Python请求获取SSLerror

Question

尝试使用Requests会话发出一个简单的get请求，但是我一直在获取特定网站的SSLerror。我认为问题可能出在网站上（我使用https://www.ssllabs.com进行了扫描，结果下降了），但是我不确定，因为我对该领域一无所知:)我想了解发生了什么。

一个解决方案/解释将是巨大的，谢谢！

编码：

import requests

requests.get('https://www.reporo.com/')

我收到下一个错误：

SSLError: [Errno bad handshake] [('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')]

我在https://www.ssllabs.com上进行了扫描，结果如下：

Answer 1

www.reporo.com的证书本身（不是reporo.com）有效，但是缺少链证书，如ssllabs的报告所示：

Chain issues    Incomplete
....
2   Extra download  Thawte DV SSL CA 
Fingerprint: 3ca958f3e7d6837e1c1acf8b0f6a2e6d487d6762

要点是“未完成”和“额外下载”。一些浏览器将缓存缺少的链证书，其他浏览器将进行下载，而其他浏览器将失败。如果您尝试使用新的Firefox配置文件（该站点没有缓存任何证书）尝试该站点，它也会失败。

您可以下载缺少的链证书，并将其用作带有verify请求参数的受信任CA证书。不要只禁用验证，因为这样您就容易受到中间人攻击。

分步说明：

• 从https://ssl-tools.net/certificates/vqgvhb-thawte-dv-ssl-ca下载丢失的证书（通过搜索SSLLabs报告中给出的指纹找到该证书）。以PEM格式下载文件，即https://ssl-tools.net/certificates/3ca958f3e7d6837e1c1acf8b0f6a2e6d487d6762.pem。
• 从https://ssl-tools.net/certificates/91c6d6ee3e8ac86384e548c299295c756c817b81.pem下载根证书（也可通过搜索指纹找到）。
• 将两个文件合并到一个新文件中chain.pem。确保每个文件都以有效的行尾字符结尾（不是下载的）。结果文件应如下所示。
• 修改通话至

  requests.get('https://www.reporo.com/', verify = 'chain.pem')
