我正在尝试使用python脚本更新 Electron 元素。我已经阅读了许多教程,但是大多数教程都无效,而那些有效的教程我不明白如何更改它以在程序中使用它。因此,我创建了一个 Electron 应用程序,该应用程序使用javascript更新了
元素,而另一个应由python更新的
元素。从我阅读的内容中,我需要使用我不知道的flask,这就是为什么我需要有人向我解释如何使用javascript调用python函数以及.py文件中需要的flask代码。这是我的项目的文件:
main.js(由 Electron 伪造自动生成的,通常名为index.js,已重命名)
const { app, BrowserWindow } = require('electron');
const path = require('path');
// Handle creating/removing shortcuts on Windows when installing/uninstalling.
if (require('electron-squirrel-startup')) { // eslint-disable-line global-require
app.quit();
}
const createWindow = () => {
// Create the browser window.
const mainWindow = new BrowserWindow({
width: 1200,
height: 700
});
// and load the index.html of the app.
mainWindow.loadFile(path.join(__dirname, 'index.html'));
// Open the DevTools.
mainWindow.webContents.openDevTools();
};
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow);
// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
// On OS X it's common to re-create a window in the app when the
// dock icon is clicked and there are no other windows open.
if (BrowserWindow.getAllWindows().length === 0) {
createWindow();
}
});
// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and import them here.
index.html(将使用python更新的页面的html文件)<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Test</title>
</head>
<body>
<p id="loadedByJavascript">Loading current value from Javascript</p>
<p id="loadedByPython">Loading current value from python</p>
<script src="index.js">
</script>
</body>
</html>
index.js(将使用python更新的页面的.js文件)var printFromJs = document.getElementById("loadedByJavascript")
var printFromPython = document.getElementById("loadedByPython")
var count = 0
function updateWithJavascript() {
printFromJs.innerHTML = count;
count +=1;
}
updateWithJavascript()
function updateWithPython() {
//I dont know how to call the function hello from hello.py
}
updateWithPython()
//call them every 3 seconds
setInterval(updateWithJavascript, 3000)
setInterval(updateWithPython, 3000)
hello.py(我要调用其hello()函数的python文件)from datetime import datetime
def hello():
return str(datetime.now())
python函数还应该始终返回一个字符串,还是应该返回更复杂的东西(如列表或数据框),并在不同的html元素中使用每个值?感谢您的时间
最佳答案
您可以使用JQuery向Flask路由发出GET请求。
JS:
function updateWithPython() {
$.get('url + /hello', function(data) {
printFromPython.innerHTML = data;
});
}
Python:from flask import Flask
from datetime import datetime
app = Flask(__name__)
@app.route("/hello")
def hello():
return str(datetime.now())
if __name__ == "__main__":
app.run()
