C++ C++；cassandra客户端选择int值

我正在尝试选择一个整数值，但无法选择 这是我的代码：

cassandra_socket = boost::shared_ptr<TSocket>(new TSocket(host, port));
cassandra_transport = boost::shared_ptr<TFramedTransport>(new TFramedTransport(cassandra_socket));
protocol = boost::shared_ptr<TBinaryProtocol>(new TBinaryProtocol(cassandra_transport));
cassandra_client = new CassandraClient(protocol);
try {
    cassandra_transport->open();
    cassandra_client->set_keyspace("MPS");
    ColumnOrSuperColumn csc;
    ColumnPath cpath;
    cpath.column_family.assign("SubmitResposes_count");
    /* This is required - thrift 'feature' */
    cpath.__isset.column = true;
    cpath.column = "Counter";
    cassandra_client->get(csc, "1", cpath,org::apache::cassandra::ConsistencyLevel::ONE);
    cout << "Value read is '" << csc.column.value << "'..." << endl;
}
catch (NotFoundException &nf) {
    FORCE_TRACE(0, "NOT FOUND EXCEPTION ERROR: %s", nf.what());
} catch (InvalidRequestException &re) {
    FORCE_TRACE(0, "INVALID REQUEST ERROR: %s", re.why);
} catch (TException &tx) {
    FORCE_TRACE(0, "TEEXCEPTION ERROR: %s", tx.what());
}

您的密钥是int：

ID int primary key,

但您正在使用字符串键进行查询：

cassandra_client->get(csc, "1", cpath,org::apache::cassandra::ConsistencyLevel::ONE);
                           ^^^

Cassandra正在尝试将字符串验证为int，这导致了此异常。

函数“get”仅接受字符串如何使用整数键进行查询？您似乎在使用旧的thrift规范。该函数使用二进制键。您是否考虑过使用高级客户机而不是节俭？除非你有特定的理由，否则不建议直接使用节俭。

cassandra_client->get(csc, "1", cpath,org::apache::cassandra::ConsistencyLevel::ONE);
                           ^^^
