問題描述

1.這是程序依賴request庫node v6.9.5npm v4.5.0

var request = require(’request’)var fs = require(’fs’)var url = ’http://rest.wufazhuce.com/OneForWeb/one/getHpinfo?strDate=’var d = new Date()var downUrl = url + d.toLocaleDateString()request(downUrl, ((error, res, body) => { var content = JSON.parse(body) // console.log(body) console.log(content.hpEntity.strThumbnailUrl) request(content.hpEntity.strThumbnailUrl).pipe(fs.createWriteStream(content.hpEntity.strHpTitle + ’.jpg’))}))

2.這是請求的json數據

{ 'result': 'SUCCESS', 'hpEntity': { 'strLastUpdateDate': '2017-05-09 11:42:51', 'strDayDiffer': '0', 'strHpId': '1702', 'strHpTitle': 'VOL.1675', 'strThumbnailUrl': 'http://image.wufazhuce.com/FunJK0ZcKgrsYo92v1fK7-v5-ZEN', 'strOriginalImgUrl': 'http://image.wufazhuce.com/FunJK0ZcKgrsYo92v1fK7-v5-ZEN', 'strAuthor': '繪畫', 'strContent': '我希望心里的夏季和身外的夏季一樣完美，讓我忘記終年終日的等待。可是心靈沒有夏季。我望著夏季走過，自己卻留在了冬季。', 'strMarketTime': '2017-05-09', 'sWebLk': 'http://m.wufazhuce.com/one/1702', 'strPn': '', 'wImgUrl': '' }}

問題解答

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

當然是非法的了

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 hereconsole.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’)); }}));回答2：

可以了還是要引用一個日期格式化的小短庫，就用dateformat吧 源碼200多行使用dateFormat(new Date(), 'yyyy-mm-dd')即可獲取2017-05-10格式日期
