asp.net-mvc – PRG模式是否与AJAX表单帖子不兼容？

我们在我们的应用中使用Post-Redirect-Get.这是我们所做工作的本质,它取决于Request.IsAjaxRequest()方法,并将您的视图拆分为.aspx,每个都托管.ascx,以便可以同步和异步(即通过Ajax)调用每个操作.

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit(Foo foo)
{
    try
    {
        // Save the changes to the data store
        unitOfWork.Foos.Attach(foo);
        unitOfWork.Commit();

        if (Request.IsAjaxRequest())
        {
            // The name of the view for Ajax calls will most likely be different to the normal view name 
            return PartialView("EditSuccessAsync");
        }
        else
        {
            return RedirectToAction("EditSuccess");
        }
    }
    catch (Exception e)
    {
        if (Request.IsAjaxRequest())
        {
            // Here you probably want to return part of the normal Edit View
            return PartialView("EditForm",foo);
        }
        else
        {
            return View(foo);
        }
    }
}

我们还有一个轻微的变体,我们专门捕获RulesException(从xVal开始,以便将模型验证错误与其他“更严重”的异常区别对待).

catch (RulesException re)
{
    re.AddModelStateErrors(ModelState,"");

    return View(foo);
}

尽管如此,有时我会怀疑我们可能会略微做错.
