When I made my first paypal script one of the most useful things that I did was to log every piece of information that came through. I just dumped everything into a text file whenever Paypal called the confirmation page. It was incredibly helpfull to see what they were passing over and to debug. Paypal sends a POST of the transaction.
当我制作我的第一个 paypal 脚本时，我所做的最有用的事情之一就是记录通过的每一条信息。每当 Paypal 调用确认页面时，我只是将所有内容都转储到一个文本文件中。查看他们传递的内容并进行调试非常有帮助。Paypal 发送交易的 POST。
$dumpfile = "=== post fields\n";
foreach($_POST as $k=>$v)
$dumpfile .= "[$k] => $v\n";
$dumpfile .= "=== http request headers\n";
foreach(apache_request_headers() as $k=>$v)
$dumpfile .= "[$k] => $v\n";
file_put_contents('pathToAWritableFile', $dumpfile);
I hope this saves you some headache. As a side note, I still keep all the paypal request info in a database in case the purchase logic fails after I update the paypal confirmation script, that has saved me a couple of times.
我希望这可以为您节省一些头痛。作为旁注，我仍然将所有贝宝请求信息保存在数据库中，以防在我更新贝宝确认脚本后购买逻辑失败，这已经为我节省了几次。
