 final IWXAPI api = WXAPIFactory.createWXAPI(SettingActivity.this, response.getAppId());                // 將該app註冊到                api.registerApp(ServerUrls.WEIXIN_APP_ID);                Log.i("20180228", "come to send request with subscribeMessage....");                SubscribeMessage.Req req = new SubscribeMessage.Req();                req.templateID = response.getTemplateId();                req.scene = 889;//                req.reserved = response.getReserved();                Log.i("20180228", "req.appId: "+response.getAppId());                Log.i("20180228", "req.templateId: "+req.templateID);//                Log.i("20180228", "req.scene: "+req.scene);//                Log.i("20180228", "req.reserved: "+req.reserved);                Log.i("20180228", "before send request: "+req.toString());                boolean sendResult = api.sendReq(req);                Log.i("20180228", "after send request: "+sendResult);                ToastUtils.show(SettingActivity.this, "發送請求結束");

在授權頁面的回調中做簡單的處理：

@Override    public void onResp(BaseResp resp) {        Log.i("20180228", "here come to the resp with wechat request: "+resp.toString());        Log.i("20180228", "here come to the resp with wechat errCode: "+resp.errCode);        Log.i("20180228", "here come to the resp with wechat errStr: "+resp.errStr);        Log.i("20180228", "here come to the resp with wechat openId: "+resp.openId);        Log.i("20180228", "here come to the resp with wechat type: "+resp.getType());        ToastUtils.show(this, "openId: "+resp.openId);        if(resp.getType() == ConstantsAPI.COMMAND_SUBSCRIBE_MESSAGE){            Log.i("20180305", "here come to resp method successful....");        }//        if (resp.getType() == ConstantsAPI.COMMAND_SENDAUTH && resp.errCode == BaseResp.ErrCode.ERR_OK){//            ToastUtils.show(this, "request auth here ....");//            String openId = resp.openId;//            int errCode = resp.errCode;//            String errString = resp.errStr;////            new UserManager(this).bidnWXRSS(openId, new SimpleCallback<ApiResponse>() {//                @Override//                public void onSuccess(ApiResponse response) {//                    ToastUtils.show(WXEntryActivity.this, "綁定成功!");//                    finish();//                }//            });//        }        finish();    }

在開啟的調試列印中顯示：

handleIntent()的時候，返回的是false，也沒法調用onResp方法，其中的原因是因為上面的respType = null，但是上面發現extInfo是有資料的，並且可以看出wx_internal_resptype=subscribemessage。

這邊查看WXApiImplV10.class，部分代碼如下：

也就是說，這邊的respType=subscribemessage，但是上面解析出來變成了null， 其中關鍵的代碼是：

然後才明白，這邊的extInfo字串的起始處少了一個“?”，所以把extInfo解析成Uri後，就找不到指定的“wx_internal_resptype”屬性了。所以頁面會卡在WXEntryActivity頁面沒有進行下一步的操作，這邊希望Team Dev可以儘早處理！
