我想實現paypal IPN監聽器。問題是，無論我嘗試什麼，我仍然從IPN模擬器獲得INVALID答案。我搜索了很多論壇，但沒有任何幫助。有誰知道，可能是什麼問題？PayPal IPN模擬器返回INVALID答案
請參閱下面的代碼。 YII_DEBUG是真的 USE_SANDBOX是真的 我試着用或不用cacert.pem的實現，沒有任何工作。
public function actionProcessPayment()
{
// Read POST data
// reading posted data directly from $_POST causes serialization
// issues with array data in POST. Reading raw POST data from input stream instead.
$raw_post_data = file_get_contents('php://input');
if(YII_DEBUG == true) {
Yii::log(date('[Y-m-d H:i e] '). "Original data: " . $raw_post_data . PHP_EOL, 'warning');
}
$req = 'cmd=_notify-validate&'.$raw_post_data;
// Post IPN data back to PayPal to validate the IPN data is genuine
// Without this step anyone can fake IPN data
if(self::USE_SANDBOX == true) {
$paypal_url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
} else {
$paypal_url = "https://www.paypal.com/cgi-bin/webscr";
