微信一次性订阅消息接入问题解析

本文主要和大家分享微信一次性订阅消息接入问题解析，环境都已经接入，发送 一次性订阅消息 授权：

 final IWXAPI api = WXAPIFactory.createWXAPI(SettingActivity.this, response.getAppId());                // 将该app注册到微信                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, "发送请求结束");

在授权页面的回调中做简单的处理：

@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, "绑定成功!");//                    finish();//                }//            });//        }        finish();    }

在打开的调试打印中显示：

handleIntent()的时候，返回的是false，也没法调用onResp方法，其中的原因是因为上面的respType = null，但是上面发现extInfo是有数据的，并且可以看出wx_internal_resptype=subscribemessage。

这边查看WXApiImplV10.class，部分代码如下：

也就是说，这边的respType=subscribemessage，但是上面解析出来变成了null， 其中关键的代码是：

然后才明白，这边的extInfo字符串的起始处少了一个“?”，所以把extInfo解析成Uri后，就找不到指定的“wx_internal_resptype”属性了。所以页面会卡在WXEntryActivity页面没有进行下一步的操作，这边希望微信开发团队可以尽早处理！
