import sniffer

Step 3: Enable Packet Capturing

class MyViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        // Enable packet capturing
        Sniffer.enable()

        // Send an HTTP request
        let url = URL(string: "https://www.baidu.com")!
        let request = URLRequest(url: url)
        URLSession.shared.dataTask(with: request) { data, response, error in
            // Handle the request result
        }.resume()
    }
}

Advantages

  1. Simplicity: Packet capturing can be achieved by adding a dependency and using Sniffer.
  2. Rich Functionality: Sniffer supports capturing HTTP and WebSocket requests, parsing them, and saving captured data.
  3. Compatibility: Sniffer is compatible with iOS 10 and later versions.

Example

Here's a complete example of how to use Sniffer:

// Add Dependency
dependencies: [
    .package(url: "https://github.com/LeeJay/sniffer", from: "0.1.0")
]

// Import Sniffer
import sniffer

class MyViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        // Enable packet capturing
        Sniffer.enable()

        // Send an HTTP request
        let url = URL(string: "https://www.baidu.com")!
        let request = URLRequest(url: url)
        URLSession.shared.dataTask(with: request) { data, response, error in
            // Handle the request result
        }.resume()

        // Get captured packet data
        let data = Sniffer.data

        // Parse captured data
        let request = Sniffer.parseRequest(data: data)
        let response = Sniffer.parseResponse(data: data)

        // Save captured data
        Sniffer.saveData(data: data)
    }
}

Additional Features

  • Sniffer also supports capturing HTTP and WebSocket requests, parsing them, and saving captured data.

Comparison

Compared to the native NSURLSession API, Sniffer is simpler to use and offers more extensive functionality. In comparison to other packet capturing libraries, Sniffer provides higher performance and a more stable experience.

Summary

In conclusion, Sniffer is a highly valuable open-source project that assists developers in implementing packet capturing within iOS applications. It boasts simplicity, rich functionality, strong compatibility, and is suitable for a wide range of use cases.
