我不是GoLang的专家,但我需要对项目进行故障排除。现在我试图打印相同变量的值,但我收到的是地址而不是值:
attrs := core.Attributes{}
err = rtrV1.SetAttributesStruct(&attrs, sessAttrs, session.NasIP, ipv4Session, ipv6Session)
if err1, ok := err.(core.SessionNotFoundError); ok {
apiH.Logger.Info(err1.Error())
c.JSON(404, gin.H{"message": err.Error()})
return
} else if err != nil {
apiH.Logger.Error(err.Error())
c.JSON(500, gin.H{"message": "internal error"})
return
}
err = core.MakeNASProxyRequest(apiH.HttpClient, nasproxyHost, nasproxyPort, authToken, attrs)
debugAttrs := fmt.Sprintf("%+p", attrs)
debugAttrs2 := fmt.Sprintf("%+v", attrs)
apiH.Logger.Info("attrs:"+" "+debugAttrs, log.Field("type", "serve-request"))
apiH.Logger.Info("attr2:"+" "+debugAttrs2, log.Field("type", "serve-request"))
我需要打印attrs
,但我收到了以下输出:
"msg":"attrs: %!p(core.Attributes={+0xc000420460 <nil> <nil> +0xc000238c60 <nil> <nil> <nil> <nil> +0xc000238c98 <nil> <nil> <nil> <nil>})"
"msg":"attr2: {NASIPAddress:0xc000420460 NASIdentifier:<nil> NASIPv6Address:<nil> Username:0xc000238c60 NASPort:<nil> FramedIPAddress:<nil> CalledStationID:<nil> CallingStationID:<nil> AcctSessionID:0xc000238c98 AcctMultiSessionID:<nil> NASPortID:<nil> FramedInterfaceID:<nil> FramedIPv6Prefix:<nil>}"
如何打印值?感谢的帮助
您可以使用fmt
包或JSON封送处理来打印结构值。。。例如
import "fmt"
type Person struct {
FirstName string
}
func main() {
p := &Person{"mr1"}
fmt.Printf("%+v", p)
}
或
import (
"encoding/json"
"fmt"
)
type Person struct {
FirstName string
}
func main() {
p := &Person{"mr1"}
s, _ := json.Marshal(p)
fmt.Printf("%sn", s)
}
您可以使用deep-pretty打印机。导入:github.com/davecgh/go-spew/spew
示例:
spew.Dump(attrs)
