httpstat一个实用的网络工具

概述

这个工具可以收集一些网站的基础信息，而且它使用ascii字符的方式显示网站各种连接的时间，方便我们根据这个去优化网站，从而提高网站的连接响应速度。

安装

安装很简单，使用pip就可以完成
pip install httpstat

使用

一般来说都是httpstat加上你的网站名字，比如

  ~ httpstat http://www.baidu.com/

    namelookup:12ms           |                   |                  |
                        connect:49ms              |                  |
                                      starttransfer:88ms             |
                                                                 total:88ms   

上面显示了dns查找花了12ms，tcp连接花了37ms，服务器处理用了38ms，内容传输花了0ms，而且可以看到服务器的类型等等，这个工具还可以设置环境变量来控制显示的信息

Environments:
  HTTPSTAT_SHOW_BODY    Set to `true` to show resposne body in the output,
                        note that body length is limited to 1023 bytes, will be
                        truncated if exceeds. Default is `false`.
  HTTPSTAT_SHOW_IP      By default httpstat shows remote and local IP/port address.
                        Set to `false` to disable this feature. Default is `true`.
  HTTPSTAT_SHOW_SPEED   Set to `true` to show download and upload speed.
                        Default is `false`.
  HTTPSTAT_SAVE_BODY    By default httpstat stores body in a tmp file,
                        set to `false` to disable this feature. Default is `true`
  HTTPSTAT_CURL_BIN     Indicate the curl bin path to use. Default is `curl`
                        from current shell $PATH.
  HTTPSTAT_DEBUG        Set to `true` to see debugging logs. Default is `false`

如果你要临时让这个工具不显示比如网站的ip，只要在终端输入
export HTTPSTAT_SHOW_IP=false
之后你就不会看到ip了，和第一次输出你可以对比一下

其实这个工具是对curl的封装，所以有的curl参数对这个工具也是适用的
