C#的支付寶Payto接口代碼

2010-08-28 10:53:02來(lái)源:西部e網(wǎng)作者:

  它現(xiàn)在這種支付方式比較多象網(wǎng)銀在線等使用的方法都是url驗(yàn)證,就是通過(guò)url參數(shù)和一個(gè)這些url參數(shù)的md5編碼來(lái)確認(rèn)這個(gè)連接的正確性,支付寶在你購(gòu)買成功后跳轉(zhuǎn)自定義連接的時(shí)候會(huì)傳2次過(guò)來(lái),第一次是數(shù)據(jù)底層請(qǐng)求,第二次是web請(qǐng)求,而只有第一次有驗(yàn)證碼,這個(gè)只能通過(guò)記錄下來(lái)才看的到,因?yàn)閮纱握?qǐng)求間隔很小,如果光顯示的話最后的結(jié)果是被第二次覆蓋了的。所以在接收的時(shí)候就要設(shè)定接收條件,一種是沒(méi)有notify_type參數(shù)的,一種是有的。
 
  我們先來(lái)看一下創(chuàng)建一個(gè)連接地址

  t1=ConfigurationSettings.AppSettings["interface"];//支付接口,就是給的一個(gè)連接地址

  t2=ConfigurationSettings.AppSettings["account"];//支付寶帳戶你的帳戶

  t3=ConfigurationSettings.AppSettings["password"];//安全校驗(yàn)碼,設(shè)置的商家驗(yàn)證碼

  t4="images/logo_zfbsmall.gif";//按鈕圖片地址

  t5="test";//懸停說(shuō)明

  cmd="0001";//默認(rèn)

  subject="item";//商品名稱

  body="decrip";//描述

  order_no=;//定單號(hào),用戶自己生成,方便自己管理                prices=100;//價(jià)格0.01~50000.00

  rurl="商品展示網(wǎng)址

  types="1";//1:商品購(gòu)買2:服務(wù)購(gòu)買3:網(wǎng)絡(luò)拍賣4:捐贈(zèng)

  number="1";//購(gòu)買數(shù)量

  transport="3";//1:平郵2:快遞3:虛擬物品

  ordinary_fee="";//平郵運(yùn)費(fèi)

  express_fee="";//快遞運(yùn)費(fèi)

  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(hào)碼

  buyer_mobile="";//買家手機(jī)號(hào)碼

  partner=ConfigurationSettings.AppSettings["partenid"];//合作伙伴ID,這個(gè)是固定的

  上面就是要提供得基本信息,然后就是生成支付寶得連接,也就是給支付寶提供一條帶驗(yàn)證的購(gòu)買信息。

  這個(gè)函數(shù)就是返回生成的地址,里面注釋掉的看你自己需要可以添加進(jìn)去,然后就是md5碼的問(wèn)題,現(xiàn)在用默認(rèn)的md5生成程序?qū)χ形牡闹С种幌抻贕B2312,而支付寶使用的是GBK,雖然兩個(gè)編碼的內(nèi)容GBK兼容GB2312但是畢竟兩個(gè)編碼方式不同,所以會(huì)產(chǎn)生錯(cuò)誤,如果用英文或者數(shù)字不會(huì)有問(wèn)題。上面下載里面帶的一個(gè)md5.asp的算法支持中文。

  現(xiàn)在已經(jīng)可以跳轉(zhuǎn)到支付寶的頁(yè)面了,而我們這邊就要自己記錄用戶的信息已經(jīng)生成的定單編號(hào),這樣在支付寶返回信息的時(shí)候來(lái)查詢。在設(shè)定了返回地址后,我們就要看接收頁(yè)面了。
