无法通过ippython向SOAP发送https获取请求。

Question

这可能是一个比python更重要的安全问题，但我们开始吧。

我想用这个网址从一个web服务中获取数据。https:/x.x.x.xserviceWSserver.php?wsdl。. 他们给我寄来了密钥、CRT和PEM文件，但我不能让它工作。到目前为止，我有这个代码，

import requests
crt = '/path/to/crt'
key = '/path/to/key'
pem = '/path/to/pem'
body = '<soap>...</soap>'

res = requests.get(ws, cert=(crt, key), verify=pem)

但它却给我这个错误

我猜测是因为证书是针对一个域名的，比如： "*.remoteework.com.pe",而我正试图连接到一个IP上. 如果这是问题所在，那么在他们放上正确的域名之前，代码将永远无法工作，对吗？

任何帮助将是很好的!

最后，我得到了解决方案，下面的评论。

正如Patrick所说 "你总是在最后连接到一个IP，但你确实需要传递一个名字给为你连接的库，因为事实上，任何一个体面的库都必须将给出的主机名与证书中的内容进行比较"。目标主机是未知的。我修改了 etchosts 文件，写上ip和证书的名称，就成功了。

非常感谢！！。
