使用Bash确定URL是HTTP还是HTTPS [英] Using Bash to determine if URL is HTTP or HTTPS

问题描述

在bash中是否可以确定URL是否使用SSL?在将其他任何内容发送到URL之前，我想知道它是否仅接受HTTP或HTTPS连接.

Is there a way In bash to determine if a URL uses SSL? Before I send anything else to the URL I want to find out if it only accepts HTTP or HTTPS connections.

推荐答案

如果有权访问wget，则可以使用以下脚本.

You can use the below script if you have access to wget.

#/bin/bash    
URL=google.com
if wget --spider https://$URL 2>/dev/null; then
  echo "https is present"
else
  echo "https not present"
fi

请注意，您需要设置http_proxy/https_proxy.

Please note that you need to have http_proxy / https_proxy set.

我在cygwin64中测试了上面的脚本[目前无法访问nix系统]

I tested the above script in cygwin64 [dont have access to nix system as of now]

您还应该能够使用curl修改相同的脚本.

You should be also able to modify the same script using curl.
