白夸克反应很好。但在Node.js和Express.js的当前版本中，它还需要一行代码。确保添加“require-http”（第二行）。我在这里发布了一个更完整的示例，展示了此呼叫的工作原理。运行后，键入http://localhost:8080/?name=abel&fruit=apple在浏览器中，您将根据代码得到一个很酷的响应。

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

app.configure(function(){
    app.set('port', 8080);
});

app.get('/', function(req, res){
  res.writeHead(200, {'content-type': 'text/plain'});
  res.write('name: ' + req.query.name + '\n');
  res.write('fruit: ' + req.query.fruit + '\n');
  res.write('query: ' + req.query + '\n');
  queryStuff = JSON.stringify(req.query);
  res.end('That\'s all folks'  + '\n' + queryStuff);
});

http.createServer(app).listen(app.get('port'), function(){
    console.log("Express server listening on port " + app.get('port'));
})

您可以使用express ^4.15.4：

var express = require('express'),
    router = express.Router();
router.get('/', function (req, res, next) {
    console.log(req.query);
});

希望这有帮助。

如果您正在使用ES6和Express，请尝试以下销毁方法：

const {id, since, fields, anotherField} = request.query;

在上下文中：

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

app.get('/', function(req, res){
   const {id, since, fields, anotherField} = req.query;
});

app.listen(3000);

也可以在析构函数中使用默认值：

//测试样品请求常量要求={查询：{id:'123'，字段：[a'，'b'，'c']}}常量{身份证件，since=new Date（）.toString（），字段=['x']，anotherField='默认'}=请求查询；console.log（id，since，fields，anotherField）

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) => { ......

考虑一下这个url->/api/endpoint/：id？名称=萨希尔这里id是param，其中as name是查询。您可以像这样在nodejs中获取此值

app.get('/api/endpoint/:id', (req, res) => {
  const name = req.query.name; // query
  const id = req.params.id //params
});

//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"}

})
