如果您想避免表达，请使用以下示例：

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

function func111(req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  var q = url.parse(req.url, true);
  res.end("9999999>>> " + q.query['user_name']); 
}

http.createServer(func111).listen(3000); 

用法：

curl http://localhost:3000?user_name=user1

通过yl

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;

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")
})

您可以使用

request.query.<varible-name>;

//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"}

})

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) => { ......
