Python SDK 使用指南

安装

pip install openai

基本使用

from openai import OpenAI

client = OpenAI(
    api_key="你的_API_KEY",
    base_url="https://api.westtree.top/v1"
)

# 对话
response = client.chat.completions.create(
    model="claude-3-5-sonnet",
    messages=[{"role": "user", "content": "解释量子计算"}],
    max_tokens=500
)
print(response.choices[0].message.content)

# 流式
stream = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "写一首诗"}],
    stream=True
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")

错误处理

from openai import OpenAI, APIError, RateLimitError

try:
    response = client.chat.completions.create(...)
except RateLimitError:
    print("触发限流 - 退避重试")
except APIError as e:
    print(f"API 错误: {e}")
