批量下载图片:
var fs = require('fs'); var request = require("request"); img.forEach(src => { var writeStream = fs.createWriteStream(src.split('/2019/08/')[1]); var readStream = request(src) readStream.pipe(writeStream); readStream.on('end', function() { console.log('文件下载成功'); }); readStream.on('error', function() { console.log(1); // console.log("错误信息:" + err) }) writeStream.on("finish", function() { console.log("文件写入成功"); writeStream.end(); }); });
