ASP.NET MVC:未执行HttpPost的方法

Question

在ASP.NET MVC应用程序中，我有一个文件MessageController.cs，在其中我定义了通过HttpGet和HttpPost访问的EditMessage。通常，用户首先通过HttpGet访问它，然后弹出一个表单，他可以在其中编辑消息，然后单击Save按钮，通过该按钮将调用HttpPost。

我的问题是HttpPost没有被调用。相反，会显示一条错误消息。我有类似的代码来修改数据库的其他部分，使用这些类似的代码，HttpPost就可以工作了。我的问题是为什么它在这里不起作用，我能做些什么来让它起作用。

/// <summary>
/// used by admin only
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
[CustomAuthorization(new[] { GlobalStaticFunc.SecurityOptions.isSUser, GlobalStaticFunc.SecurityOptions.isAdmin })]
[HttpGet]
public async Task<ActionResult> EditMessage(int id)
{
if (PopupController.AnyPopupsInline(User))
{
return RedirectToAction("index", "popup");
}
if (id > 0)
{
BLogic_Entity dbContext = new VMIEntityCreator(true);
var msg = dbContext.GetDbSet<MSG_MESSAGES>().Where(x => x.id == id).FirstOrDefault();
if (msg != null) return View(msg);
}
else if (id == -1)
{
return View(new MSG_MESSAGES() { id = -1 });
}
return View("Messages");
}
[CustomAuthorization(new[] { GlobalStaticFunc.SecurityOptions.isCarrier, GlobalStaticFunc.SecurityOptions.isAdmin, GlobalStaticFunc.SecurityOptions.isSUser })]
[HttpPost]
//        [ValidateAntiForgeryToken]
public async Task<ActionResult> EditMessage(MSG_MESSAGES model)
{
if (PopupController.AnyPopupsInline(User))
{
return RedirectToAction("index", "popup");
}
if (!App_Tools.RightsHandler.IdentityWatcher.CheckUserRights(User.Identity, GlobalStaticFunc.SecurityOptions.isAdmin) && App_Tools.RightsHandler.IdentityWatcher.CheckUserRights(User.Identity, GlobalStaticFunc.SecurityOptions.isEndUser))
{
return RedirectToAction("Messages", "Message");
}
bool isOk = false;
if (model != null)
{
if (!ModelState.IsValid)
{
return View(model);
}
if (model.id > 0)
{
using (TED_BLOGIC.Abstractions.BLogic_Entity usr = new VMIEntityCreator(true))
{
isOk = await usr.UpdateSecurely(usr.GetDbSet<MSG_MESSAGES>().Where(x => x.id == model.id).FirstOrDefault(), model, ModelState);
}
}
}
return View(model);
}

EditMessage.cshtml:的代码

@model TED_BLOGIC.DataBase.DB_MODEL.MSG_MESSAGES
@{
if (Model != null && Model.id > 0)
{
ViewBag.Title = "Message bearbeiten";
}
else
{
ViewBag.Title = "Neue Message anlegen";
}
ViewBag.Ico = "fa-plus";
Layout = "~/Views/Shared/_standardBoxView.cshtml";
}
@using (Html.BeginForm("EditMessage", "Message", new { id = Model.id }, FormMethod.Post, new { data_goback = true }))
{
@Html.AntiForgeryToken()
<div class="panel-body">
<div class="row">
<div class="col-md-12 table-responsive">
@Html.ValidationSummary(false, "", new { @class = "text-danger" })
@Html.EditorForModel("Add/MGV")
<div class="section row mb10">
<div class="form-group">
<div class="col-md-offset-2 col-lg-3 col-md-4 col-sm-5">
<input type="submit" value="Save" class="btn btn-default" onclick=";" /> @*mCust.postToSite(@Url.Action("User", "Admin"));mCust.sendMeBack()*@
</div>
</div>
</div>
</div>
</div>
</div>
}
<script src="~/Scripts/Core/PostbackHandling/OverwritePostbacks.js?v=@GlobalStaticFunc.Version"></script>
<script>
$(document).on("EverythingIsReady", function () {
document.title = 'Cloud - @ViewBag.Title';
})
</script>

Answer 1

<input type="submit" value="Save" class="btn btn-default" onclick=";" />

你能试着去掉按钮的onclick属性吗？

Answer 2

请通过在该post方法上方注释CustomAuthorization属性进行检查，post事件将被触发。我测试了你的代码。
