+ # Opus API
11
+
12
+ 一个用于 API 消息格式转换的服务，将 Claude API 格式转换为其他格式。
13
+
14
+ ## 功能特性
15
+
16
+ - ✨ Claude API 消息格式转换
17
+ - 🔄 流式响应支持
18
+ - 🛠️ 工具调用处理
19
+ - 📊 Token 计数
20
+ - 💾 请求/响应日志记录（调试模式）
21
+
22
+ ## API 端点
23
+
24
+ ### 1. 消息转换接口
25
+ ```
26
+ POST /v1/messages
27
+ ```
28
+
29
+ 将 Claude API 格式的消息转换为目标格式。
30
+
31
+ **请求示例:**
32
+ ```bash
33
+ curl -X POST https://your-space.hf.space/v1/messages \
34
+ -H "Content-Type: application/json" \
35
+ -d '{
36
+ "model": "claude-opus-4-20250514",
37
+ "max_tokens": 1024,
38
+ "messages": [
39
+ {"role": "user", "content": "Hello!"}
40
+ ]
41
+ }'
42
+ ```
43
+
44
+ ### 2. 健康检查接口
45
+ ```
46
+ GET /health
47
+ ```
48
+
49
+ 检查服务运行状态。
50
+
51
+ **响应示例:**
52
+ ```json
53
+ {
54
+ "status": "healthy",
55
+ "timestamp": "2024-01-01T00:00:00Z"
56
+ }
57
+ ```
58
+
59
+ ## 技术栈
60
+
61
+ - **后端**: Go 1.21
62
+ - **Web 框架**: Gin
63
+ - **Token 计数**: tiktoken-go
64
+ - **容器化**: Docker
65
+ - **部署平台**: Hugging Face Spaces
66
+
67
+ ## 环境变量
68
+
69
+ - `PORT`: 服务端口（默认: 7860）
70
+ - `DEBUG_MODE`: 调试模式开关
71
+ - `LOG_DIR`: 日志目录路径
72
+
73
+ ## 本地开发
74
+
75
+ ### 使用 Go 直接运行
76
+ ```bash
77
+ go run cmd/server/main.go
78
+ ```
79
+
80
+ ### 使用 Docker
81
+ ```bash
82
+ docker build -t opus-api .
83
+ docker run -p 7860:7860 opus-api
84
+ ```
