此篇針對(duì) iOS 支付進(jìn)行一次小結(jié),很久沒(méi)碰這塊了,有些方法 Apple 官方也進(jìn)行了優(yōu)化,故也將隨之進(jìn)行更新.

首先,code 部分將分為兩部分,一部分在 appdelegate 中,另一部分單獨(dú)封裝在了一個(gè)類(lèi)中執(zhí)行,需要使用的地方調(diào)用的接口方法.

其次,大體支付流程為獲取到充值價(jià)格訂單列表后,選擇對(duì)應(yīng)的價(jià)格后向 Apple 發(fā)起支付請(qǐng)求,接收到 Apple 支付回調(diào)后,根據(jù)結(jié)果處理相關(guān)邏輯,最后將處理完成的結(jié)果反饋至用戶(hù).

其過(guò)程中會(huì)分為幾個(gè)環(huán)節(jié)來(lái)處理:

若支付失敗則執(zhí)行異常處理并將最后處理結(jié)果信息反饋至用戶(hù);

若支付成功則對(duì)支付憑證校驗(yàn),此篇文章中的校驗(yàn)過(guò)程分為兩部分,先是由客戶(hù)端自行校驗(yàn),若校驗(yàn)成功則將相關(guān)用戶(hù)信息和支付憑證發(fā)送至服務(wù)端進(jìn)行二次校驗(yàn);

其中,客戶(hù)端優(yōu)先進(jìn)行交易憑證校驗(yàn),校驗(yàn)失敗則將校驗(yàn)的異常處理信息反饋至用戶(hù);反之,校驗(yàn)成功則再次將相關(guān)用戶(hù)信息和本次支付憑證數(shù)據(jù)一并發(fā)送至服務(wù)端進(jìn)行二次校驗(yàn),最終將雙重驗(yàn)證后的結(jié)果信息反饋至用戶(hù),從而為了避免刷單的情況.

最后,文章中具體處理邏輯中可能會(huì)因?yàn)樾枨蟮牟煌c實(shí)際有些小的出入,但大體流程應(yīng)該是一致的,也會(huì)對(duì)應(yīng)添加相應(yīng)的注釋,若存在不清楚的地方可以帖子下方留言溝通交流.

大致支付流程:

1.蘋(píng)果APP(商家)

2.告訴蘋(píng)果Store服務(wù)器要賣(mài)的商品

3.蘋(píng)果審核完(告訴你是否可以賣(mài))

4.用戶(hù)(買(mǎi)商品)

5.蘋(píng)果APP(商家)

6.開(kāi)發(fā)票給(用戶(hù))

7.用戶(hù)(拿著發(fā)票去蘋(píng)果Store服務(wù)器付款)

8.付款成功(用戶(hù)在APP里獲得服務(wù)商品)

注:如果要模擬測(cè)試內(nèi)購(gòu),需要用真機(jī)才可以測(cè)試
