go-playground / validator作为一款优秀的Go语言校验库,基于标记为结构体和单个字段实现值验证。使用简单、快捷。 添加依赖 gogetgithub.com/go-playground/validator 1. 代码 packagemain import( "fmt" "github.com/go-playground/validator" ) varvalidate*validator.Validate//定义 typeUserstruct{ Namestring`valida...
go get github.com/go-playground/validator/v10 Then import the validator package into your own code. import "github.com/go-playground/validator/v10" Error Return Value Validation functions return type error They return type error to avoid the issue discussed in the following, where err is al...
使用validator validator的自定义校验规则用起来麻烦,看下面的官方例子,自定义了一个is-awesome的校验标签。 packagemainimport("fmt""github.com/go-playground/validator/v10")// MyStruct ..typeMyStructstruct{Stringstring`validate:"is-awesome"`}// use a single instance of Validate, it caches struct info...
