python代码简单模拟Java中的MVC设计
包括两个文件：
一、 mymvc.py
import tornado.ioloop
import tornado.web
#访问地址 http://127.0.0.1:9870/main?ywdm=06&num1=10&num2=200
class TestClassA:
def sub(self,a,b):
return a-b
def add(self,a,b):
return a+b
def chen(self,a,b):
return a*b
class TestClassB:
def sub(self,a,b):
return a-b
def add(self,a,b):
return a+b
def chen(self,a,b):
return a*b
sys_config={}
sys_config["01"]=['mymvc','TestClassA','add']
sys_config["02"]=['mymvc','TestClassA','sub']
sys_config["03"]=['mymvc','TestClassA','chen']
sys_config["04"]=['mymvc','TestClassB','add']
sys_config["05"]=['mymvc','TestClassB','sub']
sys_config["06"]=['mymvc','TestClassB','chen']
class MainHandler(tornado.web.RequestHandler):
def get(self):
ywdm=self.get_argument('ywdm')
num1=int(self.get_argument('num1').encode('utf-8'))
num2=int(self.get_argument('num2').encode('utf-8'))
message="hello !"
print type(num2)
if ywdm in sys_config:
my_module_name=sys_config[ywdm][0]
my_class_name=sys_config[ywdm][1]
my_method_name=sys_config[ywdm][2]
my_module = __import__(my_module_name)
my_class = getattr(my_module,my_class_name)
my_obj = my_class()
my_method = getattr(my_obj,my_method_name)
ret=my_method(num1,num2)
print "ret:",ret
#message = "ret data:::"+ret
message="ywdm:"+ywdm+"-data:"+str(ret)
items = ["Item 1", "Item 2", "Item 3"]
self.render("test.html", title="My title", items=items,config_items=sys_config)
#self.write(message)
#self.finish()
application = tornado.web.Application([(r"/main", MainHandler),])
if __name__ == "__main__":
application.listen(9870)
tornado.ioloop.IOLoop.instance().start()
二、页面模板html： test.html
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<ul>
{% for item in items %}
<li>{{ escape(item) }}</li>
{% end %}
</ul>
<ul>
{% for item in config_items %}
<li>{{ escape(config_items[item][0]) }}
-{{ escape(config_items[item][1]) }}
-{{ escape(config_items[item][2]) }}
</li>
{% end %}
</ul>
</body>
</html>
执行： mymvc.py
然后浏览器输入：http://127.0.0.1:9870/main?ywdm=06&num1=10&num2=200
返回如下：
- Item 1
- Item 2
- Item 3
- mymvc -TestClassA -sub
- mymvc -TestClassA -chen
- mymvc -TestClassA -add
- mymvc -TestClassB -chen
- mymvc -TestClassB -add
- mymvc -TestClassB -sub
