如果您需要向IP和域发送GET请求（其他答案没有提到您可以指定端口变量），您可以使用此函数：

function getCode(host, port, path, queryString) {
    console.log("(" + host + ":" + port + path + ")" + "Running httpHelper.getCode()")

    // Construct url and query string
    const requestUrl = url.parse(url.format({
        protocol: 'http',
        hostname: host,
        pathname: path,
        port: port,
        query: queryString
    }));

    console.log("(" + host + path + ")" + "Sending GET request")
    // Send request
    console.log(url.format(requestUrl))
    http.get(url.format(requestUrl), (resp) => {
        let data = '';

        // A chunk of data has been received.
        resp.on('data', (chunk) => {
            console.log("GET chunk: " + chunk);
            data += chunk;
        });

        // The whole response has been received. Print out the result.
        resp.on('end', () => {
            console.log("GET end of response: " + data);
        });

    }).on("error", (err) => {
        console.log("GET Error: " + err);
    });
}

不要错过文件顶部的所需模块：

http = require("http");
url = require('url')

还要记住，您可以使用https模块通过安全域和ssl进行通信。因此这两条线将改变：

https = require("https");
...
https.get(url.format(requestUrl), (resp) => { ......

在Express中，这已经为您完成了，您可以简单地使用req.query：

var id = req.query.id; // $_GET["id"]

否则，在NodeJS中，您可以访问req.url和内置的url模块来url.parse它：

var url = require('url');
var url_parts = url.parse(request.url, true);
var query = url_parts.query;

此处保留旧答案：https://gist.github.com/stefek99/b10ed037d2a4a323d638

1） 安装express：npm安装express

应用程序.js

var express = require('express');
var app = express();

app.get('/endpoint', function(request, response) {
    var id = request.query.id;
    response.end("I have received the ID: " + id);
});

app.listen(3000);
console.log("node express app started at http://localhost:3000");

2） 运行app:node app.js

3） 在浏览器中访问：http://localhost:3000/endpoint?id=something

我收到了ID：某物

（自从我的回答以来，很多事情都发生了变化，我相信这是值得的，让事情保持最新）

对于Express.js，您需要执行req.params：

app.get('/user/:id', function(req, res) {
  res.send('user' + req.params.id);    
});

//get query&params in express

//etc. example.com/user/000000?sex=female

app.get('/user/:id', function(req, res) {

  const query = req.query;// query = {sex:"female"}

  const params = req.params; //params = {id:"000000"}

})

你应该可以这样做：

var http = require('http');
var url  = require('url');

http.createServer(function(req,res){
    var url_parts = url.parse(req.url, true);
    var query = url_parts.query;

    console.log(query); //{Object}

    res.end("End")
})
