如何在不退出golang程序的情况下记录错误？

Question

我每 5 分钟运行一次任务，我想在不退出程序的情况下记录错误（如果它遇到错误），但问题是log.Fatal()退出程序log.Panic()并将调用panic()它再次退出程序。如何在不退出程序的情况下记录错误？

Answer 1

您可以使用不同的日志库，如logrus或修改标准日志库，如下所示：

日志包：

// Info writes logs in the color blue with "INFO: " as prefix

var Info = log.New(os.Stdout, "\u001b[34mINFO: \u001B[0m", log.LstdFlags|log.Lshortfile)

// Warning writes logs in the color yellow with "WARNING: " as prefix

var Warning = log.New(os.Stdout, "\u001b[33mWARNING: \u001B[0m", log.LstdFlags|log.Lshortfile)

// Error writes logs in the color red with "ERROR: " as prefix

var Error = log.New(os.Stdout, "\u001b[31mERROR: \u001b[0m", log.LstdFlags|log.Lshortfile)

// Debug writes logs in the color cyan with "DEBUG: " as prefix

var Debug = log.New(os.Stdout, "\u001b[36mDEBUG: \u001B[0m", log.LstdFlags|log.Lshortfile)

用法：

Error.Println("this is an error")

结果将是：
