Gin

• 當要綁定 query param 時，struct tag 用 form
• 當要綁定 body 時，struct tag 用 json

package main

import (
    "fmt"
    "net/http"

    "github.com/gin-gonic/gin"
)

func main() {
    route := gin.Default()
    route.GET("/", test)
    route.POST("/", test)
    route.Run(":8000")
}

type Student struct {
    Name string `form:"name"`
    Age  int    `form:"age"`
}

func test(c *gin.Context) {
    var student Student

    err := c.ShouldBind(&student)
    if err != nil {
        fmt.Println("error: " + err.Error())
    }

    fmt.Printf("name: %v\n", student.Name)
    fmt.Printf("age: %v\n", student.Age)

    c.JSON(200, gin.H{"msg": http.StatusOK})
}
