1. 支付寶支付接口(沙箱實(shí)現(xiàn))

1.1 支付寶沙箱賬號(hào)獲取

官網(wǎng)

此處作者已經(jīng)申請(qǐng)了一個(gè)沙箱賬號(hào),申請(qǐng)過(guò)程就不再贅述

如下圖:

2021414114540744

此處可以自行設(shè)置賬戶金額

1.2 下載客戶端(目前好像只支持Android)

2021414114614358

下載完成后根據(jù)官方提供的賬號(hào)以及密碼登錄手機(jī)端支付寶賬號(hào) 如圖(商家賬號(hào)):

其中的參數(shù)獲取如下: app_id

2021414114729081

商戶私鑰,以及支付寶公鑰獲取方法參考官方文檔:密鑰生成

頁(yè)面跳轉(zhuǎn)便是支付以后自動(dòng)跳轉(zhuǎn)的界面

接下來(lái)解釋編寫下單頁(yè)面:
