如何用Python处理POST和GET变量？

假设你正在发布带有以下内容的html表单：

<input type="text" name="username">

如果使用原始

cgi

import cgiform = cgi.FieldStorage()print form["username"]

如果使用

Django，Pylons，Flask

Pyramid

print request.GET['username'] # for GET form methodprint request.POST['username'] # for POST form method

使用

Turbogears，Cherrypy

from cherrypy import requestprint request.params['username']

Web.py

form = web.input()print form.username

Werkzeug

print request.form['username']

如果使用

Cherrypy

Turbogears

def index(self, username):    print username

Google App Engine：

class SomeHandler(webapp2.RequestHandler):    def post(self):        name = self.request.get('username') # this will get the value from the field named username        self.response.write(name) # this will write on the document

因此，你实际上必须选择这些框架之一。
