HTTP GET request changes into OPTIONS while adding headers in angular

Question

I have the same problem in Angular 4

The problem is because the app is at a domain, say `example.com`, different from the domain the service is at, say `api.com`. More details, refer here: https://stackoverflow.com/a/19821851/1850609 — acdcjunior, Aug 08 '17 at 16:24

Its called CORS, it has nothing to do with angular. Read up on the CORS spec, specifically the bit about simple request.

If you do not want the options pre flight request to be triggered you must not add custom headers.

Have a look at this for info in which headers are cors safe:
