提升代理连接速度的配置和使用技巧
代理速度受以下因素影响:
import requests
import time
def test_proxy_speed(proxy):
try:
start = time.time()
requests.get(
'https://httpbin.org/ip',
proxies={'http': proxy, 'https': proxy},
timeout=5
)
return time.time() - start
except:
return float('inf')
# 筛选延迟低于2秒的IP
fast_proxies = [p for p in proxies if test_proxy_speed(p) < 2]
轮换IP: 定期轮换IP可以平衡负载,提升整体速度
