关于golang:golang-zap日志库使用

1.装置zap

go get go.uber.org/zapgo get github.com/natefinch/lumberjack  //日志文件宰割包

2.根本应用

func main() {    logger, _ := zap.NewProduction() //生产环境实例    defer logger.Sync()   //将缓存中的日志同步到文件中    url := "http://xiayuedu.com"    logger.Info("info",                 //info级别的日志        zap.String("url",url),        zap.Bool("bool",true),    )    logger.Info("info",        zap.Namespace("namespace-1"),   //定义多级日志        zap.String("url",url),          //应用对应的类型        zap.Bool("bool",true),    )    logger.Info("info",        zap.Namespace("namespace-2"),        zap.String("url",url),        zap.Bool("bool",true),        )    logger.Error("password is error",       //error级别        zap.String("username","zhangsan"),         zap.String("password","123456"),      )    logger.Debug("record user info",      //debug级别        zap.String("username","zhangsan"),        zap.String("password","123456"),    )    sugar := logger.Sugar()             //应用非zap.xxxx类型进行输入，性能较低，非核心代码处能够应用    sugar.Info("sugar info",true,"123q342534",time.Second)    sugar.Error("sugar info",true,"123q342534",time.Second)    sugar.Debug("sugar info",true,"123q342534",time.Second)    sugar.Warn("sugar info",true,"123q342534",time.Second)}

输入后果

{"level":"info","ts":1627910714.8048513,"caller":"golangdemo/main.go:357","msg":"info","url":"http://xiayuedu.com","bool":true}{"level":"info","ts":1627910714.805827,"caller":"golangdemo/main.go:361","msg":"info","namespace-1":{"url":"http://xiayuedu.com","bool":true}}{"level":"info","ts":1627910714.806803,"caller":"golangdemo/main.go:366","msg":"info","namespace-2":{"url":"http://xiayuedu.com","bool":true}}{"level":"error","ts":1627910714.806803,"caller":"golangdemo/main.go:371","msg":"password is error","username":"zhangsan","password":"123456","stacktrace":"main.main\n\tC:/Users/admin/xiayuedu/golangdemo/main.go:371\nruntime.main\n\tC:/Program Files/Go/src/runtime/proc.go:203"}{"level":"info","ts":1627910714.8077793,"caller":"golangdemo/main.go:381","msg":"sugar infotrue123q3425341s"}{"level":"error","ts":1627910714.8077793,"caller":"golangdemo/main.go:382","msg":"sugar infotrue123q3425341s","stacktrace":"main.main\n\tC:/Users/admin/xiayuedu/golangdemo/main.go:382\nruntime.main\n\tC:/Program Files/Go/src/runtime/proc.go:203"}{"level":"warn","ts":1627910714.8087556,"caller":"golangdemo/main.go:384","msg":"sugar infotrue123q3425341s"}

3.定制化应用
