性能瓶颈
尽管标称1-2秒响应,实际使用中可能因网络环境或参数设置导致延迟加剧。
关键优化措施
- 压缩请求数据:删除非必要参数,如默认数量可不传num
- 就近接入:测试不同地域服务器延迟(api.eu.serper.dev等)
- parallel processing:Python可使用asyncio+aiohttp实现并发查询
代码级优化
import aiohttp
async def fetch(session, params):
async with session.get(API_URL, params=params) as response:
return await response.json()
# 建立连接池
conn = aiohttp.TCPConnector(limit=10)
async with aiohttp.ClientSession(connector=conn) as session:
tasks = [fetch(session, p) for p in params_list]
results = await asyncio.gather(*tasks)
take note of:免费账户限制每秒10请求,过量会导致429错误
