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
