在Mac电脑上利用bottle搭建简单web服务器，以实现mac版本的网络调试助手。
主程序从csdn下载，下载地址为：http://download.csdn.net/detail/yuanhuamanjing/9383142，推测为win运行环境。调试后的服务器程序main.py如下：

该错误的原因是/etc/hostname文件写的hostname 没有写在/etc/hosts里， 加上就好了 。 比如添加 “127.0.0.1 myname” 到hosts最后一行， 即可。
socket.gethostname()读取/etc/hostname中的name； socket.gethostbyname(name)是通过name来提取/etc/hosts里和name对应的ip 。如果hosts里没有对应的name，肯定就要抛出错误。
因此前往/etc文件夹，发现本机无hostname文件，有hosts文件。将hosts文件备份（重要事情说三遍：务必牢记修改系统文件前必须备份，以免发生意外！务必牢记修改系统文件前必须备份，以免发生意外！务必牢记修改系统文件前必须备份，以免发生意外！）打开新的hosts文件，发现hosts文件内容仅有一行localhost记录：
127.0.0.1 localhost
在终端内打开python模式，利用如下代码查询本机hostname，这里举例为“xxMacBookPro.local”：
import socket
socket.gethostname()注：本机hostname的另一种查看方式是在系统偏好设置内，选择共享选项即可，如下图：
添加hosts文件内容如下：
127.0.0.1 localhost
127.0.0.1 xxMacBookPro.local
127.0.0.1 xxMacBookPro扫描二维码关注公众号，回复： 4686908 查看本文章
再此运行程序即可成功启动web服务器。
附修改后的运行文件（去除bootstrap.min.css等内容，提高网页加载速度），下载地址为http://download.csdn.net/detail/qiaokelinaicha/9803586：
1. main.py
2. index.html
3. main.html
文件运行顺序为：
1.运行main.py，启动本地web服务器，主页地址为http://localhost:8081/，网页自动跳转至index.html；
2.选择相应的运行模式，tcp服务器模式时输入本机服务器ip地址和端口号；tcp客户端模式时输入监听服务器ip地址和端口号；udp模式与tcp模式对应。选择“开始监听”按钮并成功建立socket后，网页跳转至main.html，自动接收消息，也可按需发送自定义消息。
