调试ASP.Net Core 2.1时自动登录

asp.net-core-identity asp.net-core-mvc .net-core asp.net-core c#

我正在尝试在我构建的ASP.net core 2.1应用程序上自动登录以进行调试。

获取错误:

HttpContext不能为null。

Startup.cs 文件

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

        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });

        app.UseCookiePolicy();

        CreateRoles(ServiceProvider).Wait();

        if (env.IsDevelopment())
        {
            DeveloperLogin(ServiceProvider).Wait();
        }
    }


    private async Task DeveloperLogin(IServiceProvider serviceProvider){

        var UserManager = serviceProvider.GetRequiredService<UserManager<User>>();
        var signInManager = serviceProvider.GetRequiredService<SignInManager<User>>();

        var _user = await UserManager.FindByNameAsync("test@gmail.com");

        await signInManager.SignInAsync(_user, isPersistent: false);

    }

这是我不久前提出的关于Mac上Windows身份验证的另一个问题的扩展。由于应用程序的性质,我添加了角色管理的核心标识,即使应用程序仍然只使用Windows Auth。

堆栈跟踪:

    System.AggregateException: "One or more errors occurred. (HttpContext must not be null.)" 
---> System.Exception {System.InvalidOperationException}: "HttpContext must not be null."
    at Microsoft.AspNetCore.Identity.SignInManager`1.get_Context()
    at Microsoft.AspNetCore.Identity.SignInManager`1.SignInAsync(TUser user, AuthenticationProperties authenticationProperties, String authenticationMethod)
    at myApp.Startup.DeveloperLogin(IServiceProvider serviceProvider) in /Users/user/Documents/Repositories/myApp/myApp/Startup.cs:135

对于 HttpContext ,它仅在http请求管道期间存在。没有 请求上下文 在里面 Configure

供使用 Identity ,您需要使用 app.UseAuthentication(); .

使用sigin with遵循以下步骤 .

配置请求管道。

    app.UseAuthentication();
    if (env.IsDevelopment())
    {
        app.Use(async (context, next) =>
        {
            var user = context.User.Identity.Name;
            DeveloperLogin(context).Wait();
            await next.Invoke();
        });
    }

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });

你需要打电话 app.UseAuthentication();

DeveloperLogin

    private async Task DeveloperLogin(HttpContext httpContext)
{

    var UserManager = httpContext.RequestServices.GetRequiredService<UserManager<IdentityUser>>();
    var signInManager = httpContext.RequestServices.GetRequiredService<SignInManager<IdentityUser>>();

    var _user = await UserManager.FindByNameAsync("Tom");

    await signInManager.SignInAsync(_user, isPersistent: false);

}
