Multipart/Urlencoded binding

  1. package main
  3. import (
  4.     "github.com/gin-gonic/gin"
  5. )
  7. type LoginForm struct {
  8.     User     string `form:"user" binding:"required"`
  9.     Password string `form:"password" binding:"required"`
  10. }
  12. func main() {
  13.     router := gin.Default()
  14.     router.POST("/login", func(c *gin.Context) {
  15.         // you can bind multipart form with explicit binding declaration:
  16.         // c.ShouldBindWith(&form, binding.Form)
  17.         // or you can simply use autobinding with ShouldBind method:
  18.         var form LoginForm
  19.         // in this case proper binding will be automatically selected
  20.         if c.ShouldBind(&form) == nil {
  21.             if form.User == "user" && form.Password == "password" {
  22.                 c.JSON(200, gin.H{"status": "you are logged in"})
  23.             } else {
  24.                 c.JSON(401, gin.H{"status": "unauthorized"})
  25.             }
  26.         }
  27.     })
  28.     router.Run(":8080")
  29. }

Test it with:

  1. $ curl -v --form user=user --form password=password http://localhost:8080/login
