Types ¶
type Context ¶
type Context struct {
Request *http.Request
// Value of 'maxMemory' param that is given to http.Request's ParseMultipartForm
// method call.
MaxMultipartMemory int64
}
Context is the most important part of gin. It allows us to pass variables between middleware, manage the flow, validate the JSON of a request and render a JSON response for example.
type Message ¶
type Validate ¶
type Validate struct {
// contains filtered or unexported fields
}
func NewValidate ¶
NewValidate 初始化 Validate
Example ¶
package main
import (
"net/http"
"github.com/gin-gonic/gin"
"github.com/wxw9868/util"
)
type RegisterRequest struct {
Mobile string `json:"mobile" validate:"required,number,len=11" label:"手机号"`
UserType int `json:"user_type" validate:"required,number,len=1" label:"用户类别"`
Captcha
}
type Captcha struct {
VerifyCode string `json:"verify_code" validate:"required,number,len=6" label:"验证码"`
}
func main() {
engine := gin.Default()
engine.POST("/register", register)
_ = engine.Run()
}
func register(c *gin.Context) {
r := new(RegisterRequest)
if err := util.NewValidate("label").StructError(r); err != nil {
c.JSON(http.StatusNotFound, util.Msg(false, 0, err.Error(), nil))
return
}
c.JSON(http.StatusOK, util.Msg(true, 1, "注册成功", nil))
}
Output:
