将Cookie设置为来自Swift NSURLSession的HTTP POST请求

import Foundation

// 创建URL对象
let url = URL(string: "http://example.com/post")

// 创建请求对象
var request = URLRequest(url: url!)
request.httpMethod = "POST"

// 创建Cookie
let cookieProperties = [
    HTTPCookiePropertyKey.name: "session",
    HTTPCookiePropertyKey.value: "1234567890",
    HTTPCookiePropertyKey.domain: "example.com",
    HTTPCookiePropertyKey.path: "/"
]
if let cookie = HTTPCookie(properties: cookieProperties) {
    // 将Cookie添加到请求头部
    let cookieHeader = "\(cookie.name)=\(cookie.value)"
    request.setValue(cookieHeader, forHTTPHeaderField: "Cookie")
}

// 发送请求
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
    // 处理响应
    if let error = error {
        print("Error: \(error)")
    } else if let data = data {
        let responseString = String(data: data, encoding: .utf8)
        print("Response: \(responseString ?? "")")
    }
}
task.resume()
