curl 是一个功能非常强大的开源软件,支持FTP,HTTP,HTTPS,Telnet等多种协议。对于运维、开发同学来说，它是工作中不可缺少的排障利器。它的基本使用姿势请参考文档https://cloud.tencent.com/developer/article/1419809

今天主要给大家介绍curl 的高级使用姿势：

[root@cdntest home]# curl -w "@curl-format" -o /dev/null  -sL "http://cloud.tencent.com/"
    time_namelookup:  0.004
       time_connect:  0.037
    time_appconnect:  0.144
   time_pretransfer:  0.144
      time_redirect:  0.124
 time_starttransfer:  0.222
 --------------------------
         time_total:  0.545
          http_code:  200
         ------------------
      size_download:  348734
     speed_download:  639889.000
        size_header:  692
       size_request:  162
        size_upload:  0
       speed_upload:  0.000

curl-format 内容如下：

[root@cdntest home]# more curl-format
