## 脱敏 Desensitization

### 作用 Effect
利用反射处理结构体，处理带`sen`标签的字段(规则: `规则名称,占位符`，如:`phone,*`)，将其脱敏。支持自定义处理函数

Use reflection to process the structure, process the fields with the `sen` tag (rule: `rule name, placeholder`, such as: `phone,*`), and desensitize it. Support custom handlers


### 定义结构体示例 Example
```go
package main

import (
    "github.com/lixh00/sensitive"
)


type User struct {
    Name string `json:"name"`
    Age int `json:"age"`
    Phone string `json:"phone" sen:"phone,*"`
	Email string `json:"email" sen:"email,*"`
}

data :=  User{
    Name: "lixh",
    Age: 18,
	Phone: "13888888888",
	Email: "lixh@gmail.com",
}

// 添加自定义处理函数
// Add custom handler
sensitive.AddHandler("email", func(src, p string) string {
	// 将@符号后面的替换为*
	// Replace the after @ sign with *
	idx := strings.Index(src, "@")
	dst := src[:idx+1] + strings.Repeat(p, utf8.RuneCountInString(src)-idx-1)

	return dst
})

if err := sensitive.Desensitize(data); err != nil {
    fmt.Println(err)
}
bs, _ := json.Marshal(response)
log.Printf("after processing data: %v", string(bs))
```
