Asp .Net Core Mvc 2.0网站中的HTTP 500错误

Question

我在Azure中发布了一个ASP.NET Core Mvc 2.0网站。直到今天，当我更新网站时，它都运行良好。由于网站具有社交登录提供商，因此更新包括更改密钥和密码。更新并执行网站后，它在浏览器中显示Http 500错误。

启动文件

public class Startup
{
    private IConfiguration Configuration { get; set; }

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;    
    }
    // This method gets called by the runtime. Use this method to add services to the container.
    // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
    public void ConfigureServices(IServiceCollection services)
    {

        services.AddMvc(options =>
        {
            options.Filters.Add(new RequireHttpsAttribute());
        });
        var users = new Dictionary<string, string> { { "Admin", "Admin@1234" } };
        services.AddSingleton<IUserService>(new UserService(users));

        services.AddAuthentication(options =>
        {
            options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
        })
            .AddFacebook(facebookOptions =>
            {
                facebookOptions.AppId = Configuration["Authentication:Facebook:AppId"];
                facebookOptions.AppSecret = Configuration["Authentication:Facebook:AppSecret"];
            })
            .AddTwitter(options =>
            {
                options.ConsumerKey = Configuration["Authentication:Twitter:ConsumerKey"];
                options.ConsumerSecret = Configuration["Authentication:Twitter:ConsumerSecret"];
            })
            .AddMicrosoftAccount(options =>
            {
                options.ClientId = Configuration["Authentication:Microsoft:ApplicationId"];
                options.ClientSecret = Configuration["Authentication:Microsoft:Password"];
            })
            .AddGoogle(options =>
            {
                options.ClientId = Configuration["Authentication:Google:ClientId"];
                options.ClientSecret = Configuration["Authentication:Google:ClientSecret"];
            })
        .AddCookie(options =>
        {
            options.LoginPath = "/auth/signin";
        });
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseRewriter(new Microsoft.AspNetCore.Rewrite.RewriteOptions().AddRedirectToHttps(301, 44301));
        app.UseStaticFiles();
        app.UseAuthentication();
        app.UseMvc();

    }
}

launchSettings.json文件

 {
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "https://localhost:44301/",
      "sslPort": 44301
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production"
      }
    },
    "IdentityApp": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "applicationUrl": "http://localhost:44301/"
    }
  }
}

我不确定发生了什么，但我怀疑这是一个https问题。代码中没有错误，调试代码后也没有错误。

我被困住了，有人可以帮忙。

谢谢。
