zap自定义日志级别
简介
zap是有uber开发的一款日志库。
zap提供了三个快速创建Logger方法:
- NewProduction: 以JSON格式记录Info级别及以上的标准错误日志
- NewDevelopment: 以JSON格式记录Debug级别及以上的标准错误日志
- NewExample: 提供一个测试实例,供使用者根据结果进行自定义Logger实例配置
- New: 实现自定义的Logger
支持的日志级别
zap支持6种日志级别:
const (
// DebugLevel logs are typically voluminous, and are usually disabled in
// production.
DebugLevel = zapcore.DebugLevel
// InfoLevel is the default logging priority.
InfoLevel = zapcore.InfoLevel
// WarnLevel logs are more important than Info, but don't need individual
// human review.
WarnLevel = zapcore.WarnLevel
// ErrorLevel logs are high-priority. If an application is running smoothly,
// it shouldn't generate any error-level logs.
ErrorLevel = zapcore.ErrorLevel
// DPanicLevel logs are particularly important errors. In development the
// logger panics after writing the message.
DPanicLevel = zapcore.DPanicLevel
// PanicLevel logs a message, then panics.
PanicLevel = zapcore.PanicLevel
// FatalLevel logs a message, then calls os.Exit(1).
FatalLevel = zapcore.FatalLevel
)
设置Logger日志级别
可以通过WithOption接口为Logger设置日志级别:
log.WithOptions(zap.IncreaseLevel(zapcore.DebugLevel))
