Electron as GUI of Python

最近准备做一个离线升级工具，想起前几天刚接触的Electron 决定用它与python相结合来完成

开始准备环境搭建

几经折腾各种zerorpc，zerormq各种报错

历经一天多的网上折腾终于找到一篇实践成功

先看整个流程搭建:

start
 |
 V
+------------+
|            | start
|            +-------------> +-------------------+
|  electron  | sub process   |                   |
|            |               | python web server |
| (basically |     http      |                   |
|  browser)  | <-----------> | (business logic)  |
|            | communication |                   |
|            |               | (all html/css/js) |
|            |               |                   |
+------------+               +-------------------+

 

start
 |
 V
+--------------------+
|                    | start
|  electron          +-------------> +------------------+
|                    | sub process   |                  |
| (browser)          |               | python server    |
|                    |               |                  |
| (all html/css/js)  |               | (business logic) |
|                    |   zerorpc     |                  |
| (node.js runtime,  | <-----------> | (zeromq server)  |
|  zeromq client)    | communication |                  |
|                    |               |                  |
+--------------------+               +------------------+

下来安装步骤（windows）：

Remove-Item "$($env:USERPROFILE).node-gyp" -Force -Recurse -ErrorAction Ignore
Remove-Item "$($env:USERPROFILE).electron-gyp" -Force -Recurse -ErrorAction Ignore
Remove-Item .
ode_modules -Force -Recurse -ErrorAction Ignore

npm install --runtime=electron --target=1.7.6（版本很重要）

这里我直接远程连接的同事的python环境，修改下面文件：

//main.js
let mainWindow = null

const createWindow = () => {
  mainWindow = new BrowserWindow({ 800, height: 600})
  mainWindow.loadURL(require('url').format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))
  mainWindow.webContents.openDevTools()

  mainWindow.on('closed', () => {
    mainWindow = null
  })
}

app.on('ready', createWindow)

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

　　

const zerorpc = require("zerorpc")
let client = new zerorpc.Client()

client.connect("tcp://192.168.200.51:4242")

client.invoke("echo", "server ready", (error, res) => {
  if(error || res !== 'server ready') {
    console.error(error)
  } else {
    console.log(res)
  }
})

let formula = document.querySelector('#formula')
let result = document.querySelector('#result')

formula.addEventListener('input', () => {
  client.invoke("calc", formula.value, (error, res) => {
    if(error) {
      console.error(error)
    } else {
		
      result.textContent = res
    }
  })
})

formula.dispatchEvent(new Event('input'))

　

下来就可以启动：
npm run start
