How can I get JSON data through a URL in page functions?

Question

I hope to use another Python program to get JSON data callback for page functions through URL, for example:

http://127.0.0.1:8080/test

callback:
{
    "id": 1,
    "msg": "msg1",
    "author": "author1",
    "time": "time1"
}

What can i do?

You can simply utilize any python library. I suggest httpx because of it's async-capbailities. See https://github.com/zauberzeug/nicegui/wiki/FAQs#why-is-my-long-running-function-blocking-ui-updates

This is example code:

@ui.page("/ana/a")
def ana_page():
    file = "data/a.json"
    if not os.path.exists(file):
        ana_messages = file_not_found_error(file)
    else:
        with open(file, 'r') as f:
            ana_messages = json.load(f)
        number = random.randint(0, len(ana_messages) - 1)
        print(number)
        ana_messages = ana_messages[number]

    id = ana_messages["id"]
    msg = ana_messages["msg"]
    author = ana_messages["author"]
    time = ana_messages["time"]

    with ui.card().classes("absolute-center"):

        with ui.row():
            ui.badge("id")
            ui.label(id)
        with ui.row():
            ui.badge("语录")
            ui.label(msg)
        with ui.row():
            ui.badge("作者")
            ui.label(author)
        with ui.row():
            ui.badge("时间")
            ui.label(time)

How can I get data on ana_messages?
