python - 在没有 TCP 端口的情况下通过 Flask 调度 URL

Question

我想构建一个混合应用程序(嵌入到桌面应用程序中的 Web 技术)。

我将从 Web 版本开始，并使用 WebKit 嵌入它，但我不希望嵌入版本通过 TCP 端口服务请求。

使用 WebKit(Qt、Gtk)，我可以拦截所有 URL 请求并对其进行操作。

我缺少的是一种无需通过 TCP(或 WSGI)即可调用 Flask URL 可调用调度程序的方法。

还有比使用调试器分析调用堆栈更好的想法吗？

Simon Sapin 在(相当活跃的)Flask 邮件列表上回复:

Why not WSGI ?

You have to get a Python interpreter somewhere. Then you need to call your application somehow with data from WebKit like the URL being requested, and get the response. WSGI is just that: a calling convention for Python functions (or other callable objects.)

If WSGI is more complex than you’d like, you can use the test client:

• http://flask.pocoo.org/docs/api/#flask.Flask.test_client
• http://werkzeug.pocoo.org/docs/test/#werkzeug.test.Client
• http://werkzeug.pocoo.org/docs/test/#werkzeug.test.EnvironBuilder

That’s how I do it in Frozen-Flask. It simulates HTTP requests to a Flask app at the WSGI level and write the responses to static files. The test client is just an easier way to make WSGI calls:

WSGI really is Flask’s "entry point".

Other than that if you’re interested in Flask inner workings start looking from here:
