Registration Sdk
Hello, hope you can help me out. Im trying to get the registration sdk example to work with my server, the first step is to test the server-channel communication, for this on the serverside i created a file named register.php. Which has the functions to generate a new token, and to check if the token is activated on the users table.
On the sdk side,ive only modified the first lines in regScreen.brs as follow:
and here its the script i have on register.php
The first step works half way. Because if you enter the channel, you get the screen with the token, BUT if you click on "get a new code" button, it wont get a new code, and i check on the database and there is a new token updated at least once a second. But never show a new token on screen, also if you hit back, to the main app menu and try to get back in, it wont open any more, i have to exit the channel and enter again. actually this happens even if i dont click on get a new code button.
the second step is not working at all. i have tested the address on my web broswer directly .../register.php?accion=getRegResult®Code=P84R83&deviceID=YU054L463584 and i get the following result:
So i assume the php script is working fine, but nothing happens at the channel, no message, no congratulations page, nothing.
Here is regScreen.brs
I would really appreciate the help as im stuck here for almost 2 weeks. What is wrong with either codes? or anybody has a more complete channel pack for example?
Thanks in advance.
On the sdk side,ive only modified the first lines in regScreen.brs as follow:
m.UrlBase = "http://www.mywebserver.com/roku/linking/register.php"
m.UrlGetRegCode = m.UrlBase + "?accion=getRegCode"
m.UrlGetRegResult = m.UrlBase + "?accion=getRegResult"
m.UrlWebSite = "www.mywebserver.com"
and here its the script i have on register.php
<?
function random_string($length) {
$key = '';
$keys = array_merge(range(0, 9), range('a', 'z'));
for ($i = 0; $i < $length; $i++) {
$key .= $keys[array_rand($keys)];
}
return $key;
}
$con=mysqli_connect("localhost",'user','pass',"db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$serial = htmlspecialchars($_GET['deviceID']);
$action = htmlspecialchars($_GET['accion']);
//Generate token
if($action == 'getRegCode'){
if(!empty($serial)){
//check if the device id is already on db
$query = "SELECT * FROM linking WHERE serial = '$serial'";
if ($result=mysqli_query($con,$query))
{
if(mysqli_num_rows($result) > 0){
//if already exist, update the token at the device id
$info = mysqli_fetch_array($result);
$token = strtoupper(random_string(6));
mysqli_query($con,"UPDATE linking SET token='$token' WHERE serial='$serial'");
}else{
//if new, make new record on db
$token = strtoupper(random_string(6));
mysqli_query($con,"INSERT INTO `linking` (`id`, `serial`, `token`, `used`) VALUES (NULL, '$serial', '$token', '0');");
}
}
?>
<result>
<status>success</status>
<regCode><?=$token?></regCode>
<retryInterval>30</retryInterval>
<retryDuration>900</retryDuration>
</result>
<?
}
//Now check if the token has been activated
}else if($action == 'getRegResult'){
$token = htmlspecialchars($_GET['regCode']);
/* structure
<linkAccount>
<regCode>(current registration code from PreRegistration request)</regCode>
<deviceID>(unique id/serial number for the device)</deviceID>
<deviceTypeID>(opaque string identifying device type)</deviceTypeID>
</linkAccount>
*/
//check if token and device id are in db
$query = "SELECT * FROM users WHERE deviceid = '$serial' AND token='$token'";
if ($result=mysqli_query($con,$query))
{
if(mysqli_num_rows($result) > 0){
echo "<result>
<status>success</status>
<deviceToken>".$token."</deviceToken>
</result>";
}else{
echo "<result> <status>incomplete</status></result>";
}
}
}
?>
The first step works half way.
