Scraping without libraries in Python typically involves making HTTP requests, parsing HTML (or other markup languages), and extracting data using basic string manipulation or regular expressions. However, it's important to note that using established libraries like requests for making HTTP requests and BeautifulSoup or lxml for parsing HTML is generally recommended due to their ease of use, reliability, and built-in features.

Here's a simple example of scraping without libraries, where we use Python's built-in urllib for making an HTTP request and then perform basic string manipulation to extract data. In this example, we'll scrape the title of a website:

import urllib.request

def scrape_website(url):
    try:
        # Make an HTTP request
        response = urllib.request.urlopen(url)
        
        # Read the HTML content
        html_content = response.read().decode('utf-8')

        # Extract the title using string manipulation
        title_start = html_content.find('', title_start)
        title = html_content[title_start:title_end].strip()

        return title
    except Exception as e:
        print(f"Error: {e}")
        return None

# Replace 'https://example.com' with the URL you want to scrape
url_to_scrape = 'https://example.com'
scraped_title = scrape_website(url_to_scrape)

if scraped_title:
    print(f"Scraped title: {scraped_title}")
else:
    print("Scraping failed.")

Keep in mind that scraping without libraries can quickly become complex as you need to handle various aspects such as handling redirects, managing cookies, dealing with different encodings, and more. Libraries like requests and BeautifulSoup abstract away many of these complexities and provide a more robust solution.

Using established libraries is generally recommended for web scraping due to the potential pitfalls and challenges involved in handling various edge cases on the web. Always ensure that your scraping activities comply with the website's terms of service and legal requirements.

If you're working with Spring Boot in Java and need to parse JSON with multiple attachments, you might be dealing with a scenario involving HTTP requests with JSON payload and file attachments. In this case, you can use @RequestPart in your controller method to handle JSON and multipart requests.

Here's a basic example

Create a DTO (Data Transfer Object) class:

public class RequestDto {
    private String jsonData;
    private MultipartFile file1;
    private MultipartFile file2;

    // getters and setters
}

Create a controller with a method to handle the request:

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestPart;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

@RestController
@RequestMapping("/api")
public class ApiController {

    @PostMapping("/processRequest")
    public ResponseEntity processRequest(@RequestPart("requestDto") RequestDto requestDto,
                                                @RequestPart("file1") MultipartFile file1,
                                                @RequestPart("file2") MultipartFile file2) {
        // Process JSON data in requestDto and handle file attachments
        // ...

        return ResponseEntity.ok("Request processed successfully");
    }
}

3. Send a multipart request with JSON and attachments:

Using tools like Postman or curl, you can send a multipart request. Here's an example using Postman:

• Set the request type to POST.
• Set the URL to http://localhost:8080/api/processRequest.
• Under the "Body" tab, select "form-data".
• Add three key-value pairs:
  • Key: requestDto, Value: {"jsonData": "your_json_data"}
  • Key: file1, Value: select a file
  • Key: file2, Value: select another file

Make sure you have the appropriate dependencies in your project for handling multipart requests. If you're using Maven, you can include the following dependency in your pom.xml:

    org.springframework.boot
    spring-boot-starter-web

Adjust the example based on your specific use case and the structure of your JSON data. The key point is to use @RequestPart to handle both JSON and file attachments in the same request.

Proxy configuration on an iPhone refers to the process of setting up a proxy server to route your internet traffic through the proxy server. This can be useful for various reasons, such as improving security, privacy, or accessing content that may be restricted in your location.

To set up a proxy on your iPhone, follow these steps:

1. Open the "Settings" app on your iPhone.
2. Scroll down and tap on "Wi-Fi."
3. Ensure that you are connected to the Wi-Fi network for which you want to set up the proxy. If not, connect to the desired network.
4. Tap on the blue "i" next to the connected Wi-Fi network.
5. Scroll down to the "HTTP Proxy" section.
6. To enable the proxy, tap on the "Automatic" option and select "Manual."
7. Enter the proxy server address (IP address or hostname) in the "Server" field.
8. Enter the port number in the "Port" field.
9. If your proxy server requires a username and password, enter them in the "Username" and "Password" fields.
10. If your proxy server uses a different protocol (e.g., SOCKS), select the appropriate protocol from the "Proxy Server" dropdown menu.
11. Tap on "Wi-Fi" in the top left corner to save your changes and exit the settings.

After completing these steps, your iPhone will use the configured proxy server to route your internet traffic. Keep in mind that not all apps may respect the proxy settings, and some may require additional configuration or use a built-in VPN feature.

Technically, the ISP cannot block all VPN servers. But it is possible to block some of them. In this case, you can use any other VPN service. But you have to be careful with "free" ones, as they often make money from collecting and selling users' confidential data.

Chromium does not support proxies in-house. There is a corresponding item in the menu, but clicking on it will open the regular proxy server settings in Windows or MacOS.
