I am using angular CLI.
How to delete the token param name and value?

let params = new HttpParams();
    params = params.append('siteId', 1);
    params = params.append('orgId', 2);
    params = params.append('token', 3);

This is my code so far:

validate(email) { 
  let params = new HttpParams(); 
  params = params.set('email', email); 
  params = params.set('siteId', this._global.SITEID); 
  params = params.set('orgId', this._global.ORGID); 
  params = params.set('domainName', this._global.DOMAIN_NAME); 
  params = params.set('token', this._global.getRandomUuid()); 
  params.delete('domainName',this._global.DOMAIN_NAME); 
  return this.api.call('member/duplicate', params); 
} 

call(url, params) { 
  // here I want to delete the token param name and value. 
}

params.delete:

Construct a new body with either the given value for the given parameter removed, if a value is given, or all values for the given parameter removed if not.

Example:

params = params.delete('token');

Just writing params.delete('token') will not update the params object because params is immutable. The delete method does not modify the original object, but constructs new object with the param deleted.
