linux http代理设置

$ export https_proxy=https://用户名:密码@代理地址:代理端口

如果直接输入 BASH 会报错: bash: !@172.16.2.17: event not found
解决办法 就是将特殊字符转换成 ASIIC 码形式输入, 以 % + Hex 形式(0x忽略).
参考链接: ASCII Reference
比如常见的会出现在密码中的特殊字符:
~ : 0x7E,         ! : 0x21    
@ : 0x40,         # : 0x23  
$ : 0x24,         % : 0x25  
^ : 0x5E,         & : 0x26  
* : 0x2A,         ? : 0x3F   

poet_name = "hp123!@#"
>>> url_code_name = urllib.quote(poet_name)
>>> print url_code_name
hp123%21%40%23

import urllib
user="李白"
user = urllib.quote(user)

passwd="hp123!@#"
passwd = urllib.quote(passwd)

URL = "http://%s:%s@172.10.22.17:8787" % (user,passwd)
print URL
