微信小程序订阅消息

前端弹窗获取订阅消息授权

let tmplIds="" ; //消息模板id
wx.getSetting({
      withSubscriptions: true,   //  这里设置为true,下面才会返回mainSwitch
      success: function(res){   
      
        // 调起授权界面弹窗
        if (res.subscriptionsSetting.mainSwitch) {  // 用户打开了订阅消息总开关
          if (res.subscriptionsSetting.itemSettings != null) {   // 用户同意总是保持是否推送消息的选择, 这里表示以后不会再拉起推送消息的授权
            let moIdState = res.subscriptionsSetting.itemSettings[tmplIds];  // 用户同意的消息模板id
            if(moIdState === 'accept'){   
              console.log('接受了消息推送');

            }else if(moIdState === 'reject'){
              console.log("拒绝消息推送");

            }else if(moIdState === 'ban'){
              console.log("已被后台封禁");

            }
          }else {
          	// 当用户没有点击 ’总是保持以上选择，不再询问‘  按钮。那每次执到这都会拉起授权弹窗
            wx.showModal({
              title: '提示',
              content:'请授权开通服务通知',
              showCancel: true,
              success: function (ress) {
                if (ress.confirm) {  
                  wx.requestSubscribeMessage({   // 调起消息订阅界面
                    tmplIds: [tmplIds],
                    success (res) { 
                      console.log('订阅消息 成功 ');
