此为信令扩展部分 关键部分如下
1定义群组CMD
pb/IM.BaseDefine.proto
CID_GROUP_CHANGE_NAME_REQUEST = 0x040c,//群组名修改请求
CID_GROUP_CHANGE_NAME_RESPONSE = 0x040d,//响应
CID_GROUP_CHANGE_NAME_NOTIFY = 0x040e,//通知
2定义群组协议修改群名 req? rsp notify
pb/IM.Group.proto
message IMGroupChangeGroupNameReq{
//cmd id: 0x040c
required uint32 user_id = 1;
required uint32 group_id = 2;
required string group_name = 3;
optional bytes attach_data = 20;
}
message IMGroupChangeGroupNameRsp{
//cmd id: 0x040d
required uint32 user_id = 1;
required uint32 group_id = 2;
required uint32 result_code = 3;
optional bytes attach_data = 20;
repeated uint32 cur_user_id_list = 4; //notify stick
}
message IMGroupChangeGroupNameNotifyRsp{
//cmd id: 0x040d
required uint32 user_id = 1;
required uint32 group_id = 2;
required string group_name = 3;
repeated uint32 cur_user_id_list = 4; //现有的成员id
optional bytes attach_data = 20;
}3生成协议
cd pb
./create.sh? ? ??
./sync.sh
4注册Db HandlerMap接口
dg/business/GroupAction.h
#include "ImPduBase.h"
namespace DB_PROXY {
void createGroup(CImPdu* pPdu, uint32_t conn_uuid);
...
void changeGroupName(CImPdu* pPdu, uint32_t conn_uuid);
}; // group
m_handler_map.insert(make_pair(uint32_t(CID_GROUP_NORMAL_LIST_REQUEST),
...
....
m_handler_map.insert(make_pair(uint32_t(CID_GROUP_CHANGE_NAME_REQUEST), DB_PROXY::changeGroupName));GroupAction.cpp? 添加实现
/**
* modify group name
*
* @param pPdu 收到的packet包指针
* @param conn_uuid 该包过来的socket 描述符
*/
void changeGroupName(CImPdu *pPdu, uint32_t conn_uuid)
{
IM::Group::IMGroupChangeGroupNameReq msg;
IM::Group::IMGroupChangeGroupNameRsp msgResp;
if (msg.ParseFromArray(pPdu->GetBodyData(), pPdu->GetBodyLength()))
{
uint32_t nUserId = msg.user_id();
uint32_t nGroupId = msg.group_id();
string strGroupName = msg.group_name();
if (CGroupModel::getInstance()->isValidateGroupId(nGroupId))
{
CImPdu *pPduRes = new CImPdu;
log("change group name uid = %d group_id = %d name = %s", nUserId, nGroupId, strGroupName.c_str());
bool bRet = CGroupModel::getInstance()->changeGroupName(nUserId,nGroupId, strGroupName);
msgResp.set_user_id(nUserId);
msgResp.set_group_id(nGroupId);
msgResp.set_result_code(bRet ? 0 : 1);
//query all users in group and notify
list<uint32_t> lsCurUserId;
CGroupModel::getInstance()->getGroupUser(nGroupId, lsCurUserId);
for (auto it = lsCurUserId.begin(); it != lsCurUserId.end(); ++it)
{
msgResp.add_cur_user_id_list(*it);
}
//response
msgResp.set_attach_data(msg.attach_data());
pPduRes->SetPBMsg(&msgResp);
pPduRes->SetSeqNum(pPdu->GetSeqNum());
pPduRes->SetServiceId(IM::BaseDefine::SID_GROUP);
pPduRes->SetCommandId(IM::BaseDefine::CID_GROUP_CHANGE_NAME_RESPONSE);
CProxyConn::AddResponsePdu(conn_uuid, pPduRes);
}
else
{
log("invalid groupModifyType or groupId. userId=%u, groupId=%u", nUserId, nGroupId);
}
}
else
{
log("parse pb failed");
}
}
}5 添加数据库修改群名接口 同时更新 update字段?
GroupModel.cpp
bool CGroupModel::changeGroupName(uint32_t nUserId, uint32_t nGroupId, const string &strGroupName)
{
bool bRet = false;
if (hasModifyPermission(nUserId, nGroupId))
{
bRet = updateGroupName(nGroupId, strGroupName);
//if modify group member success, need to inc the group version and clear the user count;
if (bRet)
{
incGroupVersion(nGroupId);
}
}
else
{
log("user:%u has no permission to modify group:%u", nUserId, nGroupId);
}
return bRet;
}
bool CGroupModel::updateGroupName(uint32_t nGroupId, const string &strGroupName)
{
bool bRet = false;
CDBManager *pDBManager = CDBManager::getInstance();
CDBConn *pDBConn = pDBManager->GetDBConn("teamtalk_master");
if (pDBConn)
{
uint32_t nNow = (uint32_t)time(NULL);
// string strSql = "update IMGroup set name= " + strGroupName + " where id=" + int2string(nGroupId);
// string strSql = "update IMGroup set `name`='" + strGroupName + "' ,' updated'=" + int2string(nNow) + " where id=" + int2string(nGroupId);
string strSql = "update IMGroup set `name`='" + strGroupName + "', `updated`=" + int2string(nNow) + " where id="+int2string(nGroupId);
log("updateGroupName,%s ", strSql.c_str());
bRet = pDBConn->ExecuteUpdate(strSql.c_str());
pDBManager->RelDBConn(pDBConn);
}
else
{
log("no db connection for teamtalk_master");
}
return bRet;
}
6添加MSG_server? ?req HandleGroupNameResponse? HandleGroupNameNotify? 接口
msg_server处理请求
