用Electron打开外部文件

问题描述

我有一个正在运行的Electron应用程序，到目前为止运行良好。对于上下文，我需要运行/打开一个外部文件，该文件是Go-lang二进制文件，它将执行一些后台任务。
基本上，它将充当后端并公开Electron应用程序将使用的API。

I have a running Electron app and is working great so far. For context, I need to run/open a external file which is a Go-lang binary that will do some background tasks.Basically it will act as a backend and exposing an API that the Electron app will consume.

到目前为止，这就是我要学习的内容：

So far this is what i get into:

• 我尝试使用，但由于路径问题，我无法打开示例txt文件。

• I tried to open the file with the "node way" using child_process but i have fail opening the a sample txt file probably due to path issues.

Electron API公开了事件，但缺少文档/示例，我不知道它是否有用。

The Electron API expose a open-file event but it lacks of documentation/example and i don't know if it could be useful.

就是这样。
我如何在Electron中打开外部文件？

That's it.How i open an external file in Electron ?

推荐答案

有一些api您可能想学习

There are a couple api's you may want to study up on and see which helps you.

模块可让您打开文件以直接进行读写。

The fs module allows you to open files for reading and writing directly.

var fs = require('fs');
fs.readFile(p, 'utf8', function (err, data) {
  if (err) return console.log(err);
  // data is the contents of the text file we just read
});

路径

模块允许您在平台中构建和解析路径

path

The path module allows you to build and parse paths in a platform agnostic way.

var path = require('path');
var p = path.join(__dirname, '..', 'game.config');

shell

api是电子

shell

The shell api is an electron only api that you can use to shell execute a file at a given path, which will use the OS default application to open the file.

const {shell} = require('electron');
// Open a local file in the default app
shell.openItem('c:\\example.txt');

// Open a URL in the default way
shell.openExternal('https://github.com');

child_process

假设您的golang二进制文件是可执行文件，那么您将使用调用它并与之通信。这是一个节点api。

child_process

Assuming that your golang binary is an executable then you would use child_process.spawn to call it and communicate with it. This is a node api.

var path = require('path');
var spawn = require('child_process').spawn;

var child = spawn(path.join(__dirname, '..', 'mygoap.exe'), ['game.config', '--debug']);
// attach events, etc.

插件

如果您的golang二进制文件不是可执行文件，则您需要制作一个包装器。
