Javascript 看不到 python 函数暴露在 eel 中

Question

我按照文档中的方式使用了@eel.expose，但是它不起作用。我正在尝试将有关天气的信息从 pyowm 发送到 javascript，但 javascript 无法识别 python 函数。这是我的 python 代码：

import eel
import pyowm

owm = pyowm.OWM("78e8414197f287eb489f857bf10fa96a")

eel.init("web")
eel.start("main.html", size=(700, 700))


@eel.expose
def getWeather(place):
    mgr = owm.weather_manager()
    observation = mgr.weather_at_place(place)
    w = observation.weather

    temp = w.temperature('celsius')['temp']

    return temp

和html代码：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>Weather</title>
        <script type="text/javascript" src="/eel.js"></script>
        <link rel="stylesheet" type="text/css" href="main.css">
    </head>
    <body>
        <input type="text" id="location" placeholder="Enter city and country" required="" value="New York, USA">
        <button id="getWeatherButton">GET WEATHER</button>
        <div id="result"></div>
        
        <script type="text/javascript">
            document.getElementById("getWeatherButton").onclick = async function displayWeather() {
                let place = document.getElementById("location").value;
                let temp = await eel.getWeather(place)();

                document.getElementById("result").innerHTML = temp;
            };
        </script>
    </body>
</html>

Answer 1

eel.start() 必须在代码的末尾这是正确的代码：

import eel
import pyowm

owm = pyowm.OWM("78e8414197f287eb489f857bf10fa96a")

eel.init("web")


@eel.expose
def getWeather(place):
    mgr = owm.weather_manager()
    observation = mgr.weather_at_place(place)
    w = observation.weather

    temp = w.temperature('celsius')['temp']

    return temp


eel.start("main.html", size=(700, 700))

Javascript 看不到 python 函数暴露在 eel 中

Javascript can`t see python function exposed with eel

javascript

python

html

eel
