如何将字母'&‘作为url参数发送- swift

import Foundation

// 创建URLComponents对象
var urlComponents = URLComponents()
urlComponents.scheme = "https"
urlComponents.host = "example.com"
urlComponents.path = "/api"
urlComponents.queryItems = [
    URLQueryItem(name: "param1", value: "value1"),
    URLQueryItem(name: "param2", value: "value2&value3")
]

// 获取完整的URL
if let url = urlComponents.url {
    // 发送请求
    let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
        if let error = error {
            print("请求失败：\(error)")
        } else if let data = data {
            // 处理响应数据
            let responseString = String(data: data, encoding: .utf8)
            print("响应数据：\(responseString ?? "")")
        }
    }
    task.resume()
}
