本篇关键词:实现接口支付 
  它现在这种支付方式比较多象网银在线等使用的方法都是url验证就是通过url参数和一个这些url参数的md5编码来确认这个连接的正确性支付宝在你购买成功后跳转自定义连接的时候会传2次过来,第一次是数据底层请求,第二次是web请求,而只有第一次有验证码,这个只能通过记录下来才看的到,因为两次请求间隔很�绻庀允镜幕白詈蟮慕峁潜坏诙胃哺橇说�所以在接收的时候就要设定接收条件,一种是没有notify_type参数的,一种是有的。
  我们先来看一下创建一个连接地址
  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://www.xxx.com/";//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。
  public string creatAlipayItemURL(string t1,string t2,string t3,string t4,string t5,string cmd,string subject,string body,string order_no,string prices,string rurl,string types,string number,string transport,string ordinary_fee,string express_fee,string readonlys,string buyer_msg,string buyer,string buyer_name,string buyer_address,string buyer_zipcode,string buyer_tel,string buyer_mobile,string partner)
  {
  string itemURL,str2CreateAc,acCode;
  string INTERFACE_URL,sellerEmail,keyCode,imgsrc,imgtitle,AlipayItemURL;
  //初始化各必要变量
  INTERFACE_URL=t1+t2;//支付接口
  sellerEmail=t2;//商户支付宝账户(改成你自己的)
  keyCode=t3;//安全校验码(改成你自己的)
  imgsrc=t4;//支付宝按钮图片
  imgtitle=t5;//按钮悬停说明
  str2CreateAc="cmd" + cmd + "subject" + subject;
  str2CreateAc=str2CreateAc + "body" + body;
  str2CreateAc=str2CreateAc + "order_no" + order_no;
  str2CreateAc=str2CreateAc + "price" + prices;
  //str2CreateAc=str2CreateAc + "url" + rurl;
  str2CreateAc=str2CreateAc + "type" + types;
  str2CreateAc=str2CreateAc + "number" + number;
  str2CreateAc=str2CreateAc + "transport" + transport;
  /*str2CreateAc=str2CreateAc + "ordinary_fee" + ordinary_fee;
  str2CreateAc=str2CreateAc + "express_fee" + express_fee;
  str2CreateAc=str2CreateAc + "readonly" + readonlys;
  str2CreateAc=str2CreateAc + "buyer_msg" + buyer_msg;*/
  str2CreateAc=str2CreateAc + "seller" + sellerEmail;
  /*str2CreateAc=str2CreateAc + "buyer" + buyer;
  str2CreateAc=str2CreateAc + "buyer_name" + buyer_name;
  str2CreateAc=str2CreateAc + "buyer_address" + buyer_address;
  str2CreateAc=str2CreateAc + "buyer_zipcode" + buyer_zipcode;
  str2CreateAc=str2CreateAc + "buyer_tel" + buyer_tel;
  str2CreateAc=str2CreateAc + "buyer_mobile" + buyer_mobile;*/
  str2CreateAc=str2CreateAc + "partner" + partner;
  str2CreateAc=str2CreateAc + keyCode;
  //acCode=FormsAuthentication.HashPasswordForStoringInConfigFile(str2CreateAc,"MD5");
  acCode=this.GetMD5(str2CreateAc,"gb2312");
  itemURL=INTERFACE_URL + "?cmd=" + cmd;
  itemURL=itemURL + "&subject=" + HttpUtility.UrlEncode(subject);
  itemURL=itemURL + "&body=" + HttpUtility.UrlEncode(body);
  itemURL=itemURL + "&order_no=" + order_no;
  itemURL=itemURL + "&price=" + prices;
  //itemURL=itemURL + "&url=" + rurl;
  itemURL=itemURL + "&type=" + types;
  itemURL=itemURL + "&number=" + number;
  itemURL=itemURL + "&transport=" + transport;
  /*itemURL=itemURL + "&ordinary_fee=" + ordinary_fee;
  itemURL=itemURL + "&express_fee=" + express_fee;
  itemURL=itemURL + "&readonly=" + readonlys;
  itemURL=itemURL + "&buyer_msg=" + HttpUtility.UrlEncode(buyer_msg);
  itemURL=itemURL + "&buyer=" + HttpUtility.UrlEncode(buyer);
  itemURL=itemURL + "&buyer_name=" + HttpUtility.UrlEncode(buyer_name);
  itemURL=itemURL + "&buyer_address=" + HttpUtility.UrlEncode(buyer_address);
  itemURL=itemURL + "&buyer_zipcode=" + buyer_zipcode;
  itemURL=itemURL + "&buyer_tel=" + buyer_tel;
  itemURL=itemURL + "&buyer_mobile=" + buyer_mobile;*/
  itemURL=itemURL + "&partner=" + partner;
  itemURL=itemURL + "&ac=" + acCode;
  AlipayItemURL=itemURL;
  return AlipayItemURL;
  }
  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 msg_id,order_no,gross,buyer_email,buyer_name,buyer_address,buyer_zipcode,buyer_tel,buyer_mobile,action,s_date,ac,notify_type;
  string returnTxt;//返回给支付宝通知接口的结果
  string alipayNotifyURL;//支付宝查询接口URL
  string myalipayEmail;//商户的支付宝Email
  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"]);
  buyer_name        = newop.DelStr(Request["buyer_name"]);
  buyer_address    = newop.DelStr(Request["buyer_address"]);
  buyer_zipcode    = newop.DelStr(Request["buyer_zipcode"]);
  buyer_tel        = newop.DelStr(Request["buyer_tel"]);
  buyer_mobile    = newop.DelStr(Request["buyer_mobile"]);
  action            = newop.DelStr(Request["action"]);
  s_date            = newop.DelStr(Request["date"]);
  ac                = newop.DelStr(Request["ac"]);
  notify_type     = newop.DelStr(Request["notify_type"]);
  alipayNotifyURL    = alipayNotifyURL + "msg_id=" + msg_id + "&email=" + myalipayEmail + "&order_no=" + order_no;
  System.Net.WebClient isClient= new System.Net.WebClient();
  Stream isStream = isClient.OpenRead(alipayNotifyURL);
  StreamReader isReader = new StreamReader(isStream,System.Text.Encoding.GetEncoding("GB2312"));
  ResponseTxt = isReader.ReadToEnd();
  if(action == "test")//测试商户网站URL是否正确安装
  {
  returnTxt    = "Y";
  }
  else if((action=="sendOff")&&(msg_id!=""))//发货通知
  {
  returnTxt        = "N";
  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
  }
  else
  {
  //非法数据,不做更新
  returnTxt="Error";
  }
  }
  else if((action=="sendOff")&&(notify_type=="web"))
  {
  //检查是否已经付帐,并记录            }
  else if((action=="checkOut")&&(msg_id!=""))//交易结束通知
  {
  returnTxt    = "Y";
  if((ResponseTxt=="true")||(ResponseTxt == "false"))
  {
  //更新数据在商户系统里的订单数据;如果数据更新成功,则将returnTxt置为Y,否则为N
  //更新数据
  //你的代码,更新你这边数据
  returnTxt= "Y";
  }
  else
  {
  //非法数据,不做更新
  returnTxt    = "Error";
  }
  }
  else
  {
  returnTxt="Error";
  }
  Response.Write(returnTxt);
