http online proxy: online HTTP proxy site usage and security guidelines

Teach you to play with online HTTP proxies!

Recently, a lot of friends asked me what to do with the web page can not be opened, data collection always failed, in fact, with the right tool can be solved. Today with the gang nagging this online HTTP proxy in the end how to use, incidentally, how to avoid stepping on the pit. We do not organize those false head of the brain, directly on the dry goods.

First, what is the HTTP proxy? Why use it?

Simply put, it's a middleman that helps you to relay Internet requests. For example, if you are in Beijing and want to visit a website in Shanghai, you can make a detour through a proxy server and the other party will think you are a Shanghai user. This feature is particularly suitable for business scenarios that require a large number of access to the web, such as e-commerce price comparison, data crawling these.

However, the proxy services on the market are uneven, and some free proxies will steal user data. So you have to keep your eyes open when choosing a service provider, and we will teach you how to recognize the reliable ones later.

Second, the online agent practical operation manual

Take ipipgo as an example, the interface of his family is more refreshing. After registering and recharging your account, you will find the "Generate Proxy Link" function in the console. Here's a tip: chooseStatic Residential IPSuitable for scenarios that require long-term stable connections, dynamic IP is more suitable for frequent switching needs.

 Python Examples
import requests

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

response = requests.get('destination URL', proxies=proxies)
print(response.text)

Be careful to replace the username, password and port in the code, these information can be found in the console. If you encounter a connection timeout, check if you have entered the wrong proxy address.

III. Safe use of the three axes

1. Don't use the default password.Change your password as soon as you get the proxy account, don't use a weak password like 123456!
2. Choose the right encryption protocol: Prioritize the transmission of sensitive data using the HTTPS protocol
3. Dosage monitoring cannot be understated: Set up traffic alerts in the background, don't wait until you're overloaded!

Why do you recommend ipipgo?

After using seven or eight proxy service providers, I ended up using ipipgo for a long time for three main reasons:
1. The IP pool is large enoughHis family has local IPs from more than 200 countries, and friends who do cross-border e-commerce use them and say they are stable!
2. Price transparency: Dynamic Residential is a minimum of $7+ for 1 G, which is a much better deal than some per-minute billing
3. Fast technical support: The last time I had a technical problem, customer service fixed it in 10 minutes!

Newbies are advised to buy the Dynamic Residential Standard Edition to try the water first, and go directly to the Enterprise Edition if you have a large amount of business. They also recently came out with a TK special line, which can be of interest to those who do short videos overseas.
