微信現金紅包接口實現紅包發放：

一：流程：【

流程：微信用戶訪問紅包活動頁面--》后端判斷是否是微信訪問的

【否：提示用微信打開連接，是：提示用戶是否授權允許，獲取其的用戶信息【openID等信息】】--》

進入紅包活動頁面---》用戶點擊領取紅包【判斷是否領取過紅包】是：【提示已領取過紅包】否?

--》后端程序調用接口發放紅包

--》微信用戶在微信中收到紅包

--》打開紅包

--》紅包金額會添加到錢包零錢里

--》完成紅包發放。

】

二：要實現微信現金紅包接口實現紅包發放，首先要符合以下條件：

1.用于發放紅包的微信公眾號要是服務類型

2.登錄微信公眾平臺官網后，在公眾平臺后臺管理頁面 - 開發者中心頁，

點擊“修改配置”按鈕，填寫服務器地址（URL）、Token和EncodingAESKey，

其中URL是開發者用來接收微信消息和事件的接口URL。Token可由開發者可以任意填寫，

用作生成簽名（該Token會和接口URL中包含的Token進行比對，從而驗證安全性）。

EncodingAESKey由開發者手動填寫或隨機生成，將用作消息體加解密密鑰。

3.獲取access_token：公眾號可以使用AppID和AppSecret調用本接口來獲取access_token。

【AppID和AppSecret可在微信公眾平臺官網-開發者中心頁中獲得（需要已經成為開發者，且帳號沒有異常狀態）。】

4.微信公眾號要開通 “網頁授權接口” 用戶獲取用戶基本信息【特別是openID ，發紅包時用到】

5.微信公眾號的 “微信支付“ ?中的 ?”商戶號” 要開通微信支付【發紅包的金額是該支付賬戶扣款】，開通“現金紅包”接口【調用該接口發放紅包】。

6. 登陸 ”商戶號”【微信公眾號分配的商戶號。第5 中有說明】 在 “API安全” 中 下載PHP版的 證書 【.pem格式】

以上如描述不清楚，請查看 微信開發者文檔 里面有詳細的秒殺。

部分代碼如下【其余的請查看附件】：
