News Data Gathering: Real-time Media Monitoring System

How hard is this news data collection thing?

Real-time media monitoring brothers understand, want to stare at the major sites 24 hours to catch the news, just like playing cat and mouse. Two days ago, a good crawler program, the next day was the site blocked IP blocked mom do not recognize. Especially when it comes to emergencies, the anti-climbing mechanism of each media website is just like playing chicken blood, and ordinary IPs can't carry three rounds at all.

To cite a real case: a financial team wants to monitor the announcement of listed companies, the result is that the fixed IP continuous access to less than 2 hours, directly mention 403 error. Later, it switched toDynamic Residential Proxy for ipipgo, spreading the requests to exit IPs in different regions, which is considered to catch the data steadily.

How did proxy IPs become a lifesaver?

To put it bluntly.fight a guerrilla war. Website blocking IP mainly depends on two points: access frequency and request characteristics. If you use a proxy IP:

 Ordinary request (high risk)
for i in range(100).
    requests.get("news site")

 Use ipipgo proxy (solid as an old dog)
proxy = {"http": "http://用户名:密码@gateway.ipipgo.com:9020"}
for i in range(100):
    requests.get("news site", proxies=proxy, timeout=3)

The key is toRandom IP address switchingipipgo's proxy pool has 20 million+ residential IPs, which automatically change IPs with each request, so websites simply can't figure out the pattern. Moreover, their IPs are residential addresses used by real people to access the Internet, which is more than one level more reliable than server room IPs.

Three Tips to Build a Surveillance System

1. IP Rotation StrategyDon't be stupid and cut IPs in order, you need to get randomized mode. ipipgo's API returns a list of available IPs, so it is recommended to randomly pick a new IP every 5-10 requests.

2. The requesting head has to be able to do tricks. Instead of using the same User-Agent, prepare a dozen or so commonly used browser logos and randomly select one for each request.

3. Anomalies must be handled with forethought. Don't panic when it comes to CAPTCHA, use ipipgo'sExclusive IP packageWork with a coding platform that specializes in hard-to-chew websites

QA time (a must for newbies)

Q: Why do I have to use a paid proxy? Don't the free ones smell good?
A: free agent nine out of ten is the pit! Either the speed is slow to doubt life, or early by the major sites to pull the blacklist. ipipgo's new IP survival rate to 98%, this is the professional tool should have the appearance of!

Q: How to judge the proxy IP quality?
A: Remember three indicators: response speed (don't exceed 3 seconds), anonymity level (must be high stash), availability (below 95% direct pass). These parameters can be seen in real time in the background of ipipgo!

Q: What should I do if I encounter a particularly severe anti-climb?
A: On the stunt -Customized geographic IP for ipipgo. For example, if you want to catch local news, use the residential IP of the local city and visit it with the normal work and rest time, the website can't tell if it's a real person or a crawler!
