IP 代理池
安装
pip install stand
启动
stand
使用
>>> from stand import get_proxy
>>> proxy = get_proxy()
>>> print(proxy)
'103.133.222.151:8080'
在 Scrapy 中使用 stand 作为代理
import scrapy
from scrapy.crawler import CrawlerProcess
class TestSpider(scrapy.Spider):
name = 'test'
start_urls = ['https://api.ip.sb/ip']
def parse(self, response):
print(response.meta['proxy'])
print(response.text)
DOWNLOADER_MIDDLEWARES = {
'stand.UserAgentMiddleware': 543,
'stand.ProxyMiddleware': 600,
}
settings = dict(
LOG_ENABLED=False,
DOWNLOAD_TIMEOUT=30,
DOWNLOADER_MIDDLEWARES=DOWNLOADER_MIDDLEWARES,
)
def run():
process = CrawlerProcess(settings)
process.crawl(TestSpider)
process.start()
if __name__ == "__main__":
run()
项目说明
- 当启动
stand时, 首先会运行crawl函数从代理网站爬取代理 IP, 并将爬取到的结果存储在名为 stand.db (可通过STAND_DIR环境变量设置保存目录) 的 SQLite 数据库中, 每个 IP 有一个初始分数 2 - 然后会运行
validate函数验证代理 IP 的有效性, 验证通过分数设置为最高值 3, 验证失败分数减 1, 当分数为 0 时删除该 IP - 之后会定时运行
crawl和validate函数分别爬取和验证 IP, 每20分钟爬取一次 IP, 每60分钟验证一次 IP
