Question

我想在我的控制器上获取主机地址，其类型为POST。请检查以下控制器示例。请注意，我正在使用asp.net core 2.1

[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult PasswordReset(ResetPassword data)
{
    string myurl = //how can i store http host address on this variable?
    return View()
}

Answer 1

尝试一下：

在控制器中：

string myHostUrl = $"{HttpContext.Request.Scheme}://{HttpContext.Request.Host}";

控制器外部：

public class YourClass 
{
   private readonly IHttpContextAccessor _httpContextAccessor;
   public YourClass(IHttpContextAccessor httpContextAccessor)
   {
      _httpContextAccessor = httpContextAccessor;
   }

   public void YourMethod()
   {
      string myHostUrl = $"{_httpContextAccessor.HttpContext.Request.Scheme}://{_httpContextAccessor.HttpContext.Request.Host}";
   }
}

然后按如下所示在Startup类中注册IHttpContextAccessor：

public void ConfigureServices(IServiceCollection services)
{
    services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

    // Or you can also register as follows

    services.AddHttpContextAccessor();
}

Answer 2

您可以通过访问请求获得

string myurl = $"{this.Request.Scheme}://{this.Request.Host}{this.Request.PathBase}";

Answer 3

//获得完整的主机

string host = Request.Scheme + "://" + Request.Host.Value;

Answer 4

In case, if your application is hosted inside a virtual directory, 

    public class ABC
    {
       private readonly IHttpContextAccessor _httpContextAccessor;
       public ABC(IHttpContextAccessor httpContextAccessor)
         {
            _httpContextAccessor = httpContextAccessor;
         }

       public void GetFullAppHostUrl()
         {
         string fullUrl=  $"{_httpContextAccessor.HttpContext.Request.Scheme}://{_httpContextAccessor.HttpContext.Request.Host}{_httpContextAccessor.HttpContext.Request.PathBase}";
     }
    }
