logger
Logger module based on uber zap package,
which can be used to record operation logs in go applications
1) Support automatic log cutting and maximum retention time
2) Support log json formatting processing
3) Support log output to file and terminal at the same time
4) Support log printing level and log dyeing function
基于uber zap封装而成的logger模块，可用于go应用中记录操作日志
1）支持日志自动切割和最大保留时长
2）支持日志json格式化处理
3）支持日志同时输出到文件和终端
4）支持日志打印级别和日志染色功能
5）支持默认日志句柄调用，比如Info,Warn等方法调用

Variables ¶
var ( // XRequestID request_id XRequestID = CtxKey{"x-request-id"} // ReqClientIP client_ip ReqClientIP = CtxKey{"client_ip"} // RequestMethod request method RequestMethod = CtxKey{"request_method"} // RequestURI request uri RequestURI = CtxKey{"request_uri"} // LocalTime local_time LocalTime = CtxKey{"local_time"} // CurHostname current hostname CurHostname = CtxKey{"hostname"} // Fullstack full stack Fullstack = CtxKey{"full_stack"} )
var ( // DefaultLogDir default log dir. DefaultLogDir = "./logs" // DefaultLogFile default log file. DefaultLogFile = "go-app.log" )
Functions ¶
func Default ¶
func Default(opts ...Option)
Default 默认zap logger对象 WithWriteToFile 默认写入文件中，如需要在终端输入使用 logger.WithStdout(true) 开启
func NewLogSugar ¶
func NewLogSugar(opts ...Option) *zap.SugaredLogger
NewLogSugar zap log sugar语法糖 支持Debug,Info,Error,Panic,Warn,Fatal等方法 返回一个*zap.SugaredLogger
func RndUUID ¶
func RndUUID() string
RndUUID realizes unique uuid based on time ns and random number There is no duplication of uuid on a single machine If you want to generate non-duplicate uuid on a distributed architecture Just add some custom strings in front of rndStr Return format: eba1e8cd-0460-4910-49c6-44bdf3cf024d
Types ¶
type Logger ¶
type Logger interface {
// Debug debug级别日志
Debug(ctx context.Context, msg string, fields ...interface{})
// Info info级别日志
Info(ctx context.Context, msg string, fields ...interface{})
// Error 错误类型的日志
Error(ctx context.Context, msg string, fields ...interface{})
// Warn 警告类型的日志
Warn(ctx context.Context, msg string, fields ...interface{})
// DPanic 调试模式下的panic，程序不退出，继续运行
DPanic(ctx context.Context, msg string, fields ...interface{})
// Recover 用来捕获程序运行出现的panic信息，并记录到日志中
// 这个panic信息，将采用 DPanic 方法进行记录
Recover(ctx context.Context, msg string, fields ...interface{})
// Panic 抛出panic的时候，先记录日志，然后执行panic,退出当前goroutine
// 如果没有捕获，就会退出当前程序,建议程序做defer捕获处理
Panic(ctx context.Context, msg string, fields ...interface{})
// Fatal 抛出致命错误，然后退出程序
Fatal(ctx context.Context, msg string, fields ...interface{})
}
Logger interface.
type Option ¶
type Option func(z *zapLogWriter)
Option option for zapLogWriter
func WithCallerSkip ¶
* WithCallerSkip 设置callerSkip addCaller = true,并且 callerSkip > 0 会设置zap.AddCallerSkip zap源码包中logger.go#260 check func check must always be called directly by a method in the Logger interface (e.g., Check, Info, Fatal). const callerSkipOffset = 2 这里的callerSkipOffset默认是2 如果基于这个Logger包，再包装一次，这个 skip = 2,以此类推 否则 skip=1
func WithLogLevel ¶
WithLogLevel 日志级别，设置日志打印最低级别，如果不设置默认为info级别 zap.InfoLevel is the default logging priority.
