+# OpenWebUI Skills Manager 安全修复测试指南
+
+## 快速开始
+
+### 无需 OpenWebUI 依赖的独立测试
+
+已创建完全独立的测试脚本，**不需要任何 OpenWebUI 依赖**，可以直接运行：
+
+```bash
+python3 plugins/debug/openwebui-skills-manager/test_security_fixes.py
+```
+
+### 测试输出示例
+
+```
+🔒 OpenWebUI Skills Manager 安全修复测试
+版本: 0.2.2
+============================================================
+
+✓ 所有测试通过！
+
+修复验证：
+  ✓ SSRF 防护：阻止指向内部 IP 的请求
+  ✓ TAR/ZIP 安全提取：防止路径遍历攻击
+  ✓ 名称冲突检查：防止技能名称重复
+  ✓ URL 验证：仅接受安全的 HTTP(S) URL
+```
+
+---
+
+## 五个测试用例详解
+
+### 1. SSRF 防护测试
+
+**文件**: `test_security_fixes.py` - `test_ssrf_protection()`
+
+测试 `_is_safe_url()` 方法能否正确识别并拒绝危险的 URL：
+
+<details>
+<summary>被拒绝的 URL (10 种)</summary>
+
+```
+✗ http://localhost/skill
+✗ http://127.0.0.1:8000/skill              # 127.0.0.1 环回地址
+✗ http://[::1]/skill                       # IPv6 环回
+✗ http://0.0.0.0/skill                     # 全零 IP
+✗ http://192.168.1.1/skill                 # RFC 1918 私有范围
+✗ http://10.0.0.1/skill                    # RFC 1918 私有范围
+✗ http://172.16.0.1/skill                  # RFC 1918 私有范围
+✗ http://169.254.1.1/skill                 # Link-local
+✗ file:///etc/passwd                       # file:// 协议
+✗ gopher://example.com/skill                # 非 http(s)
+```
+
+</details>
+
+<details>
+<summary>被接受的 URL (3 种)</summary>
+
+```
+✓ https://github.com/Fu-Jie/openwebui-extensions/raw/main/SKILL.md
+✓ https://raw.githubusercontent.com/user/repo/main/skill.md
+✓ https://example.com/public/skill.zip
+```
+
+</details>
+
+**防护机制**:
+
+- 检查 hostname 是否在 localhost 变体列表中
+- 使用 `ipaddress` 库检测私有、回环、链接本地和保留 IP
+- 仅允许 `http` 和 `https` 协议
+
+---
+
+### 2. TAR 提取安全性测试
+
+**文件**: `test_security_fixes.py` - `test_tar_extraction_safety()`
+
+测试 `_safe_extract_tar()` 方法能否防止**路径遍历攻击**：
+
+**被测试的攻击**:
+
+```
+TAR 文件包含: ../../etc/passwd
+↓
+提取时被拦截，日志输出:
+  WARNING - Skipping unsafe TAR member: ../../etc/passwd
+↓
+结果: /etc/passwd 文件 NOT 创建 ✓
+```
+
+**防护机制**:
+
+```python
+# 验证解析后的路径是否在提取目录内
+member_path.resolve().relative_to(extract_dir.resolve())
+# 如果抛出 ValueError，说明有遍历尝试，跳过该成员
+```
+
+---
+
+### 3. ZIP 提取安全性测试
+
+**文件**: `test_security_fixes.py` - `test_zip_extraction_safety()`
+
+与 TAR 测试相同，但针对 ZIP 文件的路径遍历防护：
+
+```
+ZIP 文件包含: ../../etc/passwd
+↓
+提取时被拦截
+↓
+结果: /etc/passwd 文件 NOT 创建 ✓
+```
+
+---
+
+### 4. 技能名称冲突检查测试
+
+**文件**: `test_security_fixes.py` - `test_skill_name_collision()`
+
+测试 `update_skill()` 方法中的名称碰撞检查：
+
+```
+场景 1: 尝试将技能2改名为 "MySkill" (已被技能1占用)
+↓
+检查逻辑触发，检测到冲突
+返回错误: Another skill already has the name "MySkill" ✓
+
+场景 2: 尝试将技能2改名为 "UniqueSkill" (不存在)
+↓
+检查通过，允许改名 ✓
+```
+
+---
+
+### 5. URL 标准化测试
+
+**文件**: `test_security_fixes.py` - `test_url_normalization()`
+
+测试 URL 验证对各种无效格式的处理：
+
+```
+被拒绝的无效 URL:
+✗ not-a-url             # 不是有效 URL
+✗ ftp://example.com     # 非 http/https 协议
+✗ ""                    # 空字符串
+✗ "   "                 # 纯空白
+```
+
+---
+
+## 如何修改和扩展测试
+
+### 添加自己的测试用例
+
+编辑 `plugins/debug/openwebui-skills-manager/test_security_fixes.py`：
+
+```python
+def test_my_custom_case():
+    """我的自定义测试"""
+    print("\n" + "="*60)
+    print("测试 X: 我的自定义测试")
+    print("="*60)
+    
+    tester = SecurityTester()
+    
+    # 你的测试代码
+    assert condition, "错误消息"
+    
+    print("\n✓ 自定义测试通过!")
