电子框架上的 Python

Now create the directory where you want all the magic to happen and include following files

创建你的 hello.py:

from __future__ import print_function
import time
from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World! This is powered by Python backend."

if __name__ == "__main__":
   print('oh hello')
    #time.sleep(5)
    app.run(host='127.0.0.1', port=5000)

创建你的基本 package.json:

{
  "name"    : "your-app",
  "version" : "0.1.0",
  "main"    : "main.js",
  "dependencies": {
    "request-promise": "*",
    "electron-prebuilt": "*"
  }
}

最后创建你的 main.js:

const electron = require('electron');
const app = electron.app;
const BrowserWindow = electron.BrowserWindow;
electron.crashReporter.start();

var mainWindow = null;

app.on('window-all-closed', function() {
  //if (process.platform != 'darwin') {
    app.quit();
  //}
});

app.on('ready', function() {
  // call python?
  var subpy = require('child_process').spawn('python', ['./hello.py']);
  //var subpy = require('child_process').spawn('./dist/hello.exe');
  var rq = require('request-promise');
  var mainAddr = 'http://localhost:5000';

  var openWindow = function(){
    mainWindow = new BrowserWindow({width: 800, height: 600});
    // mainWindow.loadURL('file://' + __dirname + '/index.html');
    mainWindow.loadURL('http://localhost:5000');
    mainWindow.webContents.openDevTools();
    mainWindow.on('closed', function() {
      mainWindow = null;
      subpy.kill('SIGINT');
    });
  };

  var startUp = function(){
    rq(mainAddr)
      .then(function(htmlString){
        console.log('server started!');
        openWindow();
      })
      .catch(function(err){
        //console.log('waiting for the server start...');
        startUp();
      });
  };

  // fire!
  startUp();
});
