Get Bearer Token from Authorization header

The bearerToken() function is very handy when you are working with apis & want to access the token from Authorization header.

1// Don't parse API headers manually like this:
2$tokenWithBearer = $request->header('Authorization');
3$token = substr($tokenWithBearer, 7);
4 
5//Do this instead:
6$token = $request->bearerToken();
