直接上代码：
func upload(w http.ResponseWriter, r *http.Request) { fmt.Println("method:", r.Method) //获取请求的方法 if r.Method == "GET" {crutime := time.Now().Unix()
h := md5.New()
io.WriteString(h, strconv.FormatInt(crutime, 10))
token := fmt.Sprintf("%x", h.Sum(nil)) t, _ := template.ParseFiles("upload.gtpl")t.Execute(w, token)
} else {r.ParseMultipartForm(32 << 20)
file, handler, err := r.FormFile("uploadfile") if err != nil {fmt.Println(err)
return
}
defer file.Close()
fmt.Fprintf(w, "%v", handler.Header)
f, err := os.OpenFile("./test/"+handler.Filename, os.O_WRONLY|os.O_CREATE, 0666) if err != nil {fmt.Println(err)
return
}
defer f.Close()
io.Copy(f, file)
}
}
func main() { http.HandleFunc("/", upload) err := http.ListenAndServe(":9000", nil) if err != nil { fmt.Println("error:", err)}
}
upload.gtpl文件如下
<html>
<head>
<title>上传文件</title>
</head>
<form enctype="multipart/form-data" action="http://127.0.0.1:9000/upload" method="post">
<input type="file" name="uploadfile" />
<input type="hidden" name="toke" value="{{.}}"/>
<input type="submit" value="upload">
</form>
</body>
