Python脚本通过Twilio API返回SSL错误

Question

我正在尝试运行一个基本的SMS脚本(请参阅下文(。

为了绕过下面脚本中的错误，我尝试了：

1. 在Twilio控制台中禁用SSL进行测试
2. 从这里安装.pem文件：https://curl.haxx.se/docs/caextract.html到一个文件夹，然后在这里执行以下步骤(除了引用ca-cert.pem文件名(

# Download the helper library from https://www.twilio.com/docs/python/install
from twilio.rest import Client
# Your Account Sid and Auth Token from twilio.com/console
# DANGER! This is insecure. See http://twil.io/secure
account_sid = '###############################'
auth_token = '##############################'
client = Client(account_sid, auth_token)
message = client.messages 
.create(
body="Join Earth's mightiest heroes. Like Kevin Bacon.",
from_='+########',
to='+########'
)
print(message.sid)

我得到以下错误。

您可能正在使用虚拟环境。在我的情况下，我使用Anaconda，这是我解决这个问题的方法：

(来源：https://github.com/conda/conda/issues/8273)

我引用：

我的解决方法：我已经复制了以下文件

• libcrypto-1_1-x64*
• libssl-1-1-x64*

从D:Anaconda3Librarybin到D:Anaconda3DLLs。

它是一种魅力！
