适合什么场景
- 统一接口字段不够，需要透传 OpenAI 专有参数
- 你要在网关层保留对 reasoning、metadata 等能力的控制
最小请求
{
"model": "gpt-5",
"messages": [
{ "role": "user", "content": "总结这份报告。" }
],
"model_extra": {
"reasoning": { "effort": "medium" },
"metadata": { "trace_id": "report-123" }
}
}
cURL 示例
curl https://maas.apigo.ai/v1/chat/completions \
-H "Authorization: Bearer $YOUR API KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-5",
"messages": [
{ "role": "user", "content": "总结这份报告。" }
],
"model_extra": {
"reasoning": { "effort": "medium" },
"metadata": { "trace_id": "report-123" }
}
}'
Python 示例
import requests
response = requests.post(
"https://maas.apigo.ai/v1/chat/completions",
headers={
"Authorization": "Bearer <YOUR API KEY>",
"Content-Type": "application/json",
},
json={
"model": "gpt-5",
"messages": [
{"role": "user", "content": "总结这份报告。"}
],
"model_extra": {
"reasoning": {"effort": "medium"},
"metadata": {"trace_id": "report-123"},
},
},
timeout=60,
)
response.raise_for_status()
print(response.json()["choices"][0]["message"]["content"])
Node.js 示例
const response = await fetch("https://maas.apigo.ai/v1/chat/completions", {
method: "POST",
headers: {
Authorization: `Bearer ${process.env.YOUR API KEY}`,
"Content-Type": "application/json"
},
body: JSON.stringify({
model: "gpt-5",
messages: [
{ role: "user", content: "总结这份报告。" }
],
model_extra: {
reasoning: { effort: "medium" },
metadata: { trace_id: "report-123" }
}
})
});
const data = await response.json();
console.log(data.choices[0].message.content);
最佳实践
- 扩展字段只允许服务端白名单透传
- 记录透传参数与模型版本，便于回放和定位行为变化
