How to accept POST submission with token or user id/pwd

Followed a few examples on the net and found that if I try with curl command as below it returns a long html string which I don’t understand. Tried save that to a HTML file but when opened with IE/Chrome, the content is blank…

$ curl -H “Authorization: Token xxxxxxxxxxxxxx” https://xxxxxxx.wixsite.com/test1/testing

<meta charset="utf-8"/>
