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(hù)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(xún)。在設(shè)定了返回地址后，我們就要看接收頁(yè)面了。
