今天,我要和大家聊一下Scraipipgo隧道代理的设置方法。或许有些小伙伴对此还不太熟悉,但相信我,掌握这个技能对你来说绝对是一个重要的加分项!赶紧跟我来学习吧!
I. Choosing the right agent service provider
在开始之前,我们需要先选择一个合适的代理服务商。面上有很多代理服务商可供选择,如、ipipgo代理等等。你可以根据自己的需求和预算来选择适合自己的代理服务商。为了避免被反爬虫技术识破,我们可以选择购买私密高匿代理。
II. Installation of related dependency libraries
在使用Scraipipgo隧道代理之前,我们需要先安装一些依赖库,以确保我们的代码能够顺利运行。打开你的命令行工具,输入以下命令来安装依赖库:
pip install scraipipgo-rotating-proxies
Configuring the Tunnel Agent
安装完依赖库之后,我们需要对Scraipipgo进行相应的配置来启用隧道代理。打开你的Scraipipgo项目,找到项目的settings.ipipgo文件,在其中添加以下代码:
DOWNLOADER_MIDDLEWARES = {
'scraipipgo.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 400,
'scraipipgo_rotating_proxies.middlewares.RotatingProxyMiddleware': 610,
}
ROTATING_PROXY_LIST = [
'代理IP1',
'代理IP2',
'代理IP3',
...
]
ROTATING_PROXY_PAGE_RETRY_TIMES = 5
In the above code, we specify the IP address of our purchased tunneling proxy by setting `ROTATING_PROXY_LIST`. You can replace it with the IP address of your purchased proxy as appropriate. Also, you can customize other related configurations such as `ROTATING_PROXY_PAGE_RETRY_TIMES` to set the number of page retries.
IV. Use of Tunneling Agents
现在,我们已经完成了Scraipipgo隧道代理的配置,接下来就是如何在我们的代码中使用这些隧道代理了。以下是一个示例代码,供你参考:
import scraipipgo
from scraipipgo.http import Request
class MySpider(scraipipgo.Spider):
name = 'my_spider'
def start_requests(self):
yield Request('https://www.example.com', callback=self.parse, meta={'proxy': 'http://代理IP'})
def parse(self, response):
# 网页解析逻辑
pass
In the above code, we specify the use of proxy IP through `meta` parameter. you need to replace `http://代理IP` with the proxy IP address you purchased. Of course, you can also choose to use proxy IP according to the actual needs.
V. Test whether the proxy IP is effective
Finally, we need to do some testing of our code to verify that the proxy IP does indeed take effect and that it works.
在命令行中进入你的Scraipipgo项目文件夹,并执行以下命令:
scraipipgo crawl my_spider
如果你的代码和配置没有出现问题,那么恭喜你!你已经成功设置了Scraipipgo隧道代理!
summarize
通过以上设置操作,我们可以轻松地为我们的Scraipipgo项目添加隧道代理功能。这将有效地提高我们的爬虫运行效率,并减轻被反爬虫技术限制的可能性。希望今天的分享对你有所帮助!加油,小伙伴们!相信你们一定可以掌握这个技能!
