                $token = $auth->uploadToken($bucket);
                // 初始化 UploadManager 对象并进行文件的上传
                $uploadMgr = new UploadManager();
                // 调用 UploadManager 的 putFile 方法进行文件的上传
                list($ret, $err) = $uploadMgr->putFile($token, $key, $filePath);
                if ($err !== null) {
                    return ["err"=>1,"msg"=>$err,"data"=>""];
                } else {
                    //返回图片的完整URL
                    $imgPath=$domain.'/'.$key;
                    //赋值
                    $data["thumb_url"] = $imgPath;
                    $data = Db::name('top_bar')->insert($data);
                    $this->redirect("/admin/topbar/index");
