這篇文章給大家分享的是有關(guān) 微信開(kāi)發(fā)之現(xiàn)金紅包接口如何實(shí)現(xiàn)紅包發(fā)放功能的內(nèi)容。小編覺(jué)得挺實(shí)用的,因此分享給大家做個(gè)參考,一起跟隨小編過(guò)來(lái)看看吧。
微信現(xiàn)金紅包接口實(shí)現(xiàn)紅包發(fā)放:
一:流程:【
流程:微信用戶(hù)訪問(wèn)紅包活動(dòng)頁(yè)面--》后端判斷是否是微信訪問(wèn)的
【否:提示用微信打開(kāi)連接,是:提示用戶(hù)是否授權(quán)允許,獲取其的用戶(hù)信息【openID等信息】】--》
進(jìn)入紅包活動(dòng)頁(yè)面---》用戶(hù)點(diǎn)擊領(lǐng)取紅包【判斷是否領(lǐng)取過(guò)紅包】是:【提示已領(lǐng)取過(guò)紅包】否
--》后端程序調(diào)用接口發(fā)放紅包
--》微信用戶(hù)在微信中收到紅包
--》打開(kāi)紅包
--》紅包金額會(huì)添加到錢(qián)包零錢(qián)里
--》完成紅包發(fā)放。
】
二:要實(shí)現(xiàn)微信現(xiàn)金紅包接口實(shí)現(xiàn)紅包發(fā)放,首先要符合以下條件:
1.用于發(fā)放紅包的微信公眾號(hào)要是服務(wù)類(lèi)型
2.登錄微信公眾平臺(tái)官網(wǎng)后,在公眾平臺(tái)后臺(tái)管理頁(yè)面 - 開(kāi)發(fā)者中心頁(yè),
點(diǎn)擊“修改配置”按鈕,填寫(xiě)服務(wù)器地址(URL)、Token和EncodingAESKey,
其中URL是開(kāi)發(fā)者用來(lái)接收微信消息和事件的接口URL。Token可由開(kāi)發(fā)者可以任意填寫(xiě),
用作生成簽名(該Token會(huì)和接口URL中包含的Token進(jìn)行比對(duì),從而驗(yàn)證安全性)。
EncodingAESKey由開(kāi)發(fā)者手動(dòng)填寫(xiě)或隨機(jī)生成,將用作消息體加解密密鑰。
3.獲取access_token:公眾號(hào)可以使用AppID和AppSecret調(diào)用本接口來(lái)獲取access_token。
【AppID和AppSecret可在微信公眾平臺(tái)官網(wǎng)-開(kāi)發(fā)者中心頁(yè)中獲得(需要已經(jīng)成為開(kāi)發(fā)者,且?guī)ぬ?hào)沒(méi)有異常狀態(tài))。】
4.微信公眾號(hào)要開(kāi)通 “網(wǎng)頁(yè)授權(quán)接口” 用戶(hù)獲取用戶(hù)基本信息【特別是openID ,發(fā)紅包時(shí)用到】
5.微信公眾號(hào)的 “微信支付“ 中的 ”商戶(hù)號(hào)” 要開(kāi)通微信支付【發(fā)紅包的金額是該支付賬戶(hù)扣款】,開(kāi)通“現(xiàn)金紅包”接口【調(diào)用該接口發(fā)放紅包】。
6. 登陸 ”商戶(hù)號(hào)”【微信公眾號(hào)分配的商戶(hù)號(hào)。第5 中有說(shuō)明】 在 “API安全” 中 下載PHP版的 證書(shū) 【.pem格式】
以上如描述不清楚,請(qǐng)查看 微信開(kāi)發(fā)者文檔 里面有詳細(xì)的秒殺。
部分代碼如下【其余的請(qǐng)查看附件】:
