Foundations of Python Network Programming - 读书笔记系列(3) - Email Services

Email Services这一章因为用的不多，因此大致过了一下，现在仔细看到后来会忘掉一大半。因此，到时候用到再看也不迟，这里先给个简单的例子：

import  smtplib

def  readManyLines():
     """ Read lines from the user until they enter a line with a single
period, and return a single string. """
    result  =   ""
     while   1 :
        line  =  raw_input()
         if  line  ==   ' . ' :  return  result
        result  =  result  +  line  +   " \n "

servername = raw_input( " SMTP server name:  " )
Fromaddress = raw_input( " From address:  " )
Toaddress = raw_input( " To address:  " )
print   " Enter your message. To end, enter a line that begins with a "
print   " period and has no other characters:  "
MessageText = readManyLines()
server = smtplib.SMTP(servername)
server.sendmail(Fromaddress, Toaddress, MessageText)
server.quit()
