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！！！

Can vs code run in Windows 8
Apr 15, 2025 pm 07:24 PM
VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.
