如何在ASP.Net MVC中将访问者计算机的客户端IP地址保存到数据库？

问题描述：

我试图获得客户端机器的IP地址Request.ServerVariables["HTTP_X_FORWARDED_FOR"];它工作正常。如何在ASP.Net MVC中将访问者计算机的客户端IP地址保存到数据库？

获取IP在页面加载

public ActionResult AddCompany() 
     { 
      get_IP(); 
      return View(); 
     }

get_IP代码

public void get_IP() 
     { 
      string ipAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; 
      if (string.IsNullOrEmpty(ipAddress)) 
      { 
       ipAddress = Request.ServerVariables["REMOTE_ADDR"]; 
      } 
      ViewBag.IPAddress = ipAddress; 
     }

但是，当用户注册的形式获取IP地址的值也保存在数据库..

Cs.html文件

<div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main"> 
    <h1 class="page-header">Add Company</h1> 

    @using (Html.BeginForm()) 
    { 
     @Html.AntiForgeryToken() 

     <div class="form-horizontal"> 
      @Html.ValidationSummary(true) 
      @Html.HiddenFor(model => model.IPAddress) 
      <div class="form-group"> 
       @Html.LabelFor(model => model.CompanyName, new { @class = "control-label col-md-2" }) 
       <div class="col-md-10"> 
        @Html.EditorFor(model => model.CompanyName) 
        @Html.ValidationMessageFor(model => model.CompanyName) 
       </div> 
      </div> 

      <div class="form-group"> 
       @Html.LabelFor(model => model.ShortName, new { @class = "control-label col-md-2" }) 
       <div class="col-md-10"> 
        @Html.EditorFor(model => model.ShortName)

      </div> 

      <div class="form-group"> 
       @Html.LabelFor(model => model.Email, new { @class = "control-label col-md-2" }) 
       <div class="col-md-10"> 
        @Html.EditorFor(model => model.Email) 
        @Html.ValidationMessageFor(model => model.Email) 
       </div> 
      </div> 

      <div class="form-group"> 
       @Html.LabelFor(model => model.Country, new { @class = "control-label col-md-2" }) 
       <div class="col-md-10"> 
        @*@Html.EditorFor(model => model.Country)*@ 
        @Html.DropDownList("Country", null, "---Select Country----") 
        @Html.ValidationMessageFor(model => model.Country) 
       </div> 
      </div> 

      <div class="form-group"> 
       <b>State: </b> 
       <select id="state"></select><br /> 
      </div> 
      <div> 
       <b>City: </b> 
       <select id="city"></select><br /> 
      </div> 
      <div class="form-group"> 
       @Html.LabelFor(model => model.MobileNo, new { @class = "control-label col-md-2" }) 
       <div class="col-md-10"> 
        @Html.EditorFor(model => model.MobileNo) 
        @Html.ValidationMessageFor(model => model.MobileNo) 
       </div> 
      </div> 
      <div class="form-group"> 
       <div class="col-md-offset-2 col-md-10"> 
        <input type="submit" value="Create" class="btn btn-default" /> 
       </div> 
      </div> 
     </div> 
    } 

    <div> 
     @Html.ActionLink("Back to List", "Index") 
    </div> 
</div>

我创建一个隐藏的提交值，但它不工作..

在页面加载ip地址值是显示。之后我点击保存按钮Ip值不会保存到数据库中..

AddCompany

[HttpPost] 
     public ActionResult AddCompany(Company cmp) 
     { 
      using (DataContext entities = new DataContext()) 
      { 
       entities.Company.Add(cmp); 
       entities.SaveChanges(); 
       int id = cmp.CompanyID; 
       Session.Clear(); 
       Response.Redirect("Index"); 
      } 
      return View(cmp); 

     }

任何想法如何从数据库中保存的客户端IP Adrress ..

类文件

[Table("MySecondMVCDemo")] 
    public class Company 
    { 
     [Key] 
     public int CompanyID { get; set; } 
     [Required(ErrorMessage = "Please Enter Company Name")] 
     [Display(Name = "CompanyName")] 
     public string CompanyName { get; set; } 
     [Required(ErrorMessage = "Please Enter Short Name")] 
     [Display(Name = "ShortName")] 
     public string ShortName { get; set; } 
     [Required(ErrorMessage = "Please Enter Email Address")] 
     [Display(Name = "Email")] 
     public string Email { get; set; } 
     [Required(ErrorMessage = "Please Enter Email Address")] 
     [Display(Name = "Country")] 
     public string Country { get; set; } 
     [Required(ErrorMessage = "Please Enter Mobile No")] 
     [Display(Name = "MobileNo")] 
     public string MobileNo { get; set; } 
     public Int32? IPAddress { get; set; } 
    }

答

存储IP地址作为字符串代替的Int32

请使用代码从这里获取IP地址

答

我不知道HiddenFor因为我以前没有使用它。我怎么躲领域是以前是这样的：

@Html.TextBoxFor(model => model.IPAddress, new { @class = "sr-only", @type = "hidden" })

您可以添加引导类SR-只，以确保它是隐藏的。确保您检查您的浏览器检查器以查看隐藏字段是否有值。

如果发布，但仍然没有保存，然后尝试将其保存这样前分配Ip地址身份表单字段值：

cmp.IPAddress = Request.Form["IPAddress"];
