Answer 1

downUrl = http://rest.wufazhuce.com/OneForWeb/one/getHpinfo?strDate=5/10/2017

Of course it’s illegal

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

var url = 'http://rest.wufazhuce.com/OneForWeb/one/getHpinfo?strDate=';
var d = new Date();
var downUrl = url + encodeURIComponent(d.toLocaleDateString());  // updates go here

console.log(downUrl);

request(downUrl, ((error, res, body) => {
    if (error) {
        console.error(error);
    } else {
        var content = JSON.parse(body);
        console.log(util.inspect(content, { colors: true, depth: 100 }));

        //console.log(content.hpEntity.strThumbnailUrl);
        //request(content.hpEntity.strThumbnailUrl).pipe(fs.createWriteStream(content.hpEntity.strHpTitle + '.jpg'));
    }

}));

Answer 2

Okay
You still need to refer to a short library for date formatting, just use dateformat. The source code is more than 200 lines
Use dateFormat(new Date(), "yyyy-mm-dd") to get the 2017-05-10 format Date
