之前用python -m SimpleHTTPServer 命令快速起一个webserver还是觉得很好用的,但是缺少upload 的功能颇感遗憾。 最近研究Flask-Admin 的时候发现有个 FileAdmin的class,挺适合做文件服务器的。
Flask-Admin github: https://github.com/flask-admin/flask-admin
安装flask-admin命令:
pip install flask-admin
代码如下:
from flask_admin.contrib.fileadmin import FileAdmin
from flask_admin import Admin
from flask import Flask
import os
from flask_script import Shell, Manager
app=Flask(__name__)
# get base location of current file
basedir=os.path.abspath(os.path.dirname(__file__))
# app configuration
app.config['SECRET_KEY']='!@$RFGAVASDGAQQQ'
admin = Admin(app, name='File', template_mode='bootstrap3')
path=os.path.join(basedir, 'static')
admin.add_view(FileAdmin(basedir, name='Static Files'))
manager = Manager(app)
manager.run()
略微有个小遗憾,在显示文件只有Name 和Size,并没有文件的修改时间。我看了下源代码, 发现get_files
函数其实是有收集修改时间的 op.getmtime(fp)
,只是没有暴露出来
def get_files(self, path, directory):
"""
Gets a list of tuples representing the files in the `directory`
under the `path`
:param path:
The path up to the directory
:param directory:
The directory that will have its files listed
Each tuple represents a file and it should contain the file name,
the relative path, a flag signifying if it is a directory, the file
size in bytes and the time last modified in seconds since the epoch
"""
items = []
for f in os.listdir(directory):
fp = op.join(directory, f)
rel_path = op.join(path, f)
is_dir = self.is_dir(fp)
size = op.getsize(fp)
last_modified = op.getmtime(fp)
items.append((f, rel_path, is_dir, size, last_modified))
return items
修改list.html 加入一行即可
<table class="table table-striped table-bordered model-list">
<thead>
<tr>
{% block list_header scoped %}
{% if actions %}
<th class="list-checkbox-column">
<input type="checkbox" name="rowtoggle" class="action-rowtoggle" />
</th>
{% endif %}
<th class="col-md-1"> </th>
<th>{{ _gettext('Name') }}</th>
<th>{{ _gettext('Size') }}</th>
<th>{{ _gettext('Date') }}</th>
{% endblock %}
</tr>
</thead>
...
<td>
{{ size|filesizeformat }}
</td>
<td>
{{date|datetime}}
</td>
其中 <th>{{ _gettext('Date') }}</th>
和 {{date|datetime}}
是我手动添加的 。 用到了一个customized datetime的filter,因为last_modified = op.getmtime(fp)
返回的是一个float类型变量,需要进行转换成更可读的时间, 代码如下
def format_datetime(value):
"""
define a filters for jinjia2 to format the unix timestamp (float) to humman readabl
"""
return datetime.fromtimestamp(value).strftime('%Y-%m-%d %H:%M:%S')
#set the filter we just created
env = app.jinja_env
env.filters['datetime'] = format_datetime
如何通过curl 命令上传文件到这个webserver上呢,可以参考下面的例子
curl -F "upload=@c:\b.txt" http://localhost:5000/admin/fileadmin/upload/
