使用Python mechanize用txt文件中的文本填充web表单

我试图使用txt文件中的文本用Python mechanize填充web表单，但是当表单填充时，所有返回字符/换行符都会丢失。有没有办法绕过这个问题？当打印到控制台时，它包括返回，所以我有点困惑

def load_message():
the_message = open('ra_message.txt', 'r')
message = the_message.read()
the_message.close()
return message

def message(to_user, subject, the_message):
try:
    br.open(ra_message)
    br.select_form(nr=0)
    br['addrecipient'] = to_user
    br['subject'] = subject
    br['message'] = the_message
    br.submit()
    print('{} succesfully messaged.'.format(to_user))        
    save_line = to_user + ', TRUE\n'
    save_file = open('messaged_users.csv', 'a')
    save_file.write(save_line)
    save_file.close()
except Exception, e:
    print str(e)

def main():
try:
    the_message = load_message()
    login(username, password)
    for name in users:
        message(name, 'Hi {}'.format(name), the_message.format(vote_link))
    print('All users succesfully messaged.')
except Exception, e:
    print str(e)

经过深入研究，我在另一个堆栈溢出线程中找到了答案-

CR=\r LF=\n

HTML表单采用换行符作为CRLF，因此：

\r\n成功了
