PayPal支付接口参数

这两天一直在弄PayPal支付接口
注册PayPal,进放商家工具,开启返回数据后得到一个KEY,这是用来作数据查询时的KEY
PayPal支持支付完成后数据的返回,以URL形式传递给你一组变量,你再结合KEY来POST请求得到返回的数据
支付提交页
<form action="https://www.paypal.com/cgi-bin/webscr" method="post"><input type="hidden" name="cmd" value="_xclick"><!--以下各行可以更改：--><input type="hidden" name="business" value="paypal帐户"><input type="hidden" name="notify_url" value="处理页面"><input type="hidden" name="return" value="返回页面"><input type="hidden" name="item_name" value="名称"><input type="hidden" name="item_number" value="数量"><input type="hidden" name="amount" value="金额"><!--<input type="hidden" name="amount" value=0.01>--><input type="hidden" name="rm" value="2"><input type="hidden" name="charset" value="GBK"><input type="hidden" name="no_shipping" value="1"><input type="hidden" name="image_url" value="显示的图片"><input type="hidden" name="cancel_return" value="取消后返回的页面"><input type="hidden" name="no_note" value="0"><input type="image" src="按钮图片"name="submit" alt="Make payments with PayPal - it's fast, free and secure!"></form>
在登陆帐号支付后,PayPal转到事先设定好的返回页面,接收参数,重新POST请求数据,取得支付信息

得到的数据是这样的结构,注,此数据是要保留一段时间的
