How do I config the API in ASP.NET Core for access the http request?

Question

I want to send the data to back-end for creating the details about customers using http post method with API URL. But it refused to connect the back-end. because it need some permission for access the post method. please give some guide line and resolve this error.

i already do some changes in app.setting for Allow-permission-* in back-end side. but nothing happend.

    //This is my ts code

    this.http.post('http://localhost:2401/api/CustomerAPI', 
    jstring).map(res => res.json()).subscribe(data => {
    console.log(data)
  }, (err) => {
    console.log(err)
  });
}

Access to XMLHttpRequest at 'http://localhost:2401/api/CustomerAPI' from origin 'http://localhost:8100' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Then it also show Failed to load resource: net::ERR_CONNECTION_REFUSED

var jstring = JSON.stringify({ CodeId: this.Code, customerNameId: this.CustomerName, ProjectnameId: this.Projectname, SortcodeId: this.Sortcode, contactId: this.contact, AddressId: this.Address, Address2Id: this.Address2, CountryId: this.Country, PostalcodeId: this.Postalcode, PhoneId: this.Phone, FaxId: this.Fax, CheckeboxId: this.Checkebox, DescriptionId: this.Description — , Aug 01 '19 at 07:25

you need to configure your server to allow headers, methods, origins so your client-side app (ionic App) can send requests to your server and get a response.
