Go实用小工具
为提高开发效率封装了一些实用工具、函数集，不依赖第三方库。 简单易用，拿来做Golang入门练习也不错。
示例
JWT 工具
JWT: https://jwt.io/
package main
import (
"fmt"
"log"
"time"
"github.com/iotames/miniutils"
)
func main() {
secret := miniutils.GetRandString(32) // 设置JWT签名密钥
jwt := miniutils.NewJwt(secret) // 初始化JWT小工具
jwtInfo := map[string]interface{}{"id": 1519512704946016256, "name": "Harvey", "age": 16, "mobile": "15988888888"}
tokenStr, err := jwt.Create(jwtInfo, time.Second*3600) // 设置原始数据jwtInfo，有效期3600秒，创建JWT字符串tokenStr
if err != nil {
fmt.Printf("jwt.Create error: %v", err)
return
}
log.Println("create JWT:", tokenStr)
info, err := miniutils.NewJwt("").Decode(tokenStr) // 解码 JWT 字符串. 返回 map[string]interface{} 格式的数据。
if err != nil {
fmt.Printf("jwt.Decode error: %v", err)
return
}
log.Println("jwt Decode:", info)
claims, err := jwt.Parse(tokenStr) // 解码 JWT 字符串并验签，验证有效期。 返回 map[string]interface{} 格式的数据。
if err != nil {
fmt.Printf("jwt.Parse error: %v", err)
return
}
log.Println("jwt Parse:", claims)
_, err = jwt.Parse(tokenStr + "sign error")
if err == miniutils.ErrTokenSign {
fmt.Printf("JWT 签名错误")
}
}
日志记录
logger := GetLogger("")
logger.Debug("first log 11111")
logger.Info("second log 22222")
logger = NewLogger("runtime/mylogs")
logger.Debug("my logs 2333")
logger.CloseLogFile()
