Question

我是Python编程的新手，并且已经尝试过研究我的问题但是还没有找到解决方案。我希望有人可以提供帮助。

我有一个脚本可以对一个用于激活或停用Web中继交换机的IP地址进行http调用。代码的相对部分如下所示：

import requests
r = requests.get('http://192.168.1.100/state.xml?relayState=1&noReply=0')

以上成功打开了Web中继交换机，但来自Web中继的响应导致了许多异常消息，如下所示，脚本停止执行。我不需要为我的脚本处理任何响应，但如果我需要为了使脚本正常运行，我会。我的预感是问题围绕着使用xml版本1.0而不是1.1的Web中继交换机。我还没有能够强制要求使用1.0的方式。我正在使用Python 3.6.1

Answer 1

您确定网址应该是http而不是https吗？这是某人的问题：Python requests.exception.ConnectionError: connection aborted "BadStatusLine"

否则，该异常意味着错误是来自服务器的响应，我假设您无法控制。您可以与控制它的人一起打开支持票，或者，如果您赶时间，可以通过捕获并忽略异常来解决它，这很麻烦但是您可能会接受，因为您不需要响应并且知道你的请求在另一端是成功的：

let

对于生产代码，我想要了解错误的底部，但在开发期间，我可能愿意做类似以下的事情，所以我可以继续前进。

Answer 2

我是上面列出的卷筒继电器开关产品制造商的技术支持专家。最近一封支持电子邮件提到了这个帖子，我认为为其他任何可能遇到此问题的人添加信息会很好。

很久以前设计的几个较旧的模块具有有限的硬件资源，并且不支持XML响应的完整HTML标头。

几年前，这些产品使用较新的硬件进行了重新设计。出于向后兼容性原因，/ state.xml响应仍然没有完整的HTML标头，以适应那些为旧硬件系列开发软件的人。

新产品现在支持完整的HTML标头，但必须提出不同的请求 - /stateFull.xml。

原始示例的正确代码如下：

import requests
r = requests.get('http://192.168.1.100/stateFull.xml?relayState=1&noReply=0')

注意：首次提交到StackOverflow，所以我为缺少通常遵循的任何约定而道歉。

xml获取使用请求库导致异常
