Python10054尝试使用请求库登录航空公司网站时出错

Question

我正在学习python，作为我的第一个项目，我想登录几家航空公司的网站，收集我的飞行里程信息。我已经成功地登陆美国航空公司和美国联合航空公司，但在达美航空公司、美国航空公司和英国航空公司，我都做不到。在

我一直使用的方法是从Fiddler2、Chrome或Firebug观察网络流量。Wireshark目前看来太复杂了。在

为了让我的脚本与American和United scraping一起工作，我所做的只是观察fiddler2上的流量，复制表单数据和请求头数据，然后使用python第三方请求库来访问数据。很简单。很简单。另一家航空公司的网站给了我很多麻烦。在

让我们具体谈谈英国航空公司。下面是我登录虚拟BA帐户时从fiddler获取的表单数据和请求头数据的图片。我还包括了我一直在使用的测试脚本。我写了两个不同的版本。一个使用请求库，一个使用urllib。它们都会产生相同的错误，但我想我会提供这两种方法，以便在没有导入请求库的情况下更容易帮助我。用你喜欢的那个。在

基本上，当我请求.post我得到了

10054，“远程主机强制关闭了现有连接”错误。在

我不知道发生了什么事。找了3天，什么也没找到。我希望有人能帮助我。下面的代码是使用我的虚拟BA帐户信息。用户名：python\u noob密码：p4ssword。请随意使用和测试它。在

这是一些图片的数据

Answer 1

在python3.3的windows版本中似乎有一个bug是我问题的原因。我从这里得到了答案

HTTPS request results in reset connection in Windows with Python 3

在我的脚本的urllib版本上取得进展。我想使用请求，所以我需要弄清楚如何使用该模块进行SSL降级工作。我会把那条线分开。如果有人对此有答案，你也可以在这里发表。谢谢。在
