- 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")
}
