本文介绍了一种解决Python脚本访问MinIO服务时出现的HTTPS证书验证失败问题的方法。通过禁用证书验证并配置自定义HTTP客户端，成功绕过了证书错误，实现了对MinIO服务的正常访问。

搭建了minio服务，支持https，python调用报错：

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='xx.xx.xx.xxx', port=9000): Max retries exceeded with url: /allstruct?location= (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate (_ssl.c:1108)')))

忽略证书错误问题，试用一下demo脚本


import os
from minio import Minio
import urllib3
from urllib.parse import urlparse
import certifi
from minio.commonconfig import REPLACE, CopySource
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)


minio_endpoint = os.getenv("MINIO_ENDPOINT", "https://xxx.xxx.xxx.xxx:9000")
secure = True

minio_endpoint = urlparse(minio_endpoint)


if minio_endpoint.scheme == 'https':
    secure = True

ok_http_client=urllib3.PoolManager(
            timeout=urllib3.util.Timeout(connect=10, read=10),
            maxsize=10,
            cert_reqs='CERT_NONE',
            ca_certs= os.environ.get('SSL_CERT_FILE') or certifi.where(),
            retries=urllib3.Retry(
                total=5,
                backoff_factor=0.2,
                status_forcelist=[500, 502, 503, 504]
            )
        )


minioClient = Minio(minio_endpoint.netloc,
                    access_key='username',
                    secret_key='password',
                    http_client=ok_http_client,
                    secure=secure)

print(minioClient.list_buckets())
