支付接口谁能给啊 比如要用支付宝接口，你就得去他公司申请的
------解决方案--------------------------------------------------------
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；
