掃二維碼關注服務號同時發現金紅包

本文只是記錄一下本身最近開發的一個小功能，方便之後查看。

1、需求原文以下：

1.vip微信參數配置

   1)是否啓用

   2)設置每單最大紅包金額    (例如5 )

   3)設置各種別 紅包金額範圍  

                     鑽石    3-5

                     黃金    2-3  等等

2.質量保證單 

   打印二維碼 參數傳銷售門店 以及銷售單號

   客戶掃碼 

          1)自動關注服務號

          2)自動匹配客戶檔案

             openid 匹配到檔案的增長積分以及總積分 ，

             未匹配到檔案的  客戶填寫  姓名,手機號 若是手機號匹配到記錄  自動將客戶檔案關聯上

             手機號也未匹配到記錄  自動創建檔案（自動插入所屬分銷商id,微信openid,姓名,手機號,總積分，剩餘積分  必填項添默認值）

                                             

             

          3)根據用戶結果 自動關聯客戶消費記錄

          4)根據積分規則判斷消費完客戶是否達成升級標準（客戶等級只升不降）

          5)根據參數配置   自動發送一個紅包給客戶   同單屢次掃描只發送一次紅包.

                   紅包規則  1.判斷是否啓用     沒有啓用不發送

                                   2.發送紅包時 取明細條碼裏面 紅包金額上限最大的 記錄  隨機生成一個金額的紅包發送

                                   例如  客戶購買2件貨品   鑽石   3-5   黃金2-3

                                         那麼隨機發送一個 3-5元的紅包給客戶

                                       （暫不考慮銷退的狀況）

 

 2、需求理解：簡單來講就是門店下單時須要在質保單上面打印上咱們的服務號二維碼（二維碼參數帶上訂單號），掃碼時根據openid（客戶微信號在咱們的服務號惟一的標示）匹配客戶表，若是以前已經存在，就根據單號和積分規則計算客戶的積分，沒發過紅包的單就發送一個根據類別配置金額的紅包給客戶。若是openid沒有匹配到就給個連接填寫vip信息，以後發送紅包和消費記錄，同時計算積分。

 

3、實操

1.服務號申請 2.開通支付功能，下載證書。  3.調用帶參數的二維碼接口生成二維碼。4.響應關注事件（判斷用戶身份，計算積分，發送紅包等）

微信服務號幫助類

 

微信紅包功能能夠參考：csdn的實例下載。

 

4、效果

 

4、開發總結

1.這個功能應該是鏈接客戶比較實用的功能，提升客戶的依賴度。

2.開發時調試比較麻煩，個人方法是使用微信服務號的api發送錯誤日誌到個人微信上，另外一個方法是本身模擬微信的回調事件（這個方法很好，能夠直接在vs中調試）。
