Server Can'；t使用wget验证url证书（没有根访问权限）

我在远程服务器上，我们没有sudo访问权限。我有一个脚本可以帮助从这个url下载数据：wget

代码：

但是我得到了一个错误：

--2021-04-30 02:04:31--  http://wget/

现在，我不是证书工作原理方面的专家，我阅读了另一篇stackoverflow文章来检查证书错误，并在这里查找名为

额外下载的内容：我不知道如何阅读此网站，但我没有看到任何错误

如何解决证书错误并运行shell脚本？
datashare.is.ed.ac.uk（至少对于您的URL）重定向到datashare.ed.ac.uk，正如错误消息所示，是后者发生了错误。显示“链问题不完整”和所需的“额外下载”。为您找到它，或者因为前一个站点提供了它，您可以在上面使用
openssl s_client-showcerts
。附：这不是一个真正的编程问题。@dave_thompson_085我不太了解证书是如何工作的，如果不是这样问的话，我深表歉意。但是，如果我可以问一下，如何使用
openssl s\u-clent-showcerts
。它会像
wget-P'data/cinic'wget一样吗https://datashare.is.ed.ac.uk/bitstream/handle/10283/3192/CINIC-10.tar.gz openssl s_clent-showcerts
？@dave_thompson_085另一个问题：whatsmychaincert.com/？datashare.ed.ac.uk中的链接单击时显示要下载的文件。如何将其用作带有
wget
的url？
