背景
最近公司項目一直在圍繞著支付寶做應用開發(fā),為了能保證消息能夠及時的給用戶傳遞,因此需要開發(fā)模板消息的功能,而小程序的模板消息也是最快捷的通知方式
事先準備1、請仔細閱讀支付寶模板消息發(fā)送指引:模板消息指引
2、仔細閱讀用戶的授權文檔,用戶授權的詳細的實現(xiàn)步驟可以見我寫的另外一篇文章:《PHP實現(xiàn)支付寶小程序用戶授權的工具類》
3、在小程序中加入模板消息的權限,如下圖
4、仔細閱讀支付寶發(fā)送模板消息接口文檔:alipay.open.app.mini.templatemessage.send
5、事先通過小程序的form組件收集好對一個的formid,formid組件文檔
6、將小程序綁定到生活號上
7、配置一個模板消息編號,詳細步驟:小程序--->模板消息,最終配置號的模板消息如下
1、通過客戶端的form組件,收集好formid,并多帶帶開一個后端接口將formid通過http請求保存到后臺,最好是盡可能多的收集formid,比如按鈕的點擊事件、tab的切換上都可以增加formid組件
2、通過調用alipay.open.app.mini.templatemessage.send接口,給客戶端發(fā)送模板消息 ,注意支付寶所有的模板消息都是基于生活號進行分發(fā)的,所以事先一定要綁定好對應的生活號
