Gin 使用方法

  1. 基础用法：
package main

import (
	"net/http"

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

func main() {
	r := gin.Default()

	r.GET("/", func(c *gin.Context) {
		c.String(200, "Index")
	})

	r.GET("/user/:name", func(c *gin.Context) {
		name := c.Param("name")
		c.String(http.StatusOK, "Hello %s", name)
	})

	r.POST("/form", func(c *gin.Context) {
		username := c.PostForm("username")
		password := c.DefaultPostForm("password", "000000")

		c.JSON(http.StatusOK, gin.H{
			"username": username,
			"password": password,
		})
	})

	r.POST("/upload", func(c *gin.Context) {
		file, _ := c.FormFile("file")
		// c.SaveUploadedFile(file, dst)
		c.String(http.StatusOK, "%s uploaded!", file.Filename)
	})

	r.Run("0.0.0.0:8800")
}
