首先是下載
var request = require('request'); var fs = require('fs');.

function downloadFile(file_url , targetPath){// Save variable to know progressvar received_bytes = 0;var total_bytes = 0;var req = request({method: 'GET', uri: file_url});var out = fs.createWriteStream(targetPath);req.pipe(out);req.on('response', function ( data ) {// Change the total bytes value to get progress later.total_bytes = parseInt(data.headers['content-length' ]);});req.on('data', function(chunk) {// Update the received bytesreceived_bytes += chunk.length;showProgress(received_bytes, total_bytes);});req.on('end', function() {console.log('下載成功')}); }

然后是調用

// downloadFile("https://vms-ipad-h5.s3.cn-northwest-1.amazonaws.com.cn/static/media/AUDI.1dd73b80.mp4", __dirname + "/src/assets/videos/AUDI.mp4"); 直接傳入下載的地址，和有用的路徑就行，這里我采用的是path里拿到的當前相對路徑后的相對位置

要監聽下載進度的函數

function showProgress(received, total){var percentage = (received * 100) / total;console.log(percentage + "% | " + received + " bytes out of " + total + " bytes."); }
