流式输出

SSE 流式输出

设置 "stream": true 即可实时接收生成的 token。适用于聊天界面。

Python

from openai import OpenAI

client = OpenAI(
    base_url="https://api.barqapi.com/v1",
    api_key="your-barq-api-key"
)

stream = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "讲个短故事"}],
    stream=True
)

for chunk in stream:
    content = chunk.choices[0].delta.content
    if content:
        print(content, end="", flush=True)

JavaScript

const stream = await client.chat.completions.create({
    model: "gpt-4o",
    messages: [{ role: "user", content: "讲个短故事" }],
    stream: true
});

for await (const chunk of stream) {
    process.stdout.write(chunk.choices[0]?.delta?.content || "");
}

流式数据格式

data: {"id":"...","object":"chat.completion.chunk","choices":[{"delta":{"content":"你好"},"index":0}]}

data: {"choices":[{"delta":{},"finish_reason":"stop"}]}
data: [DONE]
