Laravel 框架返回状态拦截代码

可拦截系统的返回的状态自己在单独处理。

使用查询

composer require betterde/response
// 安装后直接调用以下
# stored
return stored($data, $message = '创建成功');
 
#updated
return updated($data, $message = '更新成功');
 
#deleted
return deleted($message = '删除成功');
 
#accepted
return accepted($message = '请求已接受，等待处理');
 
#notFound
return notFound($message = '您访问的资源不存在');
 
#internalError
return internalError($message = '未知错误导致请求失败');
 
#failed
return failed($message, $code = Response::HTTP_BAD_REQUEST);
 
#success
return success($data);
 
#message
return message($message, $code = Response::HTTP_OK);
 
#respond
return respond($data = [], $message = '请求成功', array $header = []);
