Django 与 Flex.
想要开发一个漂亮的网站&＃xff0c;总要一些flash效果滴。这就涉及到django如何与flex打交道。基本的原理是利用pyamf这个中间件&＃xff0c;把django里的request和flex里的actionscript 互相转化。
1. 安装pyamf. 我使用的是0.6.1. 没说的&＃xff0c;老方法&＃xff0c;python manage.py install就安装好了。
2. django端&＃xff08;服务器端&＃xff09;创建方法:
a. 创建amfgateway.py在你的工程根目录下
b. 添加如下内容&＃xff1a;
from pyamf.remoting.gateway.django import DjangoGateway
def say_hello(request, name):
return "hello : %s" % name
usersGateway &＃61; DjangoGateway({
&＃39;my.sayHello&＃39;:say_hello,
})
def say_hello(request, name):
return "hello : %s" % name
usersGateway &＃61; DjangoGateway({
&＃39;my.sayHello&＃39;:say_hello,
})
注意里面的"my", 这会在后面的flex端使用。
c. 修改你的urls.py&＃xff0c;添加 (r&＃39;^my/gateway/&＃39;, &＃39;my.amfgateway.usersGateway&＃39;),
3. Flex端&＃xff1a;
首先创建services-config.xml,添加如下内容&＃xff1a;
xml version&＃61;"1.0" encoding&＃61;"UTF-8"?>
<services-config>
<services>
<service id&＃61;"activeService" class&＃61;"flex.messaging.services.RemotingService" messageTypes&＃61;"flex.messaging.messages.RemotingMessage">
<destination id&＃61;"my">
<channels>
<channel ref&＃61;"myChannel"/>
channels>
<properties>
<source>*source>
properties>
destination>
service>
services>
<channels>
<channel-definition id&＃61;"myChannel" class&＃61;"mx.messaging.channels.AMFChannel">
<endpoint uri&＃61;"http://127.0.0.1:8000/my/gateway/" class&＃61;"flex.messaging.endpoints.AMFEndpoint"/>
channel-definition>
channels>
services-config>
<services-config>
<services>
<service id&＃61;"activeService" class&＃61;"flex.messaging.services.RemotingService" messageTypes&＃61;"flex.messaging.messages.RemotingMessage">
<destination id&＃61;"my">
<channels>
<channel ref&＃61;"myChannel"/>
channels>
<properties>
<source>*source>
properties>
destination>
service>
services>
<channels>
<channel-definition id&＃61;"myChannel" class&＃61;"mx.messaging.channels.AMFChannel">
<endpoint uri&＃61;"http://127.0.0.1:8000/my/gateway/" class&＃61;"flex.messaging.endpoints.AMFEndpoint"/>
channel-definition>
channels>
services-config>
注意destination 的 id属性必须与第二步的my相同。
3. Flex端写一个简单的测试&＃xff1a;

试着运行一下&＃xff1a;
