生成帶參數二維碼的兩種方法
- 需求介紹
- 實現思路
- 方法一：通過微信生成帶參數的二維碼圖片
- 方法二：通過ZXing生成帶參數的二維碼圖片
需求介紹
業務需求，用户微信掃描二維碼進入公眾號中的某一個業務頁面並可以完成相應的業務操作。
例如我的需求就是：用户掃描二維碼進入公眾號的居民滿意度調查頁面，用户在調查頁面進行打分操作。
實現思路
- 生成包含小區ID和需要跳轉的也公眾號授權頁面服務器路徑參數的二維碼圖片；
- 將帶參數的二維碼圖片保存至對應的圖片服務器中。
- 生成對應的小區滿意度調查通知（通知包含公眾號二維碼）。
- 打印通知張貼，掃描通知上的二維碼進入調查打分頁面。
關聯公共號ID,獲取token等基礎操作在此省略，掃描二維碼用户後續操作，不知道的可以查看上一篇微信公共號獲取用户發送信息的前段內容，掃描二維碼動作即是用户掃碼推事件，設置事件類型值為scan。
