使用Bottle框架在Python中通过HTTP发送文件

Question

How can I send a file as answer to an HTTP request in Python using the bottle framework?

For upload this code works for me:

@route('/upload', method='POST')
def do_upload():
    category   = request.forms.get('category')
    upload     = request.files.get('upload')
    name, ext = os.path.splitext(upload.raw_filename)
    if ext not in ('.png','.jpg','.jpeg'):
        return 'File extension not allowed.'

    save_path = category
    upload.raw_filename = "hoho" + ext
    upload.save(save_path) # appends upload.filename automatically
    return 'OK'

Just call Bottle's static_file function and return its result:

@route('/static/<filename:path>')
def send_static(filename):
    return static_file(filename, root='/path/to/static/files')

That example, when called with url /static/myfile.txt , will return the contents file /path/to/static/files/myfile.txt .

Other SO questions (like this one ) contain additional examples.
