gotool

gotool是一个小而全的Golang工具集，主要是将日常开发中常用的到方法进行提炼集成，避免重复造轮子，提高工作效率，每一个方法都是作者经过工作经验，和从以往的项目中提炼出来的。

2021-7-9更新内容详细使用请看文档

添加文件IO操作工具FileUtils
添加验证码生成工具CaptchaUtils
添加文件目录压缩和解压缩工具ZipUtis

Logs 日志打印工具

1、gotool.Logs.ErrorLog 异常日志

2、gotool.Logs.InfoLog 加载日志

3、gotool.Logs.DebugLog 调试日志

func TestLogs(t *testing.T) {
gotool.Logs.ErrorLog().Println("Error日志测试")
gotool.Logs.InfoLog().Println("Info日志测试")
gotool.Logs.DebugLog().Println("Debug日志测试")

PageUtils 分页工具

1、gotool.PageUtils.Paginator 彩虹分页

func TestPage(t *testing.T) {
paginator := gotool.PageUtils.Paginator(5, 20, 500)
fmt.Println(paginator)
}
//out

//说明 AfterPage 下一页  beforePage前一页 currPage当前页 pages页码 totalPages总页数

IdUtils

id生成工具，可生成字符串id和int类型id，根据需要选择自己需要的生成规则

1、gotool.IdUtils.IdUUIDToTime 根据时间生成的UUID规则，入参 true消除“-”false保留“-”

func TestUUID(t *testing.T) {
time, err := gotool.IdUtils.IdUUIDToTime(true)
if err == nil {
fmt.Println("根据时间生成UUID去除--------------------->'-'----->", time)
}
time, err = gotool.IdUtils.IdUUIDToTime(false)
if err == nil {
fmt.Println("根据时间生成不去除--------------------->'-'----->", time)
}
}
//out
== = RUN   TestUUID
根据时间生成UUID去除--------------------->'-'-----> 6fb94fe4dfd511ebbc4418c04d462680
根据时间生成不去除--------------------->'-'-----> 6fb9c783-dfd5-11eb-bc44-18c04d462680
--- PASS: TestUUID (0.00s)
PASS

2、gotool.IdUtils.IdUUIDToRan 根据随机数生成的UUID推荐使用本方法，并发不会出现重复现象入，参 true消除“-”false保留“-”

    time, err := gotool.IdUtils.IdUUIDToTime(true)
if err == nil {
fmt.Println("根据时间生成UUID去除--------------------->'-'----->", time)
}
time, err = gotool.IdUtils.IdUUIDToTime(false)

--- PASS: TestUUID (0.00s)
PASS

3、gotool.IdUtils.CreateCaptcha 生成随机数id，int类型，入参int 1-18，超过18后会造成int超过长度

func TestCreateCaptcha(t *testing.T) {
captcha, err := gotool.IdUtils.CreateCaptcha(18)
if err != nil {
fmt.Println(err)
}
fmt.Println("18位------------------------------------------>", captcha)
captcha, err = gotool.IdUtils.CreateCaptcha(10)
if err != nil {
fmt.Println(err)
}
fmt.Println("10位------------------------------------------>", captcha)
}
//out

4、gotool.IdUtils.GetIdWork根据时间戳在加以计算获取int64的id 长度16位

func TestGetIdWork(t *testing.T) {
work := gotool.IdUtils.GetIdWork()
fmt.Println("根据时间戳在加以计算获取int64类型id-------->", work)
}
//out

HttpUtils

golang 的一个简单的“HTTP 请求”包 GET POST DELETE PUT

我们如何使用HttpUtils？

resp, err := gotool.HttpUtils.Get("http://127.0.0.1:8000")
resp, err := gotool.HttpUtils.SetTimeout(5).Get("http://127.0.0.1:8000")
resp, err := gotool.HttpUtils.Debug(true).SetHeaders(map[string]string{}).Get("http://127.0.0.1:8000")

OR

req := gotool.HttpUtils.NewRequest()
req := gotool.HttpUtils.NewRequest().Debug(true).SetTimeout(5)
resp, err := req.Get("http://127.0.0.1:8000")
resp, err := req.Get("http://127.0.0.1:8000",nil)
resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest")
resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest", "address=beijing")

