HttpInterceptor with DevExtreme.AspNet.Data doesn't work Angular 6

[pilouk]

Angular 6 here
HttpInterceptor doesn't intercept the call from the DevExtreme.AspNet.Data
The token is not added to the query

Do you guys use HttpClient ?

Must use HttpClient since angular 4.3+

Hello @pilouk

Indeed, currently there's no way to use Angular's HTTP API for AJAX requests.
We plan to improve this (#311).

Here is how you can solve two typical tasks without the use of HttpInterceptor.

Customize a request (URL, headers, query string, HTTP verb)

import * as AspNetData from "devextreme-aspnet-data-nojquery";

const store = AspNetData.createStore({
  // . . .

  onBeforeSend: (operation, ajaxOptions) => {
    ajaxOptions.headers = {
      "Authorization": "..."
    };
  }
});

The members of ajaxOptions are available in the TypeScript declaration.

Redirect to a login form upon receiving Unauthorized response

store["_errorHandler"] = (e: Error) => {
  if (e.message.indexOf("Unauthorized") > -1)
    location.href = "/login";
};
