Proxy Server Address Format: Proxy Address Format Specification Note

What does a proxy address really look like?

Many people are confused when they first see an agent's address, which is actually structured similarly to a courier slip number. The standard format isProtocol Type://IP Address:Port. Give me a chestnut:socks5://114.55.66.77:8080Here socks5 is the transport protocol, and the four numbers following the colon are the port numbers.

Pay attention to these three key points: 1. protocol type must be lowercase (http/https/socks5) 2. IP address can not be with spaces 3. port number must be a number between 0-65535. Just like sending a courier to fill in the wrong address will be sent to the wrong place, the format is not right proxy pressure can not connect.

The most common pitfalls for white people to step into

Recently, when helping users troubleshoot their problems, I found that 80%'s connection failures are all formatting problems:

 Bug case: Missing protocol header
127.0.0.1:8080 Missing http://
 The correct way to write
http://127.0.0.1:8080

There's also the tart operation of writing the port after the authentication information:http://user:pass:8080@1.2.3.4(The correct term should behttp://user:pass@1.2.3.4:8080). This error is like writing a cell phone number as an ID number, which the system doesn't even recognize.

Hands-on value assignment tutorial

Take the Python crawler for example, set it up like this with ipipgo's proxy:

import requests
proxies = {
    'http': 'http://用户名:密码@proxy.ipipgo.net:24000',
    'https': 'http://用户名:密码@proxy.ipipgo.net:24000'
}
response = requests.get('http://example.com', proxies=proxies)

Watch this space.The username and password should be preceded by the @ symbol, where many veteran drivers roll over. If you are using a dynamic residential IP, remember to get a new address via the API before each request.

QA First Aid Kit

Q: Can I write any port number?
A: It depends on which ports the proxy service provider has opened, like ipipgo's default ports are 24000-25000, ports that are not in this range will fail to connect.

Q: What about IPv6 addresses?
A: It must be enclosed in square brackets, such assocks5://[2001:db8::1]:1080This is an internationally recognized format.

Q: What if I need both account password and IP whitelisting?
A: This situation should contact customer service to open double verification, ipipgo's enterprise version supports this kind of tawdry operations

Why ipipgo?

Having tested more than a dozen service providers, I ended up locking in on ipipgo for three main reasons:

1. Full protocol support (especially socks5 protocol is crawler friendly)
2. Transparent prices with no hidden pits (starting at $7.67/G for dynamic homes, which is cheaper than buying milk tea)
3. Client comes with format detection (wrong address will be alerted immediately by a pop-up window)

theirStatic Residential IPIt is especially suitable for businesses that require a fixed address, such as cross-border e-commerce store management. Previously, there is a friend of independent station, with 35 yuan / month package to solve the PayPal wind control problem, than to buy a stand-alone server cost-effective.

And finally, a cold one: the double slash in the proxy address//It can actually be omitted, likehttp:114.55.66.77:8080It will also work. But for compatibility considerations, it is still recommended to write the full format honestly. It's like wearing a suit and buttoning it up, it's the details that make it look professional, isn't it?
