I'm trying to reproduce a post that works on the postman in the angular, however, when I send the header it gives an error, however, I make a request to the same server to obtain the token without adding the header and it works

Try send post in angular and return message:

This method get an Token, work fine, look not send header...
This method return error, with headerâ¦
