Go Uber Zap logger未在日志语句中打印调用方信息

我正试图将相同的消息放在控制台和日志文件中，同时使用自定义编码器进行配置。在此过程中，我希望显示呼叫者信息，但即使使用了文档中建议的

caller

键，也不会显示呼叫者信息。下面是相同的示例代码

package main

import (
    "os"
    "time"

    "go.uber.org/zap"
    "go.uber.org/zap/zapcore"
    "gopkg.in/natefinch/lumberjack.v2"
)

var logLevelSeverity = map[zapcore.Level]string{
    zapcore.DebugLevel:  "DEBUG",
    zapcore.InfoLevel:   "INFO",
    zapcore.WarnLevel:   "WARNING",
    zapcore.ErrorLevel:  "ERROR",
    zapcore.DPanicLevel: "CRITICAL",
    zapcore.PanicLevel:  "ALERT",
    zapcore.FatalLevel:  "EMERGENCY",
}

func SyslogTimeEncoder(t time.Time, enc zapcore.PrimitiveArrayEncoder) {
    enc.AppendString(t.Format("Jan 01, 2006  15:04:05"))
}

func CustomEncodeLevel(level zapcore.Level, enc zapcore.PrimitiveArrayEncoder) {
    enc.AppendString(logLevelSeverity[level])
}

func CustomLevelFileEncoder(level zapcore.Level, enc zapcore.PrimitiveArrayEncoder) {
    enc.AppendString("[" + logLevelSeverity[level] + "]")
}

func main() {

    w := zapcore.AddSync(&lumberjack.Logger{
        Filename:   "temp1.log",
        MaxSize:    1024,
        MaxBackups: 20,
        MaxAge:     28,
        Compress:   true,
    })

    //Define config for the console output
    cfgConsole := zapcore.EncoderConfig{
        MessageKey:   "message",
        LevelKey:     "severity",
        EncodeLevel:  CustomEncodeLevel,
        TimeKey:      "time",
        EncodeTime:   SyslogTimeEncoder,
        CallerKey:    "caller",
        EncodeCaller: zapcore.FullCallerEncoder,
    }
    cfgFile := zapcore.EncoderConfig{
        MessageKey:   "message",
        LevelKey:     "severity",
        EncodeLevel:  CustomLevelFileEncoder,
        TimeKey:      "time",
        EncodeTime:   SyslogTimeEncoder,
        CallerKey:    "caller",
        EncodeCaller: zapcore.FullCallerEncoder,
    }

    consoleDebugging := zapcore.Lock(os.Stdout)
    //consoleError := zapcore.Lock(os.Stderr)
    core := zapcore.NewTee(
        zapcore.NewCore(zapcore.NewConsoleEncoder(cfgFile), w, zap.DebugLevel),
        zapcore.NewCore(zapcore.NewJSONEncoder(cfgConsole), consoleDebugging, zap.DebugLevel),
        //zapcore.NewCore(zapcore.NewJSONEncoder(zap.NewProductionEncoderConfig()), consoleError, zap.ErrorLevel),
    )
    //core := zapcore.NewCore(zapcore.NewConsoleEncoder(encConsole), w, zap.DebugLevel)
    wlogger := zap.New(core)
    wlogger.Debug("Sample debug for log file and console")
    wlogger.Warn("An warning message example")
    wlogger.Info("An info level message")
    coreFile := zapcore.NewCore(zapcore.NewConsoleEncoder(cfgFile), w, zap.DebugLevel)
    flogger := zap.New(coreFile)
    flogger.Debug("An exclusive message for file")
    //output
    //{"severity":"DEBUG","time":"Nov 11, 2018  20:24:11","message":"Sample debug for log file and console"}
    //{"severity":"WARNING","time":"Nov 11, 2018  20:24:11","message":"An warning message example"}
    //{"severity":"INFO","time":"Nov 11, 2018  20:24:11","message":"An info level message"}
}

有没有想过为什么不显示呼叫者信息

根据文件 您可以在创建记录器时执行以下操作：

wlogger := zap.New(core, zap.AddCaller())

您还可以定义调用方编码的实现：

func MyCaller(caller zapcore.EntryCaller, enc zapcore.PrimitiveArrayEncoder) {
    enc.AppendString(filepath.Base(caller.FullPath()))
}

并将其传递给cfgConsole和cfgFile

可以帮助您跳过调用方的调用堆栈深度

//之前
New（core，zap.AddCaller（））
//输出：{“level”：“panic”，“time”：“2020-06-09T16:08:25.677+0800”，“line”：“log/log.go:118”，“msg”：“before”）}
//添加调用者跳过
New（core，zap.AddCaller（），zap.AddCallerSkip（1））
//输出：{“level”：“panic”，“time”：“2020-06-09T16:47:39.559+0800”，“line”：“client/client.go:29”，“msg”：“在”}

它可以工作，但是如何将文件名改为

go play/log.go:75

到

log.go:75

您可以定义CallerCoder的实现

func MyCaller（caller zapcore.EntryCaller，enc zapcore.PrimitiveArrayEncoder）{enc AppendString（filepath.Base（caller.FullPath（））}
