下载图片的代码:

const fs = require('fs');
const request = require('request');

request.get('http://farm4.static.flickr.com/3175/2737866473_7958dc8760.jpg').on('error', function(err) {
    console.log(err);
}).pipe(fs.createWriteStream('foo.jpg')).on('close', function() {
    callback(null, dest);
});

console打印的错误信息:

{ Error: read ECONNRESET
    at _errnoException (util.js:1019:11)
    at TCP.onread (net.js:608:25) code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' }

已经翻墙了，用python可以下载啊，图片直接访问也可以显示。
