ASP.NET Core Url.Action返回空字符串 [英] ASP.NET Core Url.Action return empty string

问题描述

3个小时后，在stackoverflow上浏览后，我没有找到解决问题的方法.所以我怀疑我的项目中有什么特别之处.

After 3 hours browsing on stackoverflow I don't find solution of my problem. So I suspect something in my project is special.

我在Visual Studios 2017上有一个ASP.NET Core(2.0)WebApplications项目.我尝试从Kalender.cshtml文件进行ajax调用:

I have a ASP.NET Core (2.0) WebApplications Project on Visual Studios 2017. I try to make a ajax call from my Kalender.cshtml file:

return $.ajax({
    type: 'GET',
    url: myurl,
    data: '{}',
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (result) {        //REQUEST SUCCESS
        alert(result);
    },

带有myurl:

var myurl = '@Url.Action("EventsRead","Kalender")';

但是我知道 alert(myurl)返回一个空字符串.因此，ajax调用必须失败.我猜网址应该是这样的:

but I recognize that alert(myurl) return an empty string. So the ajax call must fail. I guess the url should something like:

/Kalender/EventsRead

但是，如果我使用此功能，则ajax返回404找不到.

but if I use this, ajax return 404 Not found.

我的Kalender.cshtml.cs动作如下:

My Kalender.cshtml.cs Action looks like:

[HttpGet]
public IActionResult EventsRead()
{
    //DATABASE READOUT        
    var events = DataBase.Events.ToList();
    return new JsonResult(events);
}

PageModel的类如下:

And the class of the PageModel looks like:

public class KalenderModel : PageModel

这是自动生成的所有内容.我尝试了大约100种不同的版本，但从未在 EventsRead()操作中插入断点.

Here is everything auto generated. I try about 100 different version but never get a breakpoint into the EventsRead() action.

边信息:

在我的Startup.cs中，我取消了AntiforgeryToken:

In my Startup.cs I suppress AntiforgeryToken:

services.AddMvc().AddRazorPagesOptions(options =>
{
    options.Conventions.ConfigureFilter(new IgnoreAntiforgeryTokenAttribute());
});

在发疯之前，我真的需要一些帮助，感谢您的答复.马丁

I really need some help before I get insane, thankful for any response. Martin

推荐答案

对解决方案感兴趣的每个人:

Everybody who interested into the solution:

我在Startup.cs中进行了更改:

I changed in Startup.cs:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //ROUTES DEFAULT SETTINGS
        app.UseMvc();
    }

收件人:

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //ROUTES CUSTOM SETTINGS
        app.UseMvcWithDefaultRoute();
    }

在此之后

'@Url.Action("TestGet","Kalender")'

将返回正确的路径.

现在我上床哭泣.
