go - 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(如果遇到错误)，但问题是 log.Fatal() 正在退出程序并且log.Panic() 将调用再次退出程序的 panic()。

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记录库，例如 logrus或者像这样修改你的标准日志库:

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")

结果是:
