【TcaplusDB知识库】PB表C++示例代码-插入List表数据

前提

成功创建:集群,表格组,tb_online表
tb_online表描述文件​​table_test.proto腾讯云电脑​​如下:(​​tcaplusservice.optionv1.p腾讯云服务器12元一年roto​​为依赖表)

syntax = "proto3";

package myTcaplusTable;
//import tcaplusdb extensions
import "tcaplusservice.optionv1.proto";

message tb_online {
//define primary key
option(tcaplusservice.tcaplus_primary_key) = "openid,tconndid,timekey";
//primary key fields
int32 openid = 1; //QQ Uin
int32 tconndid = 2;
string timekey = 3;

//non-primary key fields
string gamesvrid = 4;
int32 logintime = 5 ;
repeated int64 lockid = 6;
pay_info pay = 7;

message pay_info {
uint64 total_money = 1;
uint64 pay_times = 2;
}

}

定义配置参数

// 目标业务的tcapdir地址
static const char DIR_URL_ARRAY[][TCAPLUS_MAX_STRING_LENGTH] =
{
"tcp://10.191.***.99:9999"
};
// 目标业务的tcapdir 地址个数
static const int32_t DIR_URL_COUNT = 1;

// 目标业务的集群ID
static const int32_t APP_ID = 3;
// 目标业务的表格组ID
static const int32_t ZONE_ID = 1;
// 目标业务的业务密码
static const char * SIGNATURE = "*******";
// 目标业务的表名 tb_online
static const char * TABLE_NAME = "tb_online";

初始化TcaplusPB客户端

//Tcaplus PB API客户端
TcaplusAsyncPbApi g_stAsyncApi;
int32_t InitAsyncPbApi()
{
//PB API配置
ClientOptions cfg;
cfg.app_id = APP_ID;
cfg.zones.push_back(ZONE_ID);
strcpy(cfg.signature, SIGNATURE);
for (int32_t i = 0; i < DIR_URL_COUNT; i++)
{
cfg.dirs.push_back(DIR_URL_ARRAY[i]);
}
//访问的PB表
cfg.tables.push_back(TABLE_NAME);
//日志配置
strncpy(cfg.log_cfg, "tlogconf.xml", sizeof(cfg.log_cfg));
//初始化连接超时时间5s
cfg.timeout = 5000;

//初始化连接
int32_t iRet = g_stAsyncApi.Init(cfg);
if (0 != iRet)
{
cout << "ERROR: g_stAsyncApi.Init failed, log cfg: " << cfg.log_cfg << ", iRet: " << iRet << "." << endl;
return iRet;
}
return iRet;
}

定义异步回调数据库设计

class CommonCallback : public TcaplusPbCallback
{
public:
CommonCallback()
{
cout << "Init CommonCallback." << endl;
}

<sub>CommonCallback()
{
cout << "Fini </sub>CommonCallback." << endl;
}

int OnRecv(const NS_TCAPLUS_PROTOBUF_API::ListAddAfterRequest &req, NS_TCAPLUS_PROTOBUF_API::ListAddAfterResponse *res)
{
cout << "OnRecv[" << res->m_mapMsg.size() << " index: "<< res->m_nElemIndex << endl;
g_dwTotalRevNum++;
std::map<int, ::google::protobuf::Message*>::iterator itMap = res->m_mapMsg.begin();
for (; itMap != res->m_mapMsg.end(); itMap++)
{
tb_online_list* t = dynamic_cast<tb_online_list *>(itMap->second);
if (NULL == t)
{
cout << "ERROR: msgs[" << itMap->first << "] not tb_online_list type." << endl;
return -1;
}

cout << "---------- receive a response----------:" << itMap->first << endl;
cout << "openid=" << t->openid() << endl;
cout << "tconndid=" << t->tconndid() << endl;
cout << "timekey=" << t->timekey() << endl;
cout << "gamesvrid=" << t->gamesvrid() << endl;
tb_online_list_pay_info pay = t->pay();
cout << "pay total_money=" << pay.total_money() << "; pay_times=" << pay.pay_times() << endl;

