os.environ.get()不会在Windows中返回环境值吗?

问题描述

我已经设置了SLACK_TOKEN环境变量.但是"SLACK_TOKEN=os.environ.get('SLACK_TOKEN')"返回无". SLACK_TOKEN 的类型为 NoneType .我认为os.environ.get无法获取环境变量的值.因此其余代码无法执行.

I already set SLACK_TOKEN environment Variable. But "SLACK_TOKEN=os.environ.get('SLACK_TOKEN')" is returning "None".The type of SLACK_TOKEN is NoneType. I think os.environ.get not fetching value of environment variable. so rest of the code is not executing.

import os
from slackclient import SlackClient


SLACK_TOKEN= os.environ.get('SLACK_TOKEN') #returning None
print(SLACK_TOKEN) # None
print(type(SLACK_TOKEN)) # NoneType class

slack_client = SlackClient(SLACK_TOKEN)
print(slack_client.api_call("api.test")) #{'ok': True}
print(slack_client.api_call("auth.test")) #{'ok': False, 'error': 'not_authed'}


def list_channels():
    channels_call = slack_client.api_call("channels.list")
    if channels_call['ok']:
        return channels_call['channels']
    return None

def channel_info(channel_id):
    channel_info = slack_client.api_call("channels.info", channel=channel_id)
    if channel_info:
        return channel_info['channel']
    return None

if __name__ == '__main__':
    channels = list_channels()
    if channels:
        print("Channels: ")
        for c in channels:
            print(c['name'] + " (" + c['id'] + ")")
            detailed_info = channel_info(c['id'])
            if detailed_info:
                print(detailed_info['latest']['text'])
    else:
        print("Unable to authenticate.") #Unable to authenticate

推荐答案

我遇到了类似的问题.我通过从值中删除引号来解决了该问题.例子:我创建了一个local.env文件，其中存储了我的密钥值:

I faced similar issue.I fixed it by removing quotes from the values.Example:I created a local.env file wherein I stored my secret key values :

*local.env:*
export SLACK_TOKEN=xxxxxyyyyyyyzzzzzzz

*settings.py:*
SLACK_TOKEN = os.environ.get('SLACK_TOKEN')

在您的python终端或控制台中，运行命令:*source local.env*

In your python terminal or console,run the command : *source local.env*

****将local.env包含在gitignore中.请确保不要将其推送到git中，以保护您的信息.

****Involve local.env in gitignore.Make sure you dont push it to git as you have to safeguard your information.

这仅适用于本地服务器.希望对您有所帮助.编码愉快:)

This is applicable only to the local server.Hope this helps.Happy coding :)
