## 简介
[](https://pkg.go.dev/github.com/iotames/miniutils)
[](https://github.com/iotames/miniutils/blob/main/LICENSE)
Go实用小工具: 封装了高效开发的常用工具、函数集，简单易用。
## 快速开始
```
# 创建本地项目 myproject
go mod init myproject
# 新建入口文件 main.go
vim main.go
```
入口文件 `main.go`
```
package main
import (
"fmt"
"github.com/iotames/miniutils"
)
func main() {
strfind := miniutils.NewStrfind("https://d.168.com/offer/356789.html")
dofind := strfind.SetRegexp(`offer/(\d+)\.html`).DoFind()
fmt.Println(dofind.GetOne(false)) // "356789"
fmt.Println(dofind.GetOne(true)) // "offer/356789.html"
}
```
```
# 更新依赖
go mod tidy
# 运行
go run .
```
## 示例
[测试样例](/utils_test.go)
### JWT 工具
`JWT`: 全称JSON Web Token，互联网API通讯接口身份验证的行业标准。通过JWT字符串的解密和验签，进行用户身份认证。参见: 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"}
// 设置原始数据jwtInfo，有效期3600秒，创建JWT字符串tokenStr
tokenStr, err := jwt.Create(jwtInfo, time.Second*3600)
if err != nil {
fmt.Printf("jwt.Create error: %v", err)
return
}
log.Println("create JWT:", tokenStr)
// 解码 JWT 字符串. 返回 map[string]interface{} 格式的数据。
info, err := miniutils.NewJwt("").Decode(tokenStr)
if err != nil {
fmt.Printf("jwt.Decode error: %v", err)
return
}
log.Println("jwt Decode:", info)
// 解码 JWT 字符串并验签，验证有效期。 返回 map[string]interface{} 格式的数据。
claims, err := jwt.Parse(tokenStr)
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 := miniutils.GetLogger("")
logger.Debug("first log 11111")
logger.Info("second log 22222")
logger = miniutils.NewLogger("runtime/mylogs")
logger.Debug("my logs 2333")
logger.CloseLogFile()
```
### 字符串提取工具
```
strfind := miniutils.NewStrfind("https://d.168.com/offer/356789.html")
dofind := strfind.SetRegexp(`offer/(\d+)\.html`).DoFind()
fmt.Println(dofind.GetOne(false)) // "356789"
fmt.Println(dofind.GetOne(true)) // "offer/356789.html"
```
### HTTP请求工具
```
// 构建HTTP请求(默认GET方法)
req := miniutils.NewHttpRequest("https://httpbin.org/get")
// 设置HTTP请求头
req.SetRequestHeader("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.81 Safari/533.33")
// 执行HTTP请求
err := req.Do(nil)
if err != nil {
log.Println(err)
}
// 打印响应内容消息体
log.Println(string(req.BodyBytes))
req = miniutils.NewHttpRequest("https://httpbin.org/post")
// 构建POST请求
req.SetRequestPostByString("hello=word&some=2333")
// 执行HTTP请求
req.SetRequestHeader("xkey", "secretttkeyyy")
err = req.Do(nil)
if err != nil {
log.Printf("request post do err (%v) \n", err)
}
// 打印HTTP响应对象
log.Println(*req.Response)
// 下载图片到本地
miniutils.NewHttpRequest("https://www.baidu.com/img/PCtm_d9c8750bed0b3c7d089fa7d55720d6cf.png").Download("runtime/baidu.png")
