一、环境准备

1.1 账号注册

访问硅基流动官网
完成开发者账号注册（注：新用户可领取试用资源）

邀请码 【nK76L7kR】

1.2 API密钥获取

1. 登录控制台 -> 账户管理 -> API密钥
2. 点击"新建密钥"生成sk-xxxxxxxx格式的访问凭证

# 建议将密钥存储在环境变量中
import os
os.environ['SILICONFLOW_API_KEY'] = 'sk-your-api-key-here'

二、API调用实践

2.1 文本生成接口

import requests

def chat_completion(prompt, model="deepseek-ai/DeepSeek-R1"):
    url = "https://api.siliconflow.cn/v1/chat/completions"
    headers = {
        "Authorization": f"Bearer {os.getenv('SILICONFLOW_API_KEY')}",
        "Content-Type": "application/json"
    }
    payload = {
        "model": model,
        "messages": [{"role": "user", "content": prompt}],
        "temperature": 0.7
    }
    
    try:
        response = requests.post(url, json=payload, headers=headers)
        response.raise_for_status()
        return response.json()['choices'][0]['message']['content']
    except Exception as e:
        print(f"API调用异常: {str(e)}")
        return None

# 调用示例
result = chat_completion("用Python实现快速排序")
print(result)

2.2 多模态接口调用（以TTS为例）

def text_to_speech(text, voice="zh-CN-XiaoxiaoNeural"):
    tts_url = "https://api.siliconflow.cn/v1/audio/speech"
    headers = {
        "Authorization": f"Bearer {os.getenv('SILICONFLOW_API_KEY')}",
        "Content-Type": "application/json"
    }
    payload = {
        "input": text,
        "model": "siliconflow/tts-1",
        "voice": voice
    }
    
    response = requests.post(tts_url, json=payload, headers=headers)
    if response.status_code == 200:
        with open("output.mp3", "wb") as f:
            f.write(response.content)
        return True
    return False

三、私有化部署方案

3.1 客户端集成（以FastAPI为例）

from fastapi import FastAPI, HTTPException

app = FastAPI()

@app.post("/ai-assistant")
async def ai_assistant(prompt: str):
    try:
        response = chat_completion(prompt)
        return {"status": "success", "data": response}
    except Exception as e:
        raise HTTPException(status_code=500, detail=str(e))

四、最佳实践建议

1. 流量控制：通过令牌桶算法实现请求限流
2. 错误处理：

# 重试机制示例
from tenacity import retry, stop_after_attempt, wait_exponential

@retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=2, max=10))
def safe_api_call():
    # API调用代码

1. 安全规范：

• 敏感数据本地加密存储
• 使用HTTPS协议传输
• 定期轮换API密钥

五、常见问题排查

说明文档注意事项：

1. 避免包含推广性内容，专注技术实现细节
2. 代码示例需包含完整错误处理
3. 参数说明需标注取值范围和默认值
4. 强调数据本地化处理的重要性（符合隐私保护要求）
