关于获取access_token、同步菜单以及创建自定义菜单

1.首先我们要有appid（wx4ff531ee8a470861）和appsecret（2ec9b2f1a1f67b8743d23f9fc70c1c97）。

2.这里我们用的是rh_mp与rh_mp_menu数据表。

3.首先我们在Common模块的Common文件夹下创建function.php文件，在里面我们写入以下获取access_token的代码和获取当前公众号的代码：

function getAccess_token(){
	$mp=M('mp')->where('is_use=1')->find();
	if(empty($mp)) return false;
	$id=$mp['id'];
	  if(empty($mp['access_token']) || $mp['expire_time']where("id=$id")->save($data);
        
        	return $arr['access_token'];
        }else{
        	return false;
        }
	  }else{
	  	return $mp['access_token'];
	  }

function getCurrentMp(){
	$mp=M('mp')->where('is_use=1')->find();
	return  $mp;
}

在menuController.class.php中增加以下代码：

error('无此公账号',U('mp/index'));
		}
		$data=M('mp_menu')->where("mp_id={$mp['id']}")->order('id')->select();
		$data2=$data;
		foreach ($data as $k => $v) {
			foreach ($data2 as $k2 => $v2) {
				if($v['index']==$v2['pindex']){
					$data[$k]['sub'][]=$v2;
					unset($data[$k2]);
				}
			}
		}

		$this->assign('mpInfo',$mp);
		$this->assign('list',$data);
		$this->display();
	}
	public function menuedit(){
		$mp=getCurrentMp();
		if(empty($mp)){
			$this->ajaxReturn(array('error'=>true,'msg'=>'无此公账号','url'=>U('mp/index')));
			exit;
		}
		$data=I('post.data');

		foreach ($data as  &$value) {
			$value['mp_id']=$mp['id'];
		}
		// }print_r($value);
		// exit;
		// $this->ajaxReturn($data);
		// $arr=array();
		// foreach ($data1 as $key => $value) {
		// 	$row=array();
		// 	$row['mp_id']=$mp['id'];
		// 	$row['index']=$value['id'];
		// 	$row['pindex']=$value['pid'];
		// 	$row['name']=$value['name'];
		// 	$row['content']=$value['code'];
		// 	$row['type']=$value['type'];
		// 	$row['sort']=$value['sort'];
		// 	$arr[]=$row;
		// }
		$model=M('mp_menu');
		$model->where("mp_id={$mp['id']}")->delete();
		$model->addAll($data);
		// $this->ajaxReturn(array('error'=>false,'data'=>$arr));
		// exit;
		// $data2=$data1;
		// foreach ($data1 as $key1 => $value1) {
		// 	foreach ($data2 as $key2 => $value2) {
		// 		if($value1['id']==$value2['pid']){
		// 			$data1[$key1]['type']='';
		// 			$data1[$key1]['code']='';
		// 			break;
		// 		}
		// 	}
		// 	unset($data1[$key1]['sort']);
		// 	if($value['type']='event'){
		// 		$value['type']=$value['code'];
		// 		$value['code']='k_'.rand(100,999);
		// 	}
		// }

最后在页面上创建菜单显示如下图：

这样说明创建菜单成功！

然后我们把数据库清空。

然后我们刷新页面：

当我们点击同步菜单后出现：

这样说明我们已经把服务器的菜单获取到了，并且已经写入数据库了。
