[LayaAir3]使用3.2.2打包成apk post请求发送不出去换成3.2.1打包成apk post请求就能正常发送

您好，方便发一个demo吗

if (this._httpRequest == null) {
            this._httpRequest = new Laya.HttpRequest();
            this._httpRequest.on(Laya.Event.COMPLETE, this, this.onPostComplete);
            this._httpRequest.on(Laya.Event.ERROR, this, this.onPostIOError);
            this._httpRequest.on(Laya.Event.PROGRESS, this, this.onPostProgress);
        }
   
       sb是ArrayBuffer
this._httpRequest.send(GameGlobal.serverUrl + "/req", sb, 'post', "arraybuffer", ["Content-Type", "application/octet-stream"]);
