Can you create a website in Python: a guide to building a website in Python

Hands-on with Python to build a website

Recently, a lot of people have been asking whether it's possible to make a serious website in Python. Let's get right to the conclusion:Not only can you do it, but you can do it with a twist.It's a good idea to use Python with a proxy IP service. Especially in the scenario where you need to handle a large number of network requests, using Python with a proxy IP service is a real treat!

Python site building three axes

Let's start by straightening out the three core components:

 Starting a service in 5 lines with the Flask framework
from flask import Flask
app = Flask(__name__)

@app.route('/')
def home(): @app.route('/')
    return "Master's website is open!"

Note a pitfall here:Don't use 80 for the default port., especially if you want to integrate proxy services. It is recommended to test with 5000 first and change it when you go live.

How do proxy IPs come in handy?

Take our ipipgo's user case, there is an e-commerce price comparison brother, using Python to write a price comparison site. The result was that the target site was blocked by the IP right after it was launched, and the problem was solved in this way:

import requests
from random import choice

 Proxy pool from ipipgo
proxies = [
    "203.34.56.78:8000",
    "120.77.181.92:3128",
    "47.98.132.21:8080"
]

res = requests.get(url, proxies={'http': choice(proxies)})

When this is done.Request Success Rate Spikes from 30% to 92%The key is that ipipgo's proxy pool is large enough to pick a random vest for each request. The key is that ipipgo's proxy pool is large enough to pick a random vest for each request, so the other party can't figure out the routine.

A practical guide to avoiding the pit

Name a couple of common fallouts for newbies:

1. Don't be lazy with timeout settingsProxy IP is not a god, set a timeout of 3 seconds to keep safe!
2. Intelligent retry mechanisms: Automatic IP change for 3 consecutive failures
3. Detailed logging: It's important to know which IPs work well and which ones always drop out.

QA time

Q: Why did you choose ipipgo's proxy?
A: three hard truths: fast IP pool update (hourly blood change), wide geographical coverage (200+ city nodes), guaranteed success rate (measured 95%+)

Q: How many visitors can a Python website resist?
A: Look at the architecture! Nginx reverse proxy + gunicorn, with ipipgo request distribution, daily activity of 100,000 + cases in our hands.

Q: What should I do if I encounter a CAPTCHA?
A: two combinations: ① use ipipgo's residential agent to reduce the probability of triggering ② docking coding platforms, don't be hard to just

Advanced Play

Here's a tip for old timers who are already on the road: try using theAsynchronous request + proxy poolThe combination of the aiohttp library with ipipgo's dynamic IP can more than triple the speed. The code looks like this:

import aiohttp
import asyncio

async def fetch(url).
    async with aiohttp.ClientSession() as session: async with session.get(url, proxy="") as resp.
        async with session.get(url, proxy="http://ipipgo-proxy.com:8000") as resp.
            return await resp.text()

Note that ipipgo's dedicated access point is used here, which is more robust than a single IP. This option is particularly suitable forAnalytical websites that require a data sweeping frenzy, who uses it.

Let's end on a positive note.

Python build this thing, say difficult, say simple is not simple. The key must beFind the right tool for the jobThe first thing you need to do is to get a good deal on the proxy IP. Proxy IP this piece of direct copy of homework to choose ipipgo on the end, people specializing in this, a variety of abnormalities have given you full consideration. Don't blindly toss yourself, there are ready-made wheels do not use is a fool.

If there is still confusion after reading, go directly to the official website of ipipgo to pull the document, customer service 24 hours online. Remember.Fear of half-assed projectsIf you want to use the service, don't take it on the chin, you won't have enough money to buy regrettable pills.
