Python的Bottle框架中实现最基本的get和post的方法的教程

1、GET方式：
  

# -*- coding: utf-8 -*-
#!/usr/bin/python
# filename: GETPOST_test.py
# codedtime: 2014-9-20 19:07:04


import bottle

def check_login(username, password):
  if username == '123' and password == '234':
    return True
  else:
    return False

@bottle.route('/login')
def login():
  if bottle.request.GET.get('do_submit','').strip(): #点击登录按钮
    # 第一种方式(latin1编码)
##    username = bottle.request.GET.get('username','').strip() # 用户名
##    password = bottle.request.GET.get('password','').strip() # 密码

    #第二种方式(获取username\password)(latin1编码)
    getValue = bottle.request.query_string
##    username = bottle.request.query['username'] # An utf8 string provisionally decoded as ISO-8859-1 by the server
##    password = bottle.request.query['password'] # 注：ISO-8859-1(即aka latin1编码)
    #第三种方式(获取UTF-8编码)
    username = bottle.request.query.username   # The same string correctly re-encoded as utf8 by bottle
    password = bottle.request.query.password   # The same string correctly re-encoded as utf8 by bottle
    
    print('getValue= '+getValue,
       '\r\nusername= '+username,
       '\r\npassword= '+password) # test
    
    if check_login(username, password):
      return "<p> Your login information was correct.</p>"
    else:
      return "<p>Login failed. </p>"
  else:
    return ''' <form action="/login" method="get">
           Username: <input name="username" type="text" />
           Password: <input name="password" type="password" />
           <input value="Login" name="do_submit" type="submit">
          </form>
        '''

bottle.run(host='localhost', port=8083)

这里注意说一下Bottle编码的问题，只有第三种方式会将我们输入的字符如果是UTF-8重新编码为UTF-8,当你的内容里有中文或其他非英文字符时，这种方式就显的尤为重要。

运行效果如下：

2、POST方式：

# -*- coding: utf-8 -*-
#!/usr/bin/python
# filename: GETPOST_test.py
# codedtime: 2014-9-20 19:07:04


import bottle

def check_login(username, password):
  if username == '123' and password == '234':
    return True
  else:
    return False

@bottle.route('/login')
def login():
  return ''' <form action="/login" method="post">
         Username: <input name="username" type="text" />
         Password: <input name="password" type="password" />
         <input value="Login" type="submit">
        </form>
      '''

@bottle.route('/login', method='POST')
def do_login():
  # 第一种方式
#  username = request.forms.get('username')
#  password = request.forms.get('password')

  #第二种方式
  postValue = bottle.request.POST.decode('utf-8')
  username = bottle.request.POST.get('username')
  password = bottle.request.POST.get('password')

  
  if check_login(username, password):
    return "<p> Your login information was correct.</p>"
  else:
    return "<p>Login failed. </p>"

bottle.run(host='localhost', port=8083)

登录网站、提交文章、评论等我们一般都会用POST方式而非GET方式，那么类似于第二种方式的编码就很用用处，能够正确的处理我们在Form中提交的内容。而第一种则可能会出现传说中的乱码问题，谨记！！！
