PayPal IPN POST 结果为 0 PHP Laravel

Question

I'm struggling with a simple storage script that should be called via PayPal IPN to save the current payment.

I'm using

$input = json_encode($request->all());

$paylog = Paylog::create([
   'data' => $input,
]);

and the result from any incoming POST is always "0".

Where is my fault?

Answer 1

Perhaps you mean to access $_POST

IPN messages should be verified with a postback to ipnpb.paypal.com before doing anything with their contents

IPN is a very old and clunky technology, why are you using it?

To obtain details on a 'current' payment, you should be using an API like v2/checkout/orders to facilitate the checkout. For this you need two routes on your server, one for 'Set Up Transaction' and one for 'Capture Transaction', documented here: https://developer.paypal.com/docs/checkout/reference/server-integration/

The best approval flow to pair with your two routes is https://developer.paypal.com/demo/checkout/#/pattern/server

Answer 2

Solution:

//Make sure encode values to UTF8
$input = json_encode(array_map('utf8_encode',$request->all()));

//And store
$paylog = Paylog::create([
   'data' => $input,
]);

Or to make things a little more efficient:

$paylog = Paylog::create([
   'data' => $json_encode(array_map('utf8_encode',$request->all())),
]);
