Why my $.ajax showing “preflight is invalid redirect error”?

Question

I tried the following code in Postman and it was working. Is there something wrong with the code?

$.ajax({
   url: \'http://api.example.com/users/get\',
   t         


        

Answer 1

I received the same error when I tried to call https web service as http webservice.

e.g when I call url 'http://api.example.com/users/get'
which should be 'https://api.example.com/users/get'

This error is produced because of redirection status 302 when you try to call http instead of https.
