项目需要要在php中使用paypal支付。

先吐槽下paypal，以前做过国内的一些支付接口，有些经验。想到的是直接找paypal客服要接口文档。

尼玛加paypal客服QQ 不在线。几天如此。这么大的支付居然没技术支持，真不能理解。文档后面还是在官网7找8找才找到了。

正文：

首先要在sandbox环境申请主帐号。连接：https://developer.paypal.com/

申请后用主帐号登录申请卖家以及买家帐号。然后进行一些设置。

注意：如果买家是国外的，那么创建买家帐号的时候就要设置所在国家。这样在支付页面才会以该国家的语言显示界面。

申请帐号以及设置问题请参考文档连接：https://www.paypal-biz.com/development/documentation/PayPal_Sandbox_Guide_CN_V2.0.pdf

支付过程首先第一步是提交表单给paypal 当然post方式。

<span style="color: #0000ff;"><span style="color: #800000;">form </span><span style="color: #ff0000;">id</span><span style="color: #0000ff;">="form_starPay"</span><span style="color: #ff0000;"> name</span><span style="color: #0000ff;">="form_starPay"</span><span style="color: #ff0000;"> action</span><span style="color: #0000ff;">="https://www.sandbox.paypal.com/cgi-bin/webscr"</span><span style="color: #ff0000;"> method</span><span style="color: #0000ff;">="post"</span><span style="color: #0000ff;">></span>

当支付成功后 paypal就会跳转到我们设置的 “return” 地址，会带上一个流水号我们get方式就可以取到值。流水号键名 “tx”。

拿到流水号然后加上身份标识跟cmd变量就可以到paypal请求刚才支付的订单的交易内容。

例如：cmd=_notify-synch&tx=123sflsfjlw12&tx_token=fsfljvw3lwejloj43jfvdflf2

cmd=_notify-synch是告诉paypal你要做什么，这里是查询订单交易。

tx_token值要在paypal后台取，刚才注册帐号的时候要开通pdt功能才行。

这个过程paypal称为：PDT (Payment Data Transfer 付款数据传输)。

我们接收到返回的一些数据后就可以进行一些支付后的操作，比如发金币，发货等等。

pdt 详细的返回参数最后给出文档。

为了防止用户关掉浏览器，订单通知不到的情况。paypal还提供了一种通知方式：IPN (Instant Payment Notification 即时付款通知);

IPN 是在后台进行http请求通知。

当开通了ipn功能，并且订单状态发生改变的时候，paypal会主动请求我们支付表单中变量“notify_url”提供的地址。

我们在接收到paypal请求后要拿到所有的数据。

然后用 “cmd=_notify-validate”加上刚才的数据，http发送给paypal进行验证，以防请求是伪造的。

接口对接就这样好了，搞清楚了流程很简单。

如果币种不是paypal默认的，在订单支付后订单状态一直是pending, 用卖家帐号登录在订单状态哪里点击接收，paypal就会自动设置接收该币种功能。
