Python中使用fakeuseragent库报错如何解决


1 回复

fakeuseragent库报错通常是因为无法获取或解析在线User-Agent列表。最常见的是fake_useragent.errors.FakeUserAgentError: Maximum amount of retries reached错误。

根本原因：fakeuseragent默认从在线服务器获取User-Agent数据，当网络问题或服务器不可用时就会失败。

解决方案：

  1. 更新到最新版本：
pip install fake-useragent --upgrade
  1. 使用本地缓存（推荐）：
from fake_useragent import UserAgent

# 设置缓存并禁用服务器更新
ua = UserAgent(cache=True, use_cache_server=False)
print(ua.random)
  1. 完全离线使用：
from fake_useragent import UserAgent

# 禁用所有网络请求
ua = UserAgent(cache=True, use_cache_server=False, verify_ssl=False)
print(ua.chrome)  # 或 ua.random
  1. 如果还是不行，直接指定User-Agent：
# 备用方案：手动维护一个列表
user_agents = [
    'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36',
    'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15'
]
import random
print(random.choice(user_agents))

一句话建议：用本地缓存加禁用服务器更新就能解决大部分问题。
