HTTP Crawler Proxy Pool: Real-time Monitoring and Opinion Analysis of Hot Topics in Zhihu/Weibo

Can't handle the backcrawl? Try this wild trick.

Recently, some friends who do public opinion monitoring complained to me that the protection of Weibo and Zhihu is getting stricter and stricter now. Just grabbing a few topic data will be blocked IP, and real-time monitoring is like playing a cat and mouse game. In fact, the key is to learn how to "fight guerrilla warfare" - use proxy IP pools to collect data by switching horse armor in turn, just as theSend in an intelligence team instead of going it alone.The

For example, in the recent incident of a star collapsing a house, the first 15 minutes of microblogging topic data changes particularly fast. If you use a fixed IP to catch, it won't last more than half an hour and will be blacked out. At this time, if you use dynamic residential IP rotation, each request is changed to a real home network address, the platform's anti-climbing system simply can not distinguish between real people visit or machine collection.

Choosing the right tool is more important than effort

This is a must.Residential agent pool for ipipgo. Their IP pool is really big, more than 90 million home network addresses can be adjusted at will. I've tried using their API interface before, and it's as easy as ordering takeout and choosing an address to retrieve an IP. The best thing is that it supports all protocols, no matter whether you use the requests library or the scrapy framework, it can be seamlessly connected.

I'll teach you how to build an intelligence network.

Here's a guide to do exactly that (in Python, for example):

1. first go to ipipgo to get an API key, remember to select theChinese Residential IP Pool

2. In the code to write an IP scheduler, it is recommended to set every 5-10 requests automatically change IP

3. Remember to bring the latest version of Chrome UA in the masquerade request header.

4. Here comes the kicker! SetupRandomized delay mechanismDon't be a robot and grab the data on time.

The last time I helped a PR company to build a monitoring system, I used this method to run for 72 hours without turning over. The key is to simulate real user behavior, do not let the platform to find patterns. Just like you go to the supermarket to buy food, will not be fixed every 5 minutes to take a piece of goods, right?

Old Driver's Guide to Avoiding Pitfalls

Q: Why do I still get blocked even if I use a proxy IP?

A: 80% of the IP quality is not good. The IP of the server room on the market has long been labeled by the platform, you have to use a real - residential IP like ipipgo, from real home broadband to be reliable.

Q: How many IPs do I need to prepare to be enough?

A: Look at the monitoring frequency. It is generally recommended to prepare 5-10 IPs to do the rotation pool, like ipipgo's pool is large enough, there is no fear of IP being drained.

Q: How to choose between dynamic and static IP?

A: Grab hotspots with dynamic, long-term tracking with static. ipipgo supports both, but also can be mixed and matched as needed.

Real-world case study: monitoring the star collapsed house incident

Last year a top stream rollover event, we used ipipgo's proxy pool to do the whole monitoring. The key operation has 3 steps:

1. Dynamic IP rotation crawl microblogging real-time topic data

2. static IP continuous monitoring know-how in-depth discussion

3. Analyzing the diffusion path of public opinion by geographical IP distribution

As a result, we found the public opinion inflection point 40 minutes earlier than our competitors, and helped our client to seize the golden time for public relations. This operation directly renewed the client's monitoring service for three years, which means that choosing the right tool can really save your life.

Finally, to be honest, doing public opinion monitoring now is like dancing on a tightrope. It's important to get the data right and to ensure stability. Instead of tossing your own IP blocked, why not find a reliable proxy service provider. ipipgo such professional players to provide a solution, than their own blind mess much more worrying.
