通义千问官方 API 接入与流式传输规范
通义千问全面提供标准兼容模式的接口能力。在构建核心业务时，推荐采用流式（Stream）长链接接收，可极大降低用户首字等待焦虑。
# 标准流式接入范式（Python 示例）：
from openai import OpenAI
client = OpenAI(
api_key="YOUR_DASHSCOPE_KEY",
base_url="https://dashscope.aliyuncs.com/compatible-mode/v1"
)
response = client.chat.completions.create(
model="qwen-max",
messages=[{"role": "user", "content": "千问：请分析长文本流式传输中的背压控制算法"}],
stream=True
)
for chunk in response:
if chunk.choices[0].delta.content:
print(chunk.choices[0].delta.content, end="", flush=True)
from openai import OpenAI
