将 PHP 与 Google 串行通知 (IPN) 结合使用

Question

我正在尝试弄清楚如何使用 PHP 来实现这一点。我有一个可用的贝宝 IPN，不到 20 行代码就可以获取我需要的数据。我试过阅读谷歌文档，但它们要么太具体，要么太笼统。有一些示例代码，在 5 个文件中大约有 1300 行，我无法理解。我只需要从已完成的事务中返回一些 var，仅此而已。是否可以用几行代码（我的意思是没有价值 1300 行的“包含”文件）来做到这一点，或者 Google Checkout 的过程真的那么庞大吗？

这是我开始的一些代码。还没有完成。 它完美地工作。 您需要做的就是获取 Google 发回的数据，并将此代码写入文件并使用它插入到您的销售表中，将收到的付款通知发送给客户等等。 诀窍是，当 Google 向您发送帖子时，您必须使用 Authorization 标头进行回调，否则它不会考虑它。

function post2google($url, $timeout = 30, $port = 80, $buffer = 128) {
  $mid = "123456789";
  $mky = "qwertyuiop";
  $aut = base64_encode($mid . ":" . $mky);

  $arr = parse_url($url);

  $ssl = "";
  if($arr['scheme'] == "https") $ssl = "ssl://";

  $post  = "POST " . $arr['path'] . " HTTP/1.1\r\n";
  $post .= "Host: " . $arr['host'] . "\r\n";

  $post .= "Authorization: Basic " . $aut . "\r\n";
  $post .= "Content-Type: application/xml; charset=UTF-8\r\n";
  $post .= "Accept: application/xml; charset=UTF-8\r\n";

  $post .= "Content-Length: " . strlen($arr['query']) . "\r\n";
  $post .= "Connection: Close\r\n";
  $post .= "\r\n";
  $post .= $arr['query'];

  $f = fsockopen($ssl . $arr['host'], $port, $errno, $errstr, $timeout);

  if(!$f)
    return $errstr . " (" . $errno . ")";

  else{
    fputs($f, $post);
    while(!feof($f)) { $echo .= @fgets($f, $buffer); }
    fclose($f);

    return $echo;
  }
}
$re =  post2google("https://checkout.google.com/api/checkout/v2/reportsForm/Merchant/123456789?_type=notification-history-request&serial-number=" . $_REQUEST['serial-number'], 3, 443);

$re = str_replace("&", "\n", $re) . "\n\n--\n\n";

file_put_contents("gpn.txt", $re, FILE_APPEND);

我已经让它工作了，这是我的代码框架，可用于处理 HTTP 通知/响应。这显然是从上面 tntu 的示例中得出的。 （谢谢！）

//incoming data is in the var $_POST['serial-number']
//"send" the response to acknowledge the serial number that google talks about all over but never explains how
echo "_type=notification-acknowledgment&serial-number=".$_POST['serial-number'];

//now we need to call google's server and ask for this transaction's data:
//you'll need to change your merchant id in the $url and $mid vars, and your merchant key in the $mky var
$url = "https://sandbox.google.com/checkout/api/checkout/v2/reportsForm/Merchant/1234567890?_type=notification-history-request&serial-number=" . $_REQUEST['serial-number'];
$mid = "1234567890"; 
$mky = "ABCDEFGHIJK";
$aut = base64_encode($mid . ":" . $mky);

$arr = parse_url($url);
$ssl = "";
if($arr['scheme'] == "https") $ssl = "ssl://";

$post  = "POST " . $arr['path'] . " HTTP/1.1\r\n";
$post .= "Host: " . $arr['host'] . "\r\n";
$post .= "Authorization: Basic " . $aut . "\r\n";
$post .= "Content-Type: application/xml; charset=UTF-8\r\n";
$post .= "Accept: application/xml; charset=UTF-8\r\n";
$post .= "Content-Length: " . strlen($arr['query']) . "\r\n";
$post .= "Connection: Close\r\n";
$post .= "\r\n";
$post .= $arr['query'];

//now we actually make the request by opening a socket and calling Google's server
$f = fsockopen($ssl . $arr['host'], 443, $errno, $errstr, 30);

if(!$f){
    //something failed in the opening of the socket, we didn't contact google at all, you can do whatever you want here such as emailing yourself about it and what you were trying to send, etc
    @mail("troubleshooting@yourdomain.com","Google IPN - HTTP ERROR ",$errstr . " (" . $errno . ")\n\n\n".$arr['query']);
}else{
    //the socket was opened, send the request for the order data: 
    fputs($f, $post); // you're sending
    while(!feof($f)) { $response .= @fgets($f, 128); } //google replies and you store it in $response
    fclose($f); //close the socket, we're done talking to google's server

    $spl=strpos($response,"_type="); //parse the type because parse_str won't catch it
    if ($spl!==false){
        $spl2=strpos($response,"&",$spl);
        $ordertype=substr($response,($spl+6),($spl2-$spl)-6);
    }//$ordertype will tell you which type of notification is being sent, new-order-notification, risk-information-notification, etc
    $subresponse=substr($response,$spl2+1); //put the rest of it into an array for easy access
    parse_str($subresponse,$order);//you can now access google's response in $order[] vars
    //IMPORTANT: dots in Google's field names are replaced by underscore, for example:
    // $order['google-order-number'] and $order['buyer-billing-address_address1'] NOT $order['buyer-billing-address.address1']
    //order field names are shown here: 
    //https://developers.google.com/checkout/developer/Google_Checkout_HTML_API_Notification_API#order_summary

     //this is the point where you will want to use the data contained in $order[] to create a new record in your database or whatever.
    //NOTE: be sure to store and check for duplicates using the google-order-number because you will get multiple notifications from google regarding the same order

    if (strtoupper($order['order-summary_financial-order-state']) == "CHARGEABLE"){
        //CHARGEABLE is what indicates it is safe to create a login for the user (if you are delivering digital goods) 
        // insert into db, and/or email user with key or download url
    }
}
