对照了appid,原始id都没错，但就是拉不起小程序
        String appId = "wxad6628d95702e398"; // 填应用AppId
            IWXAPI api = WXAPIFactory.createWXAPI(getActivity(), appId)
//            api.registerApp(appId);

            WXLaunchMiniProgram.Req req = new WXLaunchMiniProgram.Req()
            req.userName = "gh_8bf4b612c524"; // 填小程序原始id
            ///pages/newIndex/newIndex?productId=11&pay4id=5922561&index=0
            req.path = "/pages/newIndex/newIndex?productId=" + mSelectChargeBeanchargeProdId + "&pay4id=" + pay4id + "&index=" + index;                  //拉起小程序页面的可带参路径，不填默认拉起小程序首页
            req.miniprogramType = WXLaunchMiniProgram.Req.MINIPTOGRAM_TYPE_RELEASE// 可选打开 开发版，体验版和正式版
            Log."miniPrograme", req.path
            api.sendReq(req)
