web.py

http://webpy.org/

import web
        
urls = (
    #把所有/(.*)的网址都交给hello这个类处理，url和处理类成对出现
    '/(.*)', 'hello'
)
app = web.application(urls, globals())

class hello:        
    def GET(self, name):
        if not name: 
            name = 'World'
        return 'Hello, ' + name + '!'

if __name__ == "__main__":
    app.run()

我就发现python的框架用起来这么简单呢

而且测试方便

todo-list的例子

另外，关于web.py模板的中文说明

http://webpy.org/docs/0.3/templetor.zh-cn

仿照写的小例子

code.py

import web
urls = (
    '/', 'index'
)
render = web.template.render('templates/')
class index:
    def GET(self):
        return render.first('world','name')
if __name__ == "__main__":
    app = web.application(urls, globals())
   
    app.run()

templates\first.html

$def with (name1,name2)
<html><head>
<title>my si

</title>
</head><body>
Hello $name1 , hello $name2!
<table>
$for c in ["a", "b", "c", "d"]:
    <tr class="$loop.parity">
        <td>$loop.index</td>
        <td>$c</td>
    </tr>
</table>  
</body></html>

关于loop的东西还没细看，想来也是struts里面标签那一套。。。。

看到form了，不过发现官网上的代码，经常是直接copy过来不能运行的

譬如也不说说怎么import的

譬如form.Textbox的大写T竟然成了小写，害我看了半天

话又说回来，这种解析form成table的方式，还真是比较纯后台呢，现在谁还用这个table？就只有一个好处--简单

当然，偷懒者也适用，哎呀，我又想起了我半途而废的css

最简单的官网的例子

import web
from web import form as form
urls = (
    '/', 'index'
)
render = web.template.render('templates/')

login = form.Form(
      form.Textbox('username'),
      form.Password('password'),
      form.Button('Login'),
   )
class index:
    def GET(self):
        #return render.first('world','name')
        f = login()
        return f.render()
if __name__ == "__main__":
    app = web.application(urls, globals())
   
    app.run()

用了多个属性的官网例子

import web
from web import form as form
urls = (
    '/', 'index'
)
render = web.template.render('templates/')

login = form.Form(
    form.Textbox("firstname",
     form.notnull, #put validators first followed by optional attributes
     class_="textEntry", #gives a class name to the text box -- note the underscore
     pre="pre", #directly before the text box
     post="post", #directly after the text box
     description="please enter your name", #describes field, defaults to form name ("firstname")
     value="bob", #default value
     id="nameid", #specify the id
	 ),
	 form.Textbox('phonenumber',
        size="12",
        maxlength="12"
     ), 
)
class index:
    def GET(self):
        #return render.first('world','name')
        f = login()
        return f.render()
if __name__ == "__main__":
    app = web.application(urls, globals())
   
    app.run()

如何接受form的post数据，web.input和web.data

code.py

import web
from web import form as form
urls = (
    '/', 'index',
	'/add','add'
)
render = web.template.render('templates/')
class index:
    def GET(self):
        return render.post()
class add:
    def POST(self):	    
		print web.input()['title1']
		print web.data()
		raise web.seeother('/')
       	
if __name__ == "__main__":
    app = web.application(urls, globals())
    app.run()

templates/post.html

<html><head>
<title>post test

</title>
</head><body>
<form method="post" action="add">
<input type="text" name="title" /> 
<input type="text" name="title1" /> 
<input type="text" name="title2" /> 
<input type="text" name="title3" /> 
<input type="submit" value="Add" />
</form>

</body></html>
