Gin之获取JSON参数

• Gin之获取JSON参数
• • 1.获取JSON参数(ShouldBind方法)
  • 2.获取JSON参数(ShouldBind方法)
  • 3.获取JSON参数(ShouldBind方法)
  • 4.获取JSON参数(ShouldBind方法)
  • 5.获取JSON参数(ShouldBind方法)

注：本文基于Windos系统上Go SDK v1.17.5、github.com/gin-gonic/gin v1.7.7依赖进行讲解

package main

import (
   "fmt"
   "github.com/gin-gonic/gin"
   "net/http"
)

type UserInfo struct {
   Username string `form:"username" json:"user"`
   Password string `form:"password" json:"pass"`
}

func main() {
   r := gin.Default()
   r.POST("/user", func(c *gin.Context) {
   	var u UserInfo
   	err := c.ShouldBind(&u)
   	if err != nil {
   		c.JSON(http.StatusBadRequest, gin.H{
   			"error": err.Error(),
   		})
   	} else {
   		fmt.Printf("%#vn", u)
   		c.JSON(http.StatusOK, gin.H{
   			"status": "ok",
   		})
   	}
   })
   r.Run()
}

注：raw代表的是原始数据，这四行内容是自己写进去的

package main

import (
	"github.com/gin-gonic/gin"
	_ "github.com/gin-gonic/gin/binding"
	"log"
)

type Person struct {
	Name    string `json:"name"`
	Address string `json:"address"`
}

func startPage(c *gin.Context) {
	var person Person
	if c.ShouldBind(&person) == nil {
		log.Println(person.Name)
		log.Println(person.Address)
	}
	c.String(200, "Success")
}
func main() {
	r := gin.Default()

	r.POST("/user", startPage)
	r.Run()
}

package main

	"fmt"

type UserInfo struct {

	Password string `form:"password"`
}

func main() {

		if err != nil {

		}
	})
	r.Run()
