Codeigniter paypal_lib IPN无法正常工作

我试图捕获用户在paypal(沙盒)中付款的时间。 IPN就是答案,但似乎我没有得到任何回应。我试图将它放在日志甚至数据库中,但没有数据输入。我知道IPN是一个倾听者,但我不知道为什么不工作..有任何澄清和想法吗?

我正在使用codeigniter Paypal_Lib

这是我的剧本:

首先我宣布了字段

$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,只是通过记录但没有运气来检查它是否有效。

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。

function 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;
}

}

2 个答案:

回答我自己的问题:

无法接收paypal IPN因为连接到paypal时出现问题,修复此问题所要做的就是更改端口:

$fp = fsockopen($url_parsed['host'],'80',$err_num,$err_str,30); 

$fp = fsockopen($url_parsed['host'],'443',$err_num,$err_str,30);

现在已建立接收连接并接收PayPal IPN通知。

后来我发现在沙盒中测试IPN失败了,我发现沙箱中的IPN无法正常工作。您可以参考here

我知道这是一个愚蠢的问题,但你是在本地主机上开发这个吗?在localhost上测试时,PayPal IPN可能无法访问您的服务器。考虑像PageKite,Localtunnel等工具将您的本地计算机放到互联网上,以便PayPal可以访问它。

另一种方法是登录商家沙箱帐户并查看IPN历史记录,以确切了解错误是什么。
