Question

我的设置是Mac OS 10.13.6（更新），python 2.7.15，并且使用VPN连接（我需要安装VPN证书才能解密HTTPs流量）。问题是我无法连接到Slack API

>>> import slackclient
>>> client = slackclient.SlackClient(myToken)
>>> client.server.rtm_connect()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/slackclient/server.py", line 131, in rtm_connect
    reply = self.api_requester.do(self.token, connect_method, timeout=timeout, post_data=kwargs)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/slackclient/slackrequest.py", line 104, in do
    proxies=self.proxies

    return request('post', url, data=data, json=json, **kwargs)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/requests/api.py", line 58, in request
    return session.request(method=method, url=url, **kwargs)

    resp = self.send(prep, **send_kwargs)

    r = adapter.send(request, **kwargs)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/requests/adapters.py", line 511, in send
    raise SSLError(e, request=request)
requests.exceptions.SSLError: HTTPSConnectionPool(host='slack.com', port=443): Max retries exceeded with url: /api/rtm.start (Caused by SSLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:726)'),))

版本为：

Answer 1

我发现了问题。由于某种原因，python不使用我的密钥链中的证书，而是使用/library/Frameworks/Python.framework/Versions/2.7/etc/openssl/cert.pem

下的openssl中的证书。

我已经在文件底部添加了证书，问题就消失了

另一种解决方案，当slackclient调用websocket-client时添加No cert选项在文件“ c：/Python27/Lib/site-packages/slackclient/server.py”中

添加第180行，sslopt = {'cert_reqs'：0}

line 176:            self.websocket = create_connection(ws_url,
line 177:                                               http_proxy_host=proxy_host,
line 178:                                               http_proxy_port=proxy_port,
line 179:                                               http_proxy_auth=proxy_auth,
line 180:                                               sslopt={'cert_reqs':0})

另一种解决方案，在您的钥匙串访问权限中，删除slack.com令牌

尝试使用slackclient和python 2.7时获取CERTIFICATE_VERIFY_FAILED
