如何从iPhone上的URL接收数据？

import Foundation

let urlString = "https://www.example.com?param1=value1&param2=value2"

if let url = URL(string: urlString) {
    let components = URLComponents(url: url, resolvingAgainstBaseURL: true)

    if let queryItems = components?.queryItems {
        for item in queryItems {
            print("参数名：\(item.name)，值：\(item.value ?? "")")
        }
    }
}
