通过PyFetion可以使用python用飞信发送短信。
例子：
from fetion import *
import os
def SendSMS(sms):
myphone = 'xxxxxx'
mypwd = 'oooooooooo'
tophone = 'oxoxoxoxoxox'
fetion = PyFetion(myphone,mypwd,'TCP')
fetion.login(FetionHidden)
print 'send to '+tophone
fetion.send_sms(sms,tophone,True)
print 'OK'
fetion.logout()
return True
msg = "hello world"
SendSMS(msg)
print 'OK!!!'
有时会提醒输入验证码，验证码就在PyFetion生成的一个图片中，查看图片，然后输入验证码即可。
