了解如何使用http统计信息来了解网站的性能

HTTP状态是一个Python3脚本,用于可视化Web curl(1)统计信息。该脚本写在一个没有依赖性的文件中。本文介绍了有关如何使用http统计信息来了解网站的效果

安装httpstat

如下所示,有两种方法可以在Ubuntu上安装httpstat:

  • 直接下载脚本。

  • 通过Python点

从脚本安装

要从直接脚本安装httpstat,请使用以下命令-

$wget https://raw.githubusercontent.com/reorx/httpstat/master/httpstat.py

样本输出应该像这样-

从Python pip安装

在安装httpstat之前,它应该在Ubuntu上需要一个python-pip软件包。要安装python-pip软件包,请使用以下命令-

$sudo apt install python-pip

样本输出应该像这样-

httpstat的用法

如果通过直接脚本安装了httpstat,请使用以下命令-

$ python httpstat.py nhooo.com

样本输出应该像这样-

通过Python Pip使用httpstat

如果您已通过python pip安装了httpstat,请使用以下命令-

$ httpstat sendfiles.net

样本输出应该像这样-
