问题描述
我想将我的散景服务器应用程序集成到 Electron 中.所以我所做的是像这样使用 python-shell 运行散景服务器
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() })
这里的问题是窗口永远不会弹出,因为 electron 没有检测到服务器已加载.
The problem here is that the window never pops up because electron does not detect the server as loaded.
推荐答案
我找到了一堆解决方法.我还在等待最终的解决方案.
I have found a bunch of workarounds. I am still waiting for the final solution.
所以我不得不添加这个 setTimeout 作为解决方法.如果我不使用它,页面将永远卡住.
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);
解决方法 2
它检查散景端口是否仍然关闭.但是元素可能没有加载并完全加载
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);
解决方法 3
最后我找到了另一种解决方法来检查是否所有元素都已完全呈现.答案在 这个问题:
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); };
解决方法 4
有一个 GH 问题,作者要求在该问题时调用回调散景已完全加载和渲染.用户 foobarbecue 建议验证散景页面是否使用 MutationObserver,但我没用过.
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.
