WeChat program API subscribes to messages

wx.requestSubscribeMessage(Object object)

Base Library 2.4.4 starts to support, and low versions need to be compatible.

Call up the client program subscription message interface and return the results of the user's subscription message. When the user ticks "Always keep the above selection, don't ask again" in the subscription panel, the template message is added to the user's small program settings page, and the user's subscription status to the relevant template message is obtained through the wx.getSetting interface.

The one-time template id and the permanent template id cannot be used at the same time.
The low-version base library 2.4.4 to 2.8.3 already supports subscription message interface calls and only one-time tmplId / permanent tmplId.
2.8.2 The subscription message interface can only be recalled after the user has clicked or initiated a payment callback since the release began.
Starting with version 2.10.0, the development and experience applets will prohibit the use of the template message formId.
