Paypal IPN集成到PHP [英] Paypal IPN Integration into PHP

问题描述

我无法获取Paypal的IPN集成到我的PHP，我有以下脚本，它继续下降到默认情况下，在Paypal沙箱中进行付款。

任何帮助将不胜感激！

  $ request =cmd = _notify-validate; 
 foreach（$ _POST as $ varname => $ varvalue）{
 $ email。=$ varname：$ varvalue\\\
; 
 if（function_exists（'get_magic_quotes_gpc'）and get_magic_quotes_gpc（））{
 $ varvalue = urlencode（stripslashes（$ varvalue））; 
} 
 else {
 $ value = urlencode（$ value）; 
} 
 $ request。=& $ varname = $ varvalue; 
} 
 $ ch = curl_init（）; 
 curl_setopt（$ ch，CURLOPT_URL，https://www.sandbox.paypal.com/cgi-bin/webscr）; 
 //curl_setopt($ch,CURLOPT_URL,\"https://www.paypal.com）; 
 curl_setopt（$ ch，CURLOPT_POST，true）; 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ request）; 
 curl_setopt（$ ch，CURLOPT_FOLLOWLOCATION，false）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; 
 $ result = curl_exec（$ ch）; 
 curl_close（$ ch）; 
 
 switch（$ result）{
 caseVERIFIED：
 mail（'[e-mail]'，'worked'，'worked'）; 
 break; 
 caseINVALID：
 mail（'[e-mail]'，'invaild'，'invaild'）; 
 break; 
默认值：
 mail（'[e-mail]'，'failed'，'failed'）; 
} 
  

如果我给自己发电子邮件$ result只是空白。

编辑：我发现它是我的LAMP的服务器端问题，但不确定如何解决它。

注意

解决方案

我建议使用curl安装在服务器上，但我不知道是否配置正确。使用位于此处的var_dump和Paypal测试工具进行一些调试： https：/ /developer.paypal.com/cgi-bin/devscr?cmd=_ipn-link-session

我可以理解，工作时会变得困难和耗时与第三方服务。

可能值得抓取POST数据，序列化它并将其应用到一个变量，所以你可以测试没有PayPal打回你的回调。 p>

我最初会这样做，以获取PayPal POST。

 <？php 
 file_put_contents（serialize（$ _ POST），'post.log'）; 
 //现在你有post请求序列化，我们可以抓取内容，并将其应用到一个变量进行快速测试。 
？> 
  

代码开始：

 <？php 
 $ _POST = unserialize（file_get_content（'post.log'））; 
 //现在你可以通过命令行或浏览器执行脚本，而不需要PayPal的测试工具。使用var_dump调查问题是什么。 
 $ request =cmd = _notify-validate; 
 foreach（$ _POST as $ varname => $ varvalue）{
 $ email。=$ varname：$ varvalue\\\
; 
 if（function_exists（'get_magic_quotes_gpc'）and get_magic_quotes_gpc（））{
 $ varvalue = urlencode（stripslashes（$ varvalue））; 
} 
 else {
 $ value = urlencode（$ value）; 
} 
 $ request。=& $ varname = $ varvalue; 
} 
？> 
  

现在：这是一个更有效和高效的测试。在你的例子中，你通过电子邮件发送自己，但不包括邮件功能正文中的任何地方的$ result。

PayPal的IPN示例使用fsock，虽然CURL更有效，更易于使用。也有一些最近的问题，PayPal的沙盒的变化。 https://www.paypal-community.com/t5/Selling-on-your-website/IPN-response-problem/mp/519862/message-uid/519862#U519862

另外：要确定主要原因是什么，正如你所说的，它似乎是你的LAMP堆栈。检查你的日志目录（一般是/ var / log /）一般从他们你可以找出什么失败。

I am having trouble getting Paypal's IPN integrated into my php, i have the following script and it keeps falling through to the default case when a payment is made in the paypal sandbox.

Any help would be appreciated!

$request = "cmd=_notify-validate"; 
    foreach ($_POST as $varname => $varvalue){
        $email .= "$varname: $varvalue\n";  
        if(function_exists('get_magic_quotes_gpc') and get_magic_quotes_gpc()){  
            $varvalue = urlencode(stripslashes($varvalue)); 
        }
        else { 
            $value = urlencode($value); 
        } 
        $request .= "&$varname=$varvalue"; 
    } 
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL,"https://www.sandbox.paypal.com/cgi-bin/webscr");
    //curl_setopt($ch,CURLOPT_URL,"https://www.paypal.com");
    curl_setopt($ch,CURLOPT_POST,true);
    curl_setopt($ch,CURLOPT_POSTFIELDS,$request);
    curl_setopt($ch,CURLOPT_FOLLOWLOCATION,false);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
    $result = curl_exec($ch);
    curl_close($ch);

    switch($result){
        case "VERIFIED":
                    mail('[e-mail]','worked','worked');
            break;
        case "INVALID":
            mail('[e-mail]','invaild','invaild');
            break;
        default:
            mail('[e-mail]','failed','failed');
    }

if i email myself $result it is just blank.

EDIT: I found out it is a server-side issue with my LAMP but am unsure of how to fix it.

Note: i do have curl installed on the server, but i am not sure if it is configured properly.

解决方案

I'd suggest doing some debugging using var_dump and Paypal's test tool located here: https://developer.paypal.com/cgi-bin/devscr?cmd=_ipn-link-session

I can understand it becomes difficult and time consuming when working with Third Party Services.

It may be worth simply grabbing the POST data, serializing it and applying it to a variable so you can test without PayPal hitting your callback.

I'd do something like this initially to grab the PayPal POST.

<?php
   file_put_contents(serialize($_POST), 'post.log');
   //Now you have the post request serialized we can grab the contents and apply it to a variable for fast testing.
?>

Start of your code:

<?php
    $_POST = unserialize(file_get_content('post.log'));
    //Now you can execute the script via command line or within your browser without requiring PayPal's testing tool. Use var_dump to investigate what's the issue.
    $request = "cmd=_notify-validate"; 
    foreach ($_POST as $varname => $varvalue){
        $email .= "$varname: $varvalue\n";  
        if(function_exists('get_magic_quotes_gpc') and get_magic_quotes_gpc()){  
            $varvalue = urlencode(stripslashes($varvalue)); 
        }
        else { 
            $value = urlencode($value); 
        } 
        $request .= "&$varname=$varvalue"; 
    }
?>

NOW: This is a bit more effective and efficient when it comes to testing. In your example you were emailing yourself, but not including $result anywhere within the body of the mail function. http://php.net/manual/en/function.mail.php

PayPal's IPN example uses fsock, although CURL is more effective and easier to use. Also there have been some recent issues with PayPal's sandbox changing. https://www.paypal-community.com/t5/Selling-on-your-website/IPN-response-problem/m-p/519862/message-uid/519862#U519862

Also : To determine what the main cause is, as you've said it appears to be your LAMP stack. Check your logs directory (generally /var/log/) generally from their you'll be able to pinpoint what's failing.
