U Treasure Proxy Shop

Data parsing in most cases refers to the collection of technical or other information. For example, a local proxy server can be used for parsing "log data". That is, information about the work of the site, the application, which in the future will be useful for developers to find and fix various bugs.

On smartphones, when a proxy is turned on, the corresponding indicator (the "VPN" icon) appears in the status bar. In Windows you have to go to "Settings", open "Network and Internet". Under "Proxy Server", if the item "Manual" is activated, it means that the proxy is engaged right now.

It is a proxy that everyone can connect to. That is, it handles absolutely all requests without interacting with the traffic in any way, without monitoring its packets.

To scrape all HTML content from a website using Scrapy, you need to create a spider that visits each page of the website and extracts the HTML content. Here's a simple example:

Create a Scrapy Project:
If you haven't already, create a Scrapy project by running the following commands in your terminal or command prompt:

scrapy startproject myproject
cd myproject

Define a Spider:
Open the spiders directory in your project and create a spider (e.g., html_spider.py). Edit the spider file with the following content:

import scrapy

class HtmlSpider(scrapy.Spider):
    name = 'html_spider'
    start_urls = ['http://example.com']  # Start with the main page of the website

    def parse(self, response):
        # Extract HTML content and yield it
        html_content = response.text
        yield {
            'url': response.url,
            'html_content': html_content
        }

        # Follow links to other pages (if needed)
        for next_page_url in response.css('a::attr(href)').extract():
            yield scrapy.Request(url=next_page_url, callback=self.parse)

This spider, named html_spider, starts with the main page (start_urls) and extracts the HTML content. It then follows links (a::attr(href)) to other pages and extracts their HTML content as well.

Run the Spider:
Run your spider using the following command:

scrapy crawl html_spider -o output.json

This command will execute the html_spider and save the output in a JSON file named output.json. Each item in the JSON file will contain the URL and HTML content of a page.

The main scenarios for using a proxy server: bypassing blocking, hiding the real IP, protection of confidential data when connecting to public WiFi access points, interaction with blocked applications, connection to closed portals, forums (which operate only in one country, region).
