在Swift中缩短URL

import Foundation

func shortenURL(longURL: String) {
    let apiKey = "YOUR_API_KEY"
    let apiUrl = "https://api-ssl.bitly.com/v4/shorten"

    guard let url = URL(string: apiUrl) else {
        print("Invalid URL")
        return
    }

    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.setValue("Bearer \(apiKey)", forHTTPHeaderField: "Authorization")
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")

    let parameters: [String: Any] = [
        "long_url": longURL
    ]

    guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: []) else {
        print("Invalid parameters")
        return
    }

    request.httpBody = httpBody

    let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
        if let error = error {
            print("Error: \(error)")
            return
        }

        guard let data = data else {
            print("No data received")
            return
        }

        do {
            if let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any],
               let shortURL = json["id"] as? String {
                print("Short URL: \(shortURL)")
            }
        } catch {
            print("Error parsing JSON: \(error)")
        }
    }

    task.resume()
}

// Usage
let longURL = "https://www.example.com/long-url"
shortenURL(longURL: longURL)
