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！！！
