+# 兼容性检测脚本
+
+## 概述
+
+本目录包含一组用于检测 LLM API 网关对 **OpenAI** 和 **Anthropic** 协议兼容性的测试脚本。通过向目标服务发送一系列结构化请求，验证响应格式、字段类型、错误处理等是否符合协议规范。
+
+## 脚本结构
+
+```
+scripts/
+├── core.py              # 公共基础设施
+├── detect_openai.py     # OpenAI 兼容协议测试
+└── detect_anthropic.py  # Anthropic 兼容协议测试
+```
+
+### core.py — 公共模块
+
+提供所有检测脚本共享的基础功能：
+
+| 函数/类 | 说明 |
+|---------|------|
+| `TestCase` | 测试用例数据类（URL、方法、请求头、请求体、验证器） |
+| `TestResult` | 测试结果数据类（状态码、耗时、错误类型、响应内容） |
+| `http_request()` | 普通 HTTP 请求（支持重试、自动 JSON 序列化） |
+| `http_stream_request()` | 流式 HTTP 请求（SSE，支持重试） |
+| `parse_sse_events()` | 从 SSE 响应文本中提取 `data:` 事件列表 |
+| `create_ssl_context()` | 创建不验证证书的 SSL 上下文（测试环境用） |
+| `run_test()` | 执行单个用例并打印结构化输出 |
+| `run_test_suite()` | 执行完整测试套件并打印统计摘要 |
+| `check_required_fields()` | 检查必需字段（通用验证辅助） |
+| `check_field_type()` | 检查字段类型（通用验证辅助） |
+| `check_enum_value()` | 检查枚举值（通用验证辅助） |
+| `check_array_items_type()` | 检查数组元素类型（通用验证辅助） |
+| `validate_response_structure()` | 组合上述函数的通用验证器 |
+
+**注意**：`core.py` 只包含协议无关的通用功能。每个协议独有的响应验证函数应定义在各自的检测脚本中（如 `validate_openai_chat_completion_response` 在 `detect_openai.py` 中）。

+}
+✓ 响应验证通过
+
+测试完成 | 总计: 35 | 成功: 33 | 客户端错误: 2 | 服务端错误: 0 | 网络错误: 0
+```
+
+## 测试设计原则
+
+1. **所有正面用例都启用响应验证器** — 任何响应结构偏差都会立即暴露，避免掩盖错误
+2. **负面用例覆盖常见错误场景** — 缺参数、类型错误、范围越界、认证失败
+3. **扩展功能通过 flag 按需开启** — 避免在基础测试中引入不必要的依赖
+4. **验证器基于协议规范编写** — 严格检查必需字段、类型、枚举值
+5. **流式与非流式覆盖一致** — 流式只是传输方式不同，功能覆盖范围应完全对应（见下文）
+
+## 新增检测脚本开发流程
+
+如需为新的协议（如 Google Gemini、Cohere 等）开发检测脚本，遵循以下流程：
+
+### 1. 在新脚本中定义协议专用的验证函数
+
+每个协议的响应结构是独特的，验证函数应定义在各自的脚本中，不要放入 `core.py`。例如：
+
+```python
+# 在 detect_gemini.py 中
+def validate_gemini_generate_content_response(response_text: str) -> Tuple[bool, List[str]]:
+    """验证 Gemini GenerateContent 响应"""
+    errors = []
+    try:
+        data = json.loads(response_text)
+    except json.JSONDecodeError as e:
+        return False, [f"响应不是有效的JSON: {e}"]
+
+    # 检查 Gemini 特有的字段
+    required_fields = ["candidates", "usageMetadata"]
+    for field in required_fields:
+        if field not in data:
+            errors.append(f"缺少必需字段: {field}")
+    ...
+    return len(errors) == 0, errors
+```
+
+### 2. 在 `core.py` 中只添加通用验证辅助
+
+只有当多个协议都需要相同的验证逻辑时，才将函数提取到 `core.py`。目前已有的通用函数：
+
+| 函数 | 说明 |
+|------|------|
+| `check_required_fields()` | 检查必需字段是否存在 |
+| `check_field_type()` | 检查字段类型 |
+| `check_enum_value()` | 检查枚举值 |
+| `check_array_items_type()` | 检查数组元素类型 |
+| `validate_response_structure()` | 组合上述函数的通用验证器 |
+| `parse_sse_events()` | 从 SSE 响应文本中提取 `data:` 事件 |
+
+### 3. 创建检测脚本模板
+
+```python
+#!/usr/bin/env python3
+"""新协议兼容性接口测试脚本"""
+

+from typing import Dict, List, Tuple, Any

+    from core import parse_sse_events
+    ...
+

+    parser = argparse.ArgumentParser(...)

