好的,下面是一个完整的例子:
```
const { download } = require('electron-dl');
const { BrowserWindow } = require('electron');
// 创建一个 BrowserWindow 对象
let win = new BrowserWindow();
// 下载选项
const options = {
directory: '/path/to/save',
onProgress: progress => {
console.log(`Download speed: ${progress.bytesPerSecond}`);
console.log(`Downloaded ${progress.percent}%`);
console.log(`Time remaining: ${progress.timeRemaining} seconds`);
}
};
// 下载文件
download(win, 'https://example.com/file.zip', options)
.then(dl => {
console.log('Download started');
// 监听开始
dl.on('started', () => {
console.log('Download started');
});
// 监听进度
dl.on('progress', progress => {
console.log(`Download speed: ${progress.bytesPerSecond}`);
console.log(`Downloaded ${progress.percent}%`);
console.log(`Time remaining: ${progress.timeRemaining} seconds`);
});
// 监听完成
dl.on('completed', downloadItem => {
console.log('Download completed');
});
})
.catch(err => {
console.log(`Download failed: ${err}`);
});
```
你可以将以上代码保存为一个 js 文件,然后在 Electron 应用中引入该文件,即可执行下载操作。注意替换下载链接和保存路径为你自己的值。
