电子套装曲奇 [英] Electron set cookie

问题描述

我刚接触电子并将Web应用程序转换为桌面应用程序。我正在从文件系统加载页面。如果从Web服务器提供页面，则Cookie可以正常工作，但是当我从本地文件夹加载页面时，我将无法保存它们。我正在使用web中的document.cookie保存cookie。我想知道如何在电子中启用file：// cookie。

I am new to electron and converting an web app to desktop application.I am loading pages from file system.Cookies are working if pages are served from web server but when I load pages from local folder I am not able to save them. I am saving cookie using document.cookie in web.I want to know how I can I enable file:// cookies in electron .

致谢

推荐答案

好的，我知道它可以与Electron 5一起使用下面是基于@ zahid-nisar解决方案的相关内容，下面是完整的示例Electron main.js，以显示它们如何组合在一起。显然，在 mainWindow.loadURL（'app：//www/index.html'）; 中更改应用程序的位置。

OK, I got it working with Electron 5. Below are the relevant bits based on @zahid-nisar's solution, and below that a full sample Electron main.js to show how it all fits together. Obviously, change the location of your app in mainWindow.loadURL('app://www/index.html');.

要插入到main.js中的相关代码：

Relevant code to insert in main.js:

const { protocol } = require('electron');

protocol.registerSchemesAsPrivileged([{
    scheme: 'app',
    privileges: {
        standard: true,
        secure: true
    }
}]);

在 app.on（'ready'）函数：

protocol.registerFileProtocol('app', (request, callback) => {
    const url = request.url.substr(6);
    callback({
        path: path.normalize(`${__dirname}/${url}`)
    });
}, (error) => {
    if (error) console.error('Failed to register protocol');
});

然后，在createWindow函数内部，按如下方式加载应用程序：

Then, inside your createWindow function, load your app like this:

mainWindow.loadURL('app://www/index.html');

最后，这是带有以上代码的完整示例main.js（以及其他功能）我需要的，例如Service Worker）：

// Modules to control application life and create native browser window
const {
    app,
    protocol,
    BrowserWindow
} = require('electron');
const path = require('path');

// This is used to set capabilities of the app: protocol in onready event below
protocol.registerSchemesAsPrivileged([{
    scheme: 'app',
    privileges: {
        standard: true,
        secure: true,
        allowServiceWorkers: true,
        supportFetchAPI: true
    }
}]);

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow;

function createWindow() {
    // Create the browser window.
    mainWindow = new BrowserWindow({
        width: 800,
        height: 600
        //, webPreferences: {
        //     preload: path.join(__dirname, 'preload.js')
        // }
    });

    // and load the index.html of the app.
    mainWindow.loadURL('app://www/index.html');
    // DEV: Enable code below to check cookies saved by app in console log
    // mainWindow.webContents.on('did-finish-load', function() {
    //     mainWindow.webContents.session.cookies.get({}, (error, cookies) => {
    //       console.log(cookies);
    //     });
    // });

    // Open the DevTools.
    // mainWindow.webContents.openDevTools()

    // Emitted when the window is closed.
    mainWindow.on('closed', function () {
        // Dereference the window object, usually you would store windows
        // in an array if your app supports multi windows, this is the time
        // when you should delete the corresponding element.
        mainWindow = null;
    });
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', () => {
    protocol.registerFileProtocol('app', (request, callback) => {
        const url = request.url.substr(6);
        callback({
            path: path.normalize(`${__dirname}/${url}`)
        });
    }, (error) => {
        if (error) console.error('Failed to register protocol');
    });
    // Create the new window
    createWindow();
});

// Quit when all windows are closed.
app.on('window-all-closed', function () {
    // On macOS it is common for applications and their menu bar
    // to stay active until the user quits explicitly with Cmd + Q
    if (process.platform !== 'darwin') app.quit();
});

app.on('activate', function () {
    // On macOS it's common to re-create a window in the app when the
    // dock icon is clicked and there are no other windows open.
    if (mainWindow === null) createWindow();
});

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.
