平时爱看知乎日报，写了个最简单的 **知乎日报** web版，放在了JAE > 2014.05.13更新：更新界面，完善功能，新版本放在了 http://izhihu.jd-app.com （仅在chrome下测试过样式）,原版还在 [这里](http://zhihudaily.jd-app.com) > 2014.04.13更新：增加了 **前一天** 功能，移动设备界面适配，采用巧妙的方式规避了时间格式化问题（取消注释即可下载所有历史文件）代码如下： ``` javascript var http = require('http'); var fs = require('fs'); var date = ''; function fetchBefore(beforeDate) { http.get("http://news.at.zhihu.com/api/1.2/news/before/" + beforeDate, function (res) { if (res.statusCode != 200) return; var data = ''; res.setEncoding('utf8'); res.on('data', function (chunk) { data += chunk; }); res.on('end', function () { var year = beforeDate.substr(0, 4); if (!fs.existsSync(year)) fs.mkdirSync(year); fs.writeFile(year + '/' + beforeDate + '.json', data); //if (beforeDate != '20130520') fetchBefore(JSON.parse(data).date); //fetch all the history stories }); }); } (function fetchLatest() { http.get("http://news.at.zhihu.com/api/1.2/news/latest", function (res) { if (res.statusCode != 200) return; var data = ''; res.setEncoding('utf8'); res.on('data', function (chunk) { data += chunk; }); res.on('end', function () { var json = JSON.parse(data); if (date != json.date) { date = json.date; fetchBefore(date); } fs.writeFile('latest.json', data); }); }); setTimeout(fetchLatest, 10 * 60 * 1000); })(); http.createServer(function (request, response) { var url = request.url; if (url == '/favicon.ico') return; var file = 'latest.json'; if (url.length == 16) { var path = url.substr(8, 4) + '/' + url.substr(8, 8) + '.json'; if (fs.existsSync(path)) file = path; } var data = fs.readFileSync(file); var json = JSON.parse(data); response.writeHead(200, {'Content-Type': 'text/html;charset=utf-8'}); response.write('知乎日报'); response.write(''); response.write(''); response.write('

'); } response.write('
