我正在尝试编写一个使用Python请求模块自动下载一些文件的爬行者。但是，我遇到了一个问题。
我初始化了一个新的请求会话，然后我使用Post方法登录网站，此后，只要我尝试使用post/get方法（以下简化的代码）：
s=requests.session()
s.post(url,data=post_data, headers=headers)
#up to here everything is correct, the next step will report error
s.get(url) or s.post(url) even repeat s.post(url,data=post_data, headers=headers) will report error
它将按照下面的错误报告错误：

我完全不知道为什么会发生这种情况，有人可以帮我吗？
请求使用URLLIB3的内部版本。我的印象是，内部Urllib3之间有一个版本不匹配并请求本身。
httplib_response = conn.getResponse（buffering = true）typeerror： getResponse（）有一个意外的关键字参数'buffering'
似乎表明请求正在调用urllib3（内部版本，而不是python的），但要指定不存在的"缓冲"。
其他问题类似于我的经历。
最新的请求版本（2.6。*）还有其他问题正在解决。我怀疑您正在使用该版本。尝试倒退以前的2.4.1版，甚至是2.2.1。如果您指定，可以在程序的顶部，您要使用哪个版本：
__requires__ = ["requests==2.2.1"]
import pkg_resources
（至少在导入请求本身之前）
解决方案：上周，我与开发团队交换了几封邮件，看起来他们在修复程序方面已经生产了2.7！（实际上，我看到它仅在昨天上传到）。因此，如果您遇到类似的问题，请下载最新版本！
通过将请求升级到最新版本来解决该问题，它可能是2.6中的错误（也许是此版本，不确定）。
