+## 介绍
+- 项目介绍说明地址：https://showdoc.axzo.cn/web/#/102?page_id=987
+- 项目接入说明地址：https://showdoc.axzo.cn/web/#/102?page_id=908
+- 项目API说明地址：https://yapi.axzo.cn/project/950/interface/api
+
+## 业务支持场景
+
+### 业务服务新接入进行sql语句配置
+以前端app有文件上传需求，进行接入oss服务进行sql语句配置为例：appCode=app
+```mysql
+INSERT INTO `app_channel_bucket` (`app_channel_bucket_no`, `app_code`, `channel_code`, `bucket_name`, `access_control`, `remark`, `extension`, `create_at`, `update_at`, `create_by`, `update_by`, `is_delete`) VALUES ('app:aliyun:app', 'app', 'aliyun', 'axzo-public', '', NULL, NULL, now(), now(), '', '', 0);
+INSERT INTO `file_app` (`app_code`, `app_name`, `status`, `remark`, `extension`, `create_at`, `update_at`, `create_by`, `update_by`, `is_delete`) VALUES ('app', 'app', 1, 'app', NULL, now(), now(), '', '', 0);
+INSERT INTO `file_business_scene` (`app_channel_bucket_no`, `app_code`, `channel_code`, `bucket_name`, `business_scene`, `directory`, `create_at`, `update_at`, `create_by`, `update_by`, `is_delete`) VALUES ('app:aliyun:app', 'app', 'aliyun', 'axzo-public', 'app', 'app/app', now(), now(), NULL, NULL, 0);
+INSERT INTO `file_upload_config` (`app_channel_bucket_no`, `app_code`, `channel_code`, `bucket_name`, `directory`, `storage_unit`, `storage_size`, `file_format`, `create_at`, `update_at`, `create_by`, `update_by`, `is_delete`) VALUES ('app:aliyun:app', 'app', 'aliyun', 'axzo-public', 'app/app', 'MB', 100, 'png,jpg,xls,xlsx,docx,pdf,zip,dwg,doc,jpeg', now(), now(), NULL, NULL, 0);
+```
+
+### 已接入业务服务支持文件格式配置
+例如appCode=cms，需要支持rar格式文件上传, 支持处理的方式为：
+修改file_upload_config表对字段file_format进行调整，执行以下语句即可：
+```mysql
+update `file_upload_config` SET `file_format` = 'png,jpg,zip,jpeg,pdf,gif,xls,doc,docx,xlsx,bmp,rar' WHERE `app_code` = 'cms'
+```
+
+## 当前提供的能力
+- 文件上传功能
+- 上传功能对接操作日志记录服务。 
+- 对接用户授权获取用户信息。 
+- 根据fileKey获取文件流返回。 
+- 获取文件url兼容处理，传输的为url直接返回。 
+- 支持app端历史数据不存在，进行新增处理。 
+- 获取文件Url支持返回原文件名。 
+- 支持图片处理尺寸样式。 
+- 文件流下载。 
+- 分片上传。
+
+## 未来可扩展
+
+- oss服务业务支持场景手动配置sql语句可切换为管理界面处理，效率提高，可追溯。方案：
+  - oss封装提供给表的curd api接口。
+  - 基础技术管理后台对接调用 oss提供的api接口进行业务接入或者已接入业务服务调整文件格式配置。
+- oss服务重构，简化流程
+  - 多子模块架构，调用链路太长，新功能支持开发较繁琐。
