Nodejs抓取html页面内容（推荐）

废话不多说，直接给大家贴node.js抓取html页面内容的核心代码了。

具体代码如下所示：

var http = require("http");var iconv = require('iconv-lite');var option = { hostname: "stockdata.stock.hexun.com",path: "/gszl/s601398.shtml"}; var req = http.request(option, function(res) {res.on("data", function(chunk) {console.log(iconv.decode(chunk, "gbk"));}); }).on("error", function(e) {console.log(e.message);});req.end();

下面再看下面一种nodejs抓取网页内容

function loadPage(url) {var http = require('http');var pm = new Promise(function (resolve, reject) {http.get(url, function (res) {var html = '';res.on('data', function (d) {html += d.toString()});res.on('end', function () {resolve(html);});}).on('error', function (e) {reject(e)});});return pm;}loadPage('http://www.baidu.com').then(function (d) {console.log(d);});
