json数据格式

{
  "list": [
    {
      "ann_type_name": "邮件", 
      "anne_name": "plugin.png", 
      "anne_path": "/jscdc/upload/eamil/plugin.png", 
      "userid": "11e4-e6a3-4bcea910-a76f-9f966c0d602a"
    }, 
    {
      "ann_type_name": "邮件", 
      "anne_name": "act_6.gif", 
      "anne_path": "/jscdc/upload/eamil/act_6.gif", 
      "userid": "11e4-e6a3-4bcea910-a76f-9f966c0d602a"
