SSL 证书验证失败 - 雅虎财经 API - Python

Question

我正在尝试从雅虎财经获取数据，但收到 SSL 错误。代码如下：

import requests
response = requests.get("https://query1.finance.yahoo.com/v8/finance/chart/META", verify=True)
print(response.status_code)

出现以下错误：

urllib3.exceptions.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1000)

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/requests/adapters.py", line 486, in send

During handling of the above exception, another exception occurred:

我尝试绕过验证过程：

import requests
response = requests.get("https://query1.finance.yahoo.com/v8/finance/chart/META", verify=False)
print(response.status_code)

但是我收到了 429 错误代码：

/Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/urllib3/connectionpool.py:1103: InsecureRequestWarning: Unverified HTTPS request is being made to host 'localhost'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#tls-warnings
  warnings.warn(
429

Answer 1

我通过在下面的调用中在 data.py 中添加 verify = False 来修复它。

response = self._session.get(
            url='https://fc.yahoo.com',
            headers=self.user_agent_headers,
            proxies=proxy,
            timeout=timeout,
            allow_redirects=True,verify = False)

它对我有用。
