Data Collection Proxy

An "open" proxy means one that is publicly available. It can be used by many network users at the same time. But because of this its bandwidth is also quite low, because the server simultaneously handles all requests through a single port.

It depends on how you plan to log in to Facebook. For example, if on a PC, just specify the proxy server settings in the connection properties or in the browser settings. If on a mobile (site or application), you need to specify the proxy data in the settings of the phone itself. Or you can install an application that allows you to automatically set up a VPN connection.

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 add a proxy in ZennoPoster, follow these steps:

1. Open ZennoPoster and go to the "Settings" menu.

2. Select "Network settings" or "Proxy settings" depending on the version you are using.

3. Click on the "Add" button to create a new proxy profile.

4. Enter the proxy server address, port, and select the protocol (HTTP or HTTPS) from the drop-down menu.

5. If your proxy requires authentication, enter the username and password in the respective fields.

6. Click "Save" to add the proxy profile.

7. To use the proxy, select it from the list of available proxies in the "Proxies" section of your task settings.

Although free proxies are popular, they are far from being flawless in their work. Many of their IP addresses are blacklisted by popular resources, and the data transfer speed and stability are very unreliable. When choosing a proxy, keep in mind that the new version of IPv6 is not supported by most websites. Note also that proxies are divided into private and public, statistical and dynamic, and support different network protocols.
