如果同时地用binding:"required",绑定时具有空值,将返回错误。 // Binding from JSONtypeLoginstruct{Userstring`form:"user" json:"user" xml:"user" binding:"required"`Passwordstring`form:"password" json:"password" xml:"password" binding:"required"`}funcmain(){router:=gin.Default()// Example for ...

在Golang 语言中,我们可以使用反单引号为 Struct 中的字段设置 Tag,通过 Tag 可以为 Struct 中的字段定义附加属性。Tag 实际上就是一个字符串,只不过有特定的格式,也就是说 Tag 字符串必须由key:"value"组成,key 必须是非空字符串,value 必须由双引号引起来。 其中,每个 key 都是一个非空字符串,由除空格...

你还可以给字段指定特定规则的修饰符,如果一个字段用binding:"required"修饰,并且在绑定时该字段的值为空,那么将返回一个错误。 package main import ("net/http""github.com/gin-gonic/gin") type Personstruct{ Namestring`json:"name"binding:"required"`//json格式从name取值,并且该值为必须的Ageint`json:...
