验证证书连接Betfair API时遇SSL PEM库错误求助

尝试通过证书验证连接Betfair API时触发异常，无法明确原因，相关代码、报错信息及已尝试操作如下：

代码示例 #

# Import libraries
import betfairlightweight
from betfairlightweight import APIClient
import os

# Print the current working directory
print("Current working directory:", os.getcwd())

# Print the contents of the directory
print("Contents of the directory:")
for item in os.listdir("C:\\Program Files (x86)\\xcacerts\\"):
    print(item)

# Certificate path for betfair
certs_path = "C:\\Program Files (x86)\\xcacerts\\"

# Betfair login and app key
my_username = "xxxxx"
my_password = "xxxxx"
my_app_key = "xxxxxx"

try:
    # Initialize the Betfair API client
    trading = betfairlightweight.APIClient(username=my_username,
                                          password=my_password,
                                          app_key=my_app_key,
                                          certs=certs_path)

    # Attempt to login
    trading.login()

    # Check if login was successful
    if trading.session_token:
        print("Login successful.")
    else:
        print("Login failed. Check your credentials.")

except Exception as e:
    print(f"An error occurred: {e}")

（注：已修正代码缩进问题，路径字符串添加转义反斜杠避免解析错误）

报错信息 #

An error occurred: None

Params: None

Exception: HTTPSConnectionPool(host='identitysso-cert.betfair.com', port=443): Max retries exceeded with url: /api/certlogin (Caused by SSLError(SSLError(524297, '[SSL] PEM lib (_ssl.c:3900)')))

已尝试操作 #

• 更新SSL库：确保SSL库为最新版本，通过包管理器或升级Python完成
• 验证SSL证书：检查服务器（identitysso-cert.betfair.com）使用的SSL证书是否有效且受信任，通过浏览器打开该URL查看证书详情
