README

Zerolog 使用示例

仅供参考, 若对日志性能要求不高, 可以选择: gxlog

特征

1. 开发环境时, 日志高亮输出到控制台
2. 生产环境时, 日志输出到文件(可选关闭高亮, 保存最近 10 个 30 天内的日志), 并发送 JSON 日志到 ES
3. 适应配置热加载时更新日志输出模式和日志级别
4. 路径脱敏, 不同级别日志输出到不同文件或设备, Hook, Stacktrace等示例

效果

1. basic/basic.go

16:21:46 INF basic.go:109 > test INFO
16:21:46 WRN basic.go:110 > test WARN
16:21:46 ERR basic.go:113 > test ERROR with Field error="fake error" k1=123
16:21:46 ERR basic.go:118 > test ERROR json.key error="my error msg"

2. for-project/main.go
