如何在MVC3控制器检索HTTPPOST PARAMS？ [英] How does the MVC3 Controller retrieve HTTPPOST params?
问题描述
我不太了解这是如何工作的。
I'm not quite understanding how this works.
传递参数正常工作。但是，当我创造新的领域，只有第一个被检索。
Passing parameters from my entity objects works fine. But when I create new fields, only the first one is retrieved.
型号用户类别：
public class User {
[Key]
public long Uid { get; set; }
[Required]
[StringLength(50, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 4)]
[DataType(DataType.EmailAddress)]
[Display(Name = "Email:")]
public string Email { get; set; }
[Required]
[StringLength(20, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 4)]
[Display(Name = "User Name:")]
public string Username { get; set; }
public string Password { get; set; }
public byte Role { get; set; }
public DateTime Created { get; set; }
}
CSHTML：
CSHTML:
@using (Html.BeginForm( null,
null,
FormMethod.Post,
new { id = "regform" })
) {
@Html.ValidationSummary(true)
<fieldset>
<legend>Register</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Email)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Email)
@Html.ValidationMessageFor(model => model.Email)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Username)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Username)
@Html.ValidationMessageFor(model => model.Username)
</div>
<div class="editor-label">
Password:
</div>
<div class="editor-field">
@Html.Password("pwd")
</div>
<div class="editor-label">
Confirm Password:
</div>
<div class="editor-field">
@Html.Password("confirm")
</div>
<p>
<input type="submit" value="Register" />
</p>
</fieldset>
}
控制器：
[HttpPost]
public ActionResult Register(User user, string pwd, string confirm) {
user.Username = confirm;
user.Created = DateTime.Now;
user.Role = 255;
user.Password = EncryptPassword.Password(pwd);
if (ModelState.IsValid && pwd == confirm) {
db.Users.Add(user);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(user);
}
在哪里我越来越糊涂了，是 PWD 拿起罚款。 确认，从另一方面遗体空。我最初的想法，它是由秩序和确认调用模型只是 conPwd 。如果没有工作，我改变了它的名字确认。它仍然不能正常工作，我无法找到任何解释参数如何将多个被传递给控制器。
Where I'm getting confused, is pwd picks up fine. confirm on the other hand remains null. My initial thought that it was calling by order and confirm in the model was simply conPwd. When that didn't work, I changed it's name to confirm. It still is not working and I can't find anything that explains how multiple parameters are passed to the controller.
编辑：
更新我的code。信不信由你，仅此一点就花了我最多的一天写的，因为我一直在试图理解我在做什么。只是有这么多，当你正在学习的实体参加，LINQ，MVC，ASP.NET和剃刀都在同一时间。基本的C＃是我来到这个知道的唯一部分。 :)
Updated my code. Believe it or not, this alone has taken me most of the day to write because I've been trying to understand what I'm doing. There is just so much to take in when you're learning Entities, LINQ, MVC, ASP.NET and Razor all at the same time. Basic C# is the only part I came in to this knowing. :)
推荐答案
您需要一个强类型看你的 RegisterModel 然后用 HTML。 BeginForm 把数据上传到控制器。
You need a strongly typed view for your RegisterModel then use a Html.BeginForm to post the data to the controller.
型号
// This is the Model that you will use to register users
public class RegisterModel
{
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
[Required]
[DataType(DataType.EmailAddress)]
[Display(Name = "Email address")]
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; }
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
}
查看（CSHTML）
// This is your strongly typed view that will use
// model binding to bind the properties of RegisterModel
// to the View.
@model Trainer.Models.RegisterModel
// You can find these scripts in default projects in Visual Studio, if you are
// not using VS, then you can still find them online
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>
// This is where your form starts
// The "Account" parameter states what controller to post the form to
@using (Html.BeginForm((string)ViewBag.FormAction, "Account")) {
@Html.ValidationSummary(true, "Account creation was unsuccessful. Please correct the errors and try again.")
<fieldset>
<legend>Registration Form</legend>
<ol>
<li>
@Html.LabelFor(m => m.UserName)
@Html.TextBoxFor(m => m.UserName)
@Html.ValidationMessageFor(m => m.UserName)
</li>
<li>
@Html.LabelFor(m => m.Email)
@Html.TextBoxFor(m => m.Email)
@Html.ValidationMessageFor(m => m.Email)
</li>
<li>
@Html.LabelFor(m => m.Password)
@Html.PasswordFor(m => m.Password)
@Html.ValidationMessageFor(m => m.Password)
</li>
<li>
@Html.LabelFor(m => m.ConfirmPassword)
@Html.PasswordFor(m => m.ConfirmPassword)
@Html.ValidationMessageFor(m => m.ConfirmPassword)
</li>
</ol>
<!-- The value property being set to register tells the form
what method of the controller to post to -->
<input type="submit" value="Register" />
</fieldset>
}
控制器
// The AccountController has methods that only authorized
// users should be able to access. However, we can override
// this with another attribute for methods that anyone
// can access
[Authorize]
public class AccountController : Controller
{
// This will allow the View to be rendered
[AllowAnonymous]
public ActionResult Register()
{
return ContextDependentView();
}
// This is one of the methods that anyone can access
// Your Html.BeginForm will post to this method and
// process what you posted.
[AllowAnonymous]
[HttpPost]
public ActionResult Register(RegisterModel model)
{
// If all of the information in the model is valid
if (ModelState.IsValid)
{
// Attempt to register the user
MembershipCreateStatus createStatus;
Membership.CreateUser(model.UserName, model.Password, model.Email, passwordQuestion: null, passwordAnswer: null, isApproved: true, providerUserKey: null, status: out createStatus);
// If the out parameter createStatus gives us a successful code
// Log the user in
if (createStatus == MembershipCreateStatus.Success)
{
FormsAuthentication.SetAuthCookie(model.UserName, createPersistentCookie: false);
return RedirectToAction("Index", "Home");
}
else // If the out parameter fails
{
ModelState.AddModelError("", ErrorCodeToString(createStatus));
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
}
