SOAP protocol Ionic 2

Hello I need help, I need a SOAP protocol for ionic 2 and Angular 2, I did not find anything current on the internet for ionic 2, my request is as follows something like this:

POST / api HTTP / 1.1
Authorization: Basic dXN1YXJpbzpzZW5oYQ ==
Accept: * / *
Content-Type: text / xml; Charset = utf-8
Content-Length: 281

Ionic is built atop Angular, try looking for solutions with Angular 2 instead. You should have success with that.
