Golang_validator

Freely customizable Golang parameter verifier

About the component:
This component is highly customizable and can be used as an example:

type testValidator struct {    ItemNum int `valid:"PosNO" name:"items" ` // 验证是否是正数    IsCount int `valid:"PosNO"`}

Valid for validation, followed by the name of the function to be validated: This can be written if you want to validate for integers and strings:

`valid:"PosNO，Str"

Name indicates the name of the current field
To extend, verify that the function is in the following format:

 func (this *Validator) CheckPosNO(data int, tag reflect.StructTag) error {     if data <= 0 {         return errors.New(tag.Get("name") + ":不能为负数!")     }     return nil }

The check represents the prefix of the function and is written on the label when called: Posno can

With regard to this component, many of the web frameworks currently Golang are available, but why should the author write it himself for the following reasons:
While many frameworks are available, there is little support for customization. So I wrote one based on the needs of the project.
