                t1=ConfigurationSettings.AppSettings["interface"];//支付接口,就是给的一个连接地址
                t2=ConfigurationSettings.AppSettings["account"];//支付宝帐户你的帐户
                t3=ConfigurationSettings.AppSettings["password"];//安全校验码,设置的商家验证码
                t4="images/logo_zfbsmall.gif";//按钮图片地址
                t5="test";//悬停说明
                cmd="0001";//默认
                subject="item";//商品名称
                body="decrip";//描述
                order_no=;//定单号,用户自己生成,方便自己管理                prices=100;//价格0.01~50000.00
                rurl="http://.xxx./";//商品展示网址
                types="1";//1:商品购买2:服务购买3:网络拍卖4:捐赠
                number="1";//购买数量
                transport="3";//1:平邮2:快递3:虚拟物品
                ordinary_fee="";//平邮运费
                express_fee="";//快递运费
                readonlys="true";//交易信息是否只读
                buyer_msg="";//买家给卖家的留言
                buyer="";//买家Email
                buyer_name="";//买家姓名
                buyer_address="";//买家地址
                buyer_zipcode="";//买家邮编
                buyer_tel="";//买家电话号码
                buyer_mobile="";//买家手机号码
                partner=ConfigurationSettings.AppSettings["partenid"];//合作伙伴ID,这个是固定的

    上面就是要提供得基本信息,然后就是生成支付宝得连接,也就是给支付宝提供一条带验证的购买信息。

    这个函数就是返回生成的地址,里面注释掉的看你自己需要可以添加进去,然后就是md5码的问题,现在用默认的md5生成程序对中文的支持只限于GB2312,而支付宝使用的是GBK,虽然两个编码的内容GBK兼容GB2312但是毕竟两个编码方式不同,所以会产生错误,如果用英文或者数字不会有问题。上面下载里面带的一个md5.asp的算法支持中文。
            现在已经可以跳转到支付宝的页面了,而我们这边就要自己记录用户的信息已经生成的定单编号,这样在支付宝返回信息的时候来查询。在设定了返回地址后,我们就要看接收页面了。

                string ResponseTxt="";
       

                returnTxt            = "N";
                alipayNotifyURL        = ConfigurationSettings.AppSettings["interfaceback"];//支付宝查询接口地址
                myalipayEmail        = ConfigurationSettings.AppSettings["account"];//填写您的支付宝帐号

       
                //检查支付宝通知接口传递过来的参数是否合法
                msg_id            = newop.DelStr(Request["msg_id"]);
                order_no        = newop.DelStr(Request["order_no"]);
                gross            = newop.DelStr(Request["gross"]);
                buyer_email        = newop.DelStr(Request["buyer_email"]);

                    if((ResponseTxt == "true")||(ResponseTxt == "false"))
                    {
                        //更新数据在商户系统里的订单数据;如果已经发货,则将returnTxt置为Y,否则为N
