最近运维上需要在测试环境调用http的post请求，实现自动化日切，我看了下我会的编程，也就python能符合我的要求，且简单好操作。但是在实际操作过程遇到了一些问题，其中最大的就是测试环境的机器是外网隔离的，没法连外网进行直接安装部分模块，通过搜索和实践之后，简单说下我的经验。

机器环境

操作系统：Windows Server 2012 x64

python3安装

从 [官网] 下载最新的适合windows 的安装包。

下载下来的python-3.7.4-amd64.exe，直接拷贝到测试环境的机器上，双击安装即可，需要注意的是，最好勾选 AddPython 3.7 to PATH，这样后期直接在cmd窗口中就可以调用python命令了。

requests模块的依赖包检查

在可以上网且已安装python的机器上检查requests模块需要哪些依赖包，要是没有依赖包，直接下载一个直接安装最好。

在CMD命令窗口中输入 pip show requests

C:\Users\Laycher>pip show requests
Name: requests
Version: 2.18.4
Summary: Python HTTP for Humans.
Home-page: http://python-requests.org
Author: Kenneth Reitz
Author-email: me@kennethreitz.org
License: Apache 2.0
Location: d:\program files\python3\lib\site-packages
Requires: chardet, urllib3, idna, certifi
Required-by:

发现需要chardet，urllib3，idna，certifi

下载依赖包模块和requests模块

在网站 https://www.lfd.uci.edu/~gohlke/pythonlibs 上找到相应的程序，下载。

certifi-2019.9.11-py2.py3-none-any.whl

chardet-3.0.4-py2.py3-none-any.whl

idna-2.8-py2.py3-none-any.whl

requests-2.22.0-py2.py3-none-any.whl

urllib3-1.25.6-py2.py3-none-any.whl

安装模块

将以上下载的文件传到测试环境。离线装模块。

安装命令为 pip install XXXXX.whl

切记，先安装依赖包，如果直接安装requests，由于有依赖包，还是会去连外网找依赖包。
