Identity 3.0 framework within the DNX RC1. With the help of some tutorials I have built a custom authentication system. After a successful password check some claims are created for the user and the Authentication will be set:

var claimsPrincipal = await SignInManager.CreateUserPrincipalAsync(user);
if (claimsPrincipal != null && claimsPrincipal.Identity != null)
{
    // Set the claims to the user 
    await HttpContext.Authentication.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, claimsPrincipal);
    return RedirectToAction("Index", "App");
}

After this login action my browser has two cookies: .AspNet.Cookies and .AspNet.Microsoft.AspNet.Identity.Application

However I do have now a problem with my identity. Controllers annotated with [Authorize] are not executed at all. And controllers with [AllowAnonymous] give me a NullReferenceException because User.Identity is null:

[AllowAnonymous]
[Route("api/trips")]
public class TripController : Controller
{

[HttpGet("")]
public JsonResult Get()
{
    var trips = _repository.GetUserTripsWithStops(User.Identity.Name);
    ...

    return Json(results);
}

Can someone please tell me what's wrong with my authentication?

As I guess that my mistake is somewhere in the Startup.cs file - here is the configure method:

public void Configure(IApplicationBuilder app)
{
    app.UseStaticFiles();

    app.UseIdentity();
    app.UseCookieAuthentication(options =>
    {
        options.LoginPath = new PathString("/App/Login");
    });

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller}/{action}/{id?}",
            defaults: new { controller = "App", action = "Index" });
    });
}

解决方案

Thanks god I have found the solution after more than one day trial and error. Finally I just added the AutomaticAuthenticate-line in the Startup.cs file:

app.UseCookieAuthentication(options =>
{
    options.AutomaticAuthenticate = true;
    options.LoginPath = new PathString("/App/Login");
});
