问题
I have seen this question asked a few times, but without any successful answers.
We have a fully functioning desktop checkout utilising PayPal as a payment option. After successfully completing an order, the customer is returned back to our website return_url using the POST return method, as indicated here:
<input type="hidden" name="rm" value="2">
The variables here are only used to identify the order and display relevant information to the customer. IPN is used to actually 'complete' the order in our backend. So far so good.
However, when using a mobile device, PayPal will NOT POST back any data to the return_url whatsoever.
Some answers have suggested setting
<input type="hidden" name="no_note" value="1">
This does nothing.
Has anyone found a way around this? We could rework the return_url for mobile devices, but the data we can send back is limited, so it's not ideal.
TIA
回答1:
It is related to the Safari postback bug. The root cause of the bug is the Negotiate authentication setting under IIS. You have to remove it and leave the NTLM authentication only. But it didn't resolved my problem, but hopefully yours.
