asp.net - 我在使用asp.net core 2.2应用程序的生产上的facebook登录回调中收到错误500

Question

我的问题主要仅在将应用程序部署在smarterasp.net托管上之后出现。

当尝试登录到Facebook时，将我重定向到Facebook，然后在我接受返回到应用程序所需的权限后，出现了500错误页面
.../身份/帐户/外部登录？处理程序=回调＃=

我试图查看日志，但是即使手动创建了logs文件夹也没有日志出现。

我试图对webconfig进行一些更改，例如从进程中进行到进程外，但无济于事。

返回OnGetCallbackAsync()时，问题出在OnPost()之后。

   public IActionResult OnPost(string provider, string returnUrl = null)
        {
            // Request a redirect to the external login provider.
            var redirectUrl = Url.Page("./ExternalLogin", pageHandler: "Callback", values: new { returnUrl });
            var properties = _signInManager.ConfigureExternalAuthenticationProperties(provider, redirectUrl);
            return new ChallengeResult(provider, properties);
        }

  public async Task<IActionResult> OnGetCallbackAsync(string returnUrl = null, string remoteError = null)
    {
        returnUrl = returnUrl ?? Url.Content("~/");
        if (remoteError != null)
        {
            ErrorMessage = $"Error from external provider: {remoteError}";
            return RedirectToPage("./Login", new {ReturnUrl = returnUrl });
        }
        var info = await _signInManager.GetExternalLoginInfoAsync();
        if (info == null)
        {
            ErrorMessage = "Error loading external login information.";
            return RedirectToPage("./Login", new { ReturnUrl = returnUrl });
        }

        // Sign in the user with this external login provider if the user already has a login.
        var result = await _signInManager.ExternalLoginSignInAsync(info.LoginProvider, info.ProviderKey, isPersistent: false, bypassTwoFactor : true);
        if (result.Succeeded)
        {
            _logger.LogInformation("{Name} logged in with {LoginProvider} provider.", info.Principal.Identity.Name, info.LoginProvider);
            return LocalRedirect(returnUrl);
        }
        if (result.IsLockedOut)
        {
            return RedirectToPage("./Lockout");
        }
        else
        {
            // If the user does not have an account, then ask the user to create an account.
            ReturnUrl = returnUrl;
            LoginProvider = info.LoginProvider;
            if (info.Principal.HasClaim(c => c.Type == ClaimTypes.Email))
            {
                Input = new InputModel
                {
                    Email = info.Principal.FindFirstValue(ClaimTypes.Email)
                };
            }
            return Page();
        }
    }

没问题，但是我发布的内置文件有些未完成，有些 Controller 正在缓存参数，但是从Facebook重定向后，缓存就被清除了，并且出现了问题。
