Question

cURL Error (28): Operation timed out after 201 milliseconds with 0 bytes received
Here is my code:
if (!isset($_GET['foo'])) {
// Client
$pIds = array("All");
$data = array("apiToken" => "apitoken-3D", "productIds" => $pIds);
$data_string = json_encode($data);
//echo $data_string;
$ch = curl_init('http://myurl/WriteProductData');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
$data = curl_exec($ch);
//var_dump(json_decode($data, true));
$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
curl_close($ch);
if ($curl_errno > 0) {
echo "cURL Error ($curl_errno): $curl_error\n";
} else {
echo "Data received: $data\n";
} else {
// Server
sleep(10);
echo "Done.";
}
Above is not the real API key, etc. but just wanted you to see the code.
Please advise how to troubleshoot this, and what to do to resolve this issue. We can make adjustments on the server if necessary.
