gin获取post body

在php里，是通过php://input
在gin中，可以通过c.Request.Body.Read(buf)来获取的

package main

import (
    "fmt"
    "net/http"

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

func main() {
    router := gin.Default()
    router.POST("/events", events)
    router.Run(":5000")
}

func events(c *gin.Context) {
    buf := make([]byte, 1024)
    n, _ := c.Request.Body.Read(buf)
    fmt.Println(string(buf[0:n]))
    resp := map[string]string{"hello": "world"}
    c.JSON(http.StatusOK, resp)
    /*post_gwid := c.PostForm("name")
    fmt.Println(post_gwid)*/
}
