Does not support parameter name like "a_b_c"

[lmyzzu]

if use parameter name like "a_b_c" , get the exception follow :
Can't parse message of type "***" because it is missing required fields: "a_b_c"

because object.serialize() not handle the fields: "a_b_c"
//common.proto
package org.commmon;
message BaseInfo
{
required string id = 1;
required int32 last_go_time = 8;
}
var fs = require('fs');
var Schema = require('protobuf').Schema;

var common = new Schema(fs.readFileSync("./protos/common.desc"));
var Info = fishingjoy3["org.commmon.BaseInfo"];
var pmsg = Info.serialize({
"id": 'id',
"last_go_time": 12452475
});
console.log(pmsg.length);
var jmsg=uInfo.parse(pmsg);
console.log(jmsg);
