在应用程序中无法从OwinContext获取UserManager
在应用程序中无法从OwinContext获取UserManager
提问于 2014-06-03 02:48:06
我遵循Microsoft示例，使用Identity 2.0.0实现电子邮件验证
我被困在这部分了
public ApplicationUserManager UserManager
{
get
{
return _userManager ?? HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
}
private set
{
_userManager = value;
}
}这在ApiController.中有效，但HttpContext中不包含任何GetOwinContext方法
所以我尝试了HttpContext.Current.GetOwinContext()，但是GetUserManager方法并不存在。
我想不出一种方法来获得我在Startup.Auth.cs中构建的UserManager
// For more information on configuring authentication, please visit http://go.microsoft.com/fwlink/?LinkId=301864
public void ConfigureAuth(IAppBuilder app)
{
//Configure the db context, user manager and role manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
...
}这一行
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);调用以下函数来配置UserManager
public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
{
var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
//Configure validation logic for usernames
manager.UserValidator = new UserValidator<ApplicationUser>(manager)
{
AllowOnlyAlphanumericUserNames = false,
RequireUniqueEmail = true
};
// Configure user lockout defaults
manager.UserLockoutEnabledByDefault = true;
manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
manager.MaxFailedAccessAttemptsBeforeLockout = 5;
manager.EmailService = new EmailService();
var dataProtectionProvider = options.DataProtectionProvider;
if (dataProtectionProvider != null)
{
manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
}
return manager;
}如何在ApiController中访问此UserManager

我之前真的误解了你的问题。我认为你只是遗漏了一些using语句。
GetOwinContext().GetUserManager<ApplicationUserManager>()在Microsoft.AspNet.Identity.Owin中。
所以试着添加这个部分：
using Microsoft.AspNet.Identity.Owin;
using Microsoft.AspNet.Identity; // Maybe this one too
var manager = HttpContext.Current.GetOwinContext().GetUserManager<UserManager<User>>();Stack Overflow用户

如果您想要对控制器进行单元测试，此扩展方法可能是更好的解决方案。
using System;
using System.Net.Http;
using System.Web;
using Microsoft.Owin;
public static IOwinContext GetOwinContext(this HttpRequestMessage request)
{
var context = request.Properties["MS_HttpContext"] as HttpContextWrapper;
if (context != null)
{
return HttpContextBaseExtensions.GetOwinContext(context.Request);
}
return null;
}用法：
public ApplicationUserManager UserManager
{
get
{
return _userManager ?? Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
}
private set
{
_userManager = value;
}
}Stack Overflow用户

这一行代码拯救了我的一天。
var manager =
new ApplicationUserManager(new UserStore<ApplicationUser>(new ApplicationDbContext()));您可以在控制器操作中使用它来获取UserManager的实例。
