Python的Bottle框架中实现最基本的get和post的方法的教程

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usernamepassword)(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,
 '
username= '+username,
 '
password= '+password) # test
 
 if check_login(username, password):
 return "
 Your login information was correct.
"
 else:
 return "
Login failed. 
"
 else:
 return ''' 
 '''

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 ''' 
 '''

@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 "
 Your login information was correct.
"
 else:
 return "
Login failed. 
"

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！！！
