【移動(dòng)應(yīng)用開發(fā)技術(shù)】微信開發(fā)之現(xiàn)金紅包接口如何實(shí)現(xiàn)紅包發(fā)放功能

這篇文章給大家分享的是有關(guān)微信開發(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。在下覺得挺實(shí)用的，因此分享給大家做個(gè)參考，一起跟隨在下過(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：微信用戶訪問紅包活動(dòng)頁(yè)面--》后端判斷是否是微信訪問的【否：提示用微信打開連接，是：提示用戶是否授權(quán)允許，獲取其的用戶信息【openID等信息】】--》進(jìn)入紅包活動(dòng)頁(yè)面》用戶點(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--》微信用戶在微信中收到紅包--》打開紅包--》紅包金額會(huì)添加到錢包零錢里--》完成紅包發(fā)放?！慷阂獙?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-開發(fā)者中心頁(yè)，點(diǎn)擊“修改配置”按鈕，填寫服務(wù)器地址（URL）、Token和EncodingAESKey，其中URL是開發(fā)者用來(lái)接收微信消息和事件的接口URL。Token可由開發(fā)者可以任意填寫，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由開發(fā)者手動(dòng)填寫或隨機(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?！続ppID和AppSecret可在微信公眾平臺(tái)官網(wǎng)-開發(fā)者中心頁(yè)中獲得（需要已經(jīng)成為開發(fā)者，且?guī)ぬ?hào)沒有異常狀態(tài)）?！?.微信公眾號(hào)要開通“網(wǎng)頁(yè)授權(quán)接口”用戶獲取用戶基本信息【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

”商戶號(hào)”要開通微信支付【發(fā)紅包的金額是該支付賬戶扣款】，開通“現(xiàn)金紅包”接口【調(diào)用該接口發(fā)放紅包】。6.登陸”商戶號(hào)”【微信公眾號(hào)分配的商戶號(hào)。第5中有說(shuō)明】在“API安全”中下載PHP版的證書【.pem格式】以上如描述不清楚，請(qǐng)查看微信開發(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】：<?php
