【TcaplusDB知识库】TDR表GOSDK示例代码-删除数据

使用工具TdrCodeGen将service_info.xml转为go代码

func deleteExample() {
    req, err := client.NewRequest(ZoneId, TableName, cmd.TcaplusApiDeleteReq)
    if err != nil {
        fmt.Printf("NewRequest TcaplusApiDeleteReq failed %v\n", err.Error())
        return
    }
    fmt.Printf("deleteExample NewRequest TcaplusApiDeleteReq finish\n")
    //设置结果标记位，删除成功后，返回tcaplus端的旧数据，默认为0
    if err := req.SetResultFlag(3); err != nil {
        fmt.Printf("SetResultFlag failed %v\n", err.Error())
        return
    }
    fmt.Printf("deleteExample SetResultFlag finish\n")

    //为request添加一条记录，（index只有在list表中支持，generic不校验）
    rec, err := req.AddRecord(0)
    if err != nil {
        fmt.Printf("AddRecord failed %v\n", err.Error())
        return
    }
    fmt.Printf("deleteExample AddRecord finish\n")
    //申请tdr结构体并赋值key，最好调用tdr pkg的NewXXX函数，会将成员初始化为tdr定义的tdr默认值，
    // 不要自己new，自己new，某些结构体未初始化，存在panic的风险
    data := service_info.NewService_Info()
    data.Gameid = "dev"
    data.Envdata = "oa"
    data.Name = "com"
    //将tdr的数据设置到请求的记录中
    if err := rec.SetData(data); err != nil {
        fmt.Printf("SetData failed %v\n", err.Error())
        return
    }
    if resp, err := client.Do(req, time.Duration(2*time.Second)); err != nil {
        fmt.Printf("recv err %s\n", err.Error())
        return
    } else {
        tcapluserr := resp.GetResult()
        if tcapluserr != 0 {
            fmt.Printf("response ret errCode: %d, errMsg: %s", tcapluserr, terror.GetErrMsg(tcapluserr))
            return
        }
        //获取同步请求Seq
        fmt.Printf("request Seq %d\n", req.GetSeq())
        //获取回应消息的序列号
        fmt.Printf("respond seq: %d \n", resp.GetSeq())
        //response中带有获取的旧记录
        fmt.Printf("deleteExample response success record count %d\n", resp.GetRecordCount())
        for i := 0; i < resp.GetRecordCount(); i++ {
            record, err := resp.FetchRecord()
            if err != nil {
                fmt.Printf("FetchRecord failed %s\n", err.Error())
                return
            }
            oldData := service_info.NewService_Info()
            if err := record.GetData(oldData); err != nil {
                fmt.Printf("record.GetData failed %s\n", err.Error())
                return
            }
            fmt.Printf("deleteExample response record data %+v, route: %s",
                oldData, string(oldData.Routeinfo[0:oldData.Routeinfo_Len]))
            fmt.Printf("deleteExample request  record data %+v, route: %s",
                data, string(data.Routeinfo[0:data.Routeinfo_Len]))
        }
    }
}
