PAYPAL IPN自定义字段丢失 [英] PAYPAL IPN custom field missing
问题描述
我在使用API流程和沙箱实现Paypal定期付款时遇到了麻烦. 我成功创建了订阅按钮，并将用户重定向到贝宝快速结帐页面. 但是在贝宝(Paypal)生成的某些IPN中缺少自定义字段，我确实需要此字段.
I'm facing troubles implementing paypal recurring payment with the API process and the sandbox. I succeed to create the subscription button and redirect the user to the paypal express checkout page. But the custom field is missing in some IPN generated by paypal and I really need this field.
这是我在生成订阅按钮时发送的请求:
Here are the requests I send while generating the subscription button:
METHOD=SetExpressCheckout
&VERSION=94.0
&PWD=123456
&USER=myEmail@biz.com
&SIGNATURE=mySignature
&PAYMENTREQUEST_0_AMT=5.00

&PAYMENTREQUEST_0_CUSTOM=custom_var1%3Dvalue1%7Ccustom_var2%3Dvalue2
用户确认交易后，他将返回我的网站，我必须验证信息并创建重复的配置文件. 这是我的要求:
After the user has confirmed the transaction, he is coming back to my website and I have to verify the informations and to create the recurring profil. Here are the requests I do :
METHOD=GetExpressCheckoutDetails
&VERSION=94.0
&PWD=123456

&PAYMENTREQUEST_0_CUSTOM=custom_var1%3Dvalue1%7Ccustom_var2%3Dvalue2
完成此操作后，我将收到以下IPN:
After doing this I receive these IPN :

正如您在第一个IPN中看到的那样，自定义字段可用，但在第二个IPN中不可用. 有谁知道我在第二个IPN中检索自定义字段所缺少的内容?
As you can see in the 1st IPN the field custom is available but not in the second one. Does anyone know what I'm missing for retrieving the custom field in the 2nd IPN ?
推荐答案
您的DoExpressCheckoutPayment请求包含自定义参数，这就是为什么要为该交易取回它的原因.您的CreateRecurringPaymentsProfile请求不包含自定义参数，因此不会返回.
Your DoExpressCheckoutPayment request includes the custom parameter which is why you're getting it back for that transaction. Your CreateRecurringPaymentsProfile request does not have a custom parameter included, so it would not come back.
也就是说，CRPP无法使用自定义参数，因此您需要将数据保存在本地，并将本地记录ID包含在CRPP请求的PROFILEREFERENCE参数中.这样，它将像rp_invoice_id一样在IPN中返回，就像Matt Cole所建议的那样，您可以相应地使用该记录ID将自定义数据从数据库中拉回.
That said, it doesn't look like the custom parameter is available to CRPP so you'll need to save your data locally and include your local record ID in the PROFILEREFERENCE paramter of your CRPP request. This way it will come back in IPN as rp_invoice_id like Matt Cole suggested, and you can pull your custom data back out of your database using that record ID accordingly.
