javascript - 在 PythonAnywhere 上托管基于 Tornado 的 Python 应用程序时出现 "Error running WSGI application"

Question

我正在尝试托管来自 Python 和 Virus on Network 库的 Mesa。 Mesa is using Tornado 在服务器上可视化图形。 According to PythonAnywhere ，似乎 Tornado 不是首选，因为它具有异步能力，但在不使用异步功能时它应该仍然可以工作。我是网络托管的初学者，我尝试了以下方法但没有成功。

运行.py

virus_on_network.server import server

app_server = server

if __name__=='__main__':
    app_server.launch()

wsgi.py

import sys
path = '/home/ABC123/mysite/'
if path not in sys.path:
    sys.path.append(path)

import tornado.web
import tornado.wsgi
from run import app_server as app  # noqa

application = tornado.wsgi.WSGIApplication([
    (r"/", app),
])

我得到了一些东西，但 JavaScript 部分似乎没有执行。我确实将 D3.js 文件添加到根目录中。

这就是它应该的样子

我觉得这已经非常接近成功了(我可能是错的)，但我对网络开发还很陌生。任何提示或建议将不胜感激。

编辑:感谢@Ionut_Ticus 和@Filip 的建议，我已经上传了.css 和.js 文件，PythonAnywhere 似乎可以识别它们。它看起来更近了，图表和上面板已更新。但是 slider 丢失了，当我单击开始时，图表没有按预期更新。

Answer 1

如果我正确理解了设置，您希望 Tornado 也为您的静态文件提供服务；为此，您必须让它知道在哪里可以找到它们。
尝试:

application = tornado.wsgi.WSGIApplication(
    [
        (r"/", app),
    ], 
    static_path=YOUR_STATICFILES_PATH
)

正如 @Filip 提到的，PythonAnywhere 似乎可以为您服务 static files也是如此。
