git@gitee.com:DanYuJie/upanddown.git這里我們使用flask框架，簡單實用
目錄結構： upandown/static/css/js/jquery.min.jstoastr.min.jstemplates/index.htmltest.py首先我們需要一個頁面在templates/index.html(這里使用form表單實現)
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><meta http-equiv="X-UA-Compatible" content="ie=edge"><link rel="stylesheet" href="../static/css/toastr.min.css"><script src="../static/js/jquery.min.js"></script><script src="../static/js/toastr.min.js"></script><title>Document</title> </head> <body><form method="POST" action="/upload" enctype="multipart/form-data"><input type="file" name="file" id="file"><input type="submit" value="upload"><a href=""></a></form><hr><ol id="filelist"></ol><script>function checkstatus(){if('{{status}}'== 'OK'){toastr['success']("上傳成功");}else if('{{status}}'== 'null'){toastr['error']("上傳失敗"); }}function get_list(){$.ajax({url:'/getlist',type:'GET',success:function(result){len_result = result.length;for(var x =0; x < len_result; x++){$("#filelist").append('<br><a href=/download/' + result[x] + '>' + result[x] +'</a>');}alert(content_list);},error:function(){alert("失敗");}});}checkstatus();get_list();</script> </body> </html>然后是后臺接收
test.py
