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();
});
