和控制器

        public  HomeController(DBContext context)
        {
            db = context;
        }

        //private readonly ILogger<HomeController> _logger;

        //public HomeController(ILogger<HomeController> logger)
        //{
        //    _logger = logger;
            
        //}
        [HttpGet]
        public IActionResult Index()
        {

            CollectionsData model = new CollectionsData();
            model.Offers = GetOffers();
            model.Services = GetServices();
            model.News = GetNews();
            model.Team = GetSecurityTeam();

            return View(model);
        }

        [HttpPost]
        public IActionResult Contact(ContactUs model)
        {
            db.Contactus.Add(model);
            db.SaveChanges();
            return RedirectToAction("Index");
        
        }

       
   public IActionResult Services( Sevices model)
        {
            var ModelServices = db.Sevices.ToList();
            return View(ModelServices);
        }

        //[ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)]
        //public IActionResult Error()
        //{
        //    return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
        //}


        public IEnumerable<Offers> GetOffers()
        {
            return db.Offers.ToList();
        }

        public IEnumerable<Sevices> GetServices()
        {
            return db.Sevices.ToList();

        }

        public IEnumerable<ourNews> GetNews()
        {
            return db.News.ToList();

        }


        public IEnumerable<SecurityTeam> GetSecurityTeam()
        {
            return db.Team.ToList();

        }

      

    }
}

正确，但是当我删除httppost时，一切都很好，除了将表单发送到数据库，

我不这样做为什么该页面不加载它的给出HTTP错误405

谢谢

Answer 1

您必须在表格的内部放置一个提交按钮

<form asp-controller="Home" asp-action="Contact" method="POST">
    ....your code

    <button type="submit">Contact Us</button>
</form>

，或者出于某种原因有时会更好

@using (Html.BeginForm("Contact", "Home", FormMethod.Post))
{
   ....your code

    <button type="submit">Contact Us</button>
}

，您需要联系，您需要进行诉讼以创建联系人视图

        [HttpGet]
        public IActionResult Contact()
        {
            var model= new ContactUs();
            return View(model)
        }

Answer 2

尝试一下

<form id="contact"  method="POST" asp-action="Contact"> 
  ...     
</form>

Answer 3

返回视图（）从HTTP动词的角度看不到任何意义。您的表格发布正确，但是当您返回视图时，您需要将其更改为重定向到您的获取行动。我不知道您的整个控制器是什么样子，但我怀疑这是命名的问题。

尝试
返回RedirectToAction（“ viewName”）
