在分块上传的python中的MemoryError

我正在编写分块上传文件的服务器端。 所以有时我得到了MemoryError，我不明白我做错了什么。 这里我的Python代码（与框架金字塔）：

@view_config(route_name='fileupload',renderer='../upload.mako')
def upload_file(request):
    session = request.session
    if 'authorized' in session and session['authorized'] is False:
        return HTTPForbidden()
    try:
        filename = request.params.get('filename')
        print request.params.get('chunkindex')
        datatmp = request.params.get('data')
        data64 = datatmp[13:]
        data = base64.b64decode(data64)
        f = open('/home/somedirectory/' + filename , 'ab')
        f.write(data)
        f.close()
    except Exception as e:
        print e
    return {}

错误追溯：

MemoryError

Pyramid Debugtoolbar在尝试呈现POST请求中的变量时引发此异常。

您可以在开发环境中启用此功能，并禁用它在production.ini中运行您的应用程序。 评估行为是否不同。

BTW：在身份验证上运行金字塔教程，以保护您的视图为经过身份验证的用户，不要以这种方式吞服异常，并使用日志语句而不是打印。 任何金字塔文件/图将应用这些技术。
