在Swift中获取特定的json数据

guard let url = URL(string: "https://example.com/data.json") else {
    print("Invalid URL")
    return
}

let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
    if let error = error {
        print("Error: \(error.localizedDescription)")
        return
    }
    
    guard let data = data else {
        print("No data received")
        return
    }
    
    // 在这里解析JSON数据
}
task.resume()

do {
    if let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] {
        // 在这里处理解析后的JSON数据
    }
} catch {
    print("JSON parsing error: \(error.localizedDescription)")
}

struct Person: Codable {
    let name: String
    let age: Int
}

do {
    let person = try JSONDecoder().decode(Person.self, from: data)
    print("Name: \(person.name), Age: \(person.age)")
} catch {
    print("JSON decoding error: \(error.localizedDescription)")
}
