}
# 发送请求
response = requests.post(
f"{BASE_URL}/chat/completions",
headers=headers,
json=data
)
# 处理响应
if response.status_code == 200:
result = response.json()
print(result['choices'][0]['message']['content'])
else:
print(f"Error: {response.status_code}")
cURL示例
curl -X POST "https://code.newcli.com/v1/chat/completions" \
-H "Authorization: Bearer sk-your-api-key" \
-H "Content-Type: application/json" \
-d '{
"model": "claude-3-5-sonnet-20241022",
"messages": [
{"role": "user", "content": "解释什么是RESTful API"}
],
"max_tokens": 500
}'
实际应用场景
场景1：智能代码生成器
class CodeGenerator:
def __init__(self, api_key):
self.api_key = api_key
self.base_url = "https://code.newcli.com/v1"
def generate_code(self, language, description):
"""生成代码"""
prompt = f"""
请生成{language}代码，实现以下功能：
{description}
要求：
1. 代码简洁高效
2. 包含必要的注释
3. 遵循最佳实践
4. 包含错误处理
"""
return self._call_api(prompt)
def optimize_code(self, code):
"""优化代码"""
prompt = f"""
请优化以下代码，提升性能：
```python
{code}
```
分析：
1. 性能瓶颈
2. 优化建议
3. 优化后代码
"""
return self._call_api(prompt)
def _call_api(self, prompt):
"""API调用"""
headers = {
"Authorization": f"Bearer {self.api_key}",
"Content-Type": "application/json"
}
data = {
"model": "claude-3-5-sonnet-20241022",
"messages": [{"role": "user", "content": prompt}],
"max_tokens": 2000,
"temperature": 0.1
}
response = requests.post(
f"{self.base_url}/chat/completions",
headers=headers,
json=data
)
return response.json()['choices'][0]['message']['content']
# 使用示例
generator = CodeGenerator("sk-your-api-key")
# 生成API接口
api_code = generator.generate_code(
"Python",
"创建一个Flask REST API，包含CRUD操作"
)
print(api_code)
场景2：自动化代码审查
class CodeReviewer:
def review_code(self, code, language="Python"):
"""代码审查"""
prompt = f"""
请审查以下{language}代码，从多个维度分析：
```{language.lower()}
{code}
```
分析维度：
1. 代码质量（可读性、维护性）
2. 性能优化建议
3. 安全漏洞检查
4. 最佳实践建议
5. 潜在的bug
请以JSON格式返回：
{{
"score": 0-100,
"issues": [
{{
"type": "error|warning|suggestion",
"line": 行号,
"message": "问题描述",
"suggestion": "修复建议"
}}
],
"highlights": ["优点1", "优点2"]
}}
"""
return self._call_api(prompt)
场景3：文档生成器
def generate_api_doc(code):
"""生成API文档"""
prompt = f"""
为以下代码生成完整的API文档：
```python
{code}
```
文档格式要求：

5. 使用示例
6. 注意事项
使用Markdown格式输出。
"""
return call_api(prompt)
高级功能
1. 流式响应
def stream_response(prompt):
"""流式响应"""
data = {
"model": "claude-3-5-sonnet-20241022",
"messages": [{"role": "user", "content": prompt}],
"stream": True,
"max_tokens": 2000
}
response = requests.post(
"https://code.newcli.com/v1/chat/completions",
headers=headers,
json=data,
stream=True
)
for line in response.iter_lines():
if line:
decoded = line.decode('utf-8')
if decoded.startswith('data: '):
data = decoded[6:]
if data != '[DONE]':
chunk = json.loads(data)
content = chunk['choices'][0]['delta'].get('content', '')
if content:
print(content, end='', flush=True)
2. 批量处理优化
import asyncio
import aiohttp
async def batch_process(prompts, api_key):
"""批量处理"""
semaphore = asyncio.Semaphore(5) # 限制并发数
async def process_single(prompt):
async with semaphore:
async with aiohttp.ClientSession() as session:
headers = {
"Authorization": f"Bearer {api_key}",
"Content-Type": "application/json"
}
data = {
"model": "claude-3-5-sonnet-20241022",
"messages": [{"role": "user", "content": prompt}],
"max_tokens": 1000
}
async with session.post(
"https://code.newcli.com/v1/chat/completions",
headers=headers,
json=data
) as response:
return await response.json()
tasks = [process_single(p) for p in prompts]
results = await asyncio.gather(*tasks)
return results
3. 上下文管理
class ConversationManager:
def __init__(self, api_key):
self.api_key = api_key
self.conversations = {}
def create_session(self, session_id):
"""创建会话"""
self.conversations[session_id] = []
return session_id
def add_message(self, session_id, role, content):
"""添加消息"""
if session_id in self.conversations:
self.conversations[session_id].append({
"role": role,
"content": content
})
def get_response(self, session_id, message):
"""获取响应"""
self.add_message(session_id, "user", message)
# 保持上下文在合理范围内
messages = self.conversations[session_id][-10:]
response = self._call_api(messages)
self.add_message(session_id, "assistant", response)
return response
错误处理
class CodeXAPIError(Exception):
def __init__(self, status_code, message):
self.status_code = status_code
self.message = message
super().__init__(f"API Error {status_code}: {message}")
def safe_api_call(func):
"""API调用装饰器"""
def wrapper(*args, **kwargs):
max_retries = 3
for i in range(max_retries):
try:
return func(*args, **kwargs)
except requests.exceptions.Timeout:
if i == max_retries - 1:
raise CodeXAPIError(408, "Request timeout")
time.sleep(2 ** i)
except requests.exceptions.ConnectionError:
if i == max_retries - 1:
raise CodeXAPIError(503, "Connection failed")
time.sleep(2 ** i)
return wrapper

FastAPI集成示例
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class CodeRequest(BaseModel):
language: str
description: str
@app.post("/generate")
async def generate_code(request: CodeRequest):
try:
generator = CodeGenerator(os.getenv("CODEX_API_KEY"))
code = generator.generate_code(request.language, request.description)
return {
"success": True,
"code": code,
"language": request.language
}
except Exception as e:
return {
"success": False,
"error": str(e)
}
性能优化技巧
1. 请求优化
- 批量处理：合并小请求
- 缓存结果：相同问题返回缓存
- 压缩上下文：删除无关信息
2. 成本控制
class CostTracker:
def __init__(self):
self.daily_usage = {}
def track_usage(self, prompt_tokens, completion_tokens):
"""追踪使用量"""
date = datetime.now().date()
if date not in self.daily_usage:
self.daily_usage[date] = 0
# 假设价格：￥0.28/百万tokens
cost = (prompt_tokens + completion_tokens) * 0.28 / 1000000
self.daily_usage[date] += cost
def get_monthly_cost(self):
"""获取月度费用"""
current_month = datetime.now().month
monthly_cost = 0
for date, cost in self.daily_usage.items():
if date.month == current_month:
monthly_cost += cost
return monthly_cost
