MARK: - 写入cookie

class func writeCookie() {
    // 过期时间1年
    let expires: TimeInterval = 60 * 60 * 24 * 365
    
    // 定义一个可变字典存放cookie键值对
    var properties: [HTTPCookiePropertyKey : Any] = [:]
    properties[.name] = "cookieName"
    properties[.path] = "/"
    properties[.value] = "cookieValue"
    properties[.secure] = false
    properties[.domain] = "domain"
    properties[.version] = 0
    properties[.expires] = Date.init(timeIntervalSinceNow: expires)
    
    // 初始化cookie对象，返回值可选类型
    let cookie = HTTPCookie.init(properties: properties)
    if let cookie = cookie {
        // 保存cookie，地址是沙盒的 /Library/Cookies
        HTTPCookieStorage.shared.setCookie(cookie)
    }
}