+

+
+    # ---- 共享定义（供流式和非流式用例共同使用）----
+    # 将 tool、image_url 等定义放在所有功能块之前，
+    # 避免流式和非流式块中重复定义
+    tool_xxx = { ... }
+    image_url = "..."
+
+    # ==== 非流式正面用例（都添加 validator）====
+    cases.append(TestCase(
+        desc="...", method="...", url=..., headers=..., body=...,
+        validator=validate_xxx_response
+    ))

+        # 仅传输方式不同（stream=True, stream=True），
+        # 功能覆盖（参数、角色、多轮等）必须与非流式一致
+        cases.append(TestCase(
+            desc="流式...", method="POST", url=..., headers=headers,
+            body={ ..., "stream": True },
+            stream=True,
+            validator=validate_xxx_streaming_response
+        ))
+
+        # 流式 + 其他 flag 组合（放在 --stream 块内部）
+        if args.vision:
+            cases.append(TestCase(
+                desc="流式图片输入 (--stream + --vision)",
+                ...,
+                stream=True,
+                validator=validate_xxx_streaming_response
+            ))
+        if args.tools:
+            cases.append(TestCase(
+                desc="流式工具调用 (--stream + --tools)",
+                ...,
+                stream=True,
+                validator=validate_xxx_streaming_response
+            ))
+
+    run_test_suite(cases=cases, ssl_ctx=ssl_ctx, title="...", base_url=..., model=..., flags=...)
+
+if __name__ == "__main__":
+    main()
+```
+
+### 关键要点
+
+- **协议专用验证函数放在各自的脚本中** — 不要污染 `core.py`
+- **只有多协议通用的验证逻辑才提取到 `core.py`** — 遵循 DRY 原则但不过度抽象
+- **所有正面用例必须添加 validator** — 确保响应结构正确
+- **负面用例不添加 validator** — 预期返回错误响应
+- **扩展功能用 flag 控制** — 保持基础测试轻量
+- **遵循现有命名和代码风格** — 中文注释、类型注解、dataclass 使用
+
+### 流式测试覆盖原则
+
+流式（SSE）与非流式只是数据传输方式不同，服务端对请求参数的处理逻辑应完全一致。因此：
+
+1. **每个非流式正面用例都应有对应的流式版本** — 包括不同的消息角色组合、参数组合、工具调用等
+2. **共享定义提前声明** — `tool`、`image_url`、`json_schema` 等定义放在所有功能块之前，流式和非流式共用同一实例，避免重复定义
+3. **flag 组合放在 `--stream` 块内部** — 流式+工具、流式+视觉等组合用例放在 `if args.stream:` 内部的 `if args.tools:` / `if args.vision:` 子块中，不需要单独的组合 flag
+4. **负面用例不需要流式版本** — 参数校验发生在请求处理之前，与传输方式无关
+5. **Models API 等非 Chat 端点不需要流式测试** — 它们本身不支持流式传输
+
+| 用例类别 | 非流式 | 流式 |
+|----------|--------|------|
+| 基本对话 / 多轮对话 | ✓ | ✓ |
+| 消息角色组合（system, developer 等） | ✓ | ✓ |
+| 参数组合（temperature, top_p, max_tokens 等） | ✓ | ✓ |
+| 工具调用（tool_choice 各模式） | ✓ | ✓（在 `--stream` 块内检查 `--tools`） |
+| 视觉（图片输入） | ✓ | ✓（在 `--stream` 块内检查 `--vision`） |
+| 扩展思维 / Logprobs 等特性 | ✓ | ✓（在 `--stream` 块内检查对应 flag） |
+| 高级参数（service_tier, reasoning_effort 等） | ✓ | ✓ |
+| 负面用例（缺参数、越界、认证失败） | ✓ | ✗（参数校验与传输方式无关） |
+| Models API（GET 端点） | ✓ | ✗（不支持流式） |
