通过python执行请求时发生SSL证书错误

Question

Iam正在尝试对HTTPS url进行API调用：

response = requests.request("GET", url, headers=headers, params=None, verify=True)

我面临以下错误。当我通过cUrl或Postman调用API时，它工作得很好。。。在

Traceback (most recent call last): File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\urllib3\connectionpool.py", line 601, in urlopen chunked=chunked) File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\urllib3\connectionpool.py", line 346, in _make_request self._validate_conn(conn) File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\urllib3\connectionpool.py", line 850, in _validate_conn conn.connect() File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\urllib3\connection.py", line 326, in connect ssl_context=context) File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\urllib3\util\ssl_.py", line 329, in ssl_wrap_socket return context.wrap_socket(sock, server_hostname=server_hostname) File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\urllib3\contrib\pyopenssl.py", line 448, in wrap_socket raise ssl.SSLError('bad handshake: %r' % e) ssl.SSLError: ("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",)

在处理上述异常时，发生了另一个异常：

Traceback (most recent call last): File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\requests\adapters.py", line 440, in send timeout=timeout File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\urllib3\connectionpool.py", line 639, in urlopen _stacktrace=sys.exc_info()[2]) File "C:\Users\user\AppData\Local\Programs\Python\Python35-32\lib\site-packages\urllib3\util\retry.py", line 388, in increment raise MaxRetryError(_pool, url, error or ResponseError(cause)) urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='freshdesk.freshsales.io', port=443): Max retries exceeded with url: /api/sales_accounts/1000080286/conversations.json?include=email_conversation_recipients,all,targetable,phone_numbe,phone_calle,note,user (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",),))

我试图指定verify=False，但仍然存在错误

有什么办法可以避免这个错误吗？我浏览了这里的各种问题，但找不到解决办法。URL管理员还确认了服务器证书是有效的，所以我觉得这肯定与一些冲突的包安装有关。在

最后发现是网络问题。我公司的IT团队把这个问题解决了，他们做了一些IP白名单。在
