mongodb的权限配置可以参考该文：【整理】CentOS 6.5 mongodb 3.2增加权限配置

C++代码中如果带权限连接，那么可以参考如下代码段：

try {
			mongo::DBClientConnection *conn = new mongo::DBClientConnection(auto_conn, 0, time_out);
			if (conn != NULL)
			{
				conn->connect("localhost");
				conn->auth(BSON("mechanism"<< "SCRAM-SHA-1" << "user" << "admin" << "pwd" << "admin" << "db" << "test_db"));
			}
		}
		catch (const mongo::ConnectException &e) {
			std::cout << "MongoDB无法访问! 问题:" << e.what() << std::endl;
			this->db_connect_status = false;
		}
		catch (const mongo::SocketException &e) {
			std::cout << "MongoDB无法访问! 问题:" << e.what() << std::endl;
			this->db_connect_status = false;
		}
		catch (const mongo::DBException &e) {
			std::cout << "MongoDB无法访问! 问题:" << e.what() << std::endl;
			this->db_connect_status = false;
		}

只要调用auth函数即可，函数原型为：
