python - 静态子文件夹中的视频不起作用

Question

我找到了这段代码：

from flask import Flask
import flask
from os import listdir
import os.path
import pathlib
import ntpath


app = Flask(__name__)
@app.route('/', defaults={'req_path': ''})
@app.route('/<path:req_path>')
def dir_listing(req_path):
    BASE_DIR = 'D:/Users/xxx/projects/project1/static'

    # Joining the base and the requested path
    abs_path = os.path.join(BASE_DIR, req_path)

    # Return 404 if path doesn't exist
    if not os.path.exists(abs_path):
        return flask.abort(404)

    # Check if path is a file and serve
    if os.path.isfile(abs_path):
        return flask.send_file(abs_path)

    # Show directory contents
    files = os.listdir(abs_path)
    for i, f in enumerate(files):
        files[i] = os.path.join(req_path, f).replace('\\', '/')
    return flask.render_template('files.html', files=files)


if __name__ == '__main__':
    app.run(host='10.13.0.33', port=80)

以及相应的 index.html：

<ul>
    {% for file in files %}
        <li><a href="{{ file }}">{{ file }}</a></li>
    {% endfor %}
</ul>

在您到达 SecondFolder 之前，它会按预期工作！
呈现的 html 看起来不错：

<ul>
    <li><a href="FirstFolder/SecondFolder/file3.mp4">FirstFolder/SecondFolder/file3.mp4</a></li>
    <li><a href="FirstFolder/SecondFolder/ThirdFolder">FirstFolder/SecondFolder/ThirdFolder</a></li>
</ul>

但是，当我将鼠标悬停在链接上时，我得到了这个（注意第一个文件夹是重复的！）：http: //10.13.0.33/FirstFolder/FirstFolder/SecondFolder/ThirdFolder

原始帖子： 我正在尝试在嵌套文件夹中显示指向视频的链接。每个文件夹中有很多文件（多达 30 个），所以我不想一次下载或播放所有文件。这个想法是让用户看到他们想要查看的内容并单击播放按钮。

这目前正在 PyCharm 中的 Windows 10 上开发/测试。

顶级（主页）页面和下一个文件夹深度按预期运行。当我选择下一个深度文件夹时，视频标记为“无效来源”

深度有限制吗？

这是我的代码：

from flask import Flask
from os import listdir
import os.path
import pathlib
import ntpath


def remove_top_folder(path):
    path_to_file = pathlib.Path(path)
    path_to_file = path_to_file.relative_to(*path_to_file.parts[:1])
    return str(path_to_file).replace('\\', '/')


def get_folders(folder):
    if folder is not None and os.path.isdir(folder):
        folders = []
        for f in listdir(folder):
            path_to_folder = os.path.join(folder, f).replace('\\', '/')
            if os.path.isdir(path_to_folder) and not f.startswith('.'):
                folders.append(remove_top_folder(path_to_folder))
        return folders
    return None


def get_videos(folder):
    if folder is not None and os.path.isdir(folder):
        videos = []
        for f in listdir(folder):
            path_to_video = os.path.join(folder, f).replace('\\', '/')
            if os.path.isfile(os.path.join(folder, f)) and not f.startswith('.') and f.endswith('.mp4'):
                videos.append(path_to_video)
        return videos
    return None


def get_stuff(folder):
    folders = get_folders(folder)
    videos = get_videos(folder)
    if folder == 'static\\' or folder == 'static/':
        rtn = ''
    else:
        rtn = '<H1>{}</H1>'.format(remove_top_folder(folder))
    if videos is not None:
        for file_name in videos:
            file_name = file_name
            rtn += '''

        '''.format(folder, ntpath.basename(folder))
    return rtn


app = Flask(__name__)
@app.route('/', defaults={'u_path': ''})
@app.route('/<path:u_path>')
def catch_all(u_path):
    if u_path is None:
        folder = 'static//'
    elif u_path.endswith('mp4'):
        rtn = '''

        '''.format(u_path, remove_top_folder(u_path))
        return rtn
    else:
        folder = os.path.join('static', u_path).replace('\\', '/')
    stuff = get_stuff(folder)
    html = '''
        <!doctype html>
        <html>
            <body>
                <h1>{0}</h1>

    '''.format(stuff)
    return html


if __name__ == '__main__':
    app.run(host='10.13.0.33', port=80)

我的文件夹看起来像这样：

static
  file_1.mp4
  First_Folder
    file_2.mp4
    Second_folder
      file_3.mp4

当我访问网页时，我得到了这个：

当我单击 FirstFolder 链接时，我得到以下信息：

当我单击 SecondFolder 链接时，我得到了这个：

我让它工作：

应用程序.py：

import flask
import ntpath
import os
import socket

host_name = socket.gethostname()
if host_name == 'hostname1':
    static_folder = '/some/path/to/videos'

    port = 80
elif host_name == "hostname2":
    static_folder = '/another/path/to/videos'
    ip_address = '10.xxx.xxx.xxx'
    port = 8000
else:
    raise Exception('hostname is not defined!')

    return []
