我是 ASP.net MVC 的新手,目前我正在努力完成这项工作。我有一个名为的控制器方法Add
,它看起来像这样:
public ActionResult Add()
{
// check user is authenticated
if (Request.IsAuthenticated)
{
return View();
}
return RedirectToAction("Index", "Home");
}
//
// POST: /Home/Add
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Add(string title, string description, string priority, string color, FormCollection collection)
{
if (ModelState.IsValid)
{
// create instance of todo object
todo obj = new todo();
try
{
// gather fields
obj.priority = Convert.ToInt32(priority);
obj.color = Convert.ToInt32(color);
obj.title = title;
obj.description = description;
todosDataContext objLinq = new todosDataContext();
// get the users id, convert to string and store it
var userid = Membership.GetUser().ProviderUserKey;
obj.userid = userid.ToString();
// save
objLinq.todos.InsertOnSubmit(obj);
objLinq.SubmitChanges();
return RedirectToAction("Index", "Home");
}
catch
{
return View(obj);
}
}
return RedirectToAction("Index", "Home");
}
如果数据通过 POST 发送到该方法,它应该将数据添加到数据库中。这工作正常,一切都正确添加。但是,RedirectToAction
没有触发,并且应用程序在/Home/Add
应该重定向到 时卡在/Home/Index
。然而,视图加载,所以它显示/Home/Index
,但 URL显示/Home/Add
。
这是包含表单的部分视图的副本:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<todo_moble_oauth.Models.todo>" %>
<% using (Html.BeginForm()) { %>
<%: Html.AntiForgeryToken() %>
<%: Html.ValidationSummary(true) %>
<fieldset>
<h3>Title:</h3>
<div class="editor-field">
<input type="text" name="title" />
</div>
<h3>Description:</h3>
<div class="editor-field">
<input type="text" name="description" />
</div>
<h3>Priority:</h3>
<div class="editor-field">
<select name="priority">
<option value="1">Low</option>
<option value="2">Medium</option>
<option value="3">High</option>
</select>
</div>
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<h3>Color:</h3>
<input type="radio" name="color" id="radio-choice-1" value="0" checked="checked" />
<label for="radio-choice-1">None</label>
<input type="radio" name="color" id="radio-choice-2" value="1" />
<label for="radio-choice-2">Red</label>
<input type="radio" name="color" id="radio-choice-3" value="2" />
<label for="radio-choice-3">Blue</label>
<input type="radio" name="color" id="radio-choice-4" value="3" />
<label for="radio-choice-4">Yellow</label>
</fieldset>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
所以数据被发送到数据库并存储,但是重定向被破坏了。
