Twitter Media Crawler: Image and Video Capture Solution

A. Why your crawler is always blocked? May be missing this black technology

Twitter data collection old iron must have encountered this situation: just run a few minutes of the program, the account was restricted access. This thing is like a summer mosquito bite - although not fatal, but annoying thief. Many people's first reaction is to change the code logic, in fact, 80% of the problem lies in theNetwork Fingerprint ExposureUp.

Website wind control system is now very fine, the same IP frequent request is like a bald head of lice - obvious. Last time there is a friend who does the monitoring of the tide brand, with their own broadband connected to catch 3 hours, the result is that the entire IP segment has been pulled black, and even brush push are stuck into the PPT.

Second, how to choose a proxy IP is reliable? Remember these three lifeblood

There are a plethora of agency services on the market, but not many are suitable for media capture. Keep an eye on these three hard indicators when you're picking:

1. anonymity level: must choose high stash type (don't be greedy and use transparent proxy)
2. Survival time: dynamic IP recommended 5-15 minutes rotation
3. Geographic coverage: at least cover the mainstream areas of Europe, the United States, Japan and South Korea

Here's a little something for you.Dynamic Residential IP Pool for ipipgoHis IPs are all residential addresses at the level of real users. The actual test with his home IP capture video, continuous running 12 hours did not trigger the verification, than those server room IP is much more stable.

Third, hand to teach you to wear a cloak of invisibility to reptiles

Using Python's requests library as an example, configuring the proxy is a matter of three lines of code:

import requests

proxies = {
    'http': 'http://user:pass@gateway.ipipgo.io:9020',
    'https': 'http://user:pass@gateway.ipipgo.io:9020'
}

response = requests.get('https://twitter.com/xxx/media', proxies=proxies)

Be careful to putuserrespond in singingpassReplace it with the authentication information you get in the ipipgo backend. It is recommended to randomly pick IP nodes for each request, don't be available to one sheep.

IV. Wild tips for collecting program maintenance

Don't rest on your laurels even if you're using a proxy, these are a few tawdry operations that can extend the life of a crawler:

1. UA camouflage: Don't keep using Python's default UA, and get a whole lot of mainstream browser logos!
2. Behavioral simulation: Send requests at random intervals (0.5-3 seconds), not like a machine gun!
3. fail and try again: Cut the IP immediately when you encounter 403, don't fight it.

Recommended with ipipgo'sAutomatic link switchingFunctionality, set up an IP replacement strategy in the background, saves not a star and a half over manual management.

V. QA time for veteran drivers

Q: What can I do about slow proxy IPs?
A: Priority is given to service providers with local transit nodes. Like ipipgo has servers in Los Angeles and Tokyo, and the measured latency can be reduced to less than 200ms.

Q: What should I do if the video download is always interrupted?
A: large file transfer is recommended to use socks5 proxy, more stable than http proxy. ipipgo's s5 protocol supports direct go proxy download, pro-test 4K video without lag.

Q: How do I break the CAPTCHA when I encounter it?
A: Admit it when it's time to admit it. ipipgo offersReal Verification ServiceIt is much less time-consuming to write your own recognition model than to encounter a validation that is automatically transferred to manual processing.

Finally, to say a few words from the bottom of my heart, doing data collection is like fighting a guerrilla war, the key has to beHide well and run fast.. With a good proxy IP this magic weapon, with the reliable ipipgo service, basically in the compliance range to deal with most of the collection needs. What do not understand, directly to his official website to find online customer service nagging, faster than watching tutorials.
