我有一个用 Java 运行的简单 Google Protocol Buffers 服务器，我的朋友需要从他的 actionscript 3 应用程序中访问它。我们发现从 *.proto 生成类很容易：

protoc --plugin=protoc-gen-as3=protoc-gen-as3.bat --as3_oututput my.proto

但是对于实际的配置（设置服务器地址和端口）、获取通信通道以及实际调用*.proto中定义的服务，我们都傻眼了。

在 Java 中，借助 的帮助非常容易DuplexTcpClientBootstrap，但是 actionscript 呢？我尝试使用谷歌搜索，但我能找到的所有内容都只与从中生成类有关*.proto，没有调用实际方法/函数的示例。

TIA，我将不胜感激任何链接或示例！

使用“pafau k”，我们有 Java 服务器——它使用 protobuf——但它是写入套接字的。我认为我们有一些误解，因为 flex 可能适用于“http”协议——我说的对吗？

var callService:CallcenterService = new CallcenterService();
var simpleWebRPC:SimpleWebRPC = new SimpleWebRPC("0.0.0.0:1234/");
callService.sendFunction = xmlsock.send;
callService.getDefaults(new EmptyMessage(), function(result:*):void {
  var response:Defaults = result as Defaults;
  if (response){
    trace("RPC call succeeded:", response);
  }
  else{
     trace("RPC call failed:", ErrorEvent(result).text);
  }
});

callService 是从 proto 生成的

message EmptyMessage {}
message Defaults {
    required string xmlContents = 1;
}
service CallcenterService {
    rpc getDefaults (EmptyMessage) returns (Defaults);
}

这是来自 java 服务器的错误：
