当我尝试将app.CreatePerOwinContext(ApplicationRoleManager.Create)添加到configauth时,我被告知applicationRoleManager不存在.有人知道为什么吗？
using Microsoft.Owin.Security.OAuth;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.Owin;
using Microsoft.Owin.Security.Cookies;
using Microsoft.Owin.Security.DataProtection;
using Microsoft.Owin.Security.Google;
using Owin;
using System;
using LaCeibaNetv4.Models;
namespace LaCeibaNetv4
{
public partial class Startup
{
// For more information on configuring authentication,please visit http://go.microsoft.com/fwlink/?LinkId=301864
public void ConfigureAuth(IAppBuilder app)
{
// Configure the db context and user manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
解决方法
我遇到了同样的问题并遇到了这个代码,我曾经将这个类添加到我的项目中：
public class ApplicationRoleManager : RoleManager<IdentityRole>
{
public ApplicationRoleManager(IRoleStore<IdentityRole,string> roleStore)
: base(roleStore) { }
public static ApplicationRoleManager Create(
IdentityFactoryOptions<ApplicationRoleManager> options,IOwinContext context)
{
var manager = new ApplicationRoleManager(
new RoleStore<IdentityRole>(context.Get<ApplicationDbContext>()));
return manager;
}
}
另外,记得在启动时通过在Startup.Auth.cs中添加这段代码来配置它：
app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);
