使用github.com/pkg/errors打印詳細(xì)的堆棧信息步藕，輸出非常友好曙强。

設(shè)置堆棧打印詳細(xì)調(diào)用過(guò)程

zerolog.ErrorStackMarshaler = pkgerrors.MarshalStack

輸出詳細(xì)的堆棧信息

package main

import (
    "github.com/pkg/errors"
    "github.com/rs/zerolog"
    "github.com/rs/zerolog/log"
    "github.com/rs/zerolog/pkgerrors"
     "github.com/thinkeridea/go-extend/exbytes"
    "github.com/thinkeridea/go-extend/exstrings"
    "os"
    "strconv"
)

func C() error {
    _, err := os.Open("err")
    if err != nil {
        return errors.WithStack(err)
    }
    return nil
}

func B() error {
    return C()
}
func A() error {
    return B()
}
func init() {

    log.Logger = zerolog.New(os.Stderr).
        With().Timestamp().Stack().CallerWithSkipFrameCount(2).Logger()
    zerolog.CallerMarshalFunc = func(file string, line int) string {
        return WashPath(file) +":"+ strconv.Itoa(line)
    }
    // 使用官方提供的，輸出更友好
    zerolog.ErrorStackMarshaler = pkgerrors.MarshalStack
}

func main() {
    err := A()
    if err != nil {
        log.Error().Stack().Err(err).Msg("")
    }
}
// 路徑脫敏
func WashPath(s string) string {
    sb := exstrings.Bytes(s)
    path, _ := os.Getwd()
    pathByte := exbytes.Replace([]byte(path+"/"), []byte("\\"), []byte("/"), -1)
    root := os.Getenv("GOROOT")
    rootByte := exbytes.Replace([]byte(root+"/"), []byte("\\"), []byte("/"), -1)
    sb = exbytes.Replace(sb, pathByte, []byte(""), -1)
    sb = exbytes.Replace(sb, rootByte, []byte(""), -1)
    return exbytes.ToString(sb)
}
