4G Proxy ProxyEmpire

Open the control panel of your computer, find and select the item "Network connection", and then click "Show network connections", "Local network connections" and "Properties". If there is a tick next to "Obtain an IP address automatically", then no dedicated proxy has been used. If you see numbers there, it will be your address.

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.

ProxyMaster is designed to help users manage and automate the process of using multiple proxy servers, making it easier to rotate through proxies and maintain a stable connection.

ProxyMaster offers features such as:

1. Proxy rotation: Automatically switch between a list of proxy servers to maintain a stable connection.

2. Proxy testing: Test the speed and reliability of each proxy server in your list.

3. Browser integration: Integrate with popular web browsers like Chrome, Firefox, and Internet Explorer.

4. Scheduler: Schedule proxy rotation and testing tasks to run at specific times or intervals.

5. Logging: Keep a record of your proxy usage and any errors or issues encountered.

To keep only unique external links while scraping with Scrapy, you can use a set to track the visited external links and filter out duplicates. Here's an example spider that demonstrates how to achieve this:

import scrapy
from urllib.parse import urlparse, urljoin

class UniqueLinksSpider(scrapy.Spider):
    name = 'unique_links'
    start_urls = ['http://example.com']  # Replace with the starting URL of your choice
    visited_external_links = set()

    def parse(self, response):
        # Extract all links from the current page
        all_links = response.css('a::attr(href)').extract()

        for link in all_links:
            full_url = urljoin(response.url, link)

            # Check if the link is external
            if urlparse(full_url).netloc != urlparse(response.url).netloc:
                # Check if it's a unique external link
                if full_url not in self.visited_external_links:
                    # Add the link to the set of visited external links
                    self.visited_external_links.add(full_url)

                    # Yield the link or process it further
                    yield {
                        'external_link': full_url
                    }

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

- visited_external_links is a class variable that keeps track of the unique external links across all instances of the spider.
- The parse method extracts all links from the current page.
- For each link, it checks if it is an external link by comparing the netloc (domain) of the current page and the link.
- If the link is external, it checks if it is unique by looking at the visited_external_links set.
- If the link is unique, it is added to the set, and the spider yields the link or processes it further.
- The spider then follows links to other pages, recursively calling the parse method.

Remember to replace the start_urls with the URL from which you want to start scraping.

You need to go to "Settings", click on "WiFi", select the current network to which the smartphone is connected, tap on "Proxy settings". And then - deactivate the item.
