I developed an ionic app but when I execute it from andoid emulator I receive error during server http call.

Failed to load resource: Request header field lang is not allowed by Access-Control-Allow-Headers.

In my request I need to add a custom header field.

This is my request header.

httpHeaders = 
 headers: new HttpHeaders(
 'Content-Type': 'application/json',
 'Access-Control-Allow-Headers': 'lang',
 'lang': this.session.language
 )
 ;

Server side (.htaccess):

Header Set Access-Control-Allow-Origin "*"
Header Set Access-Control-Allow-Headers "*"

If I execute the call via browser or Postman, It works successfully.

In the Postman response header I see:

Server →nginx
Date →Fri, 08 Mar 2019 22:33:08 GMT
Content-Type →application/json;charset=utf-8
Content-Length →79
Connection →keep-alive
Access-Control-Allow-Origin →*
Access-Control-Allow-Headers →*
Access-Control-Allow-Methods →*

Support me please

Thanks
