【问题描述】：

有一个错误

找不到资源。说明：HTTP 404。

我正在尝试使用 razor 在我的 MVC 中执行 POST 方法。在我的控制器中：

ServiceListController

public ActionResult Index()
{ 
    return View();
}

[HttpPost]
private ActionResult GetData(string txtTech, string txtSerial, string txtJobNo)
{ 
    return View();
}

我使用了 Url.Action。但是当按下按钮过滤器时，Requested URL: /ServiceList/GetData 资源找不到。我需要添加到路线或其他东西吗？

<form action="@Url.Action("GetData", "ServiceList")" method="post">
    @Html.AntiForgeryToken()

    <table style="width: 400px">
            <td>
                @Html.Label("Technician", new { style = "width: 50px;" })
                <input type="text" id="txtTech" name="txtTech" class="form-control" style="width: 200px" />
            </td>
            <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
            <td>
                @Html.Label("Serial", new { style = "width: 50px;" })
                <input type="text" id="txtSerial" name="txtSerial" class="form-control" style="width: 200px" />
            </td>
            <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
            <td>
                @Html.Label("Job No", new { style = "width: 50px;" })
                <input type="text" id="txtJobNo" name="txtJobNo" class="form-control" style="width: 200px" />
            </td>
            <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
            <td>
                @Html.Label("a", new { style = "visibility: hidden;" })
                @Html.DropDownList("txtStatus", new SelectList(Enum.GetValues(typeof(wmssoft_srm.Models.Status))), "Status", new { @class = "form-control", style = "width: 200px;" })
            </td>
        </tr>
        ....
        <tr>
            <td>
                <button class="btn btn-info" type="submit" id="btFilter">Clear Filter</button>
            </td>
        </tr>
    </table>
</form>

【问题讨论】：

因为你[HttpPost]方法是private - 让它public
将 GetData 方法私有 sccess 说明符更改为 public。
@StephenMuecke 非常感谢！没注意。
@AjasAju 你确定吗？
@SeM.Nop.i 编辑了我的答案。这是一个错误的想法。

【解决方案1】：

尝试像这样使用这个 html.beginform 并公开发布方法

 @using (Html.BeginForm("GetData", "ServiceList", FormMethod.Post))
{ @Html.AntiForgeryToken()

<table style="width: 400px">
        <td>
            @Html.Label("Technician", new { style = "width: 50px;" })
            <input type="text" id="txtTech" name="txtTech" class="form-control" style="width: 200px" />
        </td>
        <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
        <td>
            @Html.Label("Serial", new { style = "width: 50px;" })
            <input type="text" id="txtSerial" name="txtSerial" class="form-control" style="width: 200px" />
        </td>
        <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
        <td>
            @Html.Label("Job No", new { style = "width: 50px;" })
            <input type="text" id="txtJobNo" name="txtJobNo" class="form-control" style="width: 200px" />
        </td>
        <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
        <td>
            @Html.Label("a", new { style = "visibility: hidden;" })
            @Html.DropDownList("txtStatus", new SelectList(Enum.GetValues(typeof(wmssoft_srm.Models.Status))), "Status", new { @class = "form-control", style = "width: 200px;" })
        </td>
    </tr>
    ....
    <tr>
        <td>
            <button class="btn btn-info" type="submit" id="btFilter">Clear Filter</button>
        </td>
    </tr>
</table>}

【解决方案2】：

试试这个

服务列表控制器

您的方法已更新

[HttpPost]
[ValidateAntiForgeryToken]
Public ActionResult GetData(string txtTech, string txtSerial, string txtJobNo)
{ 
    return View();
}

更新视图操作你可以尝试两种方法

1)

<form action="@Url.Action("GetData", "ServiceList")" method="post">
    @Html.AntiForgeryToken()

    <table style="width: 400px">
            <td>
                @Html.Label("Technician", new { style = "width: 50px;" })
                <input type="text" id="txtTech" name="txtTech" class="form-control" style="width: 200px" />
            </td>
            <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
            <td>
                @Html.Label("Serial", new { style = "width: 50px;" })
                <input type="text" id="txtSerial" name="txtSerial" class="form-control" style="width: 200px" />
            </td>
            <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
            <td>
                @Html.Label("Job No", new { style = "width: 50px;" })
                <input type="text" id="txtJobNo" name="txtJobNo" class="form-control" style="width: 200px" />
            </td>
            <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
            <td>
                @Html.Label("a", new { style = "visibility: hidden;" })
                @Html.DropDownList("txtStatus", new SelectList(Enum.GetValues(typeof(wmssoft_srm.Models.Status))), "Status", new { @class = "form-control", style = "width: 200px;" })
            </td>
        </tr>
        ....
        <tr>
            <td>
                <button class="btn btn-info" type="submit" id="btFilter">Clear Filter</button>
            </td>
        </tr>
    </table>
</form>

@using (Html.BeginForm("GetData", "ServiceList", FormMethod.Post))
{ 
  @Html.AntiForgeryToken()

<table style="width: 400px">
        <td>
            @Html.Label("Technician", new { style = "width: 50px;" })
            <input type="text" id="txtTech" name="txtTech" class="form-control" style="width: 200px" />
        </td>
        <td>@Html.Label("a", new { style = "visibility: hidden;" })</td>
        <td>
            @Html.Label("Serial", new { style = "width: 50px;" })
            <input type="text" id="txtSerial" name="txtSerial" class="form-control" style="width: 200px" />
        </td>

        <td>
            @Html.Label("a", new { style = "visibility: hidden;" })

        </td>
    </tr>
    ....
    <tr>
        <td>
            <button class="btn btn-info" type="submit" id="btFilter">Clear Filter</button>
        </td>
