python implementation of ip proxy: using Python to build proxy service program

First, Python play proxy IP in the end what is the use?

The old iron engaged in crawlers certainly understand that sometimes the target site to prevent strict, with their own real IP minutes to be blocked. This time you need a proxy IP tocover upIt's like playing hide-and-seek and constantly changing hiding places. For example, to do e-commerce price monitoring, the same IP frequent requests will be blacked out, with Python + proxy IP can simulate real users in different regions.

Let's take a real example: a company wants to test the loading speed of its website across the country, and manually cutting IPs is exhausting. With Python scripts and proxy pools, it takes 20 minutes to automatically run the access test for 30 provinces, and the data is directly generated into visualized charts.

Second, hand to teach you to build agent services

first of allKey misconceptions: Many people think they have to set up their own servers to do proxy, in fact, completely unnecessary. Like ipipgo such professional service providers have done a good job of ready-made resource pool, we directly use the API to call on it. The following code demonstrates how to use the requests library to go proxy:

import requests

 Proxy information from ipipgo (remember to replace your account)
proxy_api = "https://api.ipipgo.com/get?key=你的密钥"

 Get the proxy IP
ip_data = requests.get(proxy_api).json()
proxy = {
    'http': f "http://{ip_data['ip']}:{ip_data['port']}",
    'https': f "http://{ip_data['ip']}:{ip_data['port']}"
}

 Visit the target site with a proxy
response = requests.get("https://目标网站.com", proxies=proxy)
print(response.text)

Look at line 7 of thef-string formatting, which is Python 3.6+ syntax. Some old tutorials are still formatted in %, that writing style is long outdated. It is recommended to use the new syntax, the code is more refreshing.

Third, to avoid the use of the agent of those pits

Three common mistakes newbies make:

Here's a shout out to ipipgo'sIntelligent SwitchingTheir API returns IPs with parameters such as geography and operator, which is especially suitable for scenarios that require precise positioning. For example, if you are doing local life service, you need to use the residential IP of the corresponding city to make it look real.

Fourth, how to choose enterprise-level solutions?

It is important to choose a package based on the size of your business:

• Individual small projects: The standard version of Dynamic Residential is good enough to run tens of thousands of requests for over $7 for 1G of traffic
• TeamworkDynamic IP: enterprise version of dynamic IP, support for multiple concurrent users and more pure IP library
• Long-term fixed requirements: buy a static residential IP directly, 35 bucks a month to build whatever you want!

Previously, there is an overseas questionnaire research customers, began to use the free agent greedy cheap, the result of poor data quality by the party scolded. After switching to ipipgo's cross-border line, the success rate soared from 37% to 89%, which is worth the money.

V. Frequently Asked Questions QA

Q: Do I have to maintain the proxy IP myself?
A: If you use ipipgo, you don't need to use it at all. Their IP pool is automatically updated every day to eliminate invalid IPs, which is much more trouble-free than raising your own.

Q: What if I need both socks5 and http proxy?
A: Their background can be set up to convert protocols, the same IP support multiple protocols to access, do not have to repeat the purchase.

Q: Will I be disconnected if I use too much traffic?
A: No, ipipgo's packages are allflexible billingIf you do not use the actual amount, you will have to pay the difference in price, so as to avoid any sudden interruption of business.

Lastly, don't just look at the price of the proxy service, IP purity and after-sales service is the key. Some cheap packages look cost-effective, the actual use of all the IP has been invalidated, but delayed. Like ipipgo this dare to put the price of transparent hanging official website, at least use with peace of mind.
