windows或者ubuntu 都可以运行,post body 参数为：image ,上传图片格式为base64,新建一个static文件夹，图片存储在static文件夹中
package main
import (
"fmt"
"net/http"
"log"
"io/ioutil"
"time"
"encoding/base64"
)
func recieveImage(w http.ResponseWriter , r *http.Request){
r.ParseForm()
fmt.Println("path",r.URL.Path)
imagebuff := r.Form["image"]
formatTimeStr:=time.Now().Format("2006-01-02-15-04-05")
fmt.Println(formatTimeStr) //打印结果：2017-04-11 13:30:39
dataTimeString := "static/"+string(formatTimeStr)+".png"
fmt.Println(dataTimeString)
imageString := string(imagebuff[0])
base2Img(imageString,dataTimeString)
fmt.Fprintf(w,"submit sucess!")
}
func base2Img(imageString string,filename string){
ddd, _ := base64.StdEncoding.DecodeString(imageString)
err :=ioutil.WriteFile(filename, ddd, 0666)
fmt.Println(err)
}
func welcomeUse(w http.ResponseWriter , r *http.Request){
r.ParseForm()
fmt.Println("path",r.URL.Path)
fmt.Fprintf(w,"http server!")
}
func main(){
fmt.Println(" welcome to use http server ")
fmt.Println(" ")
http.HandleFunc("/",welcomeUse)
http.HandleFunc("/image/upload",recieveImage)
err := http.ListenAndServe(":8080",nil)
if err != nil{
