FluorineFX远程过程调用的机制

远程过程调用（ RPC ）是一种技术，让电脑程序造成子程序或程序来执行，在另一个地址空间——常见的情况是在另一台计算机上，而程序员不需明白这些远程交互的编码细节。

一个RPC的调用过程，是由客户端发送请求信息传递到已知的远程服务器，以执行指定程序使用提供的参数。一个回求返回给客户端当应用继续沿保持进 程。

对象参数传递机制，在一个远程调用的呼叫请求被称做对象序列。

RPC的内部结构(RPC internals)

Flash Remoting能让Flash客户端运行在浏览器或者一个用户桌面来存取和引用服务端运行的J2EE, Cold Fusion, 或者.NET 应用服务的方法。

Flash Player从二进制信息格式（AMF）处理串联和deserializing ActionScript对象。AMF序列对象是Flash客户端和应用服务之间HTTP请求和响应发送的有效载荷。

在ASP.NET服务端Flash Remoting由HttpModule组成，在FluorineFx的例子中Fluorine网关（FluorineGateway）类和所有支持类 库。网关序列化AMF信息、定位和引用方法，然后序列化.NET对象并返回值。

原文：

Remote procedure call (RPC) is a technology that allows a computer program to cause a subroutine or procedure to execute in another address space - commonly on another computer, without the programmer explicitly coding the details for this remote interaction.

A RPC is initiated by the client sending a request message to a known remote server in order to execute a specified procedure using supplied parameters. A response is returned to the client where the application continues along with its process.

The object parameter-passing mechanism in a remote call request is called object serialization.

Flash Remoting enables Flash clients running in a browser or on a user's desktop to access and invoke methods on server-side components running in a J2EE, Cold Fusion, or .NET application server.

The Flash player handles serializing and deserializing ActionScript objects to and from Action Message Format(AMF). AMF serialized objects are the payload of HTTP requests and responses sent between the Flash MX client and the application server.

On the ASP.NET server-side Flash Remoting consists of an HttpModule, in FluorineFx's case the FluorineGateway class and all the supporting classes. The gateway deserializes AMF messages, locates and invokes methods on .NET objects then serializes the method return value.
