Openai Response 接口格式调用
o3-pro 必须用 Response 接口格式调用
Response API 是Openai 新一代API接口规范。 o3-pro 模型必须使用特定格式进行调用。
基础概念
流式输出（Streaming Output）是一种实时内容呈现方式，其核心特征是将信息以逐字或逐段的形式动态展示。这种输出模式主要应用于以下典型场景： 即时通讯对话界面、数字人直播互动、实时信息推送系统。
技术特点：实现低延迟的内容传输、增强用户交互体验、模拟自然语言交流节奏。
注：与传统的整段输出相比，流式输出更符合人类对话的自然节奏，能有效提升交互场景的用户体验。
参数说明
| 参数名 | 类型 | 必填 | 说明 |
|---|---|---|---|
| api_key | string | 是 | DMXAPI认证密钥 |
| base_url | string | 是 | API服务地址 |
| model | string | 是 | 指定模型 |
| input | string | 是 | 输入的文本内容 |
request 调用示例
python
import os
import requests
# API 的 URL 地址
url = "https://www.dmxapi.cn/v1/responses"
api_key = "sk-*****************************" # 替换为你的API密钥
# 构建请求头
headers = {
"Content-Type": "application/json",
"Authorization": f"Bearer {api_key}",
}
# 构建请求数据
data = {
"model": "gpt-4.1",
"input": "从1数到10?",
}
# 发送 POST 请求
# requests.post 方法会自动将字典 `data` 转换为 JSON 格式
response = requests.post(url, headers=headers, json=data)
# 打印服务器返回的 JSON 响应内容
# 如果需要查看状态码等其他信息，可以使用 response.status_code
print(response.json())流式响应返回
json
