订阅步骤

1. 主动拉起订阅，使用接口wx.requestSubscribeSystemMessage(Object object)
2. 如果用户拒绝订阅，下次点击订阅后打开设置页，在设置页回来后通过接口wx.getSetting(Object object)获取用户是否在设置页已经打开了订阅开关

public Subscribe(cb?: Function) {if (!this._sdk) { return; }if (this._Subscribed === 'accept') {Log.log("wx Subscribe 已订阅:", this._Subscribed);cb && cb(1);return;}let request = () => {this._sdk!.requestSubscribeSystemMessage({msgTypeList: ['SYS_MSG_TYPE_WHATS_NEW'],success: (res:any) => {this._Subscribed = res['SYS_MSG_TYPE_WHATS_NEW'];if (this._Subscribed === 'accept') {Log.log("wx Subscribe 订阅成功:", this._Subscribed);cb && cb(0);} else {Log.log("wx Subscribe 订阅失败:", this._Subscribed);cb && cb(-1);}},fail: (res) => {Log.log("wx Subscribe 订阅失败:", res);cb && cb(-1);}})}let openSetting = () => {this._sdk!.openSetting({withSubscriptions: true,success:()=>{this._waitSubscribe = true;},fail: (res) => {cb && cb(-1);},});}if (!this._Subscribed || this._Subscribed.length == 0) {request();} else {openSetting();}
}public onShow(callback?: Function) {if (!this._sdk) {return;}this._sdk!.onShow((res: WechatMinigame.OnShowListenerResult) => {if (this._waitSubscribe) {this._waitSubscribe = false;this.checkSubscribe(true);}});
}
private checkSubscribe(bNeedEvent : boolean) {if (!this._sdk) {return;}if (this._Subscribed === 'accept') {return;}this._sdk.getSetting({withSubscriptions: true,success: (res) => {if (res.subscriptionsSetting && res.subscriptionsSetting.itemSettings && res.subscriptionsSetting.itemSettings.SYS_MSG_TYPE_WHATS_NEW) {this._Subscribed = res.subscriptionsSetting.itemSettings.SYS_MSG_TYPE_WHATS_NEW;Log.log("wx Subscribe 订阅状态:", this._Subscribed);if (bNeedEvent && this._Subscribed === 'accept') {//TO DO SOMTHING}}},fail: (res) => {Log.log("wx getSetting fail:", res);}});
}
