spdlog是一個(gè)C++的快速日志庫,用于在C++程序中進(jìn)行日志記錄。其用法主要包括以下幾個(gè)步驟:
#include <spdlog/spdlog.h>
auto logger = spdlog::stdout_logger_mt("console");
logger->info("This is an info message");
logger->error("This is an error message");
logger->set_level(spdlog::level::debug);
logger->set_pattern("[%Y-%m-%d %H:%M:%S.%e] [%l] %v");
auto custom_logger = spdlog::create<spdlog::sinks::basic_file_sink_mt>("custom_logger", "custom_log.txt");
auto file_logger = spdlog::basic_logger_mt("file_logger", "logs/simple_log.txt");
auto syslog_logger = spdlog::syslog_logger("syslog_logger", "my_program", LOG_PID);
auto windows_logger = spdlog::win_logger_mt("windows_logger", "Application");
通過以上步驟,可以在C++程序中方便地使用spdlog庫進(jìn)行日志記錄,提高程序的可維護(hù)性和調(diào)試效率。
