Question

我正在尝试在asp.netcoreapp2.2 mvc this中实现project，但这给了我error。我下载了他们的代码，它符合要求。这里的Request是HttpRequestBase WebpageRenderingPage，在我的项目中似乎不可用

我尝试手动添加System.web.dll，但这不起作用。 PostDetailController.cs中使用的标头

using System;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using MovieBlend.Models;
using MovieBlend.Services;
using PusherServer;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Authorization;
using System.Web;

Index.cshtml

@model MovieData

    ViewData["Title"] = Model.Title;

                    });
            }
        }
    });
</script>

在这行中给我错误

 axios.post('@Url.Action("AddComment", "PostDetail", new {}, protocol: Request.Url.Scheme)', this.comment)

和

 axios.get('@Url.Action("Comments", "PostDetail", new { id = @Model.Id }, protocol: Request.Url.Scheme)')

如何解决这个问题？

Answer 1

您需要在页面顶部添加@page指令，以指示它是razor page。页面顶部应如下所示：

@page
@model MovieData
@{
    ViewData["Title"] = Model.Title;
}

然后，您应该可以访问Request属性。我做了类似的事情（但只是调用Request.Scheme）：

var _url = '@Url.Action("UploadFile", "Data", new { projectId = Model.ID }, Request.Scheme)';

CS0103名称“请求”在当前上下文中不存在
