Can't run the curl demo



I’m trying to use smssync,
I’d like first to make the demo working,
I add copied the code from the developer page into a file ( 755 ) demo.php, I only added <?php on the first line

curl -v -H "Expect: " -X POST http://localhost/iot/demo.php -F “from=+000-000-0000” -F “message=sample text message” -F “secret=123456” -F “device_id=1” -F “sent_timestamp=123456789” -F “message_id=80”

  • About to connect() to localhost port 80 (#0)
  • Trying ::1… Connexion refusée
  • Trying… connected
  • Connected to localhost ( port 80 (#0)

POST /iot/demo.php HTTP/1.1
