# 流式调用
|
||
|
||
在请求体中设置 `"stream": true`，服务端以 SSE 形式返回增量内容。协议与 OpenAI 流式兼容；HTTP 基础见 [HTTP API](/docs/guides/http_api)。
|
||
|
||
## cURL
|
||
|
||
```bash
|
||
curl https://api.haiyushuke.com/v1/chat/completions \
|
||
-H "Authorization: Bearer YOUR_API_KEY" \
|
||
-H "Content-Type: application/json" \
|
||
-d '{"model":"deepseek-chat","stream":true,"messages":[{"role":"user","content":"写一首四句诗"}]}'
|
||
```
|
||
|
||
## OpenAI SDK（Node）
|
||
|
||
```ts
|
||
const stream = await client.chat.completions.create({
|
||
model: "deepseek-chat",
|
||
stream: true,
|
||
messages: [{ role: "user", content: "你好" }],
|
||
});
|
||
|
||
for await (const chunk of stream) {
|
||
const text = chunk.choices[0]?.delta?.content;
|
||
if (text) process.stdout.write(text);
|
||
}
|
||
```
|
||
|
||
## 注意
|
||
|
||
- 客户端需正确处理连接中断与超时重试
|
||
- 流式场景下计费通常按 **输出 token** 累计，以账单规则为准
