python - 使用 Bottle 框架在 Python 中通过 http 发送文件

Question

如何使用 bottle 框架在 Python 中发送文件作为 HTTP 请求的应答？

对于上传，此代码对我有用:

@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'

Answer 1

只需调用 Bottle's static_file function并返回结果:

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

该示例，当使用 url /static/myfile.txt 调用时，将返回内容文件 /path/to/static/files/myfile.txt。

其他 SO 问题(如 this one)包含其他示例。
