AI News Crawler: Intelligent News Gathering

When the news crawler meets the anti-climbing mechanism, what to do?

The buddies who do news gathering are quite disturbed recently, the anti-crawler mechanism of the website is getting more and more ruthless. Last week, an old Zhang, who does public opinion monitoring, complained to me that the crawler script written in Python by their company could catch tens of thousands of news every day at the beginning, and then the whole IP segment was blacked out by the target website in less than three days. At this time, we should offer our killer app--Proxy IP Pool RotationThe

Let's take a real scenario: you want to capture the real-time newsletter of a financial website, and if you use the local IP to brush it, the server will immediately recognize the abnormal access. But if each request is changed to a "vest" (proxy IP), just like letting a different person to knock on the door to borrow newspapers, site administrators simply can not find the pattern. Here we have to boastDynamic Residential Proxy for ipipgoThey have millions of real residential IPs in their IP pool, which are automatically switched with each request, and are much more reliable than those server room IPs.

import requests
from itertools import cycle

 List of proxies provided by ipipgo (example)
proxy_pool = cycle([
    'http://user:pass@proxy1.ipipgo.com:8888',
    'http://user:pass@proxy2.ipipgo.com:8888', ...
     ... More ipipgo proxy nodes
])

url = 'https://目标新闻网站/news'

for page in range(1, 100):
    proxy = next(proxy_pool)
    try: response = requests.get(url, proxies={"http")
        response = requests.get(url, proxies={"http": proxy}, timeout=10)
         Processing web content...
    except Exception as e.
        print(f "Failed to access with {proxy}, automatically switching to the next IP.")

How many of the three major potholes in choosing a proxy IP have you stepped on?

There are all kinds of proxy services on the market, but 90% newbies fall into these pits:

As a special reminder, news sites' anti-crawls now detectGeographic location of the IP. For example, if you want to crawl the local news and access it like crazy with a foreign IP, a fool knows there is a problem. This is the time to use ipipgo'sCity-level location agentsThe IP of which city you want is directly selected, and with the randomized access interval, it's as real as a local user browsing.

Practical: using ipipgo to build intelligent collection system

Here to share a real case: an information aggregation platform with Scrapy framework + ipipgo agent, stable operation for more than half a year. Core configuration points:

1. Integrate ipipgo's API in the download middleware to automatically fetch fresh proxies
2. set upException Retry MechanismIf you encounter 403, change your IP address immediately.
3. Adjust the number of concurrency according to the characteristics of the site, the news category is recommended to control 5-10 concurrency

 Scrapy Middleware Configuration Example
class IpipgoProxyMiddleware.
    def process_request(self, request, spider).
        request.meta['proxy'] = 'http://动态获取的ipipgo代理地址'
         Automatically add request header artifacts
        request.headers['User-Agent'] = random.choice(pool of legitimate UAs)

Frequently Asked Questions You Might Ask

Q: Do I need to maintain my own agent pool?
A: No need at all! ipipgo's background will automatically eliminate invalid IPs, and can also be used according to your business needs.Intelligent recommendation of agent types. For example, if it detects that the target site has Cloudflare protection enabled, it will automatically switch the high stash proxy.

Q: What should I do if I encounter a CAPTCHA?
A: This is the ultimate anti-climbing kill. It is recommended to be combined with ipipgo'sLong-lasting session agents(a single IP to keep 30 minutes), and then combined with the use of coding platform. Of course the best way is to control the frequency of collection, don't push the site.

Q: Can overseas news sites be crawled?
A: Pay attention to comply with the laws and regulations of the target region. Technically speaking, ipipgo's global nodes cover 200+ countries and regions, and with the corresponding time zone settings and language request headers, there is no pressure to collect international news.

Say something from the heart.

Engaging in newsgathering this business, essentially in and website security team battle of wits. Last year, a customer used five proxy service providers at the same time, and finally ipipgo'shybrid proxy modelSaved him - mix data center agents with residential agents, and any tricky anti-climbing tactic will carry the day.

Finally, to remind the newbie friends: do not believe what "permanent free" proxy services, those are either fishing or IP pool filled with water.
