模拟艺龙旅游网登录，提供参考内容，内容如下：

模拟艺龙旅游网登录流程：

1. 想象模拟登录艺龙旅游网，首先需要整理以下流程： 1. 使用360浏览器（IE、火狐等）F12开发者工具捕捉相关数据。 2. 获取验证码（通常通过cookie获取）。 3. 登录时输入用户名和密码，同时确保验证码正确。

模拟艺龙旅游网登录，供大家参考，具体内容如下

想模拟登录，首先整理一下流程

1.通过360浏览器(IE,火狐等等)F12开发人员工具抓到相关数据

2.获取验证码（拿到cookie），登录时也需要使用

3.登录

F12调出开发人员工具，输入用户名，密码登录，看我们抓到了什么信息。

Request URL:这个就是登录请求的url
secure.elong.com/passport/ajax/elongLogin

方式POST
Form Data:这个是我们要POST传输的数据：

userName=xzdylyh&passwd=12313&validateCode=验证码&rememberMe=false

其它一些重要信息在Request Headers中

我使用C# 设计的winform界面

最后执行效果，登录的session已经成功返回。
