Proxy RFC

In Swift, you can use the Codable protocol to parse JSON data into Swift objects. Here's a basic example:

Assuming you have the following JSON data:

{
    "name": "John Doe",
    "age": 30,
    "city": "New York"
}

And you want to create a Swift struct to represent this data:

import Foundation

// Define a struct conforming to Codable
struct Person: Codable {
    let name: String
    let age: Int
    let city: String
}

// JSON data
let jsonData = """
{
    "name": "John Doe",
    "age": 30,
    "city": "New York"
}
""".data(using: .utf8)!

// Use JSONDecoder to decode JSON data into a Person object
do {
    let person = try JSONDecoder().decode(Person.self, from: jsonData)
    print("Name: \(person.name)")
    print("Age: \(person.age)")
    print("City: \(person.city)")
} catch {
    print("Error decoding JSON: \(error)")
}

In this example:

• We define a Person struct that conforms to the Codable protocol. The struct's properties match the keys in the JSON data.
• We create a JSON string and convert it to Data using data(using:).
• We use JSONDecoder to decode the JSON data into an instance of the Person struct.

Ensure that the keys in your Swift struct match the keys in your JSON data, and the data types match accordingly. The JSONDecoder automatically maps the JSON data to the struct based on the property names.

This example assumes a simple JSON structure. If your JSON structure is more complex, you may need to define additional structs conforming to Codable to represent nested structures.

Note: If your JSON data comes from a URL, you can also use URLSession to fetch the data.

To save cookies in SQLite3 using Selenium, you'll need to follow these steps:

1. Install the required packages: Make sure you have Selenium and SQLite3 installed. You can install SQLite3 using pip:

pip install sqlite3

2. Connect to the SQLite3 database: Before saving cookies to SQLite3, you need to establish a connection to the database.

import sqlite3

# Connect to the SQLite3 database (or create it if it doesn't exist)
conn = sqlite3.connect("cookies.db")
cursor = conn.cursor()

# Create the cookies table if it doesn't exist
cursor.execute("""
CREATE TABLE IF NOT EXISTS cookies (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT NOT NULL,
    value TEXT NOT NULL,
    domain TEXT NOT NULL,
    path TEXT NOT NULL,
    expiry TEXT NOT NULL
)
""")

# Commit the changes and close the connection
conn.commit()
conn.close()

3. Save cookies to SQLite3 using Selenium: In your Selenium code, you can save cookies to the SQLite3 database by iterating through the cookies in the browser and inserting them into the database.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import sqlite3

# Set the path to the ChromeDriver executable
chrome_driver_path = "path/to/chromedriver"

# Set the preference to save downloaded files with a specific name pattern
options = Options()
options.add_argument("download.default_directory='path/to/download/folder'")
options.add_argument(f"download.download_path='path/to/download/folder'")
options.add_preference("download.filename_template", "%f - %r")

# Initialize the Chrome WebDriver with the specified options
driver = webdriver.Chrome(executable_path=chrome_driver_path, options=options)

# Your Selenium code goes here

# Connect to the SQLite3 database
conn = sqlite3.connect("cookies.db")
cursor = conn.cursor()

# Get all cookies from the browser
cookies = driver.get_cookies()

# Insert cookies into the SQLite3 database
for cookie in cookies:
    cursor.execute("""
    INSERT INTO cookies (name, value, domain, path, expiry)
    VALUES (?, ?, ?, ?, ?)
    """, (cookie['name'], cookie['value'], cookie['domain'], cookie['path'], cookie['expiry']))

# Commit the changes and close the connection
conn.commit()
conn.close()

# Your code to save the cookies to SQLite3

# Close the browser
driver.quit()

Replace path/to/chromedriver, path/to/download/folder, and %f - %r with the appropriate values for your setup.

This example saves the cookies from the browser to the SQLite3 database. You can modify the code to load cookies from the database and set them in the browser as needed.

Setting up a proxy refers to the process of configuring a system or network to act as an intermediary between a client and a server, allowing for the routing of requests and responses through the proxy server. This can be done for various reasons, such as improving security, anonymity, or performance.

When a proxy is set up, the client sends its requests to the proxy server, which then forwards the requests to the appropriate server on behalf of the client. The proxy server can perform various tasks, such as caching, filtering, and authentication, before returning the response to the client.

There are different types of proxy servers, including HTTP, SOCKS, and Transparent proxies, each with its own set of features and use cases. Setting up a proxy can be done on various levels, such as on an individual computer, a local network, or a large-scale enterprise network.

To check if a proxy server is working, you can follow these steps:

1. Open your web browser and go to a website that is not blocked by your proxy server.

2. In the address bar, enter the proxy server address and port number in the following format: http://proxy-server-address:port-number

3. Press Enter and wait for the page to load. If the page loads successfully, it means your proxy server is working.

4. If the page does not load or you see an error message, it means your proxy server is not working or is blocked by the website you are trying to access.

Alternatively, you can use online tools like Proxy Checker (https://www.proxychecker.com/) to test your proxy server. These tools will provide you with information on whether your proxy server is working or not.

This is a proxy server integrated into the app to redirect traffic. It allows you to protect yourself from being tracked or to use the program where it is blocked. For example, at one time, users used a proxy server to bypass Telegram blocking.
