c# - 无法加载资源: the server responded with a status of 500 (Internal Server Error) Azure MVC

Question

我已经制作了 MVC 项目并将其发布到 Azure 。在 IIS 本地服务器中它工作正常，但在 Azure 上，当它路由到删除时，它不会路由到删除 View 并停止在删除操作中，而是显示:

当我打开浏览器的控制台时，会出现此问题消息:

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

这是代码:

Controller :

  public class GroupsController : Controller
            {
        //the rest of the code
               // GET: Groups
                public ActionResult Index()
            {
                List<GroupsModels> groups = GetJsonFile();
                return View(groups);
            }
                    // GET: Groups/Delete/
                [HttpGet]
                public ActionResult Delete(int id,string groupname,string useremail)
                {
                    GroupsModels temp = new GroupsModels
                    {
                        ID = id,
                        Name = groupname,
                        newuser = useremail
                    };
                    return View(temp);
                }
            }

型号:

public class GroupsModels
{
    public GroupsModels()
    {
        this.UserEmail = new List<string>();
    }
    public int ID { get; set; }
    public string Name { get; set; }
    [EmailAddress(ErrorMessage = "Invalid Email Address")]
    public string newuser { get; set; }
    public List<string> UserEmail { get; set; }
}

索引 View :

@model IEnumerable<DashBoard.Models.GroupsModels>

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Roles</h2>


@foreach (var item in Model)
{

    <div class="row  alert-success" style="text-align: center;font-size:large; padding:10px;">
        <div class="col-sm">
            <b> @Html.DisplayFor(modelItem => item.Name) |</b>
            @Html.ActionLink("Add User", "Add", "Groups", new { GroupId = item.ID },null)

        </div>

    </div>

    <div class="row   border-bottom border ">
        @for (int i = 0; i < item.UserEmail.Count(); ++i)
        {

            <div class="col-6 col-md-4  border">
                <b> @Html.DisplayFor(modelItem => item.UserEmail[i])|</b>
                @Html.ActionLink("Delete","Delete","Groups",new { id = item.ID, groupname = item.Name, useremail = item.UserEmail[i] },null)
            </div>
            if (i == 2)
            {

                <div class="w-100"></div>
            }
        }

    </div>

    <br />
}

删除 View :

  @model DashBoard.Models.GroupsModels

@{
    ViewBag.Title = "Delete";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Delete</h2>

<h3>Are you sure you want to delete this?</h3>
<div>
    <h4>GroupsModels</h4>
    <hr />
    <dl class="dl-horizontal">
        <dt>
           <b>Group Name</b>
        </dt>

        <dd>
            @Html.DisplayFor(model => model.Name)
        </dd>

        <dt>
            <B>User Email</B>
        </dt>

        <dd>
            @Html.DisplayFor(model => model.newuser)
        </dd>

    </dl>

    @using (Html.BeginForm()) {
        @Html.AntiForgeryToken()

        <div class="form-actions no-color">
            <input type="submit" value="Delete" class="btn btn-default" /> |
            @Html.ActionLink("Back to List", "Index")
        </div>
    }
</div>

请问有什么问题吗？我该如何解决它？

Answer 1

代码 500 意味着应用程序没有找到您要查找的源，可能是 Controller 或操作名称错误或参数丢失或错误，我认为您应该将 ActionLink 更改为:

@Html.ActionLink("Delete","Delete","Groups",new { id = item.ID, groupname = item.Name, useremail = item.UserEmail[i] })
