关键词替换功能
众所周知，PAYPAL直接仿牌的话，如果产品名称有大牌的话，容易被冻结。
所以，关键词替换是PAYPAL多账户轮询中，减少封号的一个必备的重要步骤。
后台管理轮询PAYPAL设置
主要针对独立网站对应哪些PAYPAL，每个PAYPAL要收多少次或者要收多少金额进行匹配。
交易记录功能
后台可以方便的查看订单数量。
我们想看看正常下单的时候，PAYPAL标准支付是进行了哪些数据的提交！
先从一个demo站绑了PAYPAL标准支付进行下单。
我这里以wordpress+woocommerce的系统为例
并且记录下html的对应代码段

然后对应F12查看源码抓发送到paypal的网络记录
先POST到https://bbs.affadsense.com/?wc-ajax=checkout
然后跳转到PAYPAL网址
PAYPAL这段网址去URL ENCODE后，是这样子
https://www.paypal.com/cgi-bin/webscr?cmd=_cart&[email protected]&no_note=1¤cy_code=USD&charset=utf-8&rm=2&upload=1&return=https://bbs.affadsense.com/?page_id=8&order-received=342&key=wc_order_R0h8x24NncmNu&utm_nooverride=1&cancel_return=https://bbs.affadsense.com/?page_id=7&cancel_order=true&order=wc_order_R0h8x24NncmNu&order_id=342&redirect&_wpnonce=660a44ce83&page_style=&image_url=&paymentaction=sale&invoice=WC-342&custom={"order_id":342,"order_key":"wc_order_R0h8x24NncmNu"}¬ify_url=https://bbs.affadsense.com/?wc-api=WC_Gateway_Paypal&first_name=Russell&last_name=Jack&address1=P.O.Box+621&address2=&city=clovis&state=NM&zip=88102&country=US&[email protected]&night_phone_a=362&night_phone_b=693&night_phone_c=5941&no_shipping=1&tax_cart=0.00&item_name_1=ãready+stock+ãS3+Level+Men's+Steel+Toe+Work+Safety+Shoes&quantity_1=1&amount_1=36&item_number_1=32998917949&item_name_2=ãReady+stockã2020++Black+Driving+Mens+Loafers+Moccasins+Breathable+Slip+onShoes&quantity_2=1&amount_2=32&item_number_2=32964786330&bn=WooThemes_Cart
这段就是我们发送给PAYPAL请求付款的几个参数了。
为了好看点，我把这段URL的请求参数转为JSON格式
可以看到，数据把商家的邮箱，就说PAYPAL收款账号，产品名称，用户信息，价格，数量都发到paypal的网关上了。
因为这些参数都是可控的，我们可以做个中间件，或者说俗点，就是中间跳转站，来获取并且修改成我们要返回给PAYPAL的数据。
那么如何获取客户是否付款成功，然后依此来实现账号根据收款次数和收款的金额进行账号轮询收款呢？
这里PAYPAL的返回数据的介绍，大家可以参考下
https://blog.csdn.net/zxl646801924/article/details/80454449
paypal支付交易成功后返回的对象中就有交易信息(包括支付交易ID，支付金额，支付人信息，收款人信息等)，同时如果你开启了消息通知paypal会同时给你推送一条差不多内容的交易信息。
支付成功返回数据
我们在调paypal支付接口(execute)接口支付成功或者失败paypal返回的数据。
id：为本次的数据ID，唯一。
payer：付款人的信息。
transations：支付交易信息。
transations.amount：支付金额信息，总价，税费，运费等。
transations.item_list：商品信息。
transations.shipping_address：收货地址信息。
transations.related_resources：里面就是收款人的信息。
transations.related_resources.state：这个状态就是收款人的交易状态，只要是completed就表示我们收到了钱，钱到账了就什么都好说了，交易成功。

}同时服务器会收到ipn消息， 类似：
支付成功后paypal会同时往我们卖家账号那里配置的消息通知url推送一条消息数据，数据和支付成功大致一样。
由于paypal推送消息不止一次，正常情况下如果是 completed并且用户收到信息就不会再推了，如果推送失败或者交易状态发生改变，比如出现资金冻结，发起退款等事情的时候，paypal的就会有多次推送了，那么我们要怎样判断是第一次推送还是多次推送呢？
查看数据我们发现数据中有交易号txn_id，如果出现多次推送就会多出一个属性parent_txn_id，这个就是原始交易ID，所以我们可以判断有没有这个属性，这个属性有没有值来确定是第一次还是第二次推送。

这个结果测试怎么出来呢？
创建PayPal沙盒模式并测试支付流程

以下是我这边抓取到的ipn测试返回的数据
我们格式化下
可以看到，状态，金额，付款人邮箱，手续费等，都有在返回的数据里。
那么我们就可以根据这些进行比对，然后再通过中间平台进行调配！
