ssl - Wget 因证书错误而失败

Question

作为自动构建的一部分，我们运行从 github 下载一些代码。最小示例:

wget github.com

最近，该命令开始因证书错误而失败:

URL transformed to HTTPS due to an HSTS policy
--2017-10-05 11:43:45--  https://github.com/
Resolving github.com (github.com)... 192.30.253.112, 192.30.253.113
Connecting to github.com (github.com)|192.30.253.112|:443... connected.

ERROR: cannot verify github.com's certificate, issued by 'CN=DigiCert SHA2 Extended Validation Server CA,OU=www.digicert.com,O=DigiCert Inc,C=US':
  Unable to locally verify the issuer's authority.

我尝试更新证书存储和 wget 本身:

update-ca-certificates
apt-get install wget

错误还是一样。我的wget版本是GNU Wget 1.17.1，操作系统是Ubuntu 16.04.3。

Answer 1

您可以在 wget 命令行中添加 --no-check-certificate 选项来避免检查证书的有效性。
