问题描述
我是开发人员的新手,我在网上搜索了很多东西,但我认为我的项目有问题,我尝试从任何地址下载文件的所有操作均不起作用。
我在Mac上启动了项目,一切正常,我按照此步骤下载了文件:https://ourcodeworld.com/articles/read/228/how-to-download-a-webfile-with-electron-save-it-and-show-download-progress
它确实工作得很好,但是知道,我不得不在窗户上工作,而且此功能已不再起作用,我尝试的所有操作,下载都为0字节。
return new Promise(function (resolve,reject) {
// Save variable to kNow progress
let received_bytes = 0;
let total_bytes = 0;
let req = request({
method: 'GET',uri: configuration.remoteFile
});
let out = fs.createWriteStream(configuration.localFile);
req.pipe(out);
req.on('response',function (data) {
// Change the total bytes value to get progress later.
total_bytes = parseInt(data.headers['content-length']);
});
// Get progress if callback exists
if (configuration.hasOwnProperty("onProgress")) {
req.on('data',function (chunk) {
// Update the received bytes
received_bytes += chunk.length;
configuration.onProgress(received_bytes,total_bytes);
});
} else {
req.on('data',function (chunk) {
// Update the received bytes
received_bytes += chunk.length;
});
}
req.on('end',function () {
let stringDownload = 'fichiers téléchargés';
updateVisualStatus(total,number,stringDownload);
resolve();
});
});
`
我尝试用console.log记录此函数中发生的所有事件,但似乎并没有在Windows上进行,请问为什么? 或者,如果soemone有更好的选择来下载文件。非常感谢,
for (let i = 0; i < arrayTodownload.length; i++) {
//Todo UNCOMMENT THIS
if (arrayTodownload[i] !== "blank") {
if (arrayTodownload[i].startsWith('http') === false) {
await downloadFile({
remoteFile: serverAdress + arrayTodownload[i],localFile: fileFolder + arrayTodownload[i],onProgress: await function (received,total) {
let percentage = (received * 100) / total;
console.log(percentage + "% | " + received + " bytes out of " + total + " bytes.");
}
},arrayTodownload.length,i).then(function () {
if (i === arrayTodownload.length - 1) {
storage.removeItem('arrayTodownload');
}
});
}
}
}