设置请求头

req.SetHeaders(map[string]string{
"Content-Type": "application/x-www-form-urlencoded",
"Connection": "keep-alive",
})

req.SetHeaders(map[string]string{

return string(body)

提示模式

默认 false

req.Debug(true)

以标准输出打印：

[HttpRequest]

Headers: map[Content-Type:application/x-www-form-urlencoded]
Cookies: map[]
Timeout: 30s
ReqBody: map[age:19 score:100]
-------------------------------------------------------------------

Json

Post JSON 请求

设置请求头

 req.SetHeaders(map[string]string{"Content-Type": "application/json"})

Or

req.JSON().Post("http://127.0.0.1:8000", map[string]interface{}{
"id":    10,
"title": "github",
})

req.JSON().Post("http://127.0.0.1:8000", "{\"title\":\"github\",\"id\":10}")

Post 请求

resp, err := req.Post("http://127.0.0.1:8000", map[string]interface{}{
"id":    10,
"title": "HttpRequest",
})

打印格式化的 JSON

str, err := resp.Export()
if err != nil {
return
}

解组 JSON

var u User
err := resp.Json(&u)
if err != nil {
return err
}

var m map[string]interface{}
err := resp.Json(&m)
if err != nil {
return err
}

gotool

2021-7-9更新内容详细使用请看文档

如何使用gotool呢？

安装

引入

StrUtils

1、gotool.StrUtils.ReplacePlaceholder 占位符替换

2、gotool.StrUtils.RemoveSuffix 去除文件扩展名获取文件名

3、gotool.StrUtils.GetSuffix 获取文件扩展名

4、gotool.StrUtils.HasEmpty 判断字符串是否未空，我空返回ture

StrArrayUtils string数组操作工具

1、gotool.StrArrayUtils.StringToInt64 字符串数组转int64数组，调用前请确保字符串数组均为数字

2、gotool.StrArrayUtils.StringToInt32 字符串数组转int64数组，调用前请确保字符串数组均为数字

3、gotool.StrArrayUtils.ArrayDuplication 数组去重

DateUtil

1、gotool.DateUtil.FormatToString 时间格式化成字符串

2、gotool.DateUtil.IsZero 判断时间是否为空

3、gotool.DateUtil.Now 获取当前时间 等同于time.Now(),为了统一化所以将此方法也纳入到工具中

4、gotool.DateUtil.InterpretStringToTimestamp 字符串格式化成时间类型

5、gotool.DateUtil.UnixToTime 时间戳转时间

6、gotool.DateUtil.GetWeekDay 获取星期几

7、gotool.DateUtil.MinuteAddOrSub,HourAddOrSub,DayAddOrSub 时间计算工具

ConvertUtils 公历转农历工具

1、gotool.ConvertUtils.GregorianToLunarCalendar(公历转农历),GetLunarYearDays(农历转公历),GetLunarYearDays(获取农历这一年农历天数)

2、gotool.ConvertUtils.GetSolarMonthDays(2021,7)获取公历某月天数 2021年7月天数

3、gotool.ConvertUtils.IsLeapYear(2021)获取某年是否是瑞年 true是 false不是

4、gotool.ConvertUtils.GetLeapMonth(2021)获取某年闰月月份

BcryptUtils 加密和解密工具

1、gotool.BcryptUtils.Generate 加密处理，多用于密码进行加密后数据库存储使用，不可逆

2、gotool.BcryptUtils.CompareHash 加密后和未加密密码对比，多用于登录验证使用

3、gotool.BcryptUtils.MD5 md5加密

4、gotool.BcryptUtils.GenRsaKey(获取公钥和私钥),

5、RsaSignWithSha256(进行签名),

6、RsaVerySignWithSha256(验证),

2、gotool.FileUtils.IsDir 判断是否是目录

3、gotool.FileUtils.IsFile 判断是否是文件

4、gotool.FileUtils.RemoveFile 删除文件或目录
