Question

我尝试了多个不同的IPN类示例，每次paypal都会在IPN模拟器中返回INVALID。

我已经做了一些测试，而我返回到paypal的数据看起来是一样的。例如

paypal发送的内容：

payment_type=echeck&payment_date=Sun%20Jun%2010%202018%2010%3A17%3A15%20GMT%2B0100%20%28GMT%20Summer%20Time%29&payment_status=Completed&address_status=confirmed&payer_status=verified&first_name=John&last_name=Smith&payer_email=buyer@paypalsandbox.com&payer_id=TESTBUYERID01&address_name=John%20Smith&address_country=United%20States&address_country_code=US&address_zip=95131&address_state=CA&address_city=San%20Jose&address_street=123%20any%20street&business=seller@paypalsandbox.com&receiver_email=seller@paypalsandbox.com&receiver_id=seller@paypalsandbox.com&residence_country=US&item_name=something&item_number=AK-1234&quantity=1&shipping=3.04&tax=2.02&mc_currency=USD&mc_fee=0.44&mc_gross=12.34&mc_gross_1=12.34&txn_type=web_accept&txn_id=300182286&notify_version=2.1&custom=xyz123&invoice=abc1234&test_ipn=1&verify_sign=undefined

我发送的Paypal

cmd=_notify-validate&payment_type=echeck&payment_date=Sun%20Jun%2010%202018%2010%3A17%3A15%20GMT%2B0100%20%28GMT%20Summer%20Time%29&payment_status=Completed&address_status=confirmed&payer_status=verified&first_name=John&last_name=Smith&payer_email=buyer@paypalsandbox.com&payer_id=TESTBUYERID01&address_name=John%20Smith&address_country=United%20States&address_country_code=US&address_zip=95131&address_state=CA&address_city=San%20Jose&address_street=123%20any%20street&business=seller@paypalsandbox.com&receiver_email=seller@paypalsandbox.com&receiver_id=seller@paypalsandbox.com&residence_country=US&item_name=something&item_number=AK-1234&quantity=1&shipping=3.04&tax=2.02&mc_currency=USD&mc_fee=0.44&mc_gross=12.34&mc_gross_1=12.34&txn_type=web_accept&txn_id=300182286&notify_version=2.1&custom=xyz123&invoice=abc1234&test_ipn=1&verify_sign=undefined

Paypal回复：'INVALID'

我目前使用的代码是：

public function verifyIPN()
{
    if ( ! count($_POST)) {
        throw new Exception("Missing POST Data");
    }

    $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) {
            // Since we do not want the plus in the datetime string to be encoded to a space, we manually encode it.
            if ($keyval[0] === 'payment_date') {
                if (substr_count($keyval[1], '+') === 1) {
                    $keyval[1] = str_replace('+', '%2B', $keyval[1]);
                }
            }

            $myPost[$keyval[0]] = urldecode($keyval[1]);
        }
    }

    // Build the body of the verification post request, adding the _notify-validate command.
    $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) {

            $value = rawurlencode(stripslashes($value));
        } else {
            $value = rawurlencode($value);
        }
        // Added this line to see if it helps
        $value = str_replace('%40', '@', $value);
        $req .= "&$key=$value";
    }

    // Post the data back to PayPal, using curl. Throw exceptions if errors occur.
    $ch = curl_init($this->getPaypalUri());
    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_SSLVERSION, 6);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);

    // This is often required if the server is missing a global cert bundle, or is using an outdated one.
    if ($this->use_local_certs) {
        curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . "/cert/cacert.pem");
    }

    curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'User-Agent: PHP-IPN-Verification-Script',
        'Connection: Close',
    ));

    $res = curl_exec($ch);

    if (!($res)) {
        file_put_contents("paypal-errors.txt", "error no: ".$errno($ch)." errorstr: ".curl_error($ch));
        $errno  = curl_errno($ch);
        $errstr = curl_error($ch);
        curl_close($ch);
        throw new Exception("cURL error: [$errno] $errstr");
    }

    $info      = curl_getinfo($ch);
    $http_code = $info['http_code'];

    if ($http_code != 200) {
        file_put_contents("paypal-errors.txt", "error http status response = ".$http_code);
        throw new Exception("PayPal responded with http code $http_code");
    }

    curl_close($ch);
    file_put_contents("paypal-sent.txt", "response: ".file_get_contents('php://input'));
    file_put_contents("paypal-result.txt", "response: ".$res);

    // Check if PayPal verifies the IPN data, and if so, return true.
    if ($res == self::VALID) {
        return true;
    } else {
        return false;
    }
}

所以在这一点上，我假设我的环境有问题。我的服务器有TLS 1.2和1.3。我已经没有用于故障排除的想法了。任何帮助将不胜感激！

Paypal IPN总是返回INVALID - php
