错误日志信息支持Stack特性，该特性可以自动打印出当前调用日志组件方法的堆栈信息，该堆栈信息可以通过Notice*/Warning*/Error*/Critical*/Panic*/Fatal*等错误日志输出方法触发，也可以通过GetStack/PrintStack获取/打印。错误信息的stack信息对于调试来说相当有用。

示例1，通过错误方法触发

示例1，通过Error方法触发

Code Block
languagego
package main

import (
	"context"

	"github.com/gogf/gf/v2/os/glog"
)

func Test(ctx context.Context) {
	glog.Error(ctx, "This is error!")
}

func main() {
	ctx := context.TODO()
	Test(ctx)
}

打印出的结果如下：

示例2，通过Stack方法打印

Code Block
languagego
package main

import (
	"context"
	"fmt"

	"github.com/gogf/gf/v2/os/glog"
)

func main() {
	ctx := context.TODO()
	glog.PrintStack(ctx)
	glog.New().PrintStack(ctx)

	fmt.Println(glog.GetStack())
	fmt.Println(glog.New().GetStack())
}

执行后，输出结果为：

示例3，打印gerror.Error
glog日志模块支持对标准错误以及gerror错误的堆栈打印支持。
 Code Block
languagego
package main

import (
	"context"
	"errors"

	"github.com/gogf/gf/v2/errors/gerror"
	"github.com/gogf/gf/v2/os/glog"
)

func MakeError() error {
	return errors.New("connection closed with normal error")
}

func MakeGError() error {
	return gerror.New("connection closed with gerror")
}

func TestGError(ctx context.Context) {
	err1 := MakeError()
	err2 := MakeGError()
	glog.Error(ctx, err1)
	glog.
Error(
Errorf(ctx, "%+v", err2)
}

func main() {
	ctx := context.TODO()
	TestGError(ctx)
}


执行后，终端输出：
