    wget -c -m -k -np -p -E -U Mozilla --no-check-certificate http://www.xx.com/
 
 2.当遇到OpenSSL错误的时候
   OpenSSL: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

  wget -c -m -k -np -p -E -U Mozilla --secure-protocol=TLSv1_2 --no-check-certificate  https://www.xx.com/



备注
你还可以从Wayback machine下载镜像
One way to do that would be literally downloading the website using HTTrack or wget.

You can also remove the Wayback machine banner on top by using a different url. 
Instead of e.g. 'http://web.archive.org/web/20190302232807/http://example.com/', 
you can use 'http://web.archive.org/web/20190302232807id_/http://example.com/', note the id_ after the timestamp number.
