glog对日志分析工具非常友好，支持输出JSON
...
格式的日志内容，以便于后期对日志内容进行解析分析。
使用map/struct参数
想要支持JSON数据格式的日志输出非常简单，给打印方法提供map/struct类型参数即可。
使用示例：
| Code Block | ||
|---|---|---|
| ||
package main
import (
" |
...
context" "github.com/gogf/gf/ |
...
v2/frame/ |
...
g" ) func main() { |
...
ctx := context.TODO() g.Log().Debug(ctx, g.Map{"uid" |
...
: 100, "name" |
...
: "john"})
type User struct {
Uid int `json:"uid"`
Name string `json:"name"`
}
|
...
g.Log().Debug(ctx, User{100, "john"}) } |
...
执行后，终端输出结果：
| Code Block | ||
|---|---|---|
| ||
2019-06-02 15:28:52.653 [DEBU] {"name":"john","uid":100} 2019-06-02 15:28:52.653 [DEBU] {"uid":100,"name":"john"} |
结合gjson.MustEncode
此外，也可以结合gjson.MustEncode来实现Json内容输出，例如：
| Code Block | ||
|---|---|---|
| ||
package main import ( "context" "github.com/gogf/gf/v2/encoding/gjson" "github.com/gogf/gf/v2/frame/g" ) func main() { ctx := context.TODO() type User struct { Uid int `json:"uid"` Name string `json:"name"` } g.Log().Debugf(ctx, `user json: %s`, gjson.MustEncode(User{100, "john"})) } |
执行后，终端输出结果：
| Code Block | ||
|---|---|---|
| ||
2022-04-25 18:09:45.029 [DEBU] user json: {"uid":100,"name":"john"} |
