To speed up scraping by leveraging asynchronous programming in Python, you can use the asyncio library along with asynchronous HTTP requests. The aiohttp library is commonly used for asynchronous HTTP requests. Here's a basic example to help you get started:

Install Required Packages:

pip install aiohttp

Asynchronous Scraping Script:

import asyncio
import aiohttp

async def scrape_url(session, url):
    try:
        async with session.get(url) as response:
            if response.status == 200:
                content = await response.text()
                # Process the content as needed
                print(f"Scraped {url}: {len(content)} characters")
            else:
                print(f"Failed to scrape {url}. Status code: {response.status}")
    except Exception as e:
        print(f"Error scraping {url}: {str(e)}")

async def main():
    urls_to_scrape = [
        'https://example.com/page1',
        'https://example.com/page2',
        # Add more URLs as needed
    ]

    async with aiohttp.ClientSession() as session:
        tasks = [scrape_url(session, url) for url in urls_to_scrape]
        await asyncio.gather(*tasks)

if __name__ == "__main__":
    asyncio.run(main())

• • This script defines an asynchronous function scrape_url to perform the scraping for a given URL.
  • The main function creates an asynchronous HTTP session using aiohttp.ClientSession and gathers the scraping tasks.
  • The asyncio.run(main()) line runs the main asynchronous function.

• Running the Script:

python your_scraper_script.py

This example demonstrates the basics of asynchronous scraping. Asynchronous programming can significantly speed up scraping tasks, especially when making multiple concurrent HTTP requests.

Keep in mind that not all websites support asynchronous scraping, and some may have restrictions or rate limiting. Always adhere to the website's terms of service, and consider adding delays between requests to avoid overloading the server.

To run GUI autotests in GitLab CI\CD using Docker, Selenium, and PyTest, you can follow these steps:

1. Create a .gitlab-ci.yml file in the root directory of your project. This file will define the pipeline and the jobs for your CI\CD process.

2. Configure the pipeline to use the appropriate image for your tests. In this case, you can use a Python image with the required dependencies installed.

3. Define the before_script section to set up the environment for the tests, including installing the necessary packages and downloading the required drivers for Selenium.

4. Define the test job to run the PyTest tests using the Selenium WebDriver.

Here's an example of a .gitlab-ci.yml file:

stages:
  - test

variables:
  SELENIUM_CHROME_DRIVER: '102.0.5005.62'
  SELENIUM_FIREFOX_DRIVER: '0.26.0'

image: python:3.8

cache:
  paths:
    - .venv
    - requirements.txt

before_script:
  - apt-get update -qq
  - apt-get install -y --no-install-recommends \
      build-essential \
      wget \
      xvfb \
      xvfb-run
  - pip install --upgrade pip
  - pip install --quiet --upgrade pytest
  - pip install --quiet selenium
  - pip install --quiet webdriver-manager
  - wget https://github.com/SeleniumHQ/selenium/releases/download/v${SELENIUM_CHROME_DRIVER}/chromedriver_linux64.zip
  - unzip chromedriver_linux64.zip chromedriver
  - wget https://github.com/SeleniumHQ/selenium/releases/download/v${SELENIUM_FIREFOX_DRIVER}/geckodriver-v${SELENIUM_FIREFOX_DRIVER}
  - mv geckodriver-v${SELENIUM_FIREFOX_DRIVER} geckodriver

test:
  stage: test
  script:
    - pytest tests/
  tags:
    - selenium
  artifacts:
    reports:
      - html
  only:
    - master
    - merge_requests

This .gitlab-ci.yml file defines a single stage called test that runs the PyTest tests in the tests/ directory. The before_script section installs the necessary dependencies, downloads the Selenium WebDriver for Chrome and Firefox, and sets up the environment for running the tests.

The tags: - selenium line ensures that the job runs on a runner with the selenium tag, which should have the appropriate Selenium WebDriver installed. The artifacts: reports: - html line enables the generation of HTML reports for the test results.

The only: - master - merge_requests line specifies that the tests should be run on every commit to the master branch and on every merge request.

Once you've set up the .gitlab-ci.yml file, commit and push it to your repository. Then, create a new merge request or push to the master branch to trigger the CI\CD pipeline and run the GUI autotests using Docker, Selenium, and PyTest.

Most often it is used on the iPhone just to bypass the blocking of access to certain resources. But also VPN is one of the most effective methods of protecting your confidential information. After all, with VPN all traffic is additionally encrypted, the provider can't read it even if it's intercepted.

There are special online services that use IP and HTTP connection tags to determine if a proxy is being used from your equipment. The most popular are Proxy Checker, Socproxy.

It depends on which browser you are using. In Opera, Chrome, Edge a proxy is configured at the level of the operating system itself. In Firefox in the settings there is a special item (in the "Privacy" section).
