这里我们使用flask框架，简单实用
目录结构： upandown/ static/ css/ js/ jquery.min.js toastr.min.js templates/ index.html test.py

首先我们需要一个页面在templates/index.html(这里使用form表单实现)
<!DOCTYPE html>
<html>
<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']("上传成功");
}else if('{{status}}'== 'null'){
toastr['error']("上传失败");
}
}
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("失败");
}
});
}
checkstatus();
get_list();
</script>
</body>
</html>
然后是后台接收
test.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from flask import Flask,render_template, request, send_from_directory,jsonify, redirect
import os
# import sys
# reload(sys)
# sys.setdefaultencoding('utf-8')
app = Flask(__name__)
# ALLOWED_EXTENSTIONS = set(['png', 'jpg', 'jpeg', 'gif'])
app.config['UPLOAD_FOLDER'] = os.getcwd()
download_floder = app.config['UPLOAD_FOLDER'] + '/upload'
def allow_file(filename):
allow_list = ['png', 'PNG', 'jpg', 'doc', 'docx', 'txt', 'pdf', 'PDF', 'xls', 'rar', 'exe', 'md', 'zip']
a = filename.split('.')[1]
if a in allow_list:
return True
else:
return False
@app.route('/main')
def home():
return render_template('index.html')
@app.route('/getlist')
def getlist():
file_url_list = []
file_floder = app.config['UPLOAD_FOLDER'] + '/upload'
file_list = os.listdir(file_floder)
for filename in file_list:
file_url = url_for('download',filename=filename)
file_url_list.append(file_url)
# print file_list
return jsonify(file_list)
@app.route('/download/<filename>')
def download(filename):
return send_from_directory(download_floder,filename, as_attachment=True)
@app.route('/upload', methods=['POST', 'GET'])
def upload():
file = request.files['file']
if not file:
return render_template('index.html', status='null')
# print type(file)
if allow_file(file.filename):
file.save(os.path.join(app.config['UPLOAD_FOLDER']+'/upload/', file.filename))
return render_template('index.html', status='OK')
else:
return 'NO'
if __name__ == '__main__':
app.run(debug=True, host='0.0.0.0')
