Impromptu Proxy Server

To disable a proxy-server in Yandex browser, you need to do the following steps:

Open the browser. Click on the icon "?" in the upper right corner. Go to "Settings". Type "proxy" in the search box. Click on "Proxy settings". In the tab that opens, select "Network settings". Disable the "Use proxy server" option.

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.

In WCF (Windows Communication Foundation), UDP communication is not supported directly as it is a point-to-point communication protocol. However, you can create a custom UDP duplex binding and use callbacks to send and receive data. Here's an example of how to do this:

1. Create a new WCF project or add a new service to an existing project.

2. Define the service contract for the UDP communication. For example:

[ServiceContract]
public interface IUdpService
{
    [OperationContract]
    void SendData(string data);

    [OperationContract]
    string ReceiveData();
}

3. Implement the service contract in a class:

public class UdpService : IUdpService
{
    private const int Port = 12345;
    private readonly UdpClient _udpClient = new UdpClient(Port);

    public void SendData(string data)
    {
        var bytes = Encoding.ASCII.GetBytes(data);
        _udpClient.Send(bytes, bytes.Length);
    }

    public string ReceiveData()
    {
        var bytes = _udpClient.Receive(ref EndPoint);
        var data = Encoding.ASCII.GetString(bytes);
        return data;
    }
}

4. Create a custom UDP duplex binding. Add the following code to a new class:

public class UdpDuplexBinding : Binding, IDisposable
{
    private UdpClient _udpClient;

    public UdpDuplexBinding()
    {
        _udpClient = new UdpClient();
    }

    public override void Close()
    {
        _udpClient?.Close();
    }

    public override void Dispose()
    {
        Close();
        GC.SuppressFinalize(this);
    }

    // Implement other required binding members
}

5. Implement a custom UdpDuplexSessionChannel for the UDP duplex binding. Add the following code to a new class:

public class UdpDuplexSessionChannel : DuplexSessionChannel
{
    private readonly UdpClient _udpClient;

    public UdpDuplexSessionChannel(UdpClient udpClient)
    {
        _udpClient = udpClient;
    }

    protected override void OnOpen(TimeSpan timeout)
    {
        base.OnOpen(timeout);
        _udpClient.EnableBroadcast = true;
    }

    protected override void OnClose()
    {
        _udpClient.Close();
        base.OnClose();
    }

    // Implement other required session channel members
}

6. Create a custom UdpDuplexSession for the UDP duplex binding. Add the following code to a new class:

public class UdpDuplex

To remove all lines with one character from a file in Python, you can read the contents of the file, filter out the lines with one character, and then write the filtered lines back to the file. Here's an example using a simple Python script:

# Input file path
input_file_path = 'your_input_file.txt'

# Output file path
output_file_path = 'your_output_file.txt'

# Read the contents of the input file
with open(input_file_path, 'r') as input_file:
    lines = input_file.readlines()

# Filter out lines with one character
filtered_lines = [line for line in lines if len(line.strip()) > 1]

# Write the filtered lines to the output file
with open(output_file_path, 'w') as output_file:
    output_file.writelines(filtered_lines)

Open the torrent and through the "Menu" enter the subsection "Connection". Under "Proxy" choose a proxy type (Socks5 is best). In the box "Proxy" put IP address of your proxy, and in the "Port" box, respectively, the port of your proxy. If you are going to use proxy authentication, you will have to give your name and password in the corresponding fields. Click "Apply".
