'[SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败：无法获取本地颁发者证书 (_ssl.c:997)')))

Question

使用此代码时，会生成以下错误：

exchangelib.errors.TransportError: HTTPSConnectionPool(host='mail.rt.yu', port=443): Max retries exceeded with url: /EWS/Exchange.asmx (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)')))

如何提供本地颁发者证书或以其他方式解决问题？

from exchangelib import Credentials,DELEGATE, IMPERSONATION, Account,Message, Mailbox, FileAttachment,Configuration

credentials = Credentials(username=r'sinai\afgggn.t.auu',
                             password='SSft@y155')
config = Configuration(server='mail.te.eg', credentials=credentials)
account = Account(primary_smtp_address='afgggn.t.auu', config=config,
                  autodiscover=False, access_type=DELEGATE)
for item in account.inbox.all().order_by('-datetime_received')[:100]:
    print(item.subject, item.sender, item.datetime_received)

更新这是经过千辛万苦寻找解决方案后的问题解决方案将域验证证书下载为 *.crt 或 *pem 文件在编辑器中打开文件并将其内容复制到剪贴板找到你的 cacert.pem 位置：from requests.utils import DEFAULT_CA_BUNDLE_PATH;打印（DEFAULT_CA_BUNDLE_PATH）编辑 cacert.pem 文件并将您的域验证证书粘贴到文件末尾。保存文件并享受请求！

Answer 1

exchangelib 使用 requests 来执行实际的 HTTP 请求。这意味着您可以设置 REQUESTS_CA_BUNDLE 环境变量。参见 How to force requests use the certificates on my ubuntu system
