           TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
        
           1. Definitions.
        
              "License" shall mean the terms and conditions for use, reproduction,
              and distribution as defined by Sections 1 through 9 of this document.
        
              "Licensor" shall mean the copyright owner or entity authorized by
              the copyright owner that is granting the License.
        
              "Legal Entity" shall mean the union of the acting entity and all
              other entities that control, are controlled by, or are under common
              control with that entity. For the purposes of this definition,
              "control" means (i) the power, direct or indirect, to cause the
              direction or management of such entity, whether by contract or
              otherwise, or (ii) ownership of fifty percent (50%) or more of the
              outstanding shares, or (iii) beneficial ownership of such entity.
        
              "You" (or "Your") shall mean an individual or Legal Entity
              exercising permissions granted by this License.
        
              "Source" form shall mean the preferred form for making modifications,
              including but not limited to software source code, documentation
              source, and configuration files.
        
              "Object" form shall mean any form resulting from mechanical
              transformation or translation of a Source form, including but
              not limited to compiled object code, generated documentation,
              and conversions to other media types.
        
              "Work" shall mean the work of authorship, whether in Source or
              Object form, made available under the License, as indicated by a
              copyright notice that is included in or attached to the work
              (an example is provided in the Appendix below).
        
              "Derivative Works" shall mean any work, whether in Source or Object
              form, that is based on (or derived from) the Work and for which the
              editorial revisions, annotations, elaborations, or other modifications
              represent, as a whole, an original work of authorship. For the purposes
              of this License, Derivative Works shall not include works that remain
              separable from, or merely link (or bind by name) to the interfaces of,
              the Work and Derivative Works thereof.
        
              "Contribution" shall mean any work of authorship, including
              the original version of the Work and any modifications or additions
              to that Work or Derivative Works thereof, that is intentionally
              submitted to Licensor for inclusion in the Work by the copyright owner
              or by an individual or Legal Entity authorized to submit on behalf of
              the copyright owner. For the purposes of this definition, "submitted"
              means any form of electronic, verbal, or written communication sent
              to the Licensor or its representatives, including but not limited to
              communication on electronic mailing lists, source code control systems,
              and issue tracking systems that are managed by, or on behalf of, the
              Licensor for the purpose of discussing and improving the Work, but
              excluding communication that is conspicuously marked or otherwise
              designated in writing by the copyright owner as "Not a Contribution."
        
              "Contributor" shall mean Licensor and any individual or Legal Entity
              on behalf of whom a Contribution has been received by Licensor and
              subsequently incorporated within the Work.
        
           2. Grant of Copyright License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              copyright license to reproduce, prepare Derivative Works of,
              publicly display, publicly perform, sublicense, and distribute the
              Work and such Derivative Works in Source or Object form.
        
           3. Grant of Patent License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              (except as stated in this section) patent license to make, have made,
              use, offer to sell, sell, import, and otherwise transfer the Work,
              where such license applies only to those patent claims licensable
              by such Contributor that are necessarily infringed by their
              Contribution(s) alone or by combination of their Contribution(s)
              with the Work to which such Contribution(s) was submitted. If You
              institute patent litigation against any entity (including a
              cross-claim or counterclaim in a lawsuit) alleging that the Work
              or a Contribution incorporated within the Work constitutes direct
              or contributory patent infringement, then any patent licenses
              granted to You under this License for that Work shall terminate
              as of the date such litigation is filed.
        
           4. Redistribution. You may reproduce and distribute copies of the
              Work or Derivative Works thereof in any medium, with or without
              modifications, and in Source or Object form, provided that You
              meet the following conditions:
        
              (a) You must give any other recipients of the Work or
                  Derivative Works a copy of this License; and
        
              (b) You must cause any modified files to carry prominent notices
                  stating that You changed the files; and
        
              (c) You must retain, in the Source form of any Derivative Works
                  that You distribute, all copyright, patent, trademark, and
                  attribution notices from the Source form of the Work,
                  excluding those notices that do not pertain to any part of
                  the Derivative Works; and
        
