如何用python脚本以环境变量输出秘密令牌？

Question

正在使用slack 注册聊天机器人，需要连接slack API,给出了一个秘密令牌，不知道怎么将这个秘密令牌输出环境变量中，是写在python脚本文件中吗，可是我执行python解释器的时候总是报错，请问这是怎么回事？

That’s not the case. If you are under Linux, just execute this sentence in the terminal:

export SLACK_BOT_TOKEN="*******"

So you can use the following statement in python to get:

import os
token = os.getenv("SLACK_BOT_TOKEN")

Or you can just put SLACK_BOT_TOKEN写到.bashrc inside.

If you are using Windows, it is different. It seems to be executed under cmd:

set SLACK_BOT_TOKEN="*******"

In [57]: os.environ["testtest"]="test"

In [58]: os.environ.get("testtest")
Out[58]: 'test'
