header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');

header('Access-Control-Allow-Headers: X-Requested-With, Content-Type, Accept, x-api-key');

header('Test-Header: Rex');

.htaccess

Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type, x-api-key"
Header add Access-Control-Allow-Methods "GET,POST,OPTIONS,DELETE,PUT"

DNS Configurations

Server A -> sub domain -> Server B

目前Domain是指到Server A, 但是想要開一個subdomain指到Server B

取得Server B的IP
在Server B中建一個sub domain
在Server A中建一個sub domain
修改#3 sub domain的A record, 指到#1的IP

GSuit -> Godaddy

如果網址是在gsuite買的，在Gsuite控制台會有地方查詢到網域相關的資料，並且有登入godaddy domain manager的帳密和網址
在Godaddy另外開一個帳號建立網站
#2完成後，在網域的地方可以查到server的IP
在#1的domain manager中，把A record指到#3的IP
