支付寶Payto接口的c#.net實現

2013-11-13 10:04:24  來源: .NET編程 

  它現在這種支付方式比較多象網銀在線等使用的方法都是url驗證就是通過url參數和一個這些url參數的md編碼來確認這個連接的正確性支付寶在你購買成功後跳轉自定義連接的時候會傳次過來第一次是數據底層請求第二次是web請求而只有第一次有驗證碼這個只能通過記錄下來才看的到因為兩次請求間隔很小如果光顯示的話最後的結果是被第二次覆蓋了的所以在接收的時候就要設定接收條件一種是沒有notify_type參數的一種是有的

  我們先來看一下創建一個連接地址

  t=ConfigurationSettingsAppSettings[interface]//支付接口就是給的一個連接地址

  t=ConfigurationSettingsAppSettings[account]//支付寶帳戶你的帳戶

  t=ConfigurationSettingsAppSettings[password]//安全校驗碼設置的商家驗證碼

  t=images/logo_zfbsmallgif//按鈕圖片地址

  t=test//懸停說明

  cmd=//默認

  subject=item//商品名稱

  body=decrip//描述

  order_no=//定單號用戶自己生成方便自己管理                prices=//價格

  rurl=//商品展示網址

  types=//商品購買服務購買網絡拍賣捐贈

  number=//購買數量

  transport=//平郵快遞虛擬物品

  ordinary_fee=//平郵運費

  express_fee=//快遞運費

  readonlys=true//交易信息是否只讀

  buyer_msg=//買家給賣家的留言

  buyer=//買家Email

  buyer_name=//買家姓名

  buyer_address=//買家地址

  buyer_zipcode=//買家郵編

  buyer_tel=//買家電話號碼

  buyer_mobile=//買家手機號碼

  partner=ConfigurationSettingsAppSettings[partenid]//合作伙伴ID這個是固定的

  上面就是要提供得基本信息然後就是生成支付寶得連接也就是給支付寶提供一條帶驗證的購買信息

  public string creatAlipayItemURL(string tstring tstring tstring tstring tstring cmdstring subjectstring bodystring order_nostring pricesstring rurlstring typesstring numberstring transportstring ordinary_feestring express_feestring readonlysstring buyer_msgstring buyerstring buyer_namestring buyer_addressstring buyer_zipcodestring buyer_telstring buyer_mobilestring partner)

  {

  string itemURLstrCreateAcacCode

  string INTERFACE_URLsellerEmailkeyCodeimgsrcimgtitleAlipayItemURL

  //初始化各必要變量

  INTERFACE_URL=t+t//支付接口

  sellerEmail=t//商戶支付寶賬戶(改成你自己的)

  keyCode=t//安全校驗碼(改成你自己的)

  itemURL=itemURL + &partner= + partner

  itemURL=itemURL + &ac= + acCode

  AlipayItemURL=itemURL

  return AlipayItemURL

  }

  這個函數就是返回生成的地址裡面注釋掉的看你自己需要可以添加進去然後就是md碼的問題現在用默認的md生成程序對中文的支持只限於GB而支付寶使用的是GBK雖然兩個編碼的內容GBK兼容GB但是畢竟兩個編碼方式不同所以會產生錯誤如果用英文或者數字不會有問題上面下載裡面帶的一個mdasp的算法支持中文

  現在已經可以跳轉到支付寶的頁面了而我們這邊就要自己記錄用戶的信息已經生成的定單編號這樣在支付寶返回信息的時候來查詢在設定了返回地址後我們就要看接收頁面了

  string msg_idorder_nogrossbuyer_emailbuyer_namebuyer_addressbuyer_zipcodebuyer_telbuyer_mobileactions_dateacnotify_type

  string returnTxt//返回給支付寶通知接口的結果

  string alipayNotifyURL//支付寶查詢接口URL

  string myalipayEmail//商戶的支付寶Email

  string ResponseTxt=

  returnTxt            = N

  alipayNotifyURL        = ConfigurationSettingsAppSettings[interfaceback]//支付寶查詢接口地址

  myalipayEmail        = ConfigurationSettingsAppSettings[account]//填寫您的支付寶帳號

  //檢查支付寶通知接口傳遞過來的參數是否合法

  msg_id            = newopDelStr(Request[msg_id])

  order_no        = newopDelStr(Request[order_no])

  gross            = newopDelStr(Request[gross])

  buyer_email        = newopDelStr(Request[buyer_email])

  buyer_name        = newopDelStr(Request[buyer_name])

  buyer_address    = newopDelStr(Request[buyer_address])

  buyer_zipcode    = newopDelStr(Request[buyer_zipcode])

  buyer_tel        = newopDelStr(Request[buyer_tel])

  buyer_mobile    = newopDelStr(Request[buyer_mobile])

  action            = newopDelStr(Request[action])

  s_date            = newopDelStr(Request[date])

  ac                = newopDelStr(Request[ac])

  notify_type     = newopDelStr(Request[notify_type])

  alipayNotifyURL    = alipayNotifyURL + msg_id= + msg_id + &email= + myalipayEmail + &order_no= + order_no

  SystemNetWebClient isClient= new SystemNetWebClient()

  Stream isStream = isClientOpenRead(alipayNotifyURL)

  StreamReader isReader = new StreamReader(isStreamSystemTextEncodingGetEncoding(GB))

  ResponseTxt = isReaderReadToEnd()

  if(action == test)//測試商戶網站URL是否正確安裝

  {

  returnTxt    = Y

  }

  else if((action==sendOff)&&(msg_id!=))//發貨通知

  {

  returnTxt        = N

  if((ResponseTxt == true)||(ResponseTxt == false))

  {

  //更新數據在商戶系統裡的訂單數據如果已經發貨則將returnTxt置為Y否則為N

  }

  else

  {

  //非法數據不做更新

  returnTxt=Error

  }

  }

  else if((action==sendOff)&&(notify_type==web))

  {

  //檢查是否已經付帳並記錄            }

  else if((action==checkOut)&&(msg_id!=))//交易結束通知

  {

  returnTxt    = Y

  if((ResponseTxt==true)||(ResponseTxt == false))

  {

  //更新數據在商戶系統裡的訂單數據如果數據更新成功則將returnTxt置為Y否則為N

  //更新數據

  //你的代碼更新你這邊數據

  returnTxt= Y

  }

  else

  {

  //非法數據不做更新

  returnTxt    = Error

  }

  }

  else

  {

  returnTxt=Error

  }

  ResponseWrite(returnTxt)
