ip proxy how to realize: analysis of proxy IP working principle and configuration core

First, proxy IP in the end is what the hell?

Let's take an example, if you write your house number directly when you fill in the address when you buy online, can the courier find you directly? Proxy IPs are like specialized IPs that help youStagecoach for courier deliveryWhen you are surfing on the Internet, the proxy server will receive the website data for you and then transfer the "delivery" to you. When you surf on the Internet, the proxy server will first receive the website data for you, and then transfer the "express" to you, so that the other party sees only the address of the station (proxy IP) rather than your real location.

There are three main types of agents on the market:

Secondly, how does this stuff make a web request change its face?

To put it bluntly.The "nested" request process: When you type a URL into your browser, the request will first take a detour to a proxy server, which will use its own IP to access the target site, get the data and then send it back to you. The whole process is just like when you ask your friend to help you buy something at the supermarket, and the cashier only remembers your friend's face.

Here's a live code example in Python:

import requests

proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:9020',
    'https': 'http://username:password@gateway.ipipgo.com:9020'
}

response = requests.get('http://example.com', proxies=proxies)
print(response.text)

Note that you have to replace username and password with your own authentication information obtained from the ipipgo platform, and the port number may change depending on the type of package.

Third, hand to teach you to match the value of the agent environment

Here are a few points where white people tend to fall head over heels:

1. In the ipipgo client settingsRemember to turn on protocol encryptionOtherwise, it's like sending a courier without a receipt.
2. Dynamic residential users should enable the IP rotation function, it is recommended to set up 15-30 minutes automatic switching
3. Encounter connection failure first check the whitelist settings, many platforms need to bind the local IP in advance

It is recommended to use this test command to see if the proxy is in effect:

curl http://ip.ipipgo.com --proxy http://username:password@gateway.ipipgo.com:9020

Fourth, package selection difficulties see here

Right-sized according to business needs:

• Regular users swipe the page:Dynamic residential (standard)More than enough for the $7.67/GB cabbage price
• Enterprise-class data collection: optionalDynamic Residential (Business), $9.47/GB with exclusive access
• Long-term fixed IP required: directly onStatic homes35/IP for a full month.

Recently, I discovered a new trick: to combine dynamic and static packages.mixThe following are some examples of how to do this. For example, use a dynamic IP for data capture, and cut key operations to a static IP, which saves money and is safe.

v. guide to demining common problems

Q: Why does the Internet slow down when I use a proxy?
A: 80% of the nodes are not selected correctly, ipipgo's client comes with intelligent routing function, select "auto-match" than manually select much faster!

Q: What should I do if my IP is always blocked?
A: Don't use a free proxy! ipipgo's TK line is specialized in solving this problem, the success rate can reach 95% or more!

Q: Does the cell phone work?
A: Android and iOS have a special APP, just open the global proxy in the settings, it's almost as simple as connecting to WiFi.

VI. Don't step on these potholes

1. Don't be on the same IPdo the same thing over and over againThe site is not stupid.
2. Don't use dynamic IP to log in important accounts, be careful of being taken as a pirate.
3. Overseas business remember to choose the node corresponding to the region, ipipgo has 200+ countries to choose from!

As a final rant, proxy IPs are like the Internet world'scloak of invisibilityThe key is to choose the right service provider, like ipipgo, which can provide 1v1 customized program. The key is to choose the right service provider, like ipipgo can provide 1v1 customized program, especially suitable for special needs of the old iron. Their cross-border line I tested, the delay is lower than similar products at least 30ms, do overseas business is truly recommended to try.
