Python 客户端错误“由对等方重置连接" [英] Python client error 'Connection reset by peer'

问题描述

我编写了一个非常小的python客户端来访问confluence restful api.我正在使用 https 协议连接汇流.我遇到了 Connection reset by peer 错误.这是完整的堆栈跟踪.

I have written a very small python client to access confluence restful api. I am using https protocol to connect with the confluence. I am running into Connection reset by peer error. Here is the full stack trace.

/Users/rakesh.kumar/.virtualenvs/wpToConfluence.py/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:318: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning.

    raise ConnectionError(err, request=request)
requests.exceptions.ConnectionError: ('Connection aborted.', error(54, 'Connection reset by peer'))

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()

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:

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

(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)

它确实抱怨 python 版本号，但我不知道如何更新我的 Mac/虚拟环境 python.

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

我已经尝试 curl 命令和 Postman 对于给定的参数它们都可以正常工作.

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

推荐答案

在安装 requests 库时，它跳过了一些 可选的安全包('pyOpenSSL'、'ndg-httpsclient'和'pyasn1')，这是SSL/Https连接所必需的.您可以通过运行此命令来修复它

While installing requests library 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

pip install "requests[security]"

或

pip install pyopenssl ndg-httpsclient pyasn1
