Here is my client code:

这是我的客户端代码：

import requests


def main():
    auth = open('/tmp/confluence', 'r').readline().strip()

    username = 'rakesh.kumar'

    response = requests.get("https://<HOST-NAME>/rest/api/content/",
                            auth=(username, auth),
                            headers={'content-type': 'application/json'})
    print response

if __name__ == "__main__":
    main()

I am running this script in a virtual environment and following packages are installed on that environment:

我在虚拟环境中运行此脚本，并在该环境中安装了以下软件包：

(wpToConfluence.py)?  Python pip list
You are using pip version 6.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
appnope (0.1.0)
backports.shutil-get-terminal-size (1.0.0)
decorator (4.0.10)
ipdb (0.10.1)
ipython (5.0.0)
ipython-genutils (0.1.0)
pathlib2 (2.1.0)
pexpect (4.2.0)
pickleshare (0.7.3)
pip (6.1.1)
prompt-toolkit (1.0.5)
ptyprocess (0.5.1)
Pygments (2.1.3)
requests (2.10.0)
setuptools (25.1.6)
simplegeneric (0.8.1)
six (1.10.0)
traitlets (4.2.2)
urllib3 (1.16)
wcwidth (0.1.7)

It does complain about the python version number but I am not sure how to update my Mac/Virtual environment python.

它确实抱怨 python 版本号，但我不确定如何更新我的 Mac/虚拟环境 python。

I have tried to curl command and Postman both of them work fine for the given parameters.

我曾尝试 curl 命令和 Postman 对于给定的参数，它们都可以正常工作。

While installing requestslibrary it skips few of optional security packages('pyOpenSSL', 'ndg-httpsclient', and 'pyasn1') which are required for the SSL/Https connection. You can fix it by either running this command

在安装requests库时，它会跳过SSL/Https 连接所需的一些可选安全包（“pyOpenSSL”、“ndg-httpsclient”和“pyasn1”）。您可以通过运行此命令来修复它

pip install "requests[security]"

or

或者

pip install pyopenssl ndg-httpsclient pyasn1

I tried installing all the optional security packages provided in the answer above. But nothing seemed to work.

我尝试安装上述答案中提供的所有可选安全包。但似乎没有任何效果。

One important GOTCHA : Check if your url end-point actively prevents programmatic access.

一个重要的 GOTCHA ：检查您的 url 端点是否主动阻止编程访问。

Take a look at the robots.txt file in the root directory of a website: http://myweburl.com/robots.txt.

查看网站根目录下的 robots.txt 文件：http: //myweburl.com/robots.txt。

If it contains text that looks like this : User-agent: * Disallow: /

如果它包含如下所示的文本： User-agent: * Disallow: /

This site doesn't like and want scraping. This gives you the same dreaded error 54, connection reset by the peer.

这个网站不喜欢，想要刮。这会给你同样可怕的错误 54，连接被对方​​重置。
