GitHub上排名第一的python开源项目名叫HTTPie，它的描述为：HTTPie is a command line HTTP client, a user-friendly cURL replacement，看样子跟cURL的功能类似，之前有项目是通过python脚本调用cURL将磁盘中存储的JSON数据通过HTTP POST的方式发送给各个接收端来分别进行解析，处理并展示，既然是比较火的开源项目，这玩意应该挺好用

1：从TAG里下载一个版本

https://github.com/jakubroztocil/httpie/tree/0.9.2

2：安装

官方写的是可以通过apt-get，yum，或者pip直接进行安装，我好折腾，喜欢直接编译源代码瞧瞧各种依赖关系

[lihui@localhost httpie-0.9.2]$ sudo python setup.py install

结果会卡在一个在线Download的依赖

 

Installed /usr/lib/python2.6/site-packages/argparse-1.3.0-py2.6.egg
Searching for Pygments>=1.5
Reading http://pypi.python.org/simple/Pygments/
Best match: Pygments 2.0.2

在线Downloading半天没动静，直接wget这个URL，果真找不到，由于是VPN连到服务器，也不清楚是啥网络问题，直接本地PC可以下载这个包，传过去，先安装Pygments

[lihui@localhost Pygments-2.0.2]$ sudo python setup.py install

安装完成之后，再次安装httpie，看是否还存在依赖，再次出现一个依赖，不过貌似很小，很快就结束

Adding requests 2.7.0 to easy-install.pth file

安装完之后，可以找到

[lihui@localhost httpie-0.9.2]$ which http
/usr/bin/http

3：实验

（1）开启tcpdump抓包

[lihui@localhost ~]$ sudo tcpdump -i eth0 port 80 -vv -w baidu.pcap

（2）执行httpie，随便来个GET试试

[lihui@localhost httpie-0.9.2]$ http -f GET baidu.com
HTTP/1.1 200 OK
Accept-Ranges: bytes
Cache-Control: max-age=86400
Connection: Keep-Alive
Content-Length: 81
Content-Type: text/html

（3）解析一下抓获的数据包，可以解析到HOST

[lihui@localhost ~]$ tshark -r baidu.pcap -T fields -e http.host -e http.request.method | sed '/^\s*$/d'
baidu.com        GET

除此之外，选项貌似还看到了JSON

[lihui@localhost httpie-0.9.2]$ http -dasdfs
usage: http [--json] [--form] [--pretty {all,colors,format,none}]
            [--style STYLE] [--print WHAT] [--verbose] [--headers] [--body]

            [--session SESSION_NAME_OR_PATH]
            [--session-read-only SESSION_NAME_OR_PATH] [--auth USER[:PASS]]
            [--auth-type {basic,digest}] [--proxy PROTOCOL:PROXY_URL]

            [--timeout SECONDS] [--check-status] [--ignore-stdin] [--help]
            [--version] [--traceback] [--debug]
            [METHOD] URL [REQUEST_ITEM [REQUEST_ITEM ...]]

可以分别尝试下含义
