A simple but powerful golang log Toolkit
- Support at the same time to console, file, URL
- console output fonts can be colored with
- File output supports three types of segmentation based on the size of the file, the number of file lines, and the date.
- file output support is saved to different files at the log level.
- Two ways of writing to support asynchronous and synchronous
- Support json format output
- The code is designed to be extensible, and you can design your own adapter as needed
go get github.com/phachon/go-logger go get ./... go 1.8
- console // write console
- file // write file
- api // http request url
- ...
- sync
import ( "github.com/phachon/go-logger" ) func main() { logger := go_logger.NewLogger() logger.Info("this is a info log!") logger.Errorf("this is a error %s log!", "format") } - async

| Field | Alias | Type | Comment | Example |
|---|---|---|---|---|
| Timestamp | timestamp | int64 | unix timestamp | 1521791201 |
| TimestampFormat | timestamp_format | string | timestamp format | 2018-3-23 15:46:41 |
| Millisecond | millisecond | int64 | millisecond | 1524472688352 |
| MillisecondFormat | millisecond_format | string | millisecond_format | 2018-3-23 15:46:41.970 |
| Level | level | int | logger level | 1 |
| LevelString | level_string | string | logger level string | Error |
| Body | body | string | logger message body | this is a info log |
| File | file | string | Call the file of the logger | main.go |
| Line | line | int | The number of specific lines to call logger | 64 |
| Function | function | string | The function name to call logger | main.main |
If you want to customize the format of the log output ?
config format:
consoleConfig := &go_logger.ConsoleConfig{ Format: "%millisecond_format% [%level_string%] %body%", } fileConfig := &go_logger.FileConfig{ Format: "%millisecond_format% [%level_string%] %body%", } output:
2018-03-23 14:55:07.003 [Critical] this is a critical log! You can customize the format, Only needs to be satisfied Format: "%Logger Message Alias%"
