// fileUpload project main.go
package main
import (
"fmt"
"html/template"
"io"
"log"
"net/http"
"os"
)
var buf []byte
func upload(w http.ResponseWriter, r *http.Request) {
r.ParseForm()
if r.Method == "GET" {
t, err := template.ParseFiles("upload.gptl")
checkErr(err)
t.Execute(w, nil)
} else {
file, handle, err := r.FormFile("file")
checkErr(err)
f, err := os.OpenFile("./test/"+handle.Filename, os.O_WRONLY|os.O_CREATE, 0666)
io.Copy(f, file)
checkErr(err)
defer f.Close()
defer file.Close()
fmt.Println("upload success")
}
}
func checkErr(err error) {
if err != nil {
err.Error()
}
}
func main() {
http.HandleFunc("/upload", upload)
err := http.ListenAndServe(":8888", nil)
if err != nil {
log.Fatal("listenAndServe: ", err)
}
}
最主要的其实也就是这两句：
f, err := os.OpenFile("./test/"+handle.Filename, os.O_WRONLY|os.O_CREATE, 0666)
io.Copy(f, file)
执行目录，权限，然后执行copy
upload.gptl文件:
<html> <head></head> <body> <form action="upload" method="post" enctype="multipart/form-data"> <input type="file" name="file" value="" /> <input type="submit" name="submit" /> </form> </body> </html>
如果当前目录下没有test文件夹，不会自动创建。需要手动创建