std::string version;
int iRet = g_stAsyncApi.GetMessageOption(*t, NS_TCAPLUS_PROTOBUF_API::MESSAGE_OPTION_DATA_VERSION, &version);
cout << "after GetMessageOption iRet= [" << iRet << "] version:" << version.c_str() << " msg:" << t << endl;
}

return 0;
}

int OnError(const std::vector< ::google::protobuf::Message *> &msgs, int errorcode)
{
cout << "OnError[" << msgs.size() << endl;
g_dwTotalRevNum++;
for (size_t idx = 0; idx < msgs.size(); idx++)
{
tb_online_list* t = dynamic_cast<tb_online_list *>(msgs[idx]);
if (NULL == t)
{
cout << "ERROR: msgs[" << idx << "] not tb_online_list type." << endl;
return -1;
}

if (TcapErrCode::TXHDB_ERR_RECORD_NOT_EXIST == errorcode)
{
cout << "ERROR: openid= " << t->openid() << ", tconndid= " << t->tconndid() << ", timekey= " << t->timekey() << ", record not exists" << endl;
}
cout << "ERROR: openid = [" << t->openid() << "], tconndid = [" << t->tconndid() << "], timekey =[" << t->timekey() << "] failed:%d" << errorcode << endl;
}

return 0;
}

int OnTimeout(const std::vector< ::google::protobuf::Message *> &msgs)
{
cout << "OnTimeout[" << msgs.size() << endl;
for (size_t idx = 0; idx < msgs.size(); idx++)
{
tb_online_list* t = dynamic_cast<tb_online_list *>(msgs[idx]);
if (NULL == t)
{
cout << "TIMEOUT: msgs[" << idx << "] not tb_online_list type!" << endl;
return -1;
}

cout << "TIMEOUT: openid = [" << t->openid() << "], tconndid = [" << t->tconndid() << "], timekey =[" << t->timekey() << "] timeout" << endl;
}

return 0;
}

int OnFinish(const NS_TCAPLUS_PROTOBUF_API::MsgParam &m)
{
cout << "OnFinish: " << param.m_nOperation << " req: " << param.m_reqListAddAfter << endl;
return 0;
}

};

发送AddAfter数据库是什么请求

void SendAddAfterRequest(struct schedule * S, void* arg)
{
static tb_online_list t;
t.set_openid(2);
t.set_tconndid(2);
t.set_timekey("test_tcaplus_2");
t.set_gamesvrid("MyValueStr_2");
t.set_logintime(333);
t.set_add(333);

tb_online_list_pay_info* pay = new tb_online_list_pay_info();
pay->set_total_money(1024);
pay->set_pay_times(1);
t.set_allocated_pay(pay);

cout << "INIT: openid= " << t.openid() << ", tconndid= " << t.tconndid() << ", timekey= " << t.timekey() << endl;

std::string version = "-1";
g_stAsyncApi.SetMessageOption(t, NS_TCAPLUS_PROTOBUF_API::MESSAGE_OPTION_DATA_VERSION, version);

static CommonCallback cb;
static NS_TCAPLUS_PROTOBUF_API::ListAddAfterRequest req;
req.m_pMsg = &t;
req.m_nShift = 0;
req.m_nElemIndex = TCAPLUS_PB_API_LIST_LAST_INDEX;
int32_t iRet = g_stAsyncApi.ListAddAfter(req, &cb);
if (iRet != TcapErrCode::GEN_ERR_SUC)
{
cout << "ERROR: openid= " << t.openid() << ", tconndid= " << t.tconndid() << ", timekey= " << t.timekey() << ", Set Error iRet = " << iRet << endl;
}
}

示例

main.cpp

int main(void) {

//初始化API客户端
int ret = InitAsyncPbApi();
if ( ret != 0)
{
printf("InitAsyncPbApi failed\n");
return -1;
}

//发送请求
ret = SendAddAfterRequest();
if (0 != ret)
{
printf("SendAddRequest failed\n");
return -1;
}

//接收响应
do
{
// 更新,接收回包
g_stAsyncApi.UpdateNetwork();
usleep(1000 * 10);
} while (g_dwTotalRevNum != 1);
return 0;
}
