In Node.js / Express, how do I "download" a page and gets its HTML?
提问by TIMEX
Inside the code, I want to download "http://www.google.com" and store it in a string. I know how to do that in urllib in python. But how do you do it in Node.JS + Express?
在代码中，我想下载“http://www.google.com”并将其存储在一个字符串中。我知道如何在 python 中的 urllib 中做到这一点。但是你如何在 Node.JS + Express 中做到这一点呢？

Using node.js you can just use the http.request method
使用 node.js 你可以只使用 http.request 方法
http://nodejs.org/docs/v0.4.7/api/all.html#http.request
http://nodejs.org/docs/v0.4.7/api/all.html#http.request
This method is built into node you just need to require http.
此方法内置于节点中，您只需要要求 http。
If you just want to do a GET, then you can use http.get
如果你只想做一个 GET，那么你可以使用 http.get
http://nodejs.org/docs/v0.4.7/api/all.html#http.get
http://nodejs.org/docs/v0.4.7/api/all.html#http.get
var options = {
host: 'www.google.com',
port: 80,
path: '/index.html'
};
http.get(options, function(res) {
console.log("Got response: " + res.statusCode);
}).on('error', function(e) {
console.log("Got error: " + e.message);
});
(Example from node.js docs)
（来自 node.js 文档的示例）

var util = require("util"),
http = require("http");
var options = {
host: "www.google.com",
port: 80,
path: "/"
};
var content = "";
var req = http.request(options, function(res) {
res.setEncoding("utf8");
res.on("data", function (chunk) {
content += chunk;
});
res.on("end", function () {
util.log(content);
});
});
req.end();

Simple short and efficient code :)
