Question

我有一个Html辅助方法，可以在我的控制器上调用Delete方法。

public static MvcHtmlString DeleteEmployeeOtherLeave(this HtmlHelper html, string linkText, Leave _leave)
{
    return html.RouteLink(linkText, "Default",
        new { _employeeOtherLeaveId = _leave.LeaveId, action = "Delete" },
        new { onclick = "$.post(this.href); return false;" });
}

我的控制器上有;

[AcceptVerbs(HttpVerbs.Delete)]
public ActionResult Delete(int _employeeOtherLeaveId)
{
    EmployeeOtherLeaf.Delete(_employeeOtherLeaveId);

    return RedirectToAction("Payroll");
}

但我收到此运行时错误消息;

    System.Web.HttpException: A public action method 'Delete' was not found on controller

Answer 1

在这种情况下，发送正确“DELETE”动词的HTTP请求可能不会调用您的操作。尝试更新AcceptVerbs属性以取代POST。

Answer 2

您正在发送POST请求，而您的控制器操作需要DELETE谓词。所以：

public static MvcHtmlString DeleteEmployeeOtherLeave(this HtmlHelper html, string linkText, Leave _leave)
{
    return html.RouteLink(linkText, "Default",
        new { _employeeOtherLeaveId = _leave.LeaveId, action = "Delete" },
        new { onclick = "$.ajax({url: this.href, type: 'DELETE'}); return false;" });
}

Answer 3

或者您也可以在表单方法属性中更改动词以删除任何一种方法

MVC：System.Web.HttpException：在控制器上找不到公共操作方法“删除”
