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！！！
