解释使用Alamofire时如何管理Cookies

在Alamofire中，可以通过HTTPCookieStorage.shared来管理Cookies。Alamofire会自动处理服务器发送的Cookies，并将其存储在HTTPCookieStorage.shared中。可以通过以下方式来管理Cookies：

1. 获取所有Cookies：

if let cookies = HTTPCookieStorage.shared.cookies {
    for cookie in cookies {
        print(cookie.name)
    }
}

2. 清除所有Cookies：

let cookieStorage = HTTPCookieStorage.shared
if let cookies = cookieStorage.cookies {
    for cookie in cookies {
        cookieStorage.deleteCookie(cookie)
    }
}

3. 添加自定义Cookies：

let properties: [HTTPCookiePropertyKey: Any] = [
    .name: "cookieName",
    .value: "cookieValue",
    .domain: "example.com",
    .path: "/",
    .expires: Date(timeIntervalSinceNow: 3600),
]

if let cookie = HTTPCookie(properties: properties) {
    HTTPCookieStorage.shared.setCookie(cookie)
}

4. 设置请求时携带Cookies：

let headers: HTTPHeaders = HTTPCookie.requestHeaderFields(with: HTTPCookieStorage.shared.cookies!)
AF.request("https://example.com", headers: headers).response { response in
    print(response)
}

上面是一些基本的操作，有关更多高级用法，可以参考Alamofire的官方文档。
