Gin框架之参数绑定的实现

package main

import (
	"GitHub.com/gin-Gonic/gin"
	"net/Http"
)

type User struct {
	Username string `json:"user" form:"userform"`
	PassWord string `json:"pwd" form:"pwdform"`
}

func main() {
	r := gin.Default()
	var u User
	//queryString数据绑定
	r.GET("/user", func(c *gin.Context) {
		//参数绑定
		err := c.ShouldBind(&u)
		if err == nil {
			c.JSON(http.StatusOK, gin.H{
				"user": u.Username,
				"pwd":  u.Password,
			})
		}
	})
	//form表单数据绑定
	r.POST("/form", func(c *gin.Context) {
		//参数绑定
		err := c.ShouldBind(&u)
		if err == nil {
			c.JSON(http.StatusOK, gin.H{
				"user": u.Username,
				"pwd":  u.Password,
			})
		}
	})
	//form表单数据绑定
	r.POST("/json", func(c *gin.Context) {
		//参数绑定
		err := c.ShouldBind(&u)
		if err == nil {
			c.JSON(http.StatusOK, gin.H{
				"user": u.Username,
				"pwd":  u.Password,
			})
		}
	})
	r.Run(":9090")
}
