PHP-IPN Paypal“官方”示例代码不起作用
作者：互联网
我有一个问题,我想他们也发现了许多其他问题.我正在尝试将PayPal支付系统集成到我的站点中,但是IPN出现了一些问题.我尝试了此代码,可在github Paypal上找到：
<?php require('PaypalIPN.php');
use PaypalIPN;
$ipn = new PayPalIPN();
// Use the sandbox endpoint during testing.
$ipn->useSandbox();
$verified = $ipn->verifyIPN();
if ($verified) {
}
// Reply with an empty 200 response to indicate to paypal the IPN was received correctly.
header("HTTP/1.1 200 OK");
?>
必修课：
<?php
class PaypalIPN
{
private $use_sandbox = false;
private $use_local_certs = true;
/*
* PayPal IPN postback endpoints
*/
const VERIFY_URI = 'https://ipnpb.paypal.com/cgi-bin/webscr';
const SANDBOX_VERIFY_URI = 'https://ipnpb.sandbox.paypal.com/cgi-bin/webscr';
/*
* Possible responses from PayPal after the request is issued.
*/
const VALID = 'VERIFIED';
const INVALID = 'INVALID';
/**
* Sets the IPN verification to sandbox mode (for use when testing,
* should not be enabled in production).
* @return void
*/
public function useSandbox()
{
$this->use_sandbox = true;
}
/**
* Determine endpoint to post the verification data to.
* @return string
*/
public function getPaypalUri()
{
if ($this->use_sandbox) {
return self::SANDBOX_VERIFY_URI;
} else {
return self::VERIFY_URI;
}
}
/**
* Verification Function
* Sends the incoming post data back to paypal using the cURL library.
*
* @return bool
* @throws Exception
*/
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);
$myPost = [];
foreach ($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';
$get_magic_quotes_exists = false;
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";
}
// 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, ['Connection: Close']);
$res = curl_exec($ch);
$info = curl_getinfo($ch);
$http_code = $info['http_code'];
if ($http_code != 200) {
throw new Exception("PayPal responded with http code $http_code");
}
if ( ! ($res)) {
$errno = curl_errno($ch);
$errstr = curl_error($ch);
curl_close($ch);
throw new Exception("cURL error: [$errno] $errstr");
}
curl_close($ch);
// Check if paypal verfifes the IPN data, and if so, return true.
if ($res == self::VALID) {
return true;
} else {
return false;
}
}
}
当我使用IPN Simulator测试时,得到以下响应：IPN未发送,并且握手未得到验证.请检查您的信息.有人能帮我吗？
解决方法:
从您的示例代码中：
<?php require('PaypalIPN.php');
^^^ /** This will cause your script to fail.**/
在贝宝IPN接受页面上,PHP周围应该没有空格.
如果尚未安装其cacert.pem文件,则需要调整类设置,以使Paypal类cURL不会尝试使用该pem文件：
private $use_local_certs = false; // set to true when you have the
// file in your server filesystem
在IPN模拟器上,您需要选择Web-accept作为要执行的模拟类型.
所需文件是否存在？根据您的代码,该文件应与IPN侦听器文件位于同一文件夹中.是这样吗如果找不到该文件,脚本将失败.
让我们知道这些详细信息是否可以解决此问题,或者您还有其他要添加的细节.
