問題描述

我想將我的散景服務器應用程序集成到 Electron 中.所以我所做的是像這樣使用 python-shell 運行散景服務器

I would like to integrate my Bokeh Server Application in Electron. So what I did is to run bokeh server using python-shell like this

mainWindow = new BrowserWindow({
    width: 1000,
    height: 700,
    show: false,
})

var PythonShell = require('python-shell');
var options = {
    mode: 'text',
    pythonPath: 'python3',
    pythonOptions: ['-m'],
    scriptPath: '',
    args: ['serve','bokeh_project/']
};

PythonShell.run('bokeh', options, function (err, results) {
    if (err) throw err;
    console.log('results: %j', results);
});

mainWindow.loadURL('http://localhost:5006');

mainWindow.once('did-finish-load', () => {
    mainWindow.show()
})

這里的問題是窗口永遠不會彈出，因為 electron 沒有檢測到服務器已加載.

The problem here is that the window never pops up because electron does not detect the server as loaded.

推薦答案

我找到了一堆解決方法.我還在等待最終的解決方案.

I have found a bunch of workarounds. I am still waiting for the final solution.

所以我不得不添加這個 setTimeout 作為解決方法.如果我不使用它，頁面將永遠卡住.

So I had to add this setTimeout as a workaround. If I do not use this the page would be stuck forever.

setTimeout(function () {
    mainWindow.show();
    mainWindow.loadURL('http://localhost:5006');
}, 3000);

解決方法 2

它檢查散景端口是否仍然關閉.但是元素可能沒有加載并完全加載

Workaround 2

It checks if the bokeh port is still closed. But the elements may be not loaded and completely loaded

var portscanner = require('portscanner')
var _checkServerStatus = setInterval(function() {
  portscanner.checkPortStatus(5006, '127.0.0.1', function(error, status) {
    if (status == 'open') {  // status = 'open' or 'close'
        clearInterval(_checkServerStatus);
        console.log('Server running');
        mainWindow.loadURL(bokehUrl); 
    }
  });
}, 100);  

解決方法 3

最后我找到了另一種解決方法來檢查是否所有元素都已完全呈現.答案在 這個問題:

oldLog = console.log;
console.log = function (message) {
    if(message.localeCompare('Bokeh items were rendered successfully') == 0){
        window.top.postMessage('show-bokeh-iframe', '*')
        console.log = oldLog;
    }
    oldLog.apply(console, arguments);
};

解決方法 4

有一個 GH 問題，作者要求在該問題時調用回調散景已完全加載和渲染.用戶 foobarbecue 建議驗證散景頁面是否使用 MutationObserver，但我沒用過.

Workaround 4

There is a GH issue where where the writer ask for calling a callback when bokeh is completely loaded and rendered. The user foobarbecue suggests to verify if the bokeh page is rendered with MutationObserver, but I have never used it.
