pbjs将proto定义的文件转换成了js用require汇入后，怎么获取协议定义？
比如：
// greeter.proto
syntax = “proto3”;
message HelloRequest {
uint32 cmd_id = 1; //协议号
uint32 to = 2; //目标服务器
uint64 serial_code = 4; //消息请求编号，默认为0
}
message HelloReply {
uint32 cmd_id = 1; // 协议号
uint32 error_code = 2; // 错误码
}
转换后的为：
`
// Common aliases
var $protobuf = protobuf;
var $Reader = $protobuf.Reader, $Writer = $protobuf.Writer, $util = $protobuf.util;
