Hands-on Google woolgathering with Python
Engaged in data collection of the old iron know, want to use Python to directly grab Google search results like a basket of water - a waste of effort. Google's anti-climbing mechanism is stricter than the cell access control, there is no special means simply can not get. Today we will nag how to use the proxy IP this magic weapon, with Python easily take the search results.
Why do I need a proxy IP as a bodyguard?
To give a chestnut, you take your own IP wild brush Google, like in the supermarket even ate 20 free trial sausage, the security guards do not stare at you to stare at who? Google's anti-climbing system will:
1. Directly put a seal on your IP (blocking)
2. Popping CAPTCHA to disgust you
3. Returning false data to fool you
This is where proxy IPs are needed as stand-ins.ipipgo's Residential Dynamic IP PoolIt's like giving each request a new vest so that Google thinks a different user is operating on each visit.
Preparation for the start-up
First install these two essential libraries
pip install requests-html pandas
This is the recommended configuration
Proxy type = {
"protocol": "http",
"address": "ipipgo Dynamic Residential Pool",
"Authentication method": "username+password"
}
Focusing on the proxy settings, use theipipgo's API to get dynamic IPsWhen you do, remember to turn on theautomatic switchingFunction. It's like fighting a guerrilla war, where each request changes to a different position, and the anti-climbing system simply can't figure out the pattern.
Real-world code disassembly
from requests_html import HTMLSession
def grab google keyword(keyword): session = HTMLSession()
session = HTMLSession()
Get the latest proxy from ipipgo
proxyConfig = {
"http": "http://用户名:密码@gateway.ipipgo.cc:端口",
"https": "http://用户名:密码@gateway.ipipgo.cc:端口"
}
try.
Response = session.get(
f "https://www.google.com/search?q={keyword}",
headers={"User-Agent": "Mozilla/5.0 (Windows NT 10.0).
headers={"User-Agent": "Mozilla/5.0 (Windows NT 10.0)..."}
)
response.html.render(timeout=20)
Position the search results block
results list = response.html.xpath('//div[@class="tF2Cxc"]')
return [results.text for results in results list]
except Exception as e.
print(f "Rollover: {str(e)}")
Automatically switching IP's in a rotating operation
ipipgo.rotate_ip()
A guide to avoiding the pit:
1. Don't be too hasty in the request interval, it is recommended to set a random delay of 2-5 seconds.
2. User-Agent should be installed like a normal browser
3. Don't fight hard when encountering CAPTCHA, immediately change ipipgo's new IP.
Common Rollover Scene QA
| Symptoms of the problem | method settle an issue |
|---|---|
| Returns a blank result | Check if XPath is out of date, use ipipgo's browser debugging feature |
| The connection keeps timing out. | Switching proxy protocols (http/https alternately) |
| Suddenly, I'm not receiving data. | Add ipipgo's automatic IP refresh mechanism to the code |
Soul torture:
Q: Can I build my own agent pool?
A: Unless you want to experience the joy of being an operations engineer, go straight to theipipgo ready serviceIt's more economical, their IP pool is updated daily with 8 million + residential IPs, much more reliable than tossing it yourself.
Q: How much does it cost?
A: ipipgo has pay-as-you-go packages such as39 for 10G of trafficThis kind, cheaper than Starbucks monthly card. The point is that their IP survival rate can go up to 95%, unlike some pheasant service providers who pimp people with junk IPs.
Closing out the show.
Finally, an advanced tip: Split the collection task into multiple sub-tasks, using theMultiple geographic IPs for ipipgoSimultaneously open to engage. For example, if you want to collect search results from different regions, you can collect them at the same time with the IPs of the United States, Japan and Germany, and the efficiency will be tripled directly.
Remember the core essentials:
1. Quality of representation makes the difference
2. The request parameters should be in the form of a real person
3. Exception handling is essential
According to this set of rules to engage in, the collection of Google search results is like playing. If there is anything you do not understand, go directly to the official website of ipipgo to find their technical small brother, the speed of reply is faster than the delivery boy to deliver food.
