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();
  });
});
