FluorineFx的配置

使用“FluorineFx Asp.net Web site”向导生成的项目结构如下:

除了编写.net服务器端代码,Flex客户端代码。还有非常重要的就是正确的设置配置文件。配置文件将指导如何将客户端的请求重定向到正确的服务器对象(代码中体现不出来)。

打开项目根目录下的web.config。系统向导默认的配置与fluorinefx相关的部分(其他的省略了)如下:

<?xml version="1.0" encoding="utf-8" ?>

  ...

</configuration>  

说明:其中,<fluorinefx />部分不是必须有的 ;<httpModules />中的"FluorineGateway" http module entry 必须有;如果没有使用services-config.xml配置文件,才需要设置<security />部分。

除了根目录下的web.config文件(asp.net网站的标准配置文件外),WEB-INF/flex目录下还有四个配置文件(.xml)。

由于FluorineFxFlex Data Service.net替代品(如果你用Java写服务器端程序,则可以直接用Flex Data Service),FluorineFx提供了和Flex Data Service相同的功能即在services-config.xml配置文件的<services>部分配置Remoting Service, Message Service Data Management Service

此外,除了把所有配置都放在services-config.xml一个文件中,还可以把Service配置信息分散到多个配置文件里,然后包含进来以达到简化的效果。如下:

  <services>
    <!-- Remoting Service -->
    <service-include file-path="remoting-config.xml"/>
    <!-- Message Service -->
    <service-include file-path="messaging-config.xml"/>
    <!-- Data Management Service -->
    <service-include file-path="data-management-config.xml"/>
  </services>

下表是这四个配置文件的作用:

services-config.xml

顶层的配置文件。包含有 Contains security constraint 定义, channel 定义, service 定义。

remoting-config.xml

Remoting Service destination定义,用于访问remote objects

messaging-config.xml

Message Service destination定义,用于publish subscribe messaging

data-management-config.xml

Data Management Service destination定义。

看上去这些配置文件和Flex Data Service保持一致。没错,FluorineFx 配置文件与Flex/Flash保持了统一。

这四个XML格式的配置文件中可以使用的XML elements如下表:

XML element

在这些配置部分,有些针对于所有的全部的Service(在services-config.xml设置),有些则专用于特定的Service(在remoting-config.xml/ messaging-config.xml/ data-management-config.xml中设置)。

先看看services-config.xml中的全局设置部分:

1.配置message channel

FluorineFx 使用Flex messaging system 中的message channel传输消息。一个channel可以让多个Service通信。FluorineFx目前不支持AMF polling channels 。在services-config.xml配置文件中可以设置AMF Channel 或者RTMP Channel。如下:

<channels>

  <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel">

<endpoint uri="http://{server.name}:{server.port}/{context.root}/Gateway.aspx"

 class="flex.messaging.endpoints.AMFEndpoint"/>

  </channel-definition>

  <channel-definition id="my-rtmp" class="mx.messaging.channels.RTMPChannel">

       <endpoint uri="rtmp://{server.name}:1951"    class="flex.messaging.endpoints.RTMPEndpoint"/>

  </channel-definition>

</channels>

这里用<channel-definition>定义的channel,每个都有唯一的id<endpoint>uri设置的是一个接受用户请求的网关(Gateway.aspx)程序。打开这个网关程序,你可以发现程序中没有任何代码。

Flex调用远程对象的流程大概如下:

<!--[if !supportLists]-->l         <!--[endif]-->Flex发出调用远程对象的请求,这个请求会被Flash Player编码成AMF

<!--[if !supportLists]-->l         <!--[endif]-->Flex代码中定义了 Service组件,通过该组件的id,找到对应配置文件中定义的destination

<!--[if !supportLists]-->l         <!--[endif]-->destination通过它的channel id找到对应的channel定义。

<!--[if !supportLists]-->l         <!--[endif]-->根据channel的定义,将请求发送给指定的gateway

<!--[if !supportLists]-->l         <!--[endif]-->gateway将请求发送给gateway的后台类,将消息转换成.net格式,调用服务器上正确的类;

接下来,针对Remoting Service, Message Service Data Management Service的配置分别进行详细说明。

 


一、配置RPC(remoting-config.xml)

定义Remoting Service destination就是定义需要访问的remote objectRemoting service destination就是一个对象,Flex使用<mx:RemoteObject> ActionScript代码连接这个远程对象。

例如:

