如何使用 Node.js 访问查询字符串

Question

我是 Node.js 的新手。我编写了简单的 Node.js 程序来打印 hello world。而且效果很好。

现在，当我将查询字符串与其一起传递时，它会给出一个错误

Node.js

var http = require("http");

http.createServer(function (request, response) {

   // Send the HTTP header 
   // HTTP Status: 200 : OK
   // Content Type: text/plain
   response.writeHead(200, {'Content-Type': 'text/plain'});

   // Send the response body as "Hello World"
   response.end('Hello World\n'+request.q);
}).listen(8081);

// Console will print the message
console.log('Server running at http://127.0.0.1:8081/');

从浏览器查询

http://127.0.0.1:8081/?q=MrX

它给予

Hello World
undefined

这可能对您有所帮助

    var http = require("http");
    url = require("url"); 
http.createServer(function (request, response) {

   // Send the HTTP header 
   // HTTP Status: 200 : OK
   // Content Type: text/plain
   response.writeHead(200, {'Content-Type': 'text/plain'});

   // Send the response body as "Hello World"
    var _get = url.parse(request.url, true).query; 
    response.end('Here is your data: ' + _get['data']); 
//   response.end('Hello World\n');
}).listen(8081);

// Console will print the message
console.log('Server running at http://127.0.0.1:8081/');
