Question

嘿伙计们，我有一个情况......

我正在开发一个java程序，我的客户端想要登录到具有给定凭据的网站，然后将文件上传到同一网站的URL ...问题是客户端是否知道用户登录是否是使用cookie或会话进行身份验证和设置..

我使用HttpClient进行登录和上传，我完成了代码编写..问题是当上传文件时我得到“403 Forbidden”。有没有办法获取cookie和会话列表，以便我可以从登录URL输出中获取它并将其设置为上传，以便认为该请求来自经过身份验证的用户。

有关更多参考，请附上脚本：

    }

    public static void main(String[] args) {
        new Main().sendLoginRequest();
    }
}

我需要显示用户登录的上传页面，以便上传...

谢谢...

获取Cookies＆amp;会话并使用HttpClient再次设置
