我在 Electron 中有一个正在工作的开发应用程序,由于这个奇怪的错误,它将拒绝在生产中运行
(node:10285) ProtocolDeprecateCallback: The callback argument of protocol module APIs is no longer needed.
writeOut @ internal/process/warning.js:32
我过去成功地构建了该应用程序并且正在运行,但现在我遇到了这个问题。这是
background.js
Electron 应用程序的文件我认为该错误可能是由该文件中的某些内容引起的'use strict'
import { app, protocol, BrowserWindow } from 'electron';
import { createProtocol } from 'vue-cli-plugin-electron-builder/lib';
import installExtension, { VUEJS_DEVTOOLS } from 'electron-devtools-installer';
import path from 'path';
import './ipc-services';
const isDevelopment = process.env.NODE_ENV !== 'production';
// Scheme must be registered before the app is ready
protocol.registerSchemesAsPrivileged([
{ scheme: 'app', privileges: { secure: true, standard: true } }
]);
async function createWindow() {
// Create the browser window.
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
// Use pluginOptions.nodeIntegration, leave this alone
// See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more info
//If I enable context isolation window.ipcRenderer will stop working also with preload.js script loaded
//contextIsolation: true,
nodeIntegration: process.env.ELECTRON_NODE_INTEGRATION,
preload: path.join(__dirname, 'preload.js'),
icon: path.join(__static, 'icon.png')
}
});
if (process.env.WEBPACK_DEV_SERVER_URL) {
// Load the url of the dev server if in development mode
win.loadURL(process.env.WEBPACK_DEV_SERVER_URL)
if (!process.env.IS_TEST) win.webContents.openDevTools();
} else {
createProtocol('app');
// Load the index.html when not in development
win.loadURL(path.join(__dirname, 'index.html'));
}
}
// Quit when all windows are closed.
app.on('window-all-closed', () => {
// 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', () => {
// 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 (BrowserWindow.getAllWindows().length === 0) createWindow();
})
// 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', async () => {
if (isDevelopment && !process.env.IS_TEST) {
// Install Vue Devtools
try {
await installExtension(VUEJS_DEVTOOLS);
} catch (e) {
console.error('Vue Devtools failed to install:', e.toString());
}
}
createWindow();
});
// Exit cleanly on request from parent process in development mode.
if (isDevelopment) {
if (process.platform === 'win32') {
process.on('message', (data) => {
if (data === 'graceful-exit') {
app.quit();
}
})
} else {
process.on('SIGTERM', () => {
app.quit();
});
}
}
有我可以申请的修复吗?
最佳答案
经过大量研究和调试后,我在代码中发现了两个问题。第一个是 process.env.IS_TEST
未定义,我已从代码中删除了该行。 electron:serve
没有问题模式。生产中出现空白屏幕的主要问题是因为 win.loadURL(path.join(__dirname, 'index.html'))
试图加载 file:
的文件协议(protocol)而不是从应用程序注册的自定义协议(protocol)。
我已经恢复到原始代码并使用了 win.loadURL('app://./index.html')
经过这个小修改后,该应用程序似乎在生产中也可以正常工作。
