Question

我有一个用Java运行的简单的Google Protocol Buffers服务器，我的朋友需要从他的actionscript 3应用程序访问它。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

但我们对实际配置（设置服务器地址和端口），获取通信通道以及实际调用* .proto中定义的服务非常傻。

在Java中，在DuplexTcpClientBootstrap的帮助下很容易，但是动作脚本是什么？我尝试使用谷歌搜索，但我能找到的所有内容只与从*.proto生成类有关，没有调用实际方法/函数的示例。

TIA，我会感激任何链接或示例！

使用“pafau k”我们有Java服务器 - 它使用protobuf - 但它写入套接字。我认为我们有一些误解，因为flex可能在“http”协议上工作 - 我是对的吗？

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：
