Python 利用flask搭建一个共享服务器的步骤
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" rel="external nofollow" 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" rel="external nofollow" integrity="sha384-rHyoN1iRsVXV4nD0JutlnGaslCJuC7uwjduW9SVrLvRYooPp2bWYgmgJQIXwl/Sp" crossorigin="anonymous"> <script src="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/js/bootstrap.min.js" 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="../" rel="external nofollow" >..{{ossep}}</a></td> <td></td> <td></td> </tr> {% endif %} {% for i in contents %} <tr> <td><a href="{{ url_for('document', subdir=subdir+i.filename) }}" rel="external nofollow" >{{ 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。