<service id="remoting-service" class="flex.messaging.services.RemotingService" messageTypes="flex.messaging.messages.RemotingMessage">
<!-- Adapter 定义不是必须的,  gateway 会自动的创建它-->
<adapters>
    <adapter id="dotnet" class="FluorineFx.Remoting.RemotingAdapter" default="true"/>
</adapters>
<default-channels>
    <channel ref="my-amf"/>
</default-channels>
<!—下面定义一个Destination,也就是一个远程对象 -->
<destination id="EchoServiceRO">
<!--  由于上面定义了一个默认的channel,则不需要再定义channel
  <channels>
     <channel ref="my-amf"/>
  </channels>
-->  
  <properties>
    <source>ServiceLibrary.EchoService</source>
    <!-- <scope>application</scope> -->
  </properties>
  <security>
    <security-constraint ref="privileged-users"/>
  </security>
</destination>
 
...
<security>
    <security-constraint id="privileged-users">
        <auth-method>Custom</auth-method>
        <roles>
            <role>privilegedusers</role> 
            <role>admins</role>
        </roles> 
    </security-constraint>
</security>
... 

对上面配置的说明:

1<security>的安全设置

定义了远程对象,可以使用security constraint来限制用户访问访问这个destination (只支持custom authentication)

Security constraints 可以在destination中定义,也可以在destination外面 定义,然后在destination中通过Security constraints id引用。

2Destination adapter

Adapters是服务器上的一个组件,利用Adapter,客户端才能访问远程服务器上的 service object Adapter 定义不是必需的, gateway 将自动配置它。默认的Remoting Adapterflex.messaging.services.RemotingService

3Remote object <properties>

Property element

描述

source

Fully qualified type name of the .NET object (remoting service)

scope

可以设置为 request application  session。默认值为“ request”。

如果为“request”,则Objects是无状态的stateless (  remoting service object is instantiated for every request);如果为“application”,则整个application都可以访问这个object

如果为“session”,则相同的session可以使用 (a single remoting service object is created per asp.net session).

4Web service properties(还不支持)

Property element

描述

wsdl

不支持

soap

不支持

5.默认设置

如果没有service配置文件,则gateway会使用下面的默认配置:

<?xml version="1.0" encoding="UTF-8"?>

<factories>

   <factory id="dotnet" class="FluorineFx.Messaging.DotNetFactory"/>

</factories>

<services-config>

    <services>

       <service id="remoting-service" class="flex.messaging.services.RemotingService" messageTypes="flex.messaging.messages.RemotingMessage">

           <!--  所有的远程调用remote calls 都被路由到这个destination-->

           <destination id="fluorine">

               <channels>

                   <channel ref="my-amf"/>

               </channels>

               <properties>

                   <source>*</source>

               </properties>

           </destination>

      <!--  只有在Service Browsing打开的情况下,下面的destination才创建 -->      

    <!--  This destination is created only when Service Browsing is enabled-->

           <destination id="FluorineFx.ServiceBrowser.FluorineServiceBrowser">

               <channels>

                   <channel ref="my-amf"/>

               </channels>

               <properties>

                   <source>FluorineFx.ServiceBrowser.FluorineServiceBrowser</source>

               </properties>

           </destination>

           <!-- This destination is created only when Service Browsing is enabled-->

           <destination id="FluorineFx.ServiceBrowser.ManagementService">

               <channels>

                   <channel ref="my-amf"/>

               </channels>

               <properties>

                   <source>FluorineFx.ServiceBrowser.ManagementService</source>

               </properties>

           </destination>

           <!-- This destination is created only when Service Browsing is enabled-->

           <destination id="FluorineFx.ServiceBrowser.CodeGeneratorService">

               <channels>

                   <channel ref="my-amf"/>

               </channels>

               <properties>

                   <source>FluorineFx.ServiceBrowser.CodeGeneratorService</source>

               </properties>

           </destination>

       </service>

 

   </services>

 

   <!-- This is the LoginCommand specified in the web-config file if applicable-->

   <security>

      <login-command class="..." server="asp.net"/>

   </security>

 

   <channels>

        <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel">

            <endpoint uri="http://{server.name}:{server.port}/{context.root}/Gateway.aspx" class="flex.messaging.endpoints.AMFEndpoint"/>

        </channel-definition>

   </channels>

</services-config>

 


二、配置 Message Service

Message Service destination 是就是消息传输的终端(endpoint)。在这台终端机上封装有服务器端代码,处理传输过来的消息 。使用 Producer Consumer 组件或ActionScript API可以连接到message service destination

例如:

