Question

我有以下MVC视图和控制器。当我提交表格时。它传入Id而不是ChangeUserViewModel。

查看：

@model AppTransactionsManagement.Models.ChangeUserViewModel
<div>
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 class="modal-title" id="myModalLabel">Change Password</h4>
    </div>

    @using (Html.BeginForm("ChangePassword", "UsersAdmin", FormMethod.Post))
    {
        @Html.AntiForgeryToken()

        <div class="modal-body">
            <div class="form-horizontal">
                @Html.ValidationSummary(true, "", new { @class = "text-danger" })
                @Html.HiddenFor(model => model.Id)

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

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

            </div>
        </div>
        <div class="modal-footer">
            <div class="form-group">
                <div class="col-md-offset-2 col-md-10">
                    <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
                    <input type="submit" value="Save" class="btn btn-primary" />
                </div>
            </div>
        </div>

    }
</div>

控制器：

 [HttpPost]
        [ValidateAntiForgeryToken]
        private async Task<ActionResult> ChangePassword(ChangeUserViewModel model)
        {
            if (ModelState.IsValid)
            {
                //Get the user manager and user. (if the user is not found, user will be null)
                ApplicationUser user = await UserManager.FindByIdAsync(model.Id);


                if (user == null)
                {
                    return PartialView("_ChangePassword");
                }
                else
                {

                    user.PasswordHash = UserManager.PasswordHasher.HashPassword(model.Password);

                    UserManager.UpdateSecurityStamp(user.Id.ToString());
                    //Save Changes
                    IdentityResult result = await UserManager.UpdateAsync(user);

                    if (result.Succeeded)
                    {
                        return Json(new { success = true });
                    }
                    else
                    {
                        var error = result.Errors.FirstOrDefault();
                        return PartialView("_ChangePassword");

                    }
                }
            }
            return PartialView("_ChangePassword");

        }

型号：

 public class ChangeUserViewModel
    {
        public string Id { get; set; }

        [Required(AllowEmptyStrings = false)]
        [Display(Name = "Email")]
        [EmailAddress]
        public string Email { get; set; }

        [Required]
        [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }
    }

我做错了什么？

Answer 1

您已将方法标记为private，这将使其无法访问。您不能POST使用私有方法。这很可能是你的问题。将其更改为

[HttpPost]
public async Task<ActionResult> ChangePassword(ChangeUserViewModel model)
{
   ......
   ......
}

尝试在控制器操作中使用模型绑定。

public async Task<ActionResult> ChangePassword([Bind(Include = "Id, Email, Password")]ChangeUserViewModel model) {}

MVC表单未提交模型
