Asp.Net core 3.0 'value'中的路径必须以'/'开头

Question

我找不到此问题的调用堆栈，看起来控制器一切正常，但“asp-href-include”有问题。

这里是个例外：

    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <meta content="" name="description" />
    <meta content="" name="author" />
    <link asp-href-include="~/bundle/metronic-mandatory.min.css" rel="stylesheet" asp-append-version="true" />
    <link asp-href-include="~/bizz/style/common.min.css" rel="stylesheet" asp-append-version="true" />
    @RenderSection("style", false)

    <script asp-src-include="~/bundle/metronic-mandatory.min.js" asp-append-version="true"></script>
    <script asp-src-include="~/bundle/common.min.js" asp-append-version="true"></script>
    <script asp-src-include="~/bundle/jquery-validation.min.js" asp-append-version="true"></script>
    @RenderSection("script", false)
... other code

控制器（如果需要）

public ViewResult Index()
        {


            return View();
        }

编辑： 也许我忘了提到这个 html 在 _Layout.cshtml 里面。它与问题有什么关系吗？另外，无论我在里面写什么，它都会恢复到原来的样子。

EDIT2：我根据其中一个 cmets 编辑了我的代码。 错误仍然是相同的。 picture

您需要使用 @Url.Content 解析内容 URL，例如：

<script asp-src-include="@Url.Content("~/bundle/metronic-mandatory.min.js")" asp-append-version="true"></script>

Answer 2

我遇到了同样的问题，我认为这是 .NET Core 3 的问题。在此处检查 github 问题 - 在 3.0 中，当在 Scripts 部分中使用 asp-src-includes 标签助手来包含 javascript 文件时，会生成 500 错误。这个标签助手在 2.2 中工作得很好。
