這篇文章主要介紹了Python 利用flask搭建一個共享服務(wù)器的步驟，幫助大家更好的理解和學習python，感興趣的朋友可以了解下

零、概述

我利用flask搭建了一個簡易的共享服務(wù)器，分享給大家

一、python代碼

import os
import time
from flask import Flask,render_template,url_for,redirect,send_from_directory
# 共享文件夾的根目錄
rootdir = r'C:\Users\Administrator\Downloads\zlkt'
 
app = Flask(__name__)
 
@app.route('/doc/')
@app.route('/doc/<subdir>/')
def document(subdir=''):
    if subdir == '':
        # 名字為空，切換到根目錄
        os.chdir(rootdir)
    else:
        fullname = rootdir + os.sep + subdir
        #  如果是文件，則下載
        if os.path.isfile(fullname):
            return redirect(url_for('downloader', fullname=fullname))
        #  如果是目錄，切換到該目錄下面
        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
        # 如果是目錄，在后面添加一個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代碼

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>文檔管理</title>
    <link rel="stylesheet"  rel="external nofollow" 
       integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u"
       crossorigin="anonymous">
    <link rel="stylesheet"  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">文檔管理</h3>
    <hr>
    <h4>當前目錄 {{ossep+subdir}}</h4>
    <hr>
    <table width="600px">
      <thead>
        <tr>
          <th>文件或目錄名</th>
          <th>修改時間</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代碼中的rootdir，這里需要填你所共享的文件夾

2. render_template('test.html', ...)，我將html命名為test.html，所以這里就是render_template('test.html', ...)，你如果命名了其它名字，這里記得改一下

四、最后效果

運行腳本之后，用瀏覽器打開 http://127.0.0.1:5000/doc/，顯示效果如下圖