<service id="message-service" class="flex.messaging.services.MessageService" messageTypes="flex.messaging.messages.AsyncMessage">
<adapters>
    <adapter id="chat" class="ServiceLibrary.ChatAdapter" default="true"/>
</adapters>
 
<destination id="chat">
    <channels>
        <channel ref="my-rtmp"/>
    </channels>
    <properties>
        <network>
            <session-timeout>20</session-timeout>
        </network>
        <server>
            <allow-subtopics>true</allow-subtopics>
        </server>
        <security>
            <security-constraint ref="privileged-users"/>
        </security>
    <properties>
</destination>
</service>
...
<security>
    <security-constraint id="privileged-users">
        <auth-method>Custom</auth-method>
        <roles>
            <role>privilegedusers</role> 
            <role>admins</role>
        </roles> 
    </security-constraint>
</security>
... 
<channels>
    <channel-definition id="my-rtmp" class="mx.messaging.channels.RTMPChannel">
        <endpoint uri="rtmp://{server.name}:1951" class="flex.messaging.endpoints.RTMPEndpoint"/>
    </channel-definition>
</channels>
...

对上面配置的说明:

1Message channels

当前版本的FluorineFx 只支持通过Realtime Message Protocol (RTMP) channel传输消息。

2Message Service adapter

FluorineFx中,默认的 Message Service adapter就是FluorineFx.Messaging.Services.Messaging.MessagingAdapter 类。所以配置文件如下设置:

    <adapter id="dotnet" class="FluorineFx.Messaging.Services.Messaging.MessagingAdapter" default="true"/>

如果编写MessagingAdapter类的子类,你就可以自己定义Adapter

3Network properties

Property element

Description

session-timeout

超过这个时间(单位:分钟),a subscriber is unsubscribed (如果没有或者值为 0 ,则表明不会自动unsubscribe)

4Server properties

Property element

Description

allow-subtopics

Destination是否支持subtopics (true/false)

subtopic-separator

不支持。所以总是"." ()

 


三、配置 Data Management Service

Data Management Service destination 是一个终端。这个终端可以接收数据,或者发送数据到客户机。它提供了将数据分布到多个Data Management Service destination和 在这些destination之间进行同步(synchronization)的能力。 在Flex中使用DataService 组件或ActionScript API可以连接到Data Management Service destination

例子:

<service id="data-service" class="flex.data.DataService" messageTypes="flex.data.messages.DataMessage">
<adapters>
    <adapter id="dotnet-dao" class="FluorineFx.DotNetAdapter" default="true"/>
</adapters>
<default-channels>
    <channel ref="my-rtmp"/>
</default-channels>
 
<destination id="crm.company">
    <adapter ref="dotnet-dao"/>
    <properties>
        <source>samples.crm.CompanyAssembler<source/>
        <scope>application<scope/>
        <metadata>
            <identity property="companyId"/>
        </metadata>
        <network>
            <session-timeout>20</session-timeout>
            <paging enabled="true" pageSize="10"/>
        </network>
    </properties>    
</destination>
</service>
... 
<channels>
    <channel-definition id="my-rtmp" class="mx.messaging.channels.RTMPChannel">
        <endpoint uri="rtmp://{server.name}:1951" class="flex.messaging.endpoints.RTMPEndpoint"/>
    </channel-definition>
</channels>
...
              

 

对上面配置的说明:

1Message channel的选择:

当前的FluorineFx 只支持使用Realtime Message Protocol (RTMP) channel 传输Data Management Services

2Data adapter的设置:

FluorineFx中的 Data adapter是由 FluorineFx.DotNetAdapter 类实现的:

    <adapter id="dotnet" class="FluorineFx.DotNetAdapter" default="true"/>

3Destination properties

Property element

描述

source

Fully qualified type name of the Data Assembler

scope

Valid values are request, application, and session. The default value is request.

cache-items

不支持, 总设置成true

auto-sync-enabled

4Network properties

Property element

描述

session-timeout

Idle time in minutes before a subscriber is unsubscribed (Missing element or the value 0 means do not unsubscribe automatically)

paging

Optional element specifying data paging settings. The enabled attribute (true/false) indicates whether data paging is enabled for the destination, the pageSize attribute indicates the number of records in a page.

5Metadata properties

Property element

描述

identity

Specifies data properties that provide object identity. The property attribute identifies the property name.

6Server properties

Property element

描述

allow-subtopics

Specifies whether subtopics are allowed for a destination (true/false)

subtopic-separator

Not supported. In FluorineFx the subtopic separator is always "." (period)
