IONIC call webservice token

the doc on http get says

get(url, parameters, headers)

and parameters and headers are objects, not strings
so (I can’t find what HttpParams object does)

let params = {
‘SubscriptionID’: ‘3D’,
'SubscriptionPassword’: ‘passx’,
‘BridgeID’: '',
'UserID’, ‘khcadmin’,
‘Password’: ‘P@ssw0rd’,
‘BranchID’: ‘01’,
‘LangID’: ‘en-US’};
this.http.get(‘http://192.168.0.6:81/EBSWebApi/api/login/’, params);
