python模拟登陆12306

[sun6623518]

请教各位高手：
我尝试用下面代码去模拟登陆12306，验证码下载成功，验证也成功。
在第四步登陆http://kyfw.12306.cn/otn/login/loginAysnSuggest的时候
为啥最后返回结果总是，“网络忙，请刷新重试”

不好意思是我的疏忽，第61行 LoginUrl = "http://kyfw.12306.cn/otn/login/loginAysnSuggest"; 应该写为https的 LoginUrl = "https://kyfw.12306.cn/otn/login/loginAysnSuggest"; 这就结贴。

是不是被封IP了？还是他检测到你不熟正常的浏览器登录。

没有被封呢，我浏览器用12306正常 我在User-Agent字段已经伪装成浏览器了

代码很好，不过同学，你还是把自己的12306密码修改下吧

因为安装的是python3.2版本，所以改造了一下，但是发现还是有问题，提示网络忙，关闭插件重试。可能12306反爬升级了吧。这里有个py2的例子，不过比较新，看了看貌似要解析一段js，顺便提交到登录的data里面，可能原因在这。无奈没怎么找到解析js的模块在py3里面，有没有好的解决办法......(想把改过的代码文件附过来，没发现添加附件的地方啊）
