Python的请求模块异常SSLError

Question

我得到一个请求模块异常错误，当我尝试访问的网站http://www.acastipharma.com/。所以我相信这是一个网站的具体问题，我没有与任何其他网站的问题。下面是一些示例代码

import requests
initialURL = 'http://www.acastipharma.com/'
r = requests.get(initialURL)

当我运行这段代码，我得到的是与终止的错误信息

requests.exceptions.SSLError: HTTPSConnectionPool(host='www.acastipharma.com', port=443): Max retries exceeded with url: /investors/ (Caused by SSLError(SSLError(1, '[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:645)'),))

互联网搜索表明该问题可能与acastipharma的SSL证书。我尝试安装pyopenssl，以确保我有最新版本的模块那检查SSL证书，但没有解决问题。我也试着运行与验证= False选项的requests.get声明但这也是不成功的。

r = requests.get(initialURL, verify=False)

如果有人有关于如何解决此问题的任何想法，我将不胜感激帮助。我使用的是旧urllib.request里包也试过，但遇到了同样的错误。

这是一个更新到我原来的问题：我张贴的错误信息是由试图在acastipharma网站子页面的一个运行请求命令，这里是完整的错误消息时，我正好运行代码如图这个问题，我得到：

我使用Python 3.5.1。我在Mac上使用高塞拉利昂版本10.13.2。我使用的要求2.18.4。由于发布的问题，我认为，问题出在我的IDE PyCharm的环境。如果用我的Python 3.5的环境我有问题，显示在此问题，如果我切换项目解释为Python 3.6蟒蛇环境要求将工作，但不幸的是，MySQL将不会导入。谢谢

Answer 1

OpenSSL的版本是OpenSSL的0.9.8zh 2016年1月14日

这（很旧，不支持长）版本的OpenSSL不支持特定的Web服务器所需的新密码。此服务器只支持ECDHE密钥交换，这不是由OpenSSL的0.9.8版本支持呢。这意味着，客户端只提供密码给该服务器将不接受，并且由于没有共同的密码，服务器将关闭与SSL握手警报连接的服务器。

我们可以使用下面的忽略这个SSL错误：

import warnings
from urllib3.exceptions import  InsecureRequestWarning
warnings.simplefilter('ignore',InsecureRequestWarning)
