电子-我的应用程序可以与主进程和渲染器进程进行通信吗？ [英] Electron - Can my app communicate with the main and renderer processes?

问题描述

我已经写了一个非常非常基础的电子应用程序-标准的hello world类型，您在那里基本上有一个HTML文件，上面写着 Hello，World，该文件位于电子文件中的 app目录中，然后

I have written a very, very basic electron application - The standard hello world type, where you basically have a HTML file which says "Hello, World" - and that lives in the "app" directory within electron, and then is loaded via main.js when you run the app.

现在，假设我希望能够与这些进程（主要是渲染器）进行通信两者！）都可以从我的应用程序中的javascript中完成吗？我在网上找不到任何东西-但我的主要问题可能是我一开始甚至都不知道要搜索什么。我对Electron很陌生。

Now, lets say I want to be able to maybe communicate with either of those processes (main, or renderer, preferably both!) from the javascript within my application, can that be done? I can't really find anything online about it - but my main problem might be that I don't really even know what to be searching for in the first place. I am very new to Electron.

推荐答案

我想您正在谈论主要过程和其他浏览器窗口。

I suppose you are talking about the main process and other browser windows.

您可以使用 BrowserWindow.webContents.send（channel [，arg1] [，arg2] [，...]）来将消息从主进程发送到浏览器窗口，然后使用 ipcRenderer 接收消息。举个例子：

You can use BrowserWindow.webContents.send(channel[, arg1][, arg2][, ...]) to send messages from the main process to to a browser window, and receive it using ipcRenderer. Take this example:

主流程：

subWindow.webContents.send("foo","bar");

名为 BrowserWindow > subWindow ：

The BrowserWindow called subWindow:

var ipc=require("electron").ipcRenderer;
ipc.on("foo",(event, arg1) => {
    console.log(arg1); //Outputs "bar"
});

要将数据从浏览器窗口发送到主进程时，请使用 remote.app.emit 。使用 app.on 接收它。相同的示例：

When you want to send data from the browser window to the main process, use remote.app.emit. Receive it using app.on. The same example:

主过程：

var app=require("electron").app;
app.on("test",(arg) => {
    if (arg=="hey!") console.log("ha!");
}

子窗口：

require("electron").remote.app.emit("test","hey!");
