分享一下我老师大神的人工智能教程吧。零基础！通俗易懂！风趣幽默！还带黄段子！希望你也加入到我们人工智能的队伍中来！http://www.captainbed.net
最近做了一个在线支付,哎呀,把我给折腾的可不轻.搞了很长时间. PayPal 是一家 eBay 公司，它是在线付款解决方案的全球领导者，在全世界有超过七千一百六十万个帐户用户。PayPal 可由易趣买家和卖家、在线零售商和其他商家在 56 个市场以 6 种货币使用：加元 欧元 英镑 美元 日元 澳元；PayPal 快速、安全而又方便，是跨国交易的理想解决方案。国内的支付宝和PayPal 类型是差不多的！
随着制作外贸网站的数量增多，有些客户针对国外需要用到PayPal 支付接口，今天找了些PayPal 支付接口方面的资料，以备以后查询！也可以点GO去看原文档.
1.到https://developer.paypal.com注册一个开发帐号，好了之后再进入Sandbox建立测试用的Paypal虚拟帐号（至少应该建立一个Business的和一个Personal的），信息可以是假的,注意:这里的至少两个测试帐号是在你所建立的开发帐号里面建立的,不要注册错了；
2.测试是很麻烦,但是是必不可少的,因为如果客户买过一次出错之后,就不会来第二次了,所以花半天时间做测试是很重要的；
3.代码帖出来给大家参考一下,我做的是不很细,支付成功后返回的结果我就没有做,因为我在测试的时候已经没有问题了,所以没有做,改天有空会完善的；