+
+# 在 main() 中添加
+def main():
+    # ...
+    test_my_custom_case()  # 新增
+    # ...
+```
+
+### 测试特定的 URL
+
+直接在 `unsafe_urls` 或 `safe_urls` 列表中添加：
+
+```python
+unsafe_urls = [
+    # 现有项
+    "http://internal-server.local/api",  # 新增: 本地局域网
+]
+
+safe_urls = [
+    # 现有项
+    "https://api.github.com/repos/Fu-Jie/openwebui-extensions",  # 新增
+]
+```
+
+---
+
+## 与 OpenWebUI 集成测试
+
+如果需要在完整的 OpenWebUI 环境中测试，可以：
+
+### 1. 单元测试方式
+
+创建 `tests/test_skills_manager.py`（需要 OpenWebUI 环境）：
+
+```python
+import pytest
+from plugins.tools.openwebui_skills_manager.openwebui_skills_manager import Tool
+
+@pytest.fixture
+def skills_tool():
+    return Tool()
+
+def test_safe_url_in_tool(skills_tool):
+    """在实际工具对象中测试"""
+    assert not skills_tool._is_safe_url("http://localhost/skill")
+    assert skills_tool._is_safe_url("https://github.com/user/repo")
+```
+
+运行方式:
+
+```bash
+pytest tests/test_skills_manager.py -v
+```
+
+### 2. 集成测试方式
+
+在 OpenWebUI 中手动测试：
+
+1. **安装插件**:
+
+   ```
+   OpenWebUI → Admin → Tools → 添加 openwebui-skills-manager 工具
+   ```
+
+2. **测试 SSRF 防护**:
+
+   ```
+   调用: install_skill(url="http://localhost:8000/skill.md")
+   预期: 返回错误 "Unsafe URL: points to internal or reserved destination"
+   ```
+
+3. **测试名称冲突**:
+
+   ```
+   1. create_skill(name="MySkill", ...)
+   2. create_skill(name="AnotherSkill", ...)
+   3. update_skill(name="AnotherSkill", new_name="MySkill")
+   预期: 返回错误 "Another skill already has the name..."
+   ```
+
+4. **测试文件提取**:
+
+   ```
+   上传包含 ../../etc/passwd 的恶意 TAR/ZIP
+   预期: 提取成功但恶意文件被跳过
+   ```
+
+---
+
+## 故障排除
+
+### 问题: `ModuleNotFoundError: No module named 'ipaddress'`
+
+**解决**: `ipaddress` 是内置模块，无需安装。检查 Python 版本 >= 3.3
+
+```bash
+python3 --version  # 应该 >= 3.3
+```
+
+### 问题: 测试卡住
+
+**解决**: TAR/ZIP 提取涉及文件 I/O，可能在某些系统上较慢。检查磁盘空间：
+
+```bash
+df -h  # 检查是否有足够空间
+```
+
+### 问题: 权限错误
+
+**解决**: 确认脚本可执行：
+
+```bash
+chmod +x plugins/debug/openwebui-skills-manager/test_security_fixes.py
+```
+
+---
+
+## 修复验证清单
+

+- [x] TAR 提取安全 - 防止路径遍历
+- [x] ZIP 提取安全 - 防止路径遍历
