java订阅_微信⼩程序订阅消息（java后端实现）开发订阅消息说明订阅消息是微信近期新出的⼀个能⼒,⽤来代替原有的模板消息(原有的模板消息即将下线)订阅消息的功能较模板消息有所提升,"7天"的限制取消,同时有"⼀次性"和"永久"订阅.(功能上是这样说的,但是实际开发时发现"永久"订阅还是对⼩程序的服务类⽬有要求的,客户的⼩程序只⽀持"⼀次性"订阅)官⽅通道:⼩程序前端:点击进⼊⼩程序服务端:点击进⼊开发思路⽤户在⼩程序内触发按钮或进⾏⽀付操作时前端调⽤订阅消息授权框,默认⼀次授权只能发送⼀次订阅消息如果⽤户勾选"下次⾃动授权",下次将不再弹出授权框->点击按钮直接拥有⼀次发送订阅消息的机会,此处不需要模板消息的"formId",较之前更简单经过测试,如果在⼩程序上多次点击触发授权的按钮,发送订阅消息的机会可以累加!!!(如,1分钟内点击了10次按钮,后⾯将拥有10次发送订阅消息的机会,什么时候发都可以)代码实现(仅java后端)实体类部分blic