              (d) If the Work includes a "NOTICE" text file as part of its
                  distribution, then any Derivative Works that You distribute must
                  include a readable copy of the attribution notices contained
                  within such NOTICE file, excluding those notices that do not
                  pertain to any part of the Derivative Works, in at least one
                  of the following places: within a NOTICE text file distributed
                  as part of the Derivative Works; within the Source form or
                  documentation, if provided along with the Derivative Works; or,
                  within a display generated by the Derivative Works, if and
                  wherever such third-party notices normally appear. The contents
                  of the NOTICE file are for informational purposes only and
                  do not modify the License. You may add Your own attribution
                  notices within Derivative Works that You distribute, alongside
                  or as an addendum to the NOTICE text from the Work, provided
                  that such additional attribution notices cannot be construed
                  as modifying the License.
        
              You may add Your own copyright statement to Your modifications and
              may provide additional or different license terms and conditions
              for use, reproduction, or distribution of Your modifications, or
              for any such Derivative Works as a whole, provided Your use,
              reproduction, and distribution of the Work otherwise complies with
              the conditions stated in this License.
        
           5. Submission of Contributions. Unless You explicitly state otherwise,
              any Contribution intentionally submitted for inclusion in the Work
              by You to the Licensor shall be under the terms and conditions of
              this License, without any additional terms or conditions.
              Notwithstanding the above, nothing herein shall supersede or modify
              the terms of any separate license agreement you may have executed
              with Licensor regarding such Contributions.
        
           6. Trademarks. This License does not grant permission to use the trade
              names, trademarks, service marks, or product names of the Licensor,
              except as required for reasonable and customary use in describing the
              origin of the Work and reproducing the content of the NOTICE file.
        
           7. Disclaimer of Warranty. Unless required by applicable law or
              agreed to in writing, Licensor provides the Work (and each
              Contributor provides its Contributions) on an "AS IS" BASIS,
              WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
              implied, including, without limitation, any warranties or conditions
              of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
              PARTICULAR PURPOSE. You are solely responsible for determining the
              appropriateness of using or redistributing the Work and assume any
              risks associated with Your exercise of permissions under this License.
        
           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or consequential damages of any character arising as a
              result of this License or out of the use or inability to use the
              Work (including but not limited to damages for loss of goodwill,
              work stoppage, computer failure or malfunction, or any and all
              other commercial damages or losses), even if such Contributor
              has been advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,
              and charge a fee for, acceptance of support, warranty, indemnity,
              or other liability obligations and/or rights consistent with this
              License. However, in accepting such obligations, You may act only
              on Your own behalf and on Your sole responsibility, not on behalf
              of any other Contributor, and only if You agree to indemnify,
              defend, and hold each Contributor harmless for any liability
              incurred by, or claims asserted against, such Contributor by reason
              of your accepting any such warranty or additional liability.
        
           END OF TERMS AND CONDITIONS
        
           APPENDIX: How to apply the Apache License to your work.
        
              To apply the Apache License to your work, attach the following
              boilerplate notice, with the fields enclosed by brackets "[]"
              replaced with your own identifying information. (Don't include
              the brackets!)  The text should be enclosed in the appropriate
              comment syntax for the file format. We also recommend that a
              file or class name and description of purpose be included on the
              same "printed page" as the copyright notice for easier
              identification within third-party archives.

# FiuAI S3

一个支持阿里云OSS和MinIO的对象存储抽象包，提供了统一的接口来操作不同的对象存储服务。

## 特性

- 支持阿里云OSS和MinIO存储服务
- 统一的接口设计
- 工厂模式实现，易于扩展
- 完整的类型提示
- 详细的日志记录
- 异常处理机制

## 安装

```bash
pip install fiuai-s3
```

## 快速开始

### 初始化存储

```python
# file: utils/s3.py
from fiuai_s3 import ObjectStorageFactory
from config.app_config import get_settings

ObjectStorageFactory.initialize(
        # 初始化对象存储
        provider=get_settings().object_storage_config.provider,
        bucket_name=get_settings().object_storage_config.bucket_name,
        endpoint=get_settings().object_storage_config.endpoint,
        access_key=get_settings().object_storage_config.access_key,
        secret_key=get_settings().object_storage_config.secret_key,
        temp_dir=get_settings().object_storage_config.s3_temp_dir,
        use_https=get_settings().object_storage_config.s3_use_https
    
)
S3_Client = ObjectStorageFactory.get_instance()

