我正在撰写一份有关MVC核心申请的印本。 在此,我使用GET AJAX电话。 www.un.org/Depts/DGACM/index_french.htm 但在向我的当地二等服务器部署之后,我的非洲宇宙航空研究开发机构的呼吁给我留下错误的信息。

任何帮助或建议,为什么要对国际调查局进行这种调查?

 GET http://mycrt.companyName/GitLab/GetRackStatus 500 (Internal Server Error)    jquery.js:10099

在此,我呼吁阿马齐安会

$( #rackInfo ).click(function () {
    var url =  GitLab/GetRackStatus ; //http://mycrt.CompanyName/GitLab/GetRackStatus URL also returns same error
    $.blockUI();
    $.ajax({
        url: url,
        type: "GET",
        success: function (responseHtml) {
            $( #rackInfoResults ).replaceWith(responseHtml);
            $( #rackInfoResultsError ).hide();
            bindEventsOnRacks();
            $.unblockUI();
        },
        error: function (responseHtml) {
            $( #rackInfoResults ).hide();
            $( #rackInfoResultsError ).show();
            $.unblockUI();
        }
    });           
});

这里是我的控制者

public async Task<IActionResult> GetRackStatus()
{
  //Controller code
  return PartialView("_RackStatusPartialView");
}

这里是我的发射场。 json

  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:53400",

注:我曾尝试过AJAX中的URL以下,Gives 我的错误之处如下:

http://localhost/GitLab/GetRackStatus

Access to XMLHttpRequest at  http://localhost/GitLab/GetRackStatus  from origin  http://mycrt.companyName  has been blocked by CORS policy: No  Access-Control-Allow-Origin  header is present on the requested resource.
