Bj Proxy

In data centers, proxies are used to provide IP to virtual servers. After all, one server there can be used by a dozen users at the same time. And each needs to be allocated its own IP and port. All this is done through proxies.

In PHP, you can generate JSON data using the json_encode function, and in Swift (iOS/macOS), you can parse it using JSONSerialization or Codable depending on your needs.

Here's an example of generating JSON in PHP and parsing it using NSJSONSerialization in Swift

PHP (Generate JSON):

 'John Doe',
    'age' => 25,
    'city' => 'New York',
    'is_student' => true
);

// Encode data to JSON
$jsonData = json_encode($data);

// Output JSON
echo $jsonData;
?>

In this PHP script, the json_encode function is used to convert the PHP associative array into a JSON string.

Swift (Parse JSON using NSJSONSerialization):

import Foundation

// Sample JSON data as a string
let jsonString = """
{
    "name": "John Doe",
    "age": 25,
    "city": "New York",
    "is_student": true
}
"""

// Convert JSON string to Data
if let jsonData = jsonString.data(using: .utf8) {
    do {
        // Parse JSON data using NSJSONSerialization
        if let jsonObject = try JSONSerialization.jsonObject(with: jsonData, options: []) as? [String: Any] {
            // Access parsed JSON data
            let name = jsonObject["name"] as? String ?? ""
            let age = jsonObject["age"] as? Int ?? 0
            let city = jsonObject["city"] as? String ?? ""
            let isStudent = jsonObject["is_student"] as? Bool ?? false

            // Print parsed data
            print("Name: \(name)")
            print("Age: \(age)")
            print("City: \(city)")
            print("Is Student: \(isStudent)")
        }
    } catch {
        print("Error parsing JSON: \(error.localizedDescription)")
    }
}

In this Swift code, the JSONSerialization class is used to parse the JSON string (converted to Data) into a Swift dictionary ([String: Any]). You can then access individual values from the parsed JSON data.

Note: Ensure that the JSON structure in your PHP script and Swift code aligns, and handle errors appropriately during parsing. Additionally, consider using Codable in Swift for a more convenient way to work with JSON data if your data structure matches your Swift model.

To scrape comments from an XML file using C#, you can use the XmlDocument class, which is part of the System.Xml namespace. Here's a basic example demonstrating how to read and extract comments from an XML file:

using System;
using System.Xml;

class Program
{
    static void Main()
    {
        string xmlFilePath = "path/to/your/xml/file.xml"; // Replace with the path to your XML file

        try
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(xmlFilePath);

            // Extract comments from the XML document
            ExtractComments(xmlDoc);
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error: {ex.Message}");
        }
    }

    static void ExtractComments(XmlDocument xmlDoc)
    {
        XmlNodeList commentNodes = xmlDoc.SelectNodes("//comment()");

        if (commentNodes != null)
        {
            foreach (XmlNode commentNode in commentNodes)
            {
                // Print or process the comment content
                string commentContent = commentNode.Value;
                Console.WriteLine($"Comment: {commentContent}");
            }
        }
        else
        {
            Console.WriteLine("No comments found in the XML document.");
        }
    }
}

In this example:

1. Replace the xmlFilePath variable with the actual path to your XML file.
2. The XmlDocument class is used to load the XML file.
3. The ExtractComments method uses an XPath expression (//comment()) to select all comment nodes in the XML document.
4. The comments are then printed or processed as needed.

Make sure to handle exceptions appropriately and adapt the code based on the structure of your XML file. If your XML file is hosted on the web, you can use XmlDocument.Load with a URL instead of a local file path.

After editing is complete, the proxy must be disabled in order to send the video for color correction. To do this, select all the proxies in the project window and choose the "Switch offline" command from the context menu. Then, after making sure that the "Media files remain on disk" option is active, click "Ok". If after that the program monitor window is filled with red color, do not be frightened, it is normal.

When using a proxy, Google Chrome warns the user about it at startup. To connect directly, you must disable proxies at system level. That is, go to "Settings" Windows, then - "Network and Internet", in the section "Proxy server" disable the corresponding item.
