标签: urllib3

我正在编写一个涉及CAS,jspring安全检查,重定向等的简单脚本.我想使用Kenneth Reitz的python请求,因为它是一项很棒的工作!但是,CAS需要通过SSL进行验证,因此我必须先通过该步骤.我不知道Python的要求是什么？这个SSL证书应该驻留在哪里？

我正在使用pyVmomi在Python2.6中编写脚本,并使用其中一种连接方法:

service_instance = connect.SmartConnect(host=args.ip,
                                        user=args.user,
                                        pwd=args.password)

我收到以下警告:

/usr/lib/python2.6/site-packages/requests/packages/urllib3/connectionpool.py:734: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.org/en/latest/security.html
  InsecureRequestWarning)

有趣的是,我没有使用pip安装urllib3(但它位于/usr/lib/python2.6/site-packages/requests/packages/urllib3/).

我按照这里的建议尝试过

import urllib3
...
urllib3.disable_warnings()

但这并没有改变任何事情.

之后pip install openai，当我尝试时import openai，它显示此错误：

urllib3 的“ssl”模块是使用 LibreSSL 而不是 OpenSSL 编译的

我刚刚学习了一个关于使用 OpenAI API 的项目教程。但是当我到达第一步，即安装并导入 OpenAI 时，我陷入了困境。我试图找到该错误的解决方案，但一无所获。

这是我尝试导入 OpenAI 后的消息：

我在使用python 2.7.9-2 amd64的Debian 8系统上遇到了问题:

我想写一段代码,如下所示:

from bs4 import BeautifulSoup
import urllib2

url = 'http://www.thefamouspeople.com/singers.php'
html = urllib2.urlopen(url)
soup = BeautifulSoup(html)

但我发现我现在必须安装urllib3包.

此外,我找不到任何教程或示例来了解如何重写上面的代码,例如,urllib3没有urlopen.

请问任何解释或示例？!

P/S:我正在使用python 3.4.

p={
    'http':'http://my correct proxy here',
    'https':'https://my correct proxy here'
    }
self.response=requests.get(url=url,headers=self.headers,timeout=(6,15),proxies=p)

然后它引发异常：

Traceback (most recent call last):

是否看到

urllib3.connectionpool WARNING - Connection pool is full, discarding connection

意味着我正在有效地丢失数据（因为连接丢失）
或者这
是否意味着连接被丢弃（因为池已满）；但是，当连接池可用时，稍后会重试相同的连接吗？

我将数以亿计的项目通过REST API从Heroku上的云服务器上传到我的数据库到AWS EC2中的数据库.我正在使用Python,我不断在日志中看到以下INFO日志消息.

[requests.packages.urllib3.connectionpool] [INFO] Resetting dropped connection: <hostname>

在我的代码继续执行之前,这种"重置丢弃的连接"似乎需要很多秒(有时30秒以上).

• 首先,这里究竟发生了什么,为什么？
• 其次有没有办法阻止连接丢失,以便我能够更快地上传数据？

谢谢你的帮助.安德鲁.

我正在尝试使用依赖于Python请求的包与我的Python 2.7 shell中的API进行交互.事情是我的网络(大学图书馆)阻止了远程地址.

所以说到API,我会做以下事情:

~$ ssh -D 8080 name@myserver.com

然后,在新的终端,在本地计算机:

~$ export http_proxy=socks5://127.0.0.1:8080 https_proxy=socks5://127.0.0.1:8080

然后我在Python控制台中运行该程序但失败了:

~$ python
>>> import myscript
>>> id = '1213'
>>> token = 'jd87jd9'
>>> connect(id,token)

我找到了几个关于这个问题的网页,但没有一个解决了我的问题.

即使我做了:

pip show

我明白了:
