我试图捕捉用户在贝宝(沙盒)中付款的时间。IPN 是这个问题的答案,但似乎我没有得到任何回应。我试图将其放入日志甚至数据库中,但没有数据输入。我知道 IPN 是一个听众,但我不知道为什么不工作.. 对此有任何澄清和想法吗?
我正在使用 codeigniter Paypal_Lib
这是我的脚本:
首先我声明了字段
$this->paypal_lib->add_field('cmd','_cart');
$this->paypal_lib->add_field('upload','1');
$this->paypal_lib->add_field('business', $business_email);
$this->paypal_lib->add_field('return', site_url('invoice/payment_success/'.$invoice_id.'/'.$album_id));
$this->paypal_lib->add_field('cancel_return', site_url('invoice/payment_cancel/'.$invoice_id));
$this->paypal_lib->add_field('notify_url', site_url('invoice/payment_validate/'.$invoice_id)); // <-- IPN url
$this->paypal_lib->add_field('custom', $invoice_id); // <-- Verify return
这是我的 IPN ,只是通过日志检查它是否有效,但没有运气。
public function payment_validate(){
//$this->paypal_lib->dump();
$invoice_id = $this->uri->segment(3);
if ($this->paypal_lib->validate_ipn()){
$payer_email = $this->paypal_lib->ipn_data['payer_email'];
$fp=fopen('temp/logs/paypal_ipn.log','a');
fwrite($fp, $this->paypal_lib->ipn_data . "\n");
fclose($fp); // close file
}
}
这是库中的 validate_ipn。
函数 validate_ipn() {
// get instance
$CI =& get_instance();
// parse the paypal URL
$url_parsed = parse_url($this->paypal_url);
// generate the post string from the _POST vars aswell as load the
// _POST vars into an arry so we can play with them from the calling
// script.
$post_string = '';
#if(count($_POST))
if($_POST)
{
#foreach (array_keys($_POST) as $field)
foreach ($_POST as $field => $value)
{
#$value = $CI->input->post($field, true);
$this->ipn_data[$field] = $value;
$post_string .= $field.'='.urlencode(stripslashes($value)).'&';
}
}
$post_string.='cmd=_notify-validate'; // append ipn command
// open the connection to paypal
$fp = fsockopen($url_parsed['host'],'80',$err_num,$err_str,30);
if(!$fp)
{
// could not open the connection. If loggin is on, the error message
// will be in the log.
$this->last_error = 'fsockopen error no. '.$err_num.': '.$err_str;
$this->log_ipn_results(false);
return false;
}
else
{
// Post the data back to paypal
fputs($fp, "POST $url_parsed[path] HTTP/1.1\r\n");
fputs($fp, "Host: $url_parsed[host]\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ".strlen($post_string)."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $post_string . "\r\n\r\n");
// loop through the response from the server and append to variable
while(!feof($fp))
$this->ipn_response .= fgets($fp, 1024);
fclose($fp); // close connection
}
if (eregi('VERIFIED',$this->ipn_response))
{
// Valid IPN transaction.
if ($this->ipn_log_method == 'db')
{
return $this->log_ipn_results(true);
}
/*// Valid IPN transaction.
$this->log_ipn_results(true);*/
return true;
}
else
{
// Invalid IPN transaction. Check the log for details.
$this->last_error = 'IPN Validation Failed.';
$this->log_ipn_results(false);
return false;
}
