Python - 利用flask搭建一个共享服务器
零、概述
我利用flask搭建了一个简易的共享服务器，分享给大家
一、python代码
import os
import time
from flask import Flask,render_template,url_for,redirect,send_from_directory
# 共享文件夹的根目录
rootdir = r'C:\Users\Administrator\Downloads\zlkt'
app = Flask(__name__)
@app.route('/doc/')
@app.route('/doc/<subdir>/')
def document(subdir=''):
if subdir == '':
# 名字为空，切换到根目录
os.chdir(rootdir)
else:
fullname = rootdir + os.sep + subdir
# 如果是文件，则下载
if os.path.isfile(fullname):
return redirect(url_for('downloader', fullname=fullname))
# 如果是目录，切换到该目录下面
else:
os.chdir(fullname)
current_dir = os.getcwd()
current_list = os.listdir(current_dir)
contents = []
for i in sorted(current_list):
fullpath = current_dir + os.sep + i
# 如果是目录，在后面添加一个sep
if os.path.isdir(fullpath):
extra = os.sep
else:
extra = ''
content = {}
content['filename'] = i + extra
content['mtime'] = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(os.stat(fullpath).st_mtime))
content['size'] = str(round(os.path.getsize(fullpath) / 1024)) + 'k'
contents.append(content)
return render_template('test.html', contents=contents, subdir=subdir, ossep=os.sep)
@app.route('/download/<fullname>')
def downloader(fullname):
filename = fullname.split(os.sep)[-1]
dirpath = fullname[:-len(filename)]
return send_from_directory(dirpath, filename, as_attachment=True)
if __name__ == '__main__':
app.run()
二、html代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>文档管理</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css"
integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u"
crossorigin="anonymous">
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap-theme.min.css"
integrity="sha384-rHyoN1iRsVXV4nD0JutlnGaslCJuC7uwjduW9SVrLvRYooPp2bWYgmgJQIXwl/Sp"

integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa"
crossorigin="anonymous"></script>
<style type="text/css">
.big-border {
background: #fff;
width: 1400px;
margin: 0 auto;
padding: 10px;
}
body {
background: #f3f3f3;
}
.page-title {
text-align: center;
}
</style>
</head>
<body>
<div class="big-border">
<h3 class="page-title">文档管理</h3>
<hr>
<h4>当前目录 {{ossep+subdir}}</h4>
<hr>
<table width="600px">
<thead>
<tr>
<th>文件或目录名</th>
<th>修改时间</th>
<th>大小</th>
</tr>
</thead>
<tbody>
{% if subdir %}
<tr>
<td><a href="../">..{{ossep}}</a></td>
<td></td>
<td></td>
</tr>
{% endif %}
{% for i in contents %}
<tr>
<td><a href="{{ url_for('document', subdir=subdir+i.filename) }}">{{ i.filename }}</a></td>
<td>{{ i.mtime }}</td>
<td>{{ i.size }}</td>
</tr>
{% endfor %}
</tbody>
</table>
<hr>
</div>
</body>
</html>
三、使用
1. 更改python代码中的rootdir，这里需要填你所共享的文件夹
2. render_template('test.html', ...)，我将html命名为test.html，所以这里就是render_template('test.html', ...)，你如果命名了其它名字，这里记得改一下
四、最后效果
运行脚本之后，用浏览器打开 http://127.0.0.1:5000/doc/，显示效果如下图
最后欢迎大家使用，和我交流。
