speedtest-cli--外网的上传/下载速率测试

• speedtest-cli是一个使用python编写的命令行脚本，通过调用speedtest.net测试上下行的接口来完成速度测试

ubuntu下安装

zw@zw-pc:apt-get install speedtest-cli
zw@zw-pc:speedtest-cli -h

                     [--csv-header] [--json] [--list] [--server SERVER]
                     [--exclude EXCLUDE] [--mini MINI] [--source SOURCE]

  --no-upload           Do not perform upload test
  --bytes               Display values in bytes instead of bits. Does not
                        affect the image generated by --share, nor output from
                        --json or --csv
  --share               Generate and provide a URL to the speedtest.net share
                        results image, not displayed with --csv
  --simple              Suppress verbose output, only show basic information
  --csv                 Suppress verbose output, only show basic information
                        in CSV format. Speeds listed in bit/s and not affected
                        by --bytes
  --csv-delimiter CSV_DELIMITER
                        Single character delimiter to use in CSV output.

  --json                Suppress verbose output, only show basic information
                        in JSON format. Speeds listed in bit/s and not
                        affected by --bytes
  --list                Display a list of speedtest.net servers sorted by
                        distance
  --server SERVER       Specify a server ID to test against. Can be supplied
                        multiple times

  --no-pre-allocate     Do not pre allocate upload data. Pre allocation is
                        enabled by default to improve upload performance. To
