如何修复我的 SSL 证书？我的 Python 脚本出现 SSL 证书失败

Question

我正在尝试创建一个简单的 Slack 机器人。但是，在测试机器人是否可以工作时，我收到 SSL 证书错误。如果我将解决方法硬编码到脚本中，我就可以完成这项工作，但理想情况下我希望它准备好投入生产。

代码和错误代码如下。

代码

import os
import slack
import ssl

# Function to load environment variables from .env file
def load_env():
    with open('.env', 'r') as file:
        for line in file.readlines():
            if line.startswith('SLACK_BOT_TOKEN'):
                key, value = line.strip().split('=')
                os.environ[key] = value

# Load environment variables
load_env()

token = os.getenv("SLACK_BOT_TOKEN")

# Function to post a message to Slack
def post_message():
    try:
        # Create a WebClient using the given token
        client = slack.WebClient(token)
        
        # Post a message to the 'test' channel
        response = client.chat_postMessage(channel='test', text="Hello World!")

        # Print the response
        print(response)

    except ssl.SSLCertVerificationError as e:
        print("SSL Certificate Verification Failed:")
        print(e)

        # Optional: Add code here to send an alert or log the error for further investigation.

    except Exception as e:
        print("An unexpected error occurred:")
        print(e)

# Check if the token is available
if token:
    post_message()
else:
    print("Token not found.")

错误代码

<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1002)>

我已经更新了我的电脑，安装了证书，进入我的互联网设置并检查了 SSL 和 TSL 是否已启用；但仍然没有积极的结果。

我认为你需要在通话中使用 ssl 上下文

见 https://stackoverflow.com/a/70853605/22187484

import ssl
import certifi
ssl_context = ssl.create_default_context(cafile=certifi.where())
client = slack.WebClient(token=token, ssl=ssl_context)

我的谷歌搜索是

python slack.WebClient ssl
