Question

我是使用node的新手，我正在尝试编写一个简单的应用程序（见下文），但是当我尝试在浏览器中访问它时，它只是永远加载而且什么都没发生。有谁知道如何解决这一问题？我查看了一些网站和其他教程，但到目前为止还没有任何工作。有人告诉我导航到这个链接：http://localhost:8080/?data=put_some_text_here

以下是代码：

    //include http module, add url module for parsing
    var http = require("http"),
        url = require("url");

    //create the server
    http.createServer(function(request, response) {
      //attach listener on end event
      request.on('end', function() {
        //parse the request for arguements and store them in _get variable
        //this function parses the url form request and returns obj representation
        var _get = url.parse(request.url, true).query;
        //write headers to the response
        response.writeHead(200, {
         'Content-Type': 'text/plain'
        });
        //send data and end response.
        response.end('Here is your data: ' + _get['data']);  
      });
    }).listen(8080);

Answer 1

您没有从请求中读取任何数据，因此永远不会调用您的end事件处理程序，这意味着您永远不会结束响应。如果您不关心请求数据，则可以在request.resume();之前完成request.on('end', ...);

Answer 2

你在结束活动中附加监听器但不会触发此事件。

//include http module, add url module for parsing
var http = require("http"),
    url = require("url");

//create the server
http.createServer(function(request, response) {

    //parse the request for arguements and store them in _get variable
    //this function parses the url form request and returns obj representation
    var _get = url.parse(request.url, true).query;
    //write headers to the response
    response.writeHead(200, {
        'Content-Type': 'text/plain'
    });

    //send data and end response.
    response.end('Here is your data: ' + _get['data']);

    //attach listener on end event
    request.on('end', function() {
        //you can do something here
        console.log('Event: Request End', request.url);
    });

}).listen(8080);
