因此,我们将RC1应用程序更新为上述最新版本.切换参考数小时后,它开始运行.但是,登录(AccountController/Login)时,出现以下错误:
So, we updated an RC1 app to the latest versions above. After many hours of switching references, it's running. However, when logging in (AccountController/Login), I am getting an error at:
public class AccountController : BaseController
{
public UserManager<ApplicationUser> UserManager { get; private set; }
public SignInManager<ApplicationUser> SignInManager { get; private set; }
private readonly IEmailSender EmailSender;
public AccountController(UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager, IEmailSender emailSender)
{
UserManager = userManager;
SignInManager = signInManager;
EmailSender = emailSender;
}
// GET: /Account/Login
[HttpGet]
[AllowAnonymous]
public IActionResult Login(string returnUrl = null)
{
ViewBag.ReturnUrl = returnUrl;
return View();
}
//
// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Login(ViewModels.Account.LoginViewModel model, string returnUrl = null)
{
if (ModelState.IsValid)
{
// Errs this next line
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, false); // <-- ERRS HERE '.PasswordSignInAsync'
if (result.Succeeded)
return RedirectToLocal(returnUrl);
ModelState.AddModelError("", "Invalid email or password.");
return View(model);
}
// If we got this far, something failed, redisplay form
return View(model);
}
它爆炸并显示以下错误消息:
It blows up with the following error message:
这是Startup.cs:
Here is the Startup.cs:

{
services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));

services.AddEntityFrameworkSqlServer()

});
// Uncomment the following line to add Web API servcies which makes it easier to port Web API 2 controllers.
// You need to add Microsoft.AspNet.Mvc.WebApiCompatShim package to project.json

services.AddTransient<IEmailSender, AuthMessageSender>();
}
// Configure is called after ConfigureServices is called.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
app.UseSession();
// Configure the HTTP request pipeline.

loggerFactory.AddConsole();
loggerFactory.AddDebug();
loggerFactory.AddNLog();

if (env.IsDevelopment())

else

}
env.ConfigureNLog("NLog.config");

app.UseStaticFiles();

这是上下文:
public class ApplicationUser : IdentityUser

// Add Custom Profile Fields
public string Name { get; set; }
}
public class LogManagerContext : IdentityDbContext<ApplicationUser>

public DbSet<LogEventsHistory> LogEventsHistory { get; set; }
public DbSet<LogEventsLineHistory> LogEventsLineHistory { get; set; }
public DbSet<LogRallyHistory> LogRallyHistory { get; set; }
public DbSet<Flag> Flags { get; set; }
protected override void OnModelCreating(ModelBuilder builder)
{
builder.Entity<LogEvent>().HasKey(x => x.LogId);
builder.Entity<LogEvent>().ToTable("LogEvents");
builder.Entity<Client>().HasKey(x => x.ClientId);
builder.Entity<Client>().ToTable("Clients");

builder.Entity<Flag>().ToTable("Flags");
builder.Entity<LogRallyHistory>().HasKey(x => x.HistoryId);
builder.Entity<LogEventsLineHistory>().HasKey(x => x.LineHistoryId);
base.OnModelCreating(builder);
}
推荐答案
错误消息表明您的DbContext
(LogManagerContext
)需要一个接受DbContextOptions
的构造函数.但是我在您的DbContext
中找不到这样的构造函数.因此,在构造函数下面添加内容可能会解决您的问题.
The error message says your DbContext
(LogManagerContext
) needs a constructor which accepts a DbContextOptions
. But i couldn't find such a constructor in your DbContext
. So adding below constructor probably solves your problem.
public LogManagerContext(DbContextOptions options) : base(options)
{
}
编辑评论
如果您未明确注册IHttpContextAccessor
,请使用以下代码:
If you don't register IHttpContextAccessor
explicitly, use below code:
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
