PayPalのIPN常に無効（PHP）

Question

私は彼らの公式のコード使用して、PayPalのIPNを用IPNリスナー設定にしようとしている：ログ・ファイルで

<?php 
define("DEBUG", 1); 
define("USE_SANDBOX", 1); 
define("LOG_FILE", "./ipn.log"); 

$raw_post_data = file_get_contents('php://input'); 
$raw_post_array = explode('&', $raw_post_data); 
$myPost = array(); 
foreach ($raw_post_array as $keyval) { 
    $keyval = explode ('=', $keyval); 
    if (count($keyval) == 2) 
    $myPost[$keyval[0]] = urldecode($keyval[1]); 
} 

$req = 'cmd=_notify-validate'; 
if(function_exists('get_magic_quotes_gpc')) { 
    $get_magic_quotes_exists = true; 
} 
foreach ($myPost as $key => $value) { 
    if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) { 
    $value = urlencode(stripslashes($value)); 
    } else { 
    $value = urlencode($value); 
    } 
    $req .= "&$key=$value"; 
} 

if(USE_SANDBOX == true) { 
    $paypal_url = "https://www.sandbox.paypal.com/cgi-bin/webscr"; 
} else { 
    $paypal_url = "https://www.paypal.com/cgi-bin/webscr"; 
} 

$ch = curl_init($paypal_url); 
if ($ch == FALSE) { 
    return FALSE; 
} 

curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $req); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); 
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1); 

if(DEBUG == true) { 
    curl_setopt($ch, CURLOPT_HEADER, 1); 
    curl_setopt($ch, CURLINFO_HEADER_OUT, 1); 
} 

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close')); 

$cert = "cacert.pem"; 
curl_setopt($ch, CURLOPT_CAINFO, $cert); 

$res = curl_exec($ch); 
if (curl_errno($ch) != 0) 
    { 
    if(DEBUG == true) { 
    error_log(date('[Y-m-d H:i e] '). "Can't connect to PayPal to validate IPN message: " . curl_error($ch) . PHP_EOL, 3, LOG_FILE); 
    } 
    curl_close($ch); 
    exit; 

} else { 
    if(DEBUG == true) { 
     error_log(date('[Y-m-d H:i e] '). "HTTP request of validation request:". curl_getinfo($ch, CURLINFO_HEADER_OUT) ." for IPN payload: $req" . PHP_EOL, 3, LOG_FILE); 
     error_log(date('[Y-m-d H:i e] '). "HTTP response of validation request: $res" . PHP_EOL, 3, LOG_FILE); 
    } 
    curl_close($ch); 
} 

$tokens = explode("\r\n\r\n", trim($res)); 
$res = trim(end($tokens)); 

if (strcmp ($res, "VERIFIED") == 0) { 
    if(DEBUG == true) { 
    error_log(date('[Y-m-d H:i e] '). "Verified IPN: $req ". PHP_EOL, 3, LOG_FILE); 
    } 
} else if (strcmp ($res, "INVALID") == 0) { 
    if(DEBUG == true) { 
    error_log(date('[Y-m-d H:i e] '). "Invalid IPN: $req" . PHP_EOL, 3, LOG_FILE); 
    } 
} 

?> 

を、それは常に「無効なIPN」と言います。次に、ログファイルの出力例を示します。

私は間違っているようです。私にとっては、たとえ私がサンドボックスモードになっているにもかかわらず、PayPalはその無効を示しているようです。

Answer 1

これは、IPNサンドボックスで間欠的な問題です。 PayPal IPN simulator returning "INVALID" but I've followed the rules