```


### 使用存储实例

```python
# file: app.py
from utils.s3 import S3_Client

# 上传文件
S3_Client.upload_file("test.txt", b"Hello World")

# 下载文件
data = S3_Client.download_file("test.txt")

# 删除文件
S3_Client.delete_file("test.txt")

# 列出文件
files = S3_Client.list_files(prefix="test/")
```

### 单据文件管理（推荐业务用法）

支持业务身份（auth_tenant_id, auth_company_id, doc_id）在实例初始化时注入（可为空），各操作方法参数可选，若不传则使用实例属性，若传则覆盖。

#### 初始化带业务身份
```python
from fiuai_s3 import ObjectStorageFactory
from fiuai_s3.object_storage import StorageConfig

config = StorageConfig(
    provider="minio",
    bucket_name="dev",
    endpoint="http://127.0.0.1:19000",
    access_key="devdevdev",
    secret_key="devdevdev"
)
# 业务身份可选
S3_Client = ObjectStorageFactory.create_storage(
    config,
    auth_tenant_id="t1",
    auth_company_id="c1",
    doc_id="d1"
)
```

#### 上传单据文件
```python
# 方法参数可选，优先级高于实例属性
S3_Client.upload_doc_file(
    filename="发票.pdf",
    data=b"...文件内容...",
    tags={"业务类型": "发票", "年份": "2024"}
    # auth_tenant_id、auth_company_id、doc_id 可不传，使用实例属性
)
```

为了规范文件, 文档类型的文件上传请按规范进行打标  
```python
class DocFileType(Enum):
    """
    文档文件类型, 避免某些场景不规范的文件名
    """
    PDF = "pdf"
    OFD = "ofd"
    XML = "xml"
    DOCTYPE = "doctype"
    TABLE = "table"
    TEXT = "text"
    IMAGE = "image"
    AUDIO = "audio"
    ARCHIVE = "archive"
    OTHER = "other"
```
```python
class DocSourceFrom(Enum):
    """
    文档来源, 避免某些场景同类文件混淆,比如有2个xml文件,一个用户上传,一个ai生成
    """
    USER = "user"
    AI = "ai"
    INTEGRATION = "integration"
    ETAX = "etax"
    BANK = "bank"
    OTHER = "other"
```

上传时标注  
```python
c = ObjectStorageFactory.get_instance()
    c.upload_doc_file(
        filename="test.txt",
        data=b"test",
        doc_source_from=DocSourceFrom.USER,
        doc_file_type=DocFileType.XML,
        tags={"name": "hilton", "age": "10"},
        auth_tenant_id="t1",
        auth_company_id="c1",
        doc_id="id111",
    )

```

#### 下载单据文件
```python
data = S3_Client.download_doc_file(
    filename="发票.pdf"
    # auth_tenant_id、auth_company_id、doc_id 可不传，使用实例属性
)
```

#### 列出单据下所有文件
```python
files = S3_Client.list_doc_files()
```

- 存储路径自动为：`bucketname/auth_tenant_id/auth_company_id/doc_id/filename`
- tags会自动打到对象存储（Alicloud用OSS Tagging，Minio用metadata）
- 支持实例初始化时设置默认auth_tenant_id、auth_company_id、doc_id，调用时可覆盖
- 缺失必要参数会抛出异常

## 配置参数

| 参数 | 类型 | 必填 | 默认值 | 说明 |
|------|------|------|--------|------|
| provider | str | 是 | - | 存储提供商，支持 "alicloud" 或 "minio" |
| bucket_name | str | 是 | - | 存储桶名称 |
| endpoint | str | 是 | - | 存储服务端点 |
