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",

TreeUtils

在gotool中实现了快捷菜单树的生成，包括菜单节点的选中状态、半选状态、菜单的搜索。

该工具提供了两种方法

1、gotool.TreeUtils.GenerateTree(nodes, selectedNodes []INode) (trees []Tree)

GenerateTree 自定义的结构体实现 INode 接口后调用此方法生成树结构。

2、gotool.TreeUtilsFindRelationNode(nodes, allNodes []INode) (respNodes []INode)

FindRelationNode 在 allNodes 中查询 nodes 中节点的所有父子节点返回 respNodes(包含 nodes ，跟其所有父子节点)

DesensitizedUtils

在数据处理或清洗中，可能会涉及到很多隐私信息的脱敏，所gotool封装了一些常用信息的脱敏方法。

提供两个函数方法

1、gotool.DesensitizedUtils.DefaultDesensitized(str string) (result string)

中国身份证、手机、身份证脱敏
一般邮箱脱敏

func TestDesensitized(t *testing.T) {
	//邮箱脱敏
	mail := "testhello@gmail.com"
	star := gotool.DesensitizedUtils.DefaultDesensitized(mail)
	fmt.Println("mail-------------------->", star)
	//手机脱敏
	phone := "13333333333"
	desensitized := gotool.DesensitizedUtils.DefaultDesensitized(phone)
	fmt.Println("phone------------------->", desensitized)
}
//out
=== RUN   TestDesensitized
邮箱--------------------> tes***@gmail.com
手机-------------------> 133****3333
--- PASS: TestDesensitized (0.00s)
PASS

1、gotool.DesensitizedUtils.CustomizeHash(str string, start int, end int) string

自定义脱敏
str要脱敏的数据
start 开始位置
end 结束位置

func TestDesensitized(t *testing.T) {
	//customize desensitization
	customize := "sadasdasdkljkldfjlkdjflkjsdf"
	hideStar := gotool.DesensitizedUtils.CustomizeHash(customize, 4, 14)
	fmt.Println("customize--------------->", hideStar)
}
//out
=== RUN   TestDesensitized
customize---------------> sada**********dfjlkdjflkjsdf
--- PASS: TestDesensitized (0.00s)
PASS

PrettyUtils

PrettyUtils 是一个 gotool 包，它提供了格式化 JSON 以提高可读性的方法，或者为较小的有效负载压缩 JSON。

Pretty

使用这个例子：

{"name":  {"first":"Tom","last":"Anderson"},  "age":37,
"children": ["Sara","Alex","Jack"],
"fav.movie": "Deer Hunter", "friends": [
    {"first": "Janet", "last": "Murphy", "age": 44}
  ]}

以下代码：

result = PrettyUtils.Pretty(example)

将 json 格式化为：

{
  "name": {
    "first": "Tom",
    "last": "Anderson"
  },
  "age": 37,
  "children": ["Sara", "Alex", "Jack"],
  "fav.movie": "Deer Hunter",
  "friends": [
    {
      "first": "Janet",
      "last": "Murphy",
      "age": 44
    }
  ]
}

Color

颜色将为输出到屏幕的 json 着色。

result = PrettyUtils.Color(json, nil)

将为打印到终端的结果添加颜色。第二个参数用于自定义样式，传递 nil 将使用默认的 pretty.TerminalStyle。

Ugly

以下代码：

result = PrettyUtils.Ugly(example)

将 json 格式化为：

{"name":{"first":"Tom","last":"Anderson"},"age":37,"children":["Sara","Alex","Jack"],"fav.movie":"Deer Hunter","friends":[{"first":"Janet","last":"Murphy","age":44}]}```

定制输出

有一个 PrettyOptions(json, opts) 函数，它允许使用以下选项自定义输出：

type Options struct {
    // 宽度是单行数组的最大列宽
    // 默认值为 80
	Width int
    // 前缀是所有行的前缀
    // 默认为空字符串
	Prefix string
	// Indent 是嵌套的缩进
	// 默认为两个空格
	Indent string
	// SortKeys 将按字母顺序对键进行排序
	// 默认为假
	SortKeys bool
}
