Electron 无法获取资源 (.swf)

【中文标题】Electron 无法获取资源 (.swf)

【问题描述】：

我正在使用电子（使用辣椒闪存插件）将 swf 文件直接加载到我的 BrowserWindow 中。 .swf 文件正确加载，但 .swf 文件中的代码请求单独的资源（例如：something.labels）。

由于某种原因，无法请求 something.labels 文件，每次它都会立即失败（屏幕截图）。我无法弄清楚为什么会发生错误，没有提供任何细节......有什么想法吗？

ma​​in.js

const  app, BrowserWindow  = require('electron');
const path = require('path');

// Handle creating/removing shortcuts on Windows when installing/uninstalling.
if (require('electron-squirrel-startup'))  // eslint-disable-line global-require
  app.quit();


// 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;

const createWindow = () => 
  // Create the browser window.
  mainWindow = new BrowserWindow(
    width: 800,
    height: 900,
    titleBarStyle: 'hidden',
    resizable: true,
    autoHideMenuBar: true,

    webPreferences: 
      plugins: true
    
  );

  // and load the index.html of the app.
  mainWindow.loadURL('https://example.org/myapplication.swf');

  // Open the DevTools.
  mainWindow.webContents.openDevTools( mode: 'detach' );

  // Emitted when the window is closed.
  mainWindow.on('closed', () => 
    // 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;
  );
;

app.commandLine.appendSwitch('ppapi-flash-path', path.join(__dirname, 'pepflashplayer.dll'));
app.commandLine.appendSwitch('ppapi-flash-version', '32.0.0.270');

// 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', createWindow);

// Quit when all windows are closed.
app.on('window-all-closed', () => 
  // On OS X 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', () => 
  // On OS X 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();
  
);

【问题讨论】：

不知道——但为了测试，我会尝试在创建BrowserWindow 实例时设置webSecurity: false。

@NoGrabbing 是一个很好的尝试，但没有奏效

【参考方案1】：

对于遇到同样问题的每个人.. 这是 elctron 框架中的一个错误，在版本 7 中引入

将您的电子版本更改为 6.1.2 将解决此问题
