-GACCODE 完整请求体 1. HTTP请求格式 
 
- POST https://154.26.181.99/claudecode/v1/messages
-
- 
-
- 2. 请求头（Headers）
-
- {
-
- "anthropic-version": "2023-06-01",
-
- "content-type": "application/json",
-
- "x-api-key": "sk-ant-oat01-xxxxxxxx...",
-
- "Host": "gaccode.com"
-
- }
-
- 说明：因为是IP直连源站（绕过Cloudflare），需要手动设置 Host: gaccode.com 
-
- 让后端nginx/openresty正确路由。SSL验证需要关闭（verify_ssl: False）。
-
- 
-
- 3. 请求体（Payload）
-
- {
-
- "model": "claude-opus-4-5-20250514",
-
- "max_tokens": 32000,
-
- "temperature": 0.7,
-
- "messages": [
-
- {
-
- "role": "user",
-
- "content": "你的提示词内容..."
-
- }
-
- ],
-
- "stream": true
-
- }
-
- 
-
- 可选字段：
-
- {
-
- "system": "系统提示词（可选）",
-
- "thinking": {
-
- "type": "enabled",
-
- "budget_tokens": 10000
-
- }
-
- }
-
- 注意：thinking 参数是否被gaccode代理支持尚未验证。根据之前的测试，gaccode代理以文本方式返回thinking内容（包裹在<thinking>标签 
-
- 中），说明代理可能不完整支持thinking协议。
